6. ACCIDENTAL RELEASE MEASURES
Spill Response Notice:
Only persons properly qualified to respond to an emergency involving hazardous substances should respond to a spill
involving chemicals. See Section 13, Special Instructions for disposal assistance.
Containment Technique: Releases of this material may contaminate the environment. Stop spilled material from being
released to the environment. Absorb spilled liquid with non-reactive sorbent material. Dike the spill to contain material for
later disposal.
Clean-up Technique: Mercury and its compounds are extremely toxic! Be extremely careful not to contact the spill or
breathe any vapors. Absorb spilled liquid with non-reactive sorbent material. Dispose of all mercury contaminated
material at an E.P.A. hazardous waste facility. Dispose of material in an E.P.A. approved hazardous waste facility.
Decontaminate area with commercially available mercury absorbing compounds.
Evacuation Procedure: Evacuate general area (50 foot radius or as directed by your facility's emergency response plan)
when: any quantity is spilled. Deny access to unnecessary and unprotected personnel. Remain up-wind from spilled
material. If conditions warrant, increase the size of the evacuation.
