POTENTIAL HAZARDS |
|
| - Some may burn but none ignite readily. |
| - Containers may explode when heated. |
| - Ruptured cylinders may rocket. |
| CAUTION: Aerosols (UN1950) may contain a flammable propellant. |
|
|
| - Vapors may cause dizziness or asphyxiation without warning. |
| - Vapors from liquefied gas are initially heavier than air and spread along ground. |
| - Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. |
| - Fire may produce irritating, corrosive and/or toxic gases. |
|
|
PUBLIC SAFETY |
| - 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. |
| - Keep unauthorized personnel away. |
| - Stay upwind, uphill and/or upstream. |
| - Many gases are heavier than air and will spread along the ground and collect in low or confined areas (sewers, basements, tanks, etc.). |
| - Ventilate closed spaces before entering, but only if properly trained and equipped. |
|
|
| - 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. |
|
|
| Immediate precautionary measure |
| - Isolate spill or leak area for at least 100 meters (330 feet) in all directions. |
| Large Spill |
| - Consider initial downwind evacuation for at least 500 meters (1/3 mile). |
| 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 |
|
| - Use extinguishing agent suitable for type of surrounding fire. |
| Small Fire |
| - Dry chemical or CO2. |
| Large Fire |
| - Water spray, fog or regular foam. |
| - If it can be done safely, move undamaged containers away from the area around the fire. |
| - Damaged cylinders should be handled only by specialists. |
| Fire Involving Tanks |
| - Fight fire from maximum distance or use unmanned master stream devices 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. |
| - Some of these materials, if spilled, may evaporate leaving a flammable residue. |
|
|
| - Do not touch or walk through spilled material. |
| - Stop leak if you can do it without risk. |
| - Do not direct water at spill or source of leak. |
| - Use water spray to reduce vapors or divert vapor cloud drift. Avoid allowing water runoff to contact spilled material. |
| - 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. |
|
|
| - Call 911 or emergency medical service. |
| - Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. |
| - Move victim to fresh air if it can be done safely. |
| - 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 liquefied gas, thaw frosted parts with lukewarm water. |
| - Keep victim calm and warm. |
