Vapors may cause dizziness or asphyxiation without warning.
Vapors from liquefied gas are initially heavier than air and spread along ground.
FIRE OR EXPLOSION
Non-flammable gases.
Containers may explode when heated.
Ruptured cylinders may rocket.
PUBLIC SAFETY
CALL Emergency Response Telephone Number on Shipping Paper first. If Shipping Paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.
As an immediate precautionary measure, isolate spill or leak area for at least 100 meters (330 feet) in all directions.
Keep unauthorized personnel away.
Stay upwind, uphill and/or upstream.
Many gases are heavier than air and will spread along ground and collect in low or confined areas (sewers, basements, tanks).
Structural firefighters' protective clothing will only provide limited protection.
EVACUATION Large Spill
Consider initial downwind evacuation for at least 100 meters (330 feet).
Fire
If tank, rail car or tank truck 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
FIRE
Use extinguishing agent suitable for type of surrounding fire.
Move containers from fire area if you can do it without risk.
Damaged cylinders should be handled only by specialists.
Fire involving Tanks
Fight fire from maximum distance or use unmanned hose holders or monitor nozzles.
Cool containers with flooding quantities of water until well after fire is out.
Do not direct water at source of leak or safety devices; icing may occur.
Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank.
ALWAYS stay away from tanks engulfed in fire.
SPILL OR LEAK
Do not touch or walk through spilled material.
Stop leak if you can do it without risk.
Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material.
Do not direct water at spill or source of leak.
If possible, turn leaking containers so that gas escapes rather than liquid.
Prevent entry into waterways, sewers, basements or confined areas.
Allow substance to evaporate.
Ventilate the area.
FIRST AID
Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves.
Move victim to fresh air.
Call 911 or emergency medical service.
Give artificial respiration if victim is not breathing.
