It is recommended that a professional emergency response contractor clean up a mercury
spill. But if the spill is minor, school staff trained in hazardous materials spill cleanups can
take on the cleanup responsibilities.
Spiff Response Action Steps:
I. Evacuate the spill area. Leave all
shoes, clothing and other articles that
were splashed with mercury at the
spill area.
2. Wash skin exposed to mercury with
soap and water.
3. Immediately open the room's outside
windows and exterior doors to provide
ventilation.
4. Seal off the room from the rest of the
building by closing all interior doors
and windows. Close all cold-air
returns so that mercury vapor is not
carried throughout the school.
5. Lower the temperature of the room by
turning off the heat to the room. The
ventilation and cooling systems to the
spill area should be turned off. If
possible, all air ducts to the room
should be sealed temporarily.
6. Turn off fans unless they vent to the
outdoors. Use portable fans to blow
mercury-contaminated air outdoors.
7. If someone has inhaled mercury vapor
or ingested mercury, call a poison
control center (800) 222-1222.
8. Report the mercury spill to your state
environmental duty officer.
9. Hire a professional emergency
response contractor or make sure that
a trained staff person takes
responsibility for cleaning up the
mercury spill.
10. After cleanup is completed,
temporarily (for a few days) elevate
the room temperature to 80 to 90
degrees F. Continue to ventilate the
spill area for at least two days before
reoccupying it. Direct all ventilation
outside if possible.
11. Monitor the spill area to ensure that
mercury vapor levels meet the proper
Health Department criteria. This is
done with a mercury vapor analyzer or
collecting air samples for analysis at a
laboratory.
12. Properly recycle all mercury waste or
dispose of it as hazardous waste.
