Potential Hazards

Health

Inhalation of vapors or dust is extremely irritating.
May cause burning of eyes and lachrymation (flow of tears).
May cause coughing, difficult breathing and nausea.
Brief exposure effects last only a few minutes.
Exposure in an enclosed area may be very harmful.
Fire will produce irritating, corrosive and/or toxic gases.
Runoff from fire control or dilution water may cause environmental contamination.

Fire or explosion

Some of these materials may burn, but none ignite readily.
Containers may explode when heated.

Public Safety

General

CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.

Protective clothing

Wear positive pressure self-contained breathing apparatus (SCBA).
Wear chemical protective clothing that is specifically recommended by the manufacturer when there is NO RISK OF FIRE.
Structural firefighters' protective clothing provides thermal protection but only limited chemical protection.

Evacuation

Immediate precautionary measure
Isolate spill or leak area in all directions for at least 50 meters (150 feet) for liquids and at least 25 meters (75 feet) for solids.
Large Spill
Consider initial downwind evacuation for at least 100 meters (330 feet).
Fire
If tank, rail tank car or highway tank is involved in a fire, ISOLATE for 800 meters (1/2 mile) in all directions; also, consider initial evacuation for 800 meters (1/2 mile) in all directions.

Emergency Response

Small Fire

Dry chemical, CO2, water spray or regular foam.

Large Fire

Water spray, fog or regular foam.
If it can be done safely, move undamaged containers away from the area around the fire.
Dike runoff from fire control for later disposal.

Fire Involving Tanks, Rail Tank Cars or Highway Tanks

Fight fire from maximum distance or use unmanned master stream devices or monitor nozzles.
Do not get water inside containers.
Cool containers with flooding quantities of water until well after fire is out.
Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
ALWAYS stay away from tanks in direct contact with flames.
For massive fire, use unmanned master stream devices or monitor nozzles; if this is impossible, withdraw from area and let fire burn.

Spill or leak

Do not touch or walk through spilled material.
Stop leak if you can do it without risk.

Small Spill

Pick up with sand or other non-combustible absorbent material and place into containers for later disposal.
