Fire Fighting Procedures
If material on fire or involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible. Do not use water on material itself. Use water spray to knock-down vapors.
Evacuation: If fire becomes uncontrollable or containers is exposed to direct flame -- consider evacuation of one-half (1/2) mile radius.

DOT Emergency Guidelines
/GUIDE 120: GASES - INERT (INCLUDING REFRIGERATED LIQUIDS)/ Health: 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. /Trifluoromethane, refrigerated liquid/
/GUIDE 120: GASES - INERT (INCLUDING REFRIGERATED LIQUIDS)/ Fire or Explosion: Non-flammable gases. Containers may explode when heated. Ruptured cylinders may rocket. /Trifluoromethane, refrigerated liquid/
/GUIDE 120: GASES - INERT (INCLUDING REFRIGERATED LIQUIDS)/ Public Safety: CALL Emergency Response Telephone Number ... . 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. Many gases are heavier than air and will spread along ground and collect in low or confined areas (sewers, basements, tanks). Keep out of low areas. Ventilate closed spaces before entering. /Trifluoromethane, refrigerated liquid/
/GUIDE 120: GASES - INERT (INCLUDING REFRIGERATED LIQUIDS)/ Protective Clothing: Wear positive pressure self-contained breathing apparatus (SCBA). Structural firefighters' protective clothing will only provide limited protection. Always wear thermal protective clothing when handling refrigerated/cryogenic liquids or solids. /Trifluoromethane, refrigerated liquid/
/GUIDE 120: GASES - INERT (INCLUDING REFRIGERATED LIQUIDS)/ 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. /Trifluoromethane, refrigerated liquid/
/GUIDE 120: GASES - INERT (INCLUDING REFRIGERATED LIQUIDS)/ 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. /Trifluoromethane, refrigerated liquid/
/GUIDE 120: GASES - INERT (INCLUDING REFRIGERATED LIQUIDS)/ 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. CAUTION: When in contact with refrigerated/cryogenic liquids, many materials become brittle and are likely to break without warning. /Trifluoromethane, refrigerated liquid/
/GUIDE 120: GASES - INERT (INCLUDING REFRIGERATED LIQUIDS)/ First Aid: 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. Clothing frozen to the skin should be thawed before being removed. In case of contact with liquefied gas, thaw frosted parts with lukewarm water. Keep victim warm and quiet. Ensure that medical personnel are aware of the material(s) involved and take precautions to protect themselves. /Trifluoromethane, refrigerated liquid/
/GUIDE 126: GASES - COMPRESSED OR LIQUEFIED (INCLUDING REFRIGERANT GASES)/ Fire or Explosion: Some may burn, but none ignite readily. Containers may explode when heated. Ruptured cylinders may rocket.
/GUIDE 126: GASES - COMPRESSED OR LIQUEFIED (INCLUDING REFRIGERANT GASES)/ Health: 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.
/GUIDE 126: GASES - COMPRESSED OR LIQUEFIED (INCLUDING REFRIGERANT GASES)/ Public Safety: CALL Emergency Response Telephone Number ... .

/GUIDE 126: GASES - COMPRESSED OR LIQUEFIED (INCLUDING REFRIGERANT GASES)/ Protective Clothing: Wear positive pressure self-contained breathing apparatus (SCBA). Wear chemical protective clothing that is specifically recommended by the manufacturer. It may provide little or no thermal protection. Structural firefighters' protective clothing will only provide limited protection.
/GUIDE 126: GASES - COMPRESSED OR LIQUEFIED (INCLUDING REFRIGERANT GASES)/ Evacuation: Large spill: Consider initial downward 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.
/GUIDE 126: GASES - COMPRESSED OR LIQUEFIED (INCLUDING REFRIGERANT GASES)/ Fire: Use extinguishing agent suitable for type of surrounding fire. Small fires: Dry chemical or CO2. Large fires: Water spray, fog or regular foam. 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. Some of these materials, if spilled, may evaporate leaving a flammable residue.
