Preface
Most EPA regulatory and research programs have regulations or requirements by
contract clause that govern the conduct of laboratory studies. The GALPs do not
supersede any existing requirements or regulations of EPA's organizations, nor do they
augment them. Some of the GALP provisions guide EPA staff and its agents (contractors
or grantees) to existing EPA requirements such as the System Life Cycle Management,
Chapter 17 of Information Resources Management Policy Manual.
The GALPs are developed from essential principles inherent to sustaining challenges
to the reliability of data. These include traceability, accountability, standardized
procedures, adequate resources, and, importantly, the availability of documentation that
supports conformance with these principles. Each GALP provision embraces at least one
of these principles.
The intended objective of the GALPs is to provide EPA organizations with a set of
benchmarks to examine in light of their needs and established requirements or regulations.
If an organization then determines that changes or additions to their own requirements or
regulations are needed, it is the responsibility of that organization to amend their
requirements or regulations.
The GALPs have been constructed to address realities of 1995. They may be
modified over time to reflect changes in U.S. laws such as the congressionally-mandated
Computer Security Act, requirements by the Office of Management and Budget, and
others. They may also be modified over time to address advances in automated data
management technologies.

Executive Summary
This document describes benchmarks, Good Automated Laboratory Practices
(GALPs), for assuring the reliability of laboratory data. The GALPs are principles and
guidelines to regulations for laboratories that use or are planning to use a wide range of
automated data collection and management systems. The GALPs are EPA's response to
mounting evidence of corruption, loss, and inappropriate modification of computerized
laboratory data by EPA contractors.
The GALPs are a union of Federal regulations, policies, and guidance documents.
Several of the GALP provisions are embodied in EPA's Good Laboratory Practice
Standards (GLPs). The GLPs are regulations that govern the management and conduct
of mostnonclinical laboratory studies submitted to EPA's office of Toxic Substances and
its Office of Pesticide Programs.
Several GALPs are contained in EPA's Information Resource Management (IRM)
policies. These policies prescribe methodologies and practices for using automated data
processing hardware and software. The IRM policies are directed to EPA staff and its
agents (contractors and grantees) and generally implement broader Federal mandates
such as the congressionally-mandated Computer Security Act of 1987, the Office of
Management and Budget Circular A-130, and others. Most of these are also specifically
required by EPA Acquisition Regulations.
This document is divided into two sections. The first chapter formally establishes the
GALPs, describes the purpose they serve, provides background information about
studies that led to their development, and explains their scope and applicability. The
second chapter provides laboratories with additional explanations of each provision and
other relevant information to assist laboratory staff in implementing each applicable
provision.

Acknowledgments
This document culminates a six year program by EPA's Office of Information
Resources Management (OIRM). Numerous experts in national and international
laboratory standards, laboratory automation experts, senior managers and technical staff
in government and private companies provided invaluable support.
Mr. Mickey Cline and Dr. Walter Shackelford, both of OIRM, identified the need for
the program, ensured that resources were provided, offered many valuable suggestions
that helped to focus the program, and provided encouragement when obstacles seemed
insurmountable. Without their support this program likely would not be completed.
Ms. LynnLaubisch's (Durham, NC) contribution to the publication of this document
far exceeded her title, "Micro Graphics Specialist." She is responsible for transforming
what could have been a dull, monotonous and probably difficult-to-follow publication
into a refreshing, easy to read "text book" that enables complex concepts to be easily
accessible to a diverse readership. While a cursory review of the document demonstrates
her skill in page layout, font selection, and icon and diagram creation, a careful reading
of the text is indicative of her oversight in helping to eliminate convoluted sentences and
make the text easily readable.
Ms. Stephanie Taublee, Mr. David Brodish both of Research Triangle Institute (RTI),
and Ms. Terrie Baker, formerly of RTI, deserve most of the credit for the areas of quality
assurance (QA) the GALPs embrace and explain. Their professional QA experience,
dedication, determination and commitment to doing the right thing on time, and their
ability to examine highly charged and sensitive issues from several angles were essential.
Mr. Keith McLaurin of Technology Planning and Management Corporation (TPMC),
Mr. Don Weyel, formerly of TPMC, and Mr. Bill Hampton, a Consultant to TPMC,
instilled a wealth of the discipline of Computer Science to the GALPs. Their knowledge
and experience in automated system design and development, computing and

communication technologies, and the evolving specialized area of computer security
enabled issues related to current computing environments, system life cycle and a myriad
of intricate factors affecting computing security to be thoroughly andaccurately explained
in the document.
Mr. Dexter Goldman of Goldman and Associates enthusiastically supported this
program from its inception. His extensive experience in EPA's Good Laboratory
Practice Standards is reflected in many areas of the document. His critical review of
earlier drafts was essential. He identified and recommended numerous changes not noted
by other reviewers that, though subtle, had profound impact.
Dr. Sandy Weinberg of Weinberg, Sax and Spelton Associates deserves much of the
credit for getting this program started in the right direction. He afforded the program with
an unparalleled wealth of experience in assisting laboratories in complying with national
laboratory standards, auditing laboratory operations, and translating national and
international laboratory guidelines into laboratory operating standards.

Chapter 1 GALP Overview
1. PURPOSE
Most of the health and environmental data EPA uses in its regulatory programs are
analyzed in and reported by laboratories. Increasingly, these laboratories employ
laboratory information management systems (LIMS) to acquire, record, manipulate,
store, and archive their data (see 2.cAi-r .K \r,\ i S>.VICMS). Though many benchmarks are
scattered across EPA's regulatory programs, EPA has no consistent set of standards for
the use of LIMS that promote integrity of laboratory data.
The purpose of the Good Automated Laboratory Practices (GALPs) is to establish a
uniform set of procedures to assure that all LIMS data used by EPA are reliable and
credible.
2. SCOPE AND APPLICABILITY
a. Organizations
The GALPs are applicable to all EPA organizations, personnel, or agents (contrac-
tors and grantees) of EPA who collect, analyze, process, or maintain laboratory data
for EPA. These organizations include the Agency's Regional Laboratories, and
laboratories submitting data through contracts or grants with EPA, including the
Superfund Contract Laboratory Program (CLP). Other organizations who wish to
improve assurance of the integrity of laboratory data where LIMS are used are
encouraged to review and implement applicable GALP provisions (see also
1-1
-------
GOOD AUTOMATED LABORATORY PRACTICES 2185 1995 Ed
8/10/95
b. Relation to Other Regulations and Requirements
Federal regulations, EPA directives, policies, and its contract requirements govern
the activities performed by laboratories that submit data to the Agency. Various
laboratories are involved in the collection and analysis of environmental data and
not all laboratories are subject to the same set of regulations and requirements.
EPA's Contract Laboratory Program sets requirements by explicit clauses and
clauses incorporated by reference in their governing contracts. Similarly, labora-
tories that submit studies in support of the registration or re-registration of
pesticides under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA)
are subject to the Good Laboratory Practice (GLP) Standards [40 Code of Federal
Regulations (CFR) Part 160. Federal Register Vol. 54, No. 158, August 17,1989].
Laboratories that submit studies required by the test rules and negotiated testing
agreements section of the Toxic Substances Control Act (TSCA) are subject to the
GLP regulations at 40 CFR Part 792.
The GALPs include many of the GLP requirements for managing the conduct of
studies. The GALPs supplement the GLPs with Federal and EPA policies that
address automated hardware, software development and operation, electronic
transfer, and systems security. These are collectively referred to by the term
Information Resources Management (IRM) policies. Thus the GALPs integrate
GLP practices and procedures with IRM practices and procedures, to ensure the
integrity of data that are entered, stored, and manipulated by the LIMS (see Figure
1.1).
c. Applicable Systems
The GALPs use the acronym LIMS, laboratory information management system,
to describe the automated laboratory systems that collect and manage data
discussed in this Directive. There is a limitless range of possible configurations of
automated data collection and processing equipment, communication compo-
nents, types of operating system software, database management systems, and
application software that can constitute a LIMS. The GALPs are directed to most
configurations that are involved with entering, recording, manipulating, modify-
ing, and retrieving data.

(See 10. At.Ro\iMs)
Not all automated laboratory systems are LIMS. Automated laboratory systems
that record data but do not allow changes to the data are not LIMS (see Figure 1.2).
For example, an instrument that measures weights and produces or maintains a
readout of the weight is not a LIMS, if the true reading cannot be altered by a person
prior to recording.
The ability to effect changes to original observations or measurements is the factor
in determining whether the automated laboratory system is a LIMS (see Figine
1,3). If data entering automated laboratory systems can be manipulated or changed
in any way by the action of a person prior to being recorded, then that automated
laboratory system is a LIMS.

4. POLICY
It is EPA policy to implement and comply with all applicable information management
laws mandated by Congress, all requirements issued by the Office of Management and
Budget (OMB), all Federal Information Resource Management Regulations (FIRMR)
issued by the General Services Administration (GSA), and all Information Processing
Regulations issued by the National Institute of Science and Technology (NIST).
It is also EPA policy that data collected, analyzed, processed, or maintained to support
health and environmental effects studies be of sufficient accuracy and integrity to
support effective environmental management.
EPA recognizes that absolute data integrity is not possible and that reliability and
defensibility are determined by adherence to principles and practices that contribute to
improving integrity. The GALPs balance risk against cost, incorporating existing
Federal and EPA policies.

6. RESPONSIBILITIES
a. The Office of Information Resources Management (OIRM) shall:
(1) be responsible for developing, establishing, providing, and main-
taining the GALPs.

(2) provide guidance and technical assistance, where feasible and appro-
priate, in implementing and improving the provisions of the GALPs.
b. Each "Primary Organization Head" (defined by EPA Order 1000.24 as the
Deputy Administrator, Assistant Administrators, Regional Administrators, the
Inspector General, and the General Counsel) is responsible for:
(1) complying with all applicable Federal and EPA rules and regulations
affecting the collection, analysis, processing, storage, or maintenance of
LIMS data. These are indicated in each GALP provision by the use of
underlined lettering, such as EPA Information Security Manual.
(2) reviewing the GALPs and taking the necessary measures to implement
appropriate provisions provided in the GALPs that will improve the integrity
of LIMS data.
7. BACKGROUND
a. EPA relies heavily on laboratory data to accomplish its mission. The
accuracy and integrity of these data are essential to EPA's ability to effectively
formulate policy, make decisions, and take action on issues involving public health
and the environment. Laboratory data are therefore critical Agency assets and must
be managed and protected as such.
b. The computer is increasingly replacing and augmenting many manual
operations in the laboratory. Much of the laboratory data now submitted to EPA
have been created, collected, processed, managed, or in other ways manipulated by
LIMS.
c. Laboratory data are exposed to potential loss and misuse from a variety of
accidental and deliberate causes. Cases involving the corruption, loss, and
inappropriate modification of computerized laboratory data provided to EPA have
resulted in debarments, suspensions, fines, and criminal prosecution.
d. EPA's OIRM conducted several studies to assess the automated data
management practices employed by laboratories to ensure data integrity.
Principal findings and recommendations of these studies included:
1-7
-------
GOOD AUTOMATED LABORATORY PRACTICES 2185 1995 Ed.
8/10/95
(1) The integrity of computer-resident data is at risk in many laboratories
providing scientific and technical data to EPA. Inadequate system security,
data verification, standardized procedures, designation of responsibility, and
documentation are to a large extent responsible for these risks.
(2) EPA has no Agencywide policy for laboratories that collect and
manage LIMS data. The laboratories that provide data to EPA are subject to
differing regulations, policies, and contract requirements for the conduct of
studies and management and operation of the laboratory.
(3) In many cases, the requirements that a laboratory must follow in
conducting a study are vague or ambiguous regarding the special concerns
and issues related to LIMS. For example, FIFRA and TSCA GLPs refer to
"recorded data from automated instruments"; however, standards or guid-
ance for performing LIMS risk assessments and LIMS software develop-
ment and modification are not directly addressed in the GLPs.
(4) EPA has no definitive guidelines to aid the Agency's inspectors and
auditors when they inspect laboratories that use LIMS in the conduct of a
study.
(5) The need for Agencywide standards and guidance is recognized and
acknowledged by the laboratory community and LIMS vendors.
(6) Data management practices should be standardized for all laboratories
supporting EPA programs and the Agency should assume the responsibility
for establishing these standards. The guidance and training provided to the
Agency's inspectors and auditors should also be augmented accordingly.
e. In response to the findings of these studies, OIRM initiated the development
oftheGALP. The first draft of the GALP was issued in December 1990. Since
that time, over one thousand copies of the draft GALP document have been
distributed to EPA regional and program offices, other Federal agencies, industry,
associations, and private citizens and groups.
f. OIRM received over 600 individual comments on the first draft of the GALP
document. OIRM additionally contracted for the review of the document by
1-8

subject-area experts in the fields of laboratory data systems, laboratory manage-
ment, systems security, telecommunications, systems development, quality assur-
ance, and information resources management. Document comments received
from all sources were reviewed and evaluated by OIRM in the development of this
final version of the GALP.

GALP Implementation Assistance
The GALP Implementation is based on established data management principles.
1. PRINCIPLES
Control is the essential objective behind most data management principles. Effective
management and operation of an automated laboratory cannot be assured unless use and
design of the LIMS is consistent with principles intended to assure LIMS control.
Although accuracy and reliability of data must be ensured by a control based system of
management, the most effective management systems invoke the participation of those
employees affected by the control process. Most importantly, the GALPs assume
laboratory professionals are personally motivated to follow the principles of their
professions, and that they will take every practical step to ensure the accuracy and the
reliability of the data and analyses produced by their laboratory.
The GALP guidance is built on six principles.
Communication, transfer, manipulation, and the storage/recall process all offer
potential for data corruption. The demonstration of control necessitates the
collection of evidence to prove that the system provides reasonable protection
against data corruption.

8.1 Laboratory Management
1) Personnel
When LIMS Raw Data (see 8.4.1) are collected, analyzed, processed, or main-
tained, laboratory management shall:
1) ensure that personnel clearly understand the function(s) they are to
perform on the LIMS.
EXPLANATION
DISCUSSION
Laboratory management shall be responsible for the use and
management of the LIMS. This necessitates that all LIMS support
personnel and users are completely familiar with their responsibili-
ties and assigned duties. Written job descriptions are necessary.
Laboratory management shall be responsible for ensuring that
appropriate professional hiring and assignment criteria are used,
coupled with appropriate training, to ensure that all users are able
to use the LIMS effectively.
Written position descriptions signed by LIMS support personnel
and users, with accompanying laboratory management signatures,
are a useful vehicle for documenting that personnel clearly under-
stand the functions they are to perform. Because there are not
widespread academic certifications or criteria that ensure system
user competence, most laboratories rely on a three-part strategy for
compliance: 1) Users are provided with clear operating instructions,
manuals, and SOPs to enable them to perform assigned system
functions; 2) Sufficient training to clarify these instructions is
provided to users; 3) Users able to meet operation requirements are
eligible to perform these LIMS functions.

SPECIAL
CONSIDERATIONS
Because of its significance in evaluating the applicability of the

ous to enable employees to readily identify LRD (see c 4 !) so that
each employee knows when the GALPs must be followed.

2) Quality Assurance Unit
When LIMS Raw Data are collected, analyzed, processed, or maintained, labora-
tory management shall:
2) ensure that a Quality Assurance Unit (QAU) monitors LIMS activities as
described in 8.3.
EXPLANATION
Laboratory management shall designate a group or individual as the
QAU. This designation shall be consistent with the provisions set
forth in 8.3. The QAU responsibilities are primarily inspection,
audit, and review of the LIMS and its data.
DISCUSSION
An organizational plan should be developed to define lines of
communication, reporting, inspection, and review of the LIMS and
its data The QAU must be entirely separate from and independent
of the personnel engaged in the direction and conduct of a study, and
should report to laboratory management. In smaller laboratories, a
single individual may have many LIMS managerial responsibili-
ties, but may not be the designated QAU.

as scheduled.
EXPLANATION
DISCUSSION
Laboratory management shall ensure that personnel, resources, and
facilities are adequate to handle LIMS functions and operation in a
timely fashion. Resources include the LIMS equipment, materials,
software, and training.
Laboratory management should ensure that backup staff for critical
functions are available. In laboratories where time-critical func-
tions are frequently encountered, laboratory management should be
particularly sensitive to the need for adequate staff, backup, and
other necessary resources.
Laboratory management should periodically assess the staffing
levels for LIMS supervision, support, and operation, in order to
determine if resources are adequate. Laboratory management may
review training records to maintain awareness of the current status
of training received and needed, observe job performance to deter-
mine the performance levels of current staff and possible needs for
additional training, and examine project schedules and work back-
logs to determine the adequacy of current staff and whether the
LIMS is receiving proper staffing support.

another individual.
When laboratory management delegates LIMS resource assess-
ment, he/she shall ensure that the designated person has the experi-
ence, skills, and education to fulfill the responsibilities. Laboratory
management is also responsible for ensuring that the designated
person is available and has sufficienttime and resources to fulfill the
specific responsibilities. These responsibilities must be fully docu-

When LIMS Raw Data are collected, analyzed, processed, or maintained, labora-
tory management shall:
4) receive reports of QAU inspections of the LIMS (see 8,3,3) and audits of
LIMS Raw Data (see 8,3,5) and ensure that corrective actions are
promptly taken in response to any deficiencies.
EXPLANATION
DISCUSSION
SPECIAL
CONSIDERATIONS
The flow of information concerning all laboratory operations,
including LIMS inspections and LRD audits, should expeditiously
move to laboratory management. Laboratory management should
review QAU inspection reports and audits, and may recommend
remedial actions. It is ultimately the responsibility of laboratory
management to ensure that any errors or deficiencies, discovered
through QAU activities, are acted upon and rectified.
Laboratory policy or SOP should clearly state that all QAU inspec-
tion and audit reports are presented in a timely manner to laboratory
management for review. These reports should have a provision for
laboratory management's signature and date. Likewise, an SOP or
policy should define the responsibility of management to follow up
on all deficiencies found in the QAU report.
A relevant legal concept is that the laboratory should be able to
demonstrate due diligence in carrying out its own rules, not just
have them.

methods that assure LIMS Raw Data integrity, ensure that any deviations
from SOPs and applicable GALP provisions are appropriately
documented and that corrective actions are taken and documented, and
approve subsequent changes to SOPs (see 8.11).
EXPLANATION
DISCUSSION
Laboratory management is ultimately responsible for all activity
within the laboratory, including approval of SOPs and any subse-
quent changes, and implementation of required GALP provisions.
An SOP or laboratory policy should state that any departure from
laboratory SOPs and applicable GALP provisions will be reported
to laboratory management. Laboratory management should then
ensure that the deviation is properly documented and that appropri-
ate corrective actions are taken and similarly documented.
As part of a comprehensive LIMS policy, there should be docu-
mented assurance that laboratory management is made aware of
deficiencies or departures from the laboratory SOPs and required
GALP provisions. The SOP or policy should state that laboratory
management is responsible for ensuring that all deviations are noted
and corrective actions taken and documented.

6) Compliance With GALP Provisions
When LIMS Raw Data are collected, analyzed, processed, or maintained, labora-

6) assure that each applicable GALP provision is followed. With the
exception of 8.1, 8.2, and 8,3, laboratory management may delegate GALP
implementation and compliance to one or more responsible persons.
EXPLANATION
Laboratory management is responsible for complying with each
GALP provision that is required by the EPA program for which data
are submitted. Laboratory management, particularly in large labo-
ratories, may find it necessary to delegate GALP compliance
responsibilities to one or more responsible persons. The GALP
provisions in 8.1, 8.2, and 8.3 may not be delegated.
When GALP compliance responsibilities are delegated, laboratory
management shall ensure that the designated responsible persons
have the experience, skills, and education necessary to fulfill their
responsibilities. Laboratory management is also responsible for
ensuring that designated responsible persons are available and
provided sufficient time and resources to fulfill their responsibili-
ties.
Laboratory management shall ensure that delegation of GALP
compliance responsibilities are fully documented and current. This
documentation shall identify the individual who is assigned respon-
sibility for compliance with each GALP provision and shall clearly
specify each individual's job responsibilities and duties. The
documentation shall be signed by each responsible person to dem-
onstrate that each person is aware of his/her responsibilities.

6) Compliance With GALP Provisions
DISCUSSION
SPECIAL
CONSIDERATIONS
The manner by which GALP compliance responsibilities are dis-
tributed is at the discretion of laboratory management. At small
laboratories, one person may be responsible for compliance with all
GALP provisions. At larger laboratories, responsibilities may be
distributed among a number of people. Larger laboratories might
distribute responsibilities organizationally, functionally, by area of
scientific study, or other methods that meet the laboratory's needs.
It is strongly recommended that secondary responsible persons be
designated. The designation of secondary responsible persons
minimizes disruptions in the event of the prolonged absence of the
primary responsible person.

1) have adequate education, training, and experience to perform assigned
LIMS functions.
EXPLANATION
DISCUSSION
All LIMS support staff and users shall have adequate education,
training, and experience to perform assigned LIMS functions.
This provision encompasses all LIMS functions used to collect,
transmit, report, analyze, summarize, store, or otherwise ma-
nipulate data. Laboratory management is expected to use appro-
priate professional hiring and assignment criteria, coupled with
appropriate training, to ensure that all users are able to use the
LIMS effectively.
In certain cases, specialized training or attendance at special
courses and certification programs may substitute for formal
education requirements. Demonstrated experience may also sub-
stitute for formal education requirements. Either basis for sub-
stitution should be thoroughly and accurately documented. In
certain cases, especially for personnel with advanced education
and training, self-certification may be possible. Laboratory
management should use professional judgment as to the appro-
priateness of self-certification.

tory management shall ensure that all LIMS support staff and users:
2) have a current summary of their training, experience, and job description,
including their knowledge relevant to LIMS design and operation,
maintained at the facility.
EXPLANATION
DISCUSSION
SPECIAL
CONSIDERATIONS
This provision states that documentation of personnel back-
grounds, including education, training, and experience, is cur-
rent and available. Pertinent LIMS design, support, and opera-
tions knowledge for each person with access to and responsibility
for the LIMS should be included in the documentation. Evidence
of training and experience that indicates knowledge sufficient for
job requirements is essential.
Resumes (including references to education and degrees ob-
tained, professional certificates, previous job titles, and respon-
sibilities), reports of completed training, and current job descrip-
tions may be centrally filed at the facility. Job performance
evaluations may be used to demonstrate proper levels of LIMS
knowledge and experience. Documentation of prior success in
similar responsibilities may be sufficient.
When outside vendors are involved, the required education,
training, knowledge, and experience may be so indicated on their
resumes.

3) are of sufficient number for timely and proper operation of the LIMS.
EXPLANATION
DISCUSSION
Laboratory management is expected to maintain a staff that is
adequate in size to ensure that functions for the LIMS will be
performed in an accurate and timely manner, including all sys-
tem-related tasks, and particularly time-critical functions.
By designing and following a work plan for any particular study,
laboratory management can anticipate staffing requirements nec-
essary for a particular need. Laboratory management must be
aware of any delays in operations due to inadequate staffing and
take proper action.
Persistent and excessive overtime, excessive LIMS downtime, or
delayed responses to hardware and software changes may indi-
cate insufficient staffing.
Information regarding the adequate competence of personnel is
discussed in 8,2.1.

1) Independent QAU
When LIMS Raw Data are collected, analyzed, processed, or maintained, labora-
tory management shall designate a Quality Assurance Unit (QAU) to monitor
LIMS functions and procedures. The QAU shall:
1) be entirely separate from and independent of LIMS personnel, and shall
report directly to laboratory management.
EXPLANATION
DISCUSSION
SPECIAL
CONSIDERATIONS
The QAU is responsible for assuring laboratory management of the
integrity of the LRD; therefore, any real or apparent conflict of
interest with LIMS personnel, including LIMS management, shall
be avoided. Because laboratory management is ultimately respon-
sible for compliance with all of the GALPs, the QAU shall necessar-
ily report directly to laboratory management.
Documentation of the organization should be available providing
clear evidence that the QAU reports directly to laboratory manage-
ment. Similarly, descriptions of the positions and responsibilities of
each QAU staff member should be available for review and provide
evidence of their independence from LIMS personnel and manage-
ment. These descriptions should also provide evidence of the role
of QAU staff members in monitoring LIMS activities to assure LRD
integrity. Organizational charts and job descriptions may be useful
in providing this documentation.
In LIMS operations where the number of personnel is small, there
could be a real or apparent conflict of interest between the QAU and
LIMS personnel and managers. In these situations, an extramural
QAU may be required in the absence of alternative solutions to
resolving the real or apparent conflict of interest.

2) have immediate access to the LIMS data, SOPs, and other records
pertaining to the operation and maintenance of the LIMS.
EXPLANATION
A complete and current set of SOPs shall be available and accessible
at all times to the QAU. The QAU should also have access to the
most current and version-specific set of LIMS operations and
maintenance manuals, data, and other operations and maintenance
documentation.
DISCUSSION
SPECIAL
CONSIDERATIONS
A complete and current copy of LIMS SOPs and technical documen-
tation should exist as part of standard documentation and be acces-
sible to the QAU. Documentation of the procedures described above
may be set forth in SOPs and/or LIMS management policy. The
documentation may be in writing or electronically maintained.
If SOPs are stored electronically, the QAU shall be responsible for
verify ing that they are secure, retrievable, and readable; maintaining
a hard copy of the electronic versions; and ensuring that the hard
copy versions are identical to the electronic versions.

3) Inspections
When LIMS Raw Data are collected, analyzed, processed, or maintained, labora-
tory management shall designate a Quality Assurance Unit (QAU) to monitor
LIMS functions and procedures. The QAU shall:
3) inspect the LIMS at intervals adequate to ensure the integrity of the LIMS
Raw Data (see 8,3.5); prepare inspection reports that include a description
of the LIMS operation inspected, the dates of the inspection, the person
performing the inspection, findings and problems observed, action
recommended and taken to resolve existing problems, and any scheduled
dates for reinspection; and report to laboratory management any
problems that may affect data integrity.
EXPLANATION
A LIMS that is consistently reliable and accurate is a major goal of
QAU activity. To assure reliability and accuracy, the LIMS must be
inspected on a regular basis. Inspection shall be performed at a
frequency adequate to ensure the integrity of the LRD. The LIMS
shall also be inspected immediately after any change to LIMS
software or hardware.
Records of each inspection shall be prepared and maintained and
shall include the following: the specific LIMS operation inspected,
the name of the inspector, and the date of the inspection. Findings
from the inspection and any problems observed shall be recorded.
Actions recommended and those taken to resolve any problems that
were found and scheduled dates for reinspection shall be docu-
mented. In all cases where problems affecting the integrity of LRD
were observed during inspection, these problems shall be immedi-
ately reported to laboratory management. Documentation of reports
to laboratory management should be maintained.

DISCUSSION
Although the QAU is responsible for reporting directly to labora-

LIMS functions and procedures. The QAU shall:
4) determine that no deviations from approved SOPs were made without
proper authorization (see 8J.5) and sufficient documentation.
EXPLANATION
DISCUSSION
The QAU shall ensure that no deviations from S OPs have been made
without prior authorization and complete documentation of the
change. Authorization for the planned deviation entails obtaining
the approval, signature, and date of laboratory management prior to
its occurrence. Documentation of any deviation shall include, but
not be limited to: an explanation of the departure from methods
established in the SOP, the reason for the departure, and the accom-
panying date of the departure.
In order to maintain complete control over LIMS operations and
functions, it is important to ensure that the LIMS is consistently
operated in compliance with approved SOPs.
In certain situations, unplanned deviations from the SOPs may
occur. These deviations must be documented and include the
explanation of the departure from the methods established in the
SOPs, the reason for the departure, the signature and date of
laboratory management, and its affect on the LIMS data.

5) LIMSRaw Data Audit
When LIMS Raw Data are collected, analyzed, processed, or maintained, labora-
tory management shall designate a Quality Assurance Unit (QAU) to monitor
LIMS functions and procedures. The QAU shall:
5) periodically audit the LIMS Raw Data to ensure their integrity.
EXPLANATION
Periodic review of LRD that are being reported or will be reported
are conducted to ensure the integrity and reliability of the LRD. By
examining reported data and correlating it with the LRD for a
specific LIMS reporting activity, the QAU will ensure the integrity
of LRD.
DISCUSSION
An audit should be undertaken if QAU inspection problems
are found that jeopardize LRD integrity. It is recommended
that an SOP be established that requires periodic review of final
reports and their corresponding LRD. Integrity problems or devia-
tions arising from these audits should be reported to laboratory
management as discussed in 8,3.3.
If LIMS hardware or software are changed or relocated consistent
with 8.7,2 and 8.5,2, a review of reportable data against LRD is
recommended.
SPECIAL
CONSIDERATIONS
Movement of non-LIMS equipment, particularly those emitting
magnetic radiation in close proximity to LIMS equipment, may
affect LRD integrity. In these situations, it is strongly recommended
to also review reported data against the LRD.

6) ensure that the responsibilities and procedures applicable to the QAU, the
records maintained by the QAU, and the method of indexing such records
are documented and are maintained.
EXPLANATION
DISCUSSION
The methods and procedures of the QAU shall be fully documented,
consistently followed, and maintained by the QAU. The method of
indexing such records shall also be documented and maintained.
It is important that the QAU inspection and audit reports discussed
in 8.3.3 and 8,3.5 are identified and maintained to include date, time,
and investigator(s). The complete set of documentation, including
QAU responsibilities and procedures and their inspection reports
should be indexed so as to be readily accessible.
Because the QAU must maintain all records and documentation
pertaining to their activities, a policy or SOP may be developed to
establish specific procedures for this.

8.4 LIMS Raw Data
1) Identification and Documentation
Laboratory management shall ensure that:
1) LIMS Raw Data (LRD) and LRD storage media on which they reside
(see 9. DEFINITIONS LIMS Raw Data and LIMS Raw Data storage media)
are identified and documented. This documentation shall be included in
the laboratory's SOPs.
EXPLANATION
DISCUSSION
The objective of the GALPs is to provide EPA with assurance of the
integrity of LIMS Raw Data (LRD). Thus the GALPs prescribe how LRD
are to be entered, changed, stored, and secured. Laboratory management
or designee (see 8.1.6) shall assess data that are entered in, processed,
maintained, or reported by the LIMS to identify and document those data
that are LRD. The documentation shall also include a description of the
LRD storage medium. LRD and their respective storage media shall be
identified in the laboratory's SOPs. Copies of the SOPs shall be made
available to all personnel with access to LRD, and laboratory management
should assure that these personnel clearly understand the importance of
LRD.
LRD are original observations recorded by the LIMS that are needed to
verify, calculate, or derive data that are or may be reported. Original
observations mean the first occurrence of human-readable information.
The media to which the LRD are first recorded is the LRD storage media.
The media may be paper, microfiche, microfilm, magnetic or optical
storage media.
As an example: Person A places an environmental sample into a labora-
tory instrument that analyzes the sample and transmits signals to a
personal computer (PC). The PC software captures the signals, analyzes
them, and displays a graphical representation of the analyzed signals on
a monitor. Person B examines the graphic, concludes it is realistic, and
then issues a command to the PC software to record the analyzed data on
a disk. The data stored on the disk are the LRD, and the disk is the LRD
storage medium. The instrument, communications components, PC, PC
software, monitor, recording device, and disk are a LIMS (see Figure 1.3).

8.4 LIMS Raw Data
1) Identification and Documentation
SPECIAL
CONSIDERATIONS
Alternatively, Person B could issue a command to first record the
analyzed signal to paper before it is recorded to disk. In this case, the paper
is the LRD storage medium.
The documentation for the above example may be an SOP or SOPs that
describe data entry, analysis, and recording. For example, a single SOP
could be developed and maintained that documents data entry, analysis,
and recording. It would specify recording of the instrument. Person A,
time and date, and Person B, time and date, on the disk, and that the LRD
and LRD storage medium are those recorded by Person B on the disk (or
paper, depending on which the LRD are first recorded).
1. Some EPA programs may require additional data beyond those
discussed in the example above. To demonstrate the reliability of
instrumentation, an EPA program may also require that the initial
high and low values sent from the instrument to the LIMS be
included with the LRD discussed in the example.
2. Original observations that have been recorded prior to entry to the
LIMS (see Figure 1.2) are not LRD (see 3. below). However,
laboratory management may want to extend the definition of LRD to
include these observations, thus ensuring that they are GALP-
compliant.
3. For 2. above, some EPA programs require that the original observa-
tions be maintained and stored on their original recording medium.
For example, the GLPs define raw data as any laboratory worksheets,
records, memoranda, notes, or exact copies thereof, that are the result
of original observations and activities of a study and are necessary
for the reconstruction and evaluation of the report of that study.

2) Entry and Recording Person
Laboratory management shall ensure that:
2) the individual(s) responsible for entering and recording LIMS Raw Data is
(are) uniquely identified when the data are recorded, and the time(s) and
date(s) are documented.
EXPLANATION
DISCUSSION
SPECIAL
CONSIDERATIONS
Laboratory management shall ensure that LRD input is traceable to
the person who manually input the LRD or who was responsible for
transmission to the LIMS, and, if different, the person who was
responsible for the recording of the LRD by the LIMS. The time and
date for each of these actions shall also be documented.
The usual method for accomplishing this identification is to have the
LIMS record a unique user identification code as part of the data
being entered or recorded. The user ID code can then be referenced
back to the associated data entry or data recording person to allow
identification of all entered data.
The person who operated the instrument may not be same as the
person who transmitted the data. Knowing who operated the
instrument, however, may be as important as knowing who entered
or recorded the data into the LIMS. Thus, the laboratory should also
document the instrument operator with the data entry/recording
person(s). Laboratory management should ensure that the time and
date for each action above is correct and has not been altered in an
unapproved manner.
In the case of manual entry, the original data generally are study raw
data (see 8.4.1 Special Considerations) and can be audited; the LRD
are derived data.

This can be accomplished by including a unique instrument identi-
fication code that also documents the date and time during transmis-
sion to the LIMS and records this information with the LRD.

reason for the change, identify the person who made the change and, if
different, the person who authorized the change. These procedures shall
be included in the laboratory's SOPs, and managed as described in 8.11.
EXPLANATION
DISCUSSION
SPECIAL
CONSIDERATIONS
When LRD are changed after initial recording, documentation shall exist
that preserves the original recorded required documentation (see 8.4.2 and
8,4.3), provides clear evidence that a change was made, explains the
reason for the change, records the date of change, the person who made the
change and, if different, the person who authorized the change. The
laboratory's SOPs shall include procedures for making changes to LRD
in compliance with these recording requirements, and shall specify who
has authority to make changes or to authorize changes, if different. These
procedures shall be included hi the laboratory's SOPs, and shall be
established, approved, and managed as described in 8.11.
This GALP provision requires maintaining all LRD and changes to LRD
so that all modifications are clearly documented. All documented changes
shall be stored and retained as specified in H.9 and 8.10.2. If LRD are
purged from the LIMS, a verified copy of the LRD should be maintained,
for at least the required retention period.
Recording both a person authorizing a change and a different person
entering a change may not be feasible in an existing LIMS. To obviate this
problem, laboratories may consider establishing a policy by which only
one individual has authority to authorize changes and make changes to
data on the LIMS. An alternative may be to retain paper copy authoriza-
tions or logs.

EXPLANATION
DISCUSSION
An SOP shall be prepared for LIMS software development method-
ology. In preparing this SOP, all GALP provisions, especially 8,4
and 8.6, should be considered. EPA Information Resources Man-
agement Policy Manual. Chapter 17. serves as software develop-
ment guidance for the Agency. The methodology set forth in this
guide shall be used by EPA and its agents (contractors and grantees)
when developing software. If an EPA office has supplemented EPA
Information Resources Management Policy Manual with its own
guidance, the laboratory must consider the applicability of this
specific guidance to the software to be developed. The SOP
documenting the development methodology shall be established,
approved, and managed as described in 8.11.
When selecting a LIMS software development methodology, the
laboratory's goal is the reliability of LIMS Raw Data. The method-
ology and techniques selected should contribute to the software's
accuracy and reliability in meeting user needs. In most cases, the
methodology should include user involvement throughout the de-
velopment cycle.
Laboratory management should consider several factors in selecting
the development methodology. A large system that will be used for
several years by many users is a good candidate for the full develop-

accurately performs its intended functions, including: acceptance
criteria, tests to be used, personnel responsible for conducting the tests,
documentation of test results, and test review and approval.
EXPLANATION
DISCUSSION
SOPs shall be prepared for conducting and documenting testing and
quality assurance. Testing and quality assurance involves evaluat-
ing new or changed software to determine that it performs correctly
and meets user requirements. SOPs shall document when testing
and quality assurance are required, as well as how they are to be
conducted, the acceptance criteria, personnel responsible for test-
ing, and documentation of test results, test review, and approval.
Testing and quality assurance are specified in EPA Information
Resources Management Policy Manual. Chapter 17. SOPs for
testing and quality assurance shall be established, approved, and
managed as described in 8.1!.
Testing and quality assurance procedures are standard integral parts
of the change control process, that also apply to implementation of
new software. Users should be involved in testing programs in an
environment that will not affect the production system. New
software should also be tested in a similar way by potential users.
Acceptance criteria should be documented before testing begins to
ensure that testing is predicated on meeting those standards, as
discussed in 8,5.2.2. SOPs may include provisions for laboratory
management to review the tests and results to ascertain that criteria
are appropriate and are met to their satisfaction.

3) Change Control
DISCUSSION
Change control procedures should also be tailored to handle changes
of different priorities. For example, procedures for dealing with
emergency problems should expedite corrective action. The labora-
tory should consider a centralized change control system (manual or
automated) that includes all change requests, including emergency'
problems, corrections to software errors, and enhancement requests.
A centralized change control system may allow better tracking and
control than separate systems. The change control procedure should
designate a person authorized to move changed program versions to
the production environment.
Problem report forms with written instructions for completion may
be developed, and problem logs may be maintained by a designated
person. Analysis and initial reporting may be required within a
specific time frame and may be performed by the responsible person
until resolution is reached.

When software is used to collect, analyze, process, or maintain LIMS Raw Data,
laboratory management shall ensure that:
2) documentation is established and maintained to demonstrate the validity
of software used in the LIMS:
1) for existing and commercially-available LIMS, minimum documentation
shall include, but not be limited to: a description of the software and
functional requirements; listing of all algorithms and formulas; and, as
they occur, testing and quality assurance, installation and operation,
maintenance/enhancement, and retirement.
EXPLANATION
DISCUSSION
To demonstrate the validity of software used, LIMS software
documentation should include, within practical limits, all phases of
the software life cycle (see 8.5,2.2). For existing and commercially-
available LIMS software, the minimum documentation shall in-
clude:
A. LIMS software description and functional requirements
13. algorithms and formulas
C. testing and quality assurance procedures
D. installation and operation, maintenance/enhancement, and
retirement procedures
For commercially-available software and LIMS software in use
prior to publication of the GALPs, the documentation of additional
life cycle phases is governed by the magnitude of the programming
effort involved in creating the software. Large, complex applica-
tions that require lengthy and expensive software development
efforts necessitate an equivalent level of effort in the creation of
detailed documentation that describes the application throughout
each software life cycle phase. A small, less detailed program
written by one programmer in a short period of time (such as a

week), requires less documentation that may involve only a para-
graph describing each phase of the software life cycle.
For existing or commercially-available LIMS software, documenta-
tion may be difficult to obtain. However, LIMS software descrip-
tions and functional requirements can be developed. User require-
ments that lead to the purchase of a commercially-available LIMS
can be used to develop the functional requirements documentation.
Software vendors may provide some LIMS software design docu-
mentation, but for proprietary reasons, it may not be complete. File
layouts, program descriptions, and functional specifications may be
provided, but program specifications and source code may be
unavailable. If the minimum documentation described above is not
provided, an attempt to obtain it from the vendor should be made;
however, it may be necessary to reconstruct it in-house.
A. LIMS Software Description and Functional Requirements
A description shall be documented and maintained for the LIMS
software that provides detailed information on the functions the
software performs. Depending on the nature or internal structure of
the software, the documentation for the functional requirements
may include: flowcharts or block diagrams that illustrate step-by-
step processing of a software module, data flow diagrams that
illustrate the movement of data through the LIMS, or entity-
relationship diagrams that illustrate the relationship of the data
within the database,
B. Algorithms and Formulas
All algorithms and formulas used in the LIMS, and modules that
allow user entry of formulas or algorithms, shall be documented and
retained. Documentation of the algorithms and formulas should be

easily discernible. These listings should identify the locations in
which the formulas and algorithms occur in the LIMS software.
Documentation for all such formulas and algorithms can be main-
tained in a central location. In some cases, formulas and algorithms
for purchased software may be obtained from vendor-provided
documentation. For software currently in use, it may be possible to
extract the formulas and algorithms from source code.
C. Testing and Quality Assurance
Documentation shall be established and maintained to support
testing and quality assurance. The documentation should describe
procedures that ensure the LIMS works as intended and that it meets
organizational standards for performance, reliability, integrity, and
availability. Testing documentation should include evidence of
integration and validation testing. Test specifications and results
(unit tests, system tests, integration tests) should be documented
and maintained.
D. Installation and Operation, Maintenance/Enhancement,
and Retirement Procedures
Documentation shall be established and maintained to support the
initial and continuing operations of the LIMS software. The docu-
mentation includes implementation plans and procedures,
methods for regulating and controlling software changes (see
8,5.1.3), routine support requirements, and post-implementation
reviews. Retirement plans and procedures identify a means of
retrieving LIMS data after the LIMS is replaced or is no longer
operational.

EXPLANATION
The goal of LIMS software documentation efforts shall be to demonstrate
the validity of the software used. The documentation shall accurately
describe the software's functions and internal structures as they exist, or
will exist, during each of the software life cycle phases. The terms used
to describe each software life cycle phase have varied over time and have
been published using different "standard" terminology However, the
general structure and progression of the software life cycle has remained
the same for many years.
For new LIMS software (under development, or to be developed) used in
EPA-sponsored studies, laboratories shall establish and maintain life
cycle documentation that conforms to the specifications of EPA Informa-
tion Resources Management Policy Manual. Chapter 17. The extent of
the documentation shall be consistent with the software application's size,
cost, sensitivity of data, policy implications, and diversity of organiza-
tions using the LIMS. New LIMS software documentation should
generally include the following, which are intended to cover all phases of
the software life cycle:

2) Documentation
2) New Systems
SOPs may be established and maintained to ensure that each phase of the
software life cycle is documented. Laboratory management review of
milestones ensures that required documentation is available before giving
approval for LIMS software development to proceed.
Documentation standards for initiation and requirements analysis can be
established. The initiation documentation can include a request for LIMS
development or enhancement, and the needs that are resolved. The
requirements analysis documentation identifies the functions that the
LIMS will perform.
Design and programming standards ensure that minimum requirements
are met and foster consistency and uniformity in the software. File layout
formats, screen formats, and report formats can be included in the design
standards. Explanatory comments, section and function labels, the pro-
gramming language, identification of the programmer, dates of original
writing and all changes, the use of logical variable names, and other
programming documentation requirements are established by the pro-
gramming standards.
Testing and quality assurance standards ensure that the LIMS performs as
it was intended. Testing and quality assurance include both unit and
integration testing. It assures that the LIMS meets standards for perfor-
mance, reliability, integrity, and security.
Installation and operation standards assure a smooth transition from
existing laboratory operations to the LIMS. Maintenance/enhancement
standards improve the continuing operation of the LIMS. The mainte-
nance/enhancement procedures identify change control procedures for
resolving problems not discovered during testing, improving LIMS per-
formance, and modifying the LIMS to meet changing needs or new
requirements. The retirement standards identify procedures for ending
use of the LIMS due to obsolescence or replacement. The retirement
procedures identify a means of retrieving historical LIMS data.

EXPLANATION
DISCUSSION
Requirements for protecting LIMS data from destruction, disclo-
sure, alteration, delay or undesired manipulation can vary greatly
according to laboratory needs and requirements. Laboratory man-
agement is responsible for ensuring that threats to the LIMS and its
data have been assessed, compensating safeguards implemented,
and, where required, other established security requirements imple-
mented.
EPA's Information Security Policy (described in EPA Information
Resource Management Policy Manual, Chapter 8) formally estab-
lishes a comprehensive, Agency wide information security program.
This policy implements OMB Circular A-130 and describes indi-
vidual and organizational responsibilities for EPA staff and its
agents. A procedural manual, EPA Information Security Manual.
explains how to comply with this policy and with the congression-
ally-mandated Computer Security Act of 1987. The following
Discussion summarizes the detailed information contained in these
documents.
Security of LIMS is often an afterthought that LIMS staff and users
frequently minimize as an unnecessary imposition, or view as
preventing free information exchange, rather than as safeguards for
the destructive effects of malicious hackers, LIMS failures or natural
disasters. Congress emphasized the importance of security by
enacting the Computer Security Act of 1987. Experienced LIMS
staff and users are becoming acutely aware of the need for safe-

8.6 Security
guards to protect against undesired and frequently unforeseen events. These events,
whether accidental or deliberate, can result in:
modification or destruction of data,
unavailability of data or services, or
the unwanted disclosure of data.
These three general damaging results have shaped the three traditional objectives
(see I, Security Objectives below) of computer security:
integrity,
availability, and
confidentiality.
They commonly form the basis for all security decisions or initiatives.
Undesired events, commonly referred to as threats (see III. Threats), should be
identified for all the assets constituting the LIMS. These assets (see II, Assets) can
include people, hardware, software, physical environment, and others. Reaching
a decision about what, if anything, should be done for each identified threat/asset
involves two distinct phases:
risk analysis (see IV. Risk AnaljsK), identifying and estimating the
damage of each threat/asset risk; and,
risk management (see V. Risk Management), identifying, selecting, and
implementing safeguards to protect against the threat, reduce its impact, or
facilitate recovery from its occurrence.
There are some minimum safeguards (see \'L Minimum Safeguards) that com-
mon sense dictates be implemented to ensure physical protection of LIMS hard-
ware, software, data, and storage media. The cost involved with implementing
these safeguards may be very small, if not zero, and thus do not require a formal
security risk analysis to justify their implementation.
Good Automated Laboratory Practices 2-79

-------
8.6 Security, continued
I. Security Objectives
The integrity objective provides owners and users of laboratory data with
assurance that their data are reliable and accurate. Achieving this objective
necessitates implementation of safeguards for threats to the integrity of data and the
applications that process the data. Examples of safeguards for software that
provide assurance of integrity include implementing data verification procedures
formanual data entry as specified in 8.4.4, implementing data change requirements
described in 8.4.5, and password-protecting access to LIMS software (see VI.
Minimum Safeguards).
The availability objective provides protection against the loss of information or
services. Serious problems can result from loss of LIMS data because they can be
costly to replace. Similarly, if the LIMS cannot be used or cannot provide timely
services, the production or reporting of LIMS data can be lost or impaired.
Examples of safeguards to provide assurance of the availability of LIMS data
include implementing a regular schedule for backups, placing storage media in a
secured place, and use of an Uninterruptible Power Supply device to provide
virtually complete surge protection, a filter for line noise, and backup power in the
event of an outage (see VI. .Minimum Safeguards).
The confidentiality objective addresses those situations where disclosure of data
would be undesirable or, in some situations unlawful, such as Confidential
Business Information (CBI) (see Notes at end of Discussion for references).
Confidentiality ensures the protection of private information from being disclosed
to anyone who is not authorized to access it. Examples of safeguards to provide
assurance of confidentiality include physical access controls, encryption when
transmitting data, and disposal practices for reports when they are no longer needed
(see VI. Minimum Safeguards).

2185 1995 Ed 8/10/95
-------
8.6 Security, continued
II. Assets
An asset has value and may be tangible or intangible. An organization should
identify all assets that must be protected. Some assets have minimal value and do
not require protection. A partial list of potential assets includes the following:
Tangibles Intangibles
Facilities Personnel
Hardware Reputation
Software (system and application) Motivation
Supplies Morale
Documentation Goodwill
Data Opportunity
Traditionally, tangible assets were viewed as only hardware and were the major
concern of security. Placing a value on these assets may be relatively easy because
in most cases they are purchased items.
However, tangible assets also include software, data, and documentation. It can be
difficultto place a value on data and documentation because these assets are usually
derived from expenditures of a variety of laboratory resources. LIMS data are
obtained from sources such as observations, analytical instruments, and laboratory
equipment. If data are the result of an analytical experiment or sample analysis,
value can be derived from examining the resources used during the process that
produced them.
Another consideration in determining the value of LIMS data is the capability of
reproducing the dataitself. Data that cannot be reproduced may have a significantly
higher value than data that are easily reproduced. In a similar manner, the value of
the documentation for the LIMS and its applications must be determined.
The value of intangible assets is somewhat subjective. However, intangible assets
must be identified and considered when performing a security risk analysis.

8.6 Security, continued
III. Threats
Once LIMS assets are determined, it is necessary to identify threats, potential
threats, and future threats to the assets. By identifying these threats, possible
vulnerabilities to integrity, confidentiality, and availability can be identified and
addressed. Threats may exist in many forms; they can be the result of natural
disasters, intentional or accidental action, or malicious or inadvertent destruction.
Natural disasters and environmental hazards are significant threats primarily to
LIMS tangible assets. Potential natural disaster can include floods, tornadoes, or
hurricanes. Environmental hazards include fires, water damage (from bursting
water pipes), and power failures. These disasters can damage or completely destroy
the facility, operating environment, documentation, hardware, software, and LIMS
data. Disruption can occur to communication, operations, or applications.
Other significant threats can result from unrestricted access to the LIMS assets.
Safeguards are most often needed that limit access to the facility, equipment,
hardware, software, documentation, and data. Threats must be assessed for every
potential avenue of access. LIMS data are especially vulnerable because they are
subject to accidental modification or destruction as well as malicious acts of theft
or data sabotage. Accidental data corruption can result from faulty procedures or
from failures of system software security. Training of personnel and development
and compliance with comprehensive SOPs can eliminate much accidental data
corruption or loss.
The threat of computer fraud, frequently motivated by greed and malice, should be
considered. The greater the LIMS data value the greater the potential for intentional
threats. LIMS data should be reviewed to determine if there is value or liability
from an intruder in penetrating the LIMS, disclosing its data, or disrupting
operations. Similarly, the LIMS data should also be evaluated to determine the
impact of decision making and reporting based on incorrect or corrupted data. In
addition to physical controls, the development of and compliance with comprehen-
sive SOPs provides safeguards against theft or sabotage.

IV. Risk Analysis
Risk analysis is a process for estimating potential losses that may result from LIMS
vulnerabilities and quantifying the damage that may result if adverse events occur.
The ultimate goal of risk analysis is to select safeguards that reduce risks to an
acceptable level. Risk analysis is a means of determining the resources needed
in budgetary terms of programming, equipment and people to minimize the loss
of LIMS data integrity, availability, or confidentiality. The extent of the risk
analysis depends on the complexity of the LIMS system, its uses, the characteristics
of its users, and the value of the LIMS data.
EPA Information Security Manual describes methods for performing risk analyses
for different types of LIMS assets.
Step 1 Identification of assets and determination of threats;
Step 2 Identification of existing safeguards;
Step 3 Determining the overall risk to the system based on threats identi-
fied and effectiveness of existing safeguards;
Step 4 Evaluation and selection of safeguards; and
Step 5 Preparing a summary of findings and recommendations.
This risk analysis can then be used as the basis for establishing a cost-effective risk
management program.

8.6 Security, continued
V. Risk Management
Risk management ensures that adequate steps are taken to prevent or mediate
situations that can interfere with accomplishing the laboratory's mission. Risk
management includes establishing security safeguards and plans for contingencies
(disaster recovery plans). A necessary part of risk management is to assure
implementation of the safeguards and contingency plans. An important first step
is to provide proper training of personnel (security awareness training) to ensure
that all employees understand their security roles.
Risk management involves establishing safeguards to improve protection of
information and information processing resources and to adequately protect the
LIMS data from loss, misuse, unauthorized access or modification, unavailability,
or undetected activities. Safeguards may include restricted user interfaces to LIMS
system and application software and LIMS data, user verification, isolation of
critical LIMS application software, and reviewing and testing the LIMS design.
Including safeguards from the start of LIMS development or LIMS procurement
effort is the most cost-effective way to optimize integrity, availability, and
confidentiality of LIMS data. Risk analysis information, described above, should
be used in the design phase of LIMS development to effect the greatest reduction
in the annual loss expectancy at the least total cost. This information can also guide
laboratory management in developing procedures to meet the LIMS security
objectives of integrity, availability, and confidentiality. To maintain LIMS
security, audits of security practices assist laboratory management in monitoring
security needs and in maintaining reliable compliance with established safeguards.
Another aspect of risk management involves the development of contingency plans
(or disaster recovery plans) for LIMS operations in the event of a failure or
emergency from a number of potential sources such as natural disasters or
equipment malfunction. Laboratory management should develop workable proce-
dures that ensure the continuance of essential functions in the event that LIMS
functions are interrupted. The primary objective of contingency planning is to
protect against unacceptable data loss. It is also important to provide protection
for source documents, input and output data, and application software. It may also
2-84 Good Automated Laboratory Practices
Implementation Assistance

-------
8.6 Security, continued
V. Risk Management
be necessary to anticipate the need for alternate hardware and equipment. Contin-
gency plans should include procedures for remote storage of backup data and
recovery of data from backup data files. Contingency planning should be
coordinated with other hardware safeguards, backup procedures, and recovery
plans.
Security awareness training is an important first step in implementing any risk
management plan. All employees involved in the management, use, design,
development, maintenance, or operation of the LIMS should be aware of their
security responsibilities. Laboratory management should select and implement
appropriate security awareness techniques such as training, lectures and seminars,
posters, and orientation booklets. Incentives for adherence by staff to security
procedures may include assigning employee responsibility for security, publicity
of security breaches, and rewards for employees who prevent breaches.
Specific requirements for security and disaster recovery plans are found in EPA
Information Security Manual and EPA Operations and Maintenance Manual.

VI. Minimum Safeguards by Asset:
Stand-alone, Networked, and Data Center Computing
Meeting the objectives of data integrity, availability, and confidentiality necessi-
tates that certain minimum safeguards be implemented for the LIMS. Minimum
safeguards are those common sense measures which may be implemented without
performing a risk analysis. These safeguards ensure the physical and environmen-
tal protection of LIMS equipment and media, and the effective management of the
LIMS.
The cost involved in implementing these safeguards should be minimal. If the
LIMS contains sensitive information, OMB Bulletin No. 90-08, Guidance for
Preparation of Security Plans for Federal Computer Systems that Contain
Sensitive Information, (July 9, 1990) applies. (Data are considered sensitive if
they meet the criteria established in Federal statutes (see Notes at end of
Discussion) and/or are defined as sensitive through risk analysis. Sensitive data
also is defined by legal agreement protecting information such as site location or
source information.)
This section describes minimum safeguards by LIMS asset, arranged into three
categories:
A. Stand-alone Computing
0 Networked Computing
C. Data Center Computing
"Stand-alone computing" is defined as those LIMS that have no physical or logical
connection to any other computer system. A logical connection is an active
network connection; it is a connection to another computer. A physical connection
is a communication connection (wire or optic cable) to another computer or
network. Generally, stand-alone computers are those personal computers or
workstations that have no connection whatsoever (physical) to a network or to
another computer. However, a computer could be considered a stand-alone
system if it is physically connected to a network or another computer, but does not

have the ability to transmit to or receive data from the network or system. Examples
include:
a computer with no physical connection to another computer
a computer with a physical connection, but the installed networking
software is disabled or is inactive
"Networked computing" is defined as those LIMS that have an active logical
connection to a network or to another computer system. In practice, most
networked computers are personal computers, workstations, or minicomputers that
have active connections to a local area network (LAN) or wide area network
(WAN). Many of these systems are increasingly participating in client/server
relationships that share the workload over several computers. The maj ority of these
computer systems are usually physically located on or near an employee's work
space.
"Data center computing" is defined as those LIMS that are physically located
within the confines of a special facility dedicated to computing. Data center
computers are almost always large minicomputers and mainframes with special-
ized peripherals such as external disk arrays, tape drives, and telecommunications
interfaces. Certain security issues, mostly those involving special physical and
environmental safeguards, apply to data center computers.
Some LIMS computing environments do not fall neatly into one of these categories.
For example, most data center computers have active connections to a network.
With the rapidly evolving sophistication of networking software, it is conceivable
that a stand-alone computer can have small networking modules activated that
permit trivial, but highly secure, networking operations to take place. When the
system's computing configuration or environment appears to overlap a category,
the more stringent safeguard should be applied.

Stand-alone LIMS are sometimes considered the least susceptible to the
viruses and hacking that have become a threat to networked systems.
However, the data integrity and availability of stand-alone systems can be
easily compromised if the physical and environmental safeguards specified
below are not followed. Data integrity and availability are improved by
adherence safeguards for the storage and use of magnetic media and
backups. Assurance of integrity can also be improved by carefully avoiding
situations that may subject the stand-alone system to viruses borne by
removable media such as diskettes. Software copyrights and licensing are
a factor that may affect data availability. Data confidentiality can be
compromised if stand-alone systems are easily accessible to unauthorized
personnel. Data confidentiality of stand-alone systems is best improved by
defining, training for, and adhering to, individual safeguard responsibilities.
2. Security Responsibility Training;
At least one person, or functional group, should be assigned the overall
responsibility for maintaining stand-alone LIMS security. The responsible
person or group should have the authority and opportunity to contribute to
policy decisions regarding the security topics discussed within this section
(physical and environmental, magnetic media safeguards, backups, etc.).
All LIMS users should be provided with security awareness training.

locate equipment away from easily accessible areas and install a locking
device (pad or hardened cables) to the extent possible. Use a standard keyed
system cabinet lock. Place equipment and peripherals on stable and secure
platforms away from objects that could fall on them.
Store all portable LIMS in a locked cabinet when not in use. Ensure that at
least one individual within the organization is responsible for tracking the
location of portables on a regular basis, and institute logging procedures that
include the release and return dates for authorized users.
Install surge protection devices to protect against electrical power surges.
Do not install the electronic equipment, especially personal computers, in
direct sunlight or in a location with extremes of hot and cold temperatures
(less than 50 degrees Fahrenheit or greater than 100 degrees Fahrenheit). Do
not leave a portable in a parked car, which would also subj ect it to temperature
extremes.
Do not eat, drink, or smoke in the immediate vicinity of LIMS equipment and
media. Install, as far as practical, away from overhead water pipes or
sprinkler heads. Install and use humidifiers when the ambient air is
extremely dry.

Keep all magnetic media in a secure area away from electrical devices and,
especially, magnets. Magnets can be found in magnetic paper clip holders,
building passes and credit cards with magnetized strips, PC hard drive units,
speakers, and telephones. Do not flex diskettes, touch their surfaces, or write
on them directly with a pencil or hard-tipped pen. Store them in disk file
containers as soon as they are removed from equipment. Store cartridge
tapes and removable disk cartridges in their original containers. Backup all
files on a fixed disk at regular intervals.

Routine backup procedures should be established to ensure availability of the
LIMS data Stand-alone personal computers are often the least likely to be
backed up. While a precise set of criteria for determining how often to make
these backups cannot be provided, frequency of modifications to data files,
cumulative development time, and the relative importance of the data are key
factors to consider. Many organizations perform backups at least once a
week.
The appropriate backup media can vary and may include diskettes, cartridge
tapes, removable disk cartridges, or remote hosts such as minicomputers.
In all cases, the resultant backup media should be tested at a frequency
adequate to ensure that backup procedures are working correctly. More than
one person within an organization should have the knowledge required to
perform backups to avoid backup schedule interruptions due to personal
leave or termination.
6, Software Copvrights anil License's
Commercial software is frequently subject to copyright laws and accompa-
nied by a licensing agreement that specifies copying regulations. A
copyright generally means that any duplicating, selling, or other distribution
of the software for other than backup use by the lawful user(s) is unlawful.
Many of these copyrighted software packages may affect data availability.
Some software applications cease to function upon expiration of the license;
previous data access provided by the software may be lost. Licenses are
usually available for single systems or for entire sites. LIMS management
should be vigilant to eliminate unlicensed software and maintain current
licenses for stand-alone personal computers. Supervisory personnel should
educate LIMS users on the importance of adhering to copyright law.

Registering all copies of commercial software with the vendor can result in
significant cost savings in free user assistance, reduced price software
upgrades, or free replacement if the software is lost, stolen, or damaged.
", Viruses
A computer virus is an extra program hidden within an apparently normal
program or software package. The normal program or software is referred
to as the virus "host" or "Trojan Horse." Some viruses are relatively
harmless and only flash a message on the monitor before destroying
themselves. Others are truly malicious and modify or destroy programs and
data. One means to avoid viruses on stand-alone LIMS is to purchase only
commercially-produced software (although commercial software is not
immune to viruses, either), and to run a virus scanning program on every
diskette before reading the diskette or copying files from it. To combat
viruses, anumber of specialized programs or software "vaccines" have been
developed. Some are available at low cost, or through the operating system
vendor. New software should also be tested for viruses on stand-alone
computers. A relevant publication, NIST Special Publication 500-166,
Computer Viruses and Related Threats: A Management Guide (August
1989), should be consulted.
B. Networked Computing
Networked computing is highly vulnerable to security threats, because of
its use by large numbers of individuals throughout an organization or, in the
case of the Internet, the world. Due to their predominance on WANs such
as the Internet, workstations, minicomputers, and even mainframes histori-
cally were the prime targets of viruses and hackers. The lack of security and

auditing software available for personal computer operating systems makes
these systems singularly ill-equipped to deal with sophisticated threats that
can exist on local or wide-area networks.
Networked LIMS computing is subj ect to the same physical and environmen-
tal threats as stand-alone or data center LIMS computing. Data integrity,
availability, and confidentiality of networked systems may be compromised
if the physical and environmental safeguards specified below are not fol-
lowed. Data integrity, availability, and confidentiality can be improved by
adherence to safeguards regarding the treatment of magnetic media, backups,
and by implementing safeguards to protect against viruses borne by a local or
wide-area network.
Networked computing should implement the minimum operating system and
application safeguards described below. Networked personal computers,
workstations, file servers, print servers, database servers, and minicomputers
that operate outside the confines of a data center should adhere to the
minimum safeguards described in A. Stand-alone Computing. Networked
data center computers should adhere to the operating system and application
safeguards (below) in addition to the safeguards described in . Data Center
Computing.
2. System Application
irilr Safegua
Minimum application security safeguards are implemented largely accord-
ing to the sensitivity of data stored within a LIMS system. The presence of
sensitive data on a LIMS necessitates more stringent measures than those
described below. For LIMS that process sensitive data on a multi-user
system, laboratory management should research the cited references (see
Notes at end of Discussion) for details regarding application security
safeguards for sensitive data. Safeguards can be applied to the operating

system, commercial and internally developed software programs running on
the multi-user system, and data stored on the system.
Minimum operating system safeguards on a networked LIMS include:
implementation of individual username and password management pro-
grams
file access safeguards maintained by the data or file owner
assignment of operating system privileges only to systems management
personnel
monitoring of system events such as logon failures or break-in attempts
emergency, backup, disaster recovery, and contingency plans
application-specific safeguards
Usernames should be assigned and maintained by the individual or group
responsible for maintaining the LIMS. Usernames should be provided only
to individuals, whenever possible. If group IDs are necessary, they should be
assigned limited privileges and revoked as soon as feasible.
Password maintenance is ultimately the responsibility of the individual LIMS
user, but basic syntax rules are necessary, especially where the LIMS is
susceptible to password cracking schemes used by hackers through dial-up
modems, LANs, or WANs. Passwords should be:
1) a minimum of six characters in length,
2) consist of numerals and alphabetic characters,
3) changed at least once every 90 days, and
4) should avoid common names, words found in a dictionary, or repetitive
character sequences.
File access safeguards should be implemented to restrict the use of LIMS
data to only users with authorized access. Group or public file access should

be discouraged. Assigning write or delete privileges to increasing numbers
of LIMS users effectively cancels several safeguards because of the increased
opportunity to modify the LIMS data.
Operating system privileges should be assigned very sparingly, and only to
those individuals working directly with the operating systems. Assigning
system privileges to the general user population causes a wide array of
security problems.
Whenever possible, a system for monitoring events such as logon failures or
break-in attempts should be implemented. After three failed logon attempts,
the account should be automatically disabled. Event logs should be reviewed
on a frequent, and regular, basis. Most minicomputer and mainframe
operating systems provide system event logging at no extra cost.
System and data backups (see C.4 Data Center Backups) are the keystone
of emergency, backup, disaster recovery, and contingency plans. A well
thought-out and tested plan is a significant safeguard against unforeseen
natural or man-made disasters. The plan includes notification procedures,
recovery operations, LIMS interim processing, and restoration planning.
Application-specific safeguards include the use of application-specific
usernames and passwords. The commercial database market includes nu-
merous database products that provide additional internal security safe-
guards, including application-specific usernames and passwords. Most of
these also have complex security protection schemes that grant and revoke
database privileges, read/write access, and group protections. In many ways,
these application protections are as sophisticated as their operating system
counterparts, and should be used to augment operating system safeguards.

C. Data Center Computing
Because data centers usually involve large, centralized LIMS, such as
mainframe computers, that also participate in local and wide area networks,
the security measures that apply to networked LIMS should apply to data
center computers. Security training of all data center computer users is
essential for maintaining data integrity, availability, and confidentiality.
Security awareness is important because enormous amounts of potentially
sensitive information are concentrated in one area and, frequently, among a
small number of large computer systems. Data availability can be compro-
mised by failure to adhere to physical and environmental safeguards. Data
integrity and availability are improved by backup and change control prac-
tices.
At least one person, or functional group, should be assigned the overall
responsibility for maintaining LIMS security. A responsible person (see
8.1,6) or group should have the authority and opportunity to contribute to
policy decisions regarding the security topics discussed within this section
(physical and environmental, safeguards, backups, etc.). All LIMS data
center users should be provided with security' awareness training. Because
most data centers include a complex local area network, and involve interac-
tive logons, users should be provided with training in password maintenance
and file protections.

J« Physical and Environmental Safeguards
LIMS data center management should strive to locate the data center away
from the ground floor, frequently traveled or easily accessible areas, and
potential sources of explosions (e.g., boiler rooms, hot water heaters). When
choosing a site, take advantage of existing physical security. Limit the
number of doors and entrances to those needed for safe and efficient
operations. Install and use locks on all windows and doors.
When possible, locate master power switches near emergency exits. The
switch should cut off all power to the LIMS and, if possible, should also turn
off the air conditioning system if it is not designed to filter out smoke.
Use fire extinguishers designed to avoid damage to computer equipment, and
mount them in visible, accessible areas. Install smoke and heat detectors.
Avoid installing the computer room underneath water pipes or steam pipes.
If this is not possible, use water sensors to detect water seepage. If practical,
store waterproof plastic in a visible, accessible location so that it can be
draped over equipment in an emergency.
Prohibit eating, drinking, and smoking in the computer room. To reduce dust,
avoid coat racks, throw rugs, Venetian blinds, and other furnishings that
collect dust and static electricity. Vacuum carpeted areas frequently. Control
static electrical charges by using anti-static carpeting or sprays. To reduce fire
hazards, never store flammable materials in the computer room. Keep on-site
paper supplies to a minimum.

Backups are a key element in disaster recovery plans, and should occur on a
regular and published schedule. The resultant backup media and recover}'
procedures should be tested frequently to ensure that backup procedures are
working correctly. The appropriate backup media can vary and can include
diskettes, cartridge tapes, removable disk cartridges, or remote hosts such as
minicomputers. LAN server backups should occur on aregular and published
schedule. More than one person within an organization should have the
knowledge required to perform backups to avoid backup schedule interrup-
tions due to personal leave or termination.
Threats to integrity, availability, and confidentiality are introduced through
unauthorized change to hardware or software. To help achieve effective
change control, laboratory7 management shall maintain accurate records of
hardware and software inventories, configurations, and locations (see 8.5,4
and 8.7.2); and shall comply with the terms of software licensing agreements.
Prescribe a standardized, formalized method of introducing changes to both
software and hardware (see 8.5,1 .3 and &,1.2). To ensure data availability,
prepare a contingency plan, or other procedure to revert to a previous version
of the software, in the event that the change does not work as intended.

Proper performance of the LIMS hardware and communications
components is often dependent on the capacity of the system and the
appropriate configuration of the components. Periodic review of
LIMS design may be valuable in assessing the need for modifica-
tions to improve productivity, reduce risk of malfunction, and
improve LRD integrity, availability, and confidentiality (see 8.6

operation of the LIMS. The maintenance program and procedures
should be determined by the vulnerability of the LIMS.
All maintenance specified in the SOPs, whether performed by in-
house personnel or outside contractors, should be included in the
documentation. The operations maintenance documentation should
be kept with the hardware and communications components for
ready access.
A "repair log" may be used to document non-routine maintenance
performed on the LIMS. It should be easily accessible to the LIMS
personnel responsible for updating the log and to the personnel using
the LIMS hardware and communications components. This docu-
mentation should be retained for as long as needed to support
evidence of LRD integrity, or longer if required by other regulations
(see S.9), and should be reviewed on a regular basis by LIMS
management. When repairs are performed by the manufacturer's
service representative or other outside personnel, a written report is
usually provided. This report can be helpful to document the
problem and should be retained. Centralized responsibility for
contacting outside service support and maintaining the documenta-

SPECIAL
CONSIDERATIONS
In order to ensure ongoing LIMS reliability, performance, and
accuracy, comprehensive testing of the LIMS shall be conducted at
least once every 24 months.
This testing should also include a complete document review (SOPs;
change, security, and training documentation; error logs; problem
reports; disaster plans, etc.). Laboratories that change LIMS soft-
ware or hardware within the 24-month interval shall conduct accep-
tance testing as required by 8.5.2 and 8.7.2.
A comprehensive testing team can be assembled that may include
LIMS users, support personnel, and laboratory management, so that
the interests and skills of these individuals can be addressed in the
testing process. A test data set can be developed that significantly
exercises all important functions of the system. This test data set can
then be retained and re-used for future system tests. It may have to
be enhanced if new functionality is added to the system. System test
protocols and test objectives can be developed and re-used. A
checklist can be developed to ensure that all important areas of
testing and document review are addressed.
Consultation with QAU personnel during comprehensive testing
may be advantageous. However, QAU's independence from LIMS
staff must be maintained (see 8.3.1).

8.10 Facilities
1) Environment
When LIMS Raw Data are collected, analyzed, processed, or maintained, laboratory
management shall ensure that:
1) the environmental conditions of the facility housing the LIMS are regulated to
protect against LIMS Raw Data loss.
EXPLANATION
DISCUSSION
The LIMS shall be housed in an environment that allows it to
operate correctly. Control systems should be applied to all environ-
mental factors that might affect LRD loss or integrity. At a
minimum, LIMS hardware should be installed in accordance with
the environmental standards specified by the manufacturer. Con-
trol systems (see 8.6 Minimum Safeguards Discussion) should
ensure:
proper temperature and humidity
freedom from dust and debris
adequate power supply and grounding
protection from power surges and spikes
fire detection and suppression
water detection and suppression
protection from natural disasters
The provisions to regulate environmental conditions are discussed
in greater detail in 8.6 Minimum Safeguards by Asset. The
provisions are summarized here to emphasize their importance.
Climate control systems
LIMS hardware should be installed according to manufacturer's
climate specifications. Heating, ventilation, and air conditioning
dedicated to the computer room or other location where hardware is
installed should be considered. Monitoring or control devices for
temperature and humidity are usually installed. Backup climate
control systems may be worthwhile if time is critical.

1) Environment
Power provision
Power supplies should comply with the computer hardware manu-
facturer specifications. It may be appropriate to install backup
power supply systems where electrical outage would cause critical
loss or where electrical outage frequently occurs.
Fire and water control systems
Detection and suppression devices for fire and water should be
considered. A sprinkler system may be suitable for some facilities,
but a CO2 system may be suitable for others.
Protection against natural disasters
The facility should be designed and protected according to geo-
graphic conditions. Where earthquakes are likely, housing should
be examined for potential destruction of the LIMS and its data.
Where tornadoes are likely, consideration should be given to
locating computer equipment on lower levels of the facility. Where
flooding is likely, consideration should be given to locating com-
puter equipment on upper levels of the facility.
Operating procedures
Routing procedures for checking and maintaining detection and
suppression devices will ensure that devices are in working order.
Additional procedures may be established that describe how to
operate the LIMS during emergency situations (for example, pow-
ering down).

2) LIMS Raw Data Storage
When LIMS Raw Data are collected, analyzed, processed, or maintained, laboratory
management shall ensure that:
2) environmentally adequate storage capability for retention of LIMS Raw Data,
LIMS Raw Data storage media, documentation, and records
pertaining to the LIMS are provided.
EXPLANATION
DISCUSSION
Environmentally satisfactory and adequate storage space shall be
available for LRD, LRD storage media, and documentation and
records (which may be retained in hard copy format or on magnetic
or optical media).
Operations personnel should maintain an adequate supply of re-
quired tapes, magnetic disks, and/or optical disks and ensure that
storage space is sufficient to meet current and anticipated needs.
Storage facilities for retention of LRD in hard copy or electronic
format must be available and environmentally satisfactory for the
LRD storage media. At a minimum, the storage facility should have
a heating, ventilation, and air conditioning system to control tem-
perature and humidity that will meet the storage condition specifi-
cations of the specific media.
Offsite storage is recommended for backups. Backups can be cycled
through the offsite location. For example, the most recent backup
may be kept on the premises while the previous backup is kept
offsite. This procedure retains the most recent version onsite for
convenience while securing another version offsite for use in the
event of disaster. Offsite storage facilities must have the same
environmental control and security systems required of onsite
storage facilities. In addition, fire and water control systems and
protection against natural disasters should be considered as dis-
cussed in 8.10.1.

previous version shall be removed from the work area and retired
according to 8.11.4. If multiple staff perform the same procedure in
different locations, copies of SOPs shall be available in each loca-
tion. When LIMS staff changes occur, the replacement staff shall be
provided with the SOPs.
If multiple copies of SOPs exist, then maintaining the originals in a
secure location is recommended (see also 8,11.4). Laboratory
management should ensure that all copies of SOPs are kept current
and that copies of retired versions of SOPs are removed from
circulation.

2) Periodic Review
Laboratory management shall ensure that:
2) SOPs are periodically reviewed at a frequency adequate to ensure that
they accurately describe the current procedures.
EXPLANATION
DISCUSSION
SPECIAL
CONSIDERATIONS
It is laboratory management's responsibility to establish and ensure
that current SOPs accurately document current LIMS activities.
Laboratory management shall ensure that SOPs are reviewed at a
frequency adequate to assure the integrity of LIMS Raw Data.
The adequacy of SOPs is laboratory management's responsibility;
therefore, direct and frequent communication with LIMS staff is
implied. The QAU can assist laboratory management in assuring
that the SOPs are current by reporting any differences between an
SOP and the corresponding LIMS activity. Inspections, and SOP
review can be used by the QAU for this purpose (see 8.3.3 and
83.4).
Changes in critical LIMS support staff or major LIMS hardware
and software changes are important milestones for the QAU or
laboratory management to review the accuracy of SOPs with
respect to LIMS activities.

3) Authorization and Change
Laboratory management shall ensure that:
3) SOPs are authorized and changed in accordance with 8.1.5.
EXPLANATION
DISCUSSION
SOPs set forth and document the methods that assure laboratory
management of the integrity of LIMS Raw Data. Thus, laboratory
management shall authorize each SOP and any subsequent changes
to the SOP. The previous version or copy of the SOP shall be
retained according to 8.11.4.
Authorization of SOPs and all changes to SOPs by laboratory
management ensures that procedures are consistent with all labora-
tory policies and requirements. It allows management to exercise
control of the activities of the laboratory operations. This also
communicates to the LIMS staff the importance of compliance with
the approved SOPs. See 8.1.5 for further discussion.

4) Historical File
Laboratory management shall ensure that:
4) a historical file of SOPs is maintained.
EXPLANATION
DISCUSSION
SPECIAL
CONSIDERATIONS
All versions of SOPs, including retired SOPs, shall be maintained in
historical files. The effective dates of each SOP shall be indicated.
Retired SOPs shall be retained in accordance with 8.9.
A centralized historical file or files of SOPs may be an advantage
because of the assurance that the file is properly maintained and
effectively managed. However, larger LIMS operations may appro-
priately maintain separate historical files of SOPs critical to LIMS
Raw Data integrity. Depending on the LIMS operations, multiple
historical files may be preferable over a single file for all SOPs.
Historical files of SOPs may be stored on magnetic media. How-
ever, storage conditions must be consistent with 8,10.2 so that the
SOPs remain available over time.
