5. Fire and Explosion Data
Fire and explosion
hazards:
Mercury presents a slight fire and explosion hazard when
exposed to heat or flame. Mercury vapors are heavier
than air and may travel a considerable distance to a
source of ignition and flash back.
Firefighting media:
Dry chemical, carbon dioxide, water spray or foam.
For larger fires, use water spray, fog or alcohol foam.
(1984 Emergency Response Guidebook, DOT P 5800.3).
Firefighting
procedures:
Use agents suitable for type of fire. Use water in flooding
amounts as a fog. Avoid breathing corrosive and
poisonous vapors. Keep upwind. Move containers from
the fire area if possible. Cool containers exposed to
flames with water from side until well after fire is out.
(1984 Emergency Response Guidebook, DOT P 5800.3).
6. Spill and Disposal Procedures
EPA Hazardous Waste Number: U151 (Toxic Waste)
If spilled or discharged:
Wear self-contained breathing apparatus and full
protective clothing. Clean up the spill immediately.
Collect and store using a suction pump with a capillary
tube. Calcium polysulfide with excess sulfur should be
sprinkled into cracks or inaccessible sites. Keep collected
mercury in a tightly closed bottle for recovery or disposal.
Disposal procedure:
Dispose in accordance with all applicable federal, state,
and local environmental regulations.
7. Storage and Handling Precautions
Mercury should be stored in a secure poison area inside a tightly closed container.
8. Exposure Control and Protective Equipment
Ventilation:
Use general or local exhaust ventilation to meet TLV
requirements.
Respiratory protection:
None required where appropriate ventilation conditions
exist. If the TLV is exceeded, a self-breathing apparatus
is advised.
Eye/skin protection:
Safety goggles and face shield, uniform, protective suit
and rubber gloves are recommended.
