Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite.
Odorless, will not be detected by sense of smell.
FIRE OR EXPLOSION
EXTREMELY FLAMMABLE.
May be ignited by heat, sparks or flames.
Flame may be invisible.
Containers may explode when heated.
Vapor explosion and poison hazard indoors, outdoors or in sewers.
Vapors from liquefied gas are initially heavier than air and spread along ground.
Vapors may travel to source of ignition and flash back.
Runoff may create fire or explosion hazard.
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).
Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection.
Structural firefighters' protective clothing provides limited protection in fire situations ONLY; it is not effective in spill situations where direct contact with the substance is possible.
Always wear thermal protective clothing when handling refrigerated/cryogenic liquids.
EVACUATION Spill
See Table 1 - Initial Isolation and Protective Action Distances.
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
DO NOT EXTINGUISH A LEAKING GAS FIRE UNLESS LEAK CAN BE STOPPED.
Small Fire
Dry chemical, CO2 or water spray.
Large Fire
Water spray, fog or regular foam.
Move containers from fire area if you can do it without risk.
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
ELIMINATE all ignition sources (no smoking, flares, sparks or flames in immediate area).
All equipment used when handling the product must be grounded.
Fully encapsulating, vapor-protective clothing should be worn for spills and leaks with no fire.
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.
Isolate area until gas has dispersed.
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.
Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes.
In case of contact with substance, immediately flush skin or eyes with running water for at least 20 minutes.
In case of contact with liquefied gas, thaw frosted parts with lukewarm water.
