Fire Fighting Procedures
If material 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. /Refrigerants NEC, gas or liquid, nonflammable (refrigerant, gas, NOS or dispersant gas, NOS/
DOT Emergency Guidelines
/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 ... . 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.
/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.
/GUIDE 126: GASES - COMPRESSED OR LIQUEFIED (INCLUDING REFRIGERANT GASES)/ Spill or Leak: 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.
/GUIDE 126: GASES - COMPRESSED OR LIQUEFIED (INCLUDING REFRIGERANT GASES)/ 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. Remove and isolate contaminated clothing and shoes. 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.
Reactivities and Incompatibilities
Dangerous ... on contact with acid or acid fumes, they emit highly toxic fumes. /Fluorides/
Other Preventative Measures
SUFFICIENT EXHAUST & GENERAL VENTILATION SHOULD BE PROVIDED TO KEEP VAPOR CONCN BELOW RECOMMENDED LEVELS. /FLUOROCARBONS/
INHALATION OF FLUOROCARBON VAPORS SHOULD BE AVOIDED. /FLUOROCARBONS/
Forced air ventilation at the level of vapor concentration together with the use of individual breathing devices with independent air supply will minimize the risk of inhalation. Lifelines should be worn when entering tanks or other confined spaces. /Fluorocarbons/
Enclosure of process materials and isolation of reaction vessels and proper design and operation of filling heads for packaging and shipping /are administrative controls that may be instituted to limit occupational exposure to fluorocarbons during manufacture, packaging, and use/. /Fluorocarbons/
If material not involved in fire: attempt to stop leak if without undue personnel hazard. /Refrigerants, NEC, gas or liquid, nonflammable (refrigerant, gas, NOS, or dispersant gas, NOS/
FILLING AREAS SHOULD BE MONITORED TO ENSURE ... AMBIENT CONCN OF FLUOROCARBONS DOES NOT EXCEED 1000 PPM ... INHALATION OF FLUOROCARBON VAPORS SHOULD BE AVOIDED ... IF INHALATION OCCURS, EPINEPHRINE OR OTHER SYMPATHOMIMETIC AMINES & ADRENERGIC ACTIVATORS SHOULD NOT BE ADMIN SINCE THEY WILL FURTHER SENSITIZE HEART TO DEVELOPMENT OF ARRHYTHMIAS. /FLUOROCARBONS/
APPEARANCE OF TOXIC DECOMP PRODUCTS SERVES AS WARNING OF OCCURRENCE OF THERMAL DECOMP & DETECTION OF SHARP ACRID ODOR WARNS OF PRESENCE ... HALIDE LAMPS OR ELECTRONIC LEAK DETECTORS MAY ALSO BE USED. ADEQUATE VENTILATION ALSO AVOIDS PROBLEM OF TOXIC DECOMPOSITION PRODUCTS. /FLUOROCARBONS/
Protective Equipment and Clothing
Many of the fluorocarbons are good solvents of skin oil, so protective ointment should be used. /Fluorocarbons/
NEOPRENE GLOVES, PROTECTIVE CLOTHING, & EYE PROTECTION MINIMIZE RISK OF TOPICAL CONTACT. DEGREASING EFFECT ON SKIN CAN BE TREATED WITH LANOLIN OINTMENT. /FLUOROCARBONS/
FORCED AIR VENTILATION @ LEVEL OF VAPOR CONCN TOGETHER WITH USE OF INDIVIDUAL BREATHING DEVICES WITH INDEPENDENT AIR SUPPLY WILL MINIMIZE RISK OF INHALATION. LIFELINES SHOULD BE WORN WHEN ENTERING TANKS OR OTHER CONFINED SPACES. /FLUOROCARBONS/
