If adverse effects occur, remove to uncontaminated area. Give artificial respiration if not breathing. Get immediate medical attention. 



If frostbite or freezing occur, immediately flush with plenty of lukewarm water (105-115 F; 41-46 C). DO NOT USE HOT WATER. If warm water is not available, gently wrap affected parts in blankets. Get immediate medical attention. 



Contact with liquid: Immediately flush eyes with plenty of water for at least 15 minutes. Then get immediate medical attention. 



If a large amount is swallowed, get medical attention. 









See Section 9 for Flammability Properties 



Severe fire hazard. Containers may rupture or explode if exposed to heat. 



carbon dioxide, regular dry chemical Large fires: Flood with fine water spray. 



Move container from fire area if it can be done without risk. Cool containers with water spray until well after the fire is out. Stay away from the ends of tanks. For fires in cargo or storage area: Cool containers with water from unmanned hose holder or monitor nozzles until well after fire is out. If this is impossible then take the following precautions: Keep unnecessary people away, isolate hazard area and deny entry. Let the fire burn. Withdraw immediately in case of rising sound from venting safety device or any discoloration of tanks due to fire. For tank, rail car or tank truck: Stop leak if possible without personal risk. Let burn unless leak can be stopped immediately. For smaller tanks or cylinders, extinguish and isolate from other flammables. Evacuation radius: 800 meters (1/2 mile). Do not attempt to extinguish fire unless flow of material can be stopped first. Flood with fine water spray. Cool containers with water spray until well after the fire is out. Apply water from a protected location or from a safe distance. Avoid inhalation of material or combustion by-products. Stay upwind and keep out of low areas. Evacuate if fire gets out of control or containers are directly exposed to fire. Evacuation radius: 500 meters (1/3 mile). Consider downwind evacuation if material is leaking. 



oxides of carbon, hydrogen fluoride, fluorinated compounds, carbonyl fluoride 













Avoid heat, flames, sparks and other sources of ignition. Do not touch spilled material. Stop leak if possible without personal risk. Reduce vapors with water spray. Keep unnecessary people away, isolate hazard area and deny entry. Remove sources of ignition. Ventilate closed spaces before entering. 









Store and handle in accordance with all current regulations and standards. Store in a cool, dry place. Store in a well-ventilated area. Store in a tightly closed container. Store below 52 C. Keep away from heat, sparks and flame. Subject to storage regulations: U.S. OSHA 29 CFR 1910.101. Keep separated from incompatible substances. 

Component Exposure Limits 

Biological limit value 



Ventilation equipment should be explosion-resistant if explosive concentrations of material are present. Provide local exhaust ventilation system. Ensure compliance with applicable exposure limits. 



Eyes/Face For the gas: Eye protection not required, but recommended. For the liquid: Wear splash resistant safety goggles. Contact lenses should not be worn. Provide an emergency eye wash fountain and quick drench shower in the immediate work area. 



For the gas: Protective clothing is not required. For the liquid: Wear appropriate protective, cold insulating clothing. 



Wear insulated gloves. 



Under conditions of frequent use or heavy exposure, respiratory protection may be needed. Respiratory protection is ranked in order from minimum to maximum. Consider warning properties before use. For Unknown Concentrations or Immediately Dangerous to Life or Health - Any supplied-air respirator with a full facepiece that is operated in a pressure-demand or other positive-pressure mode in combination with an auxiliary self-contained breathing apparatus operated in pressure-demand or other positive-pressure mode. Any self-contained breathing apparatus that has a full facepiece and is operated in a pressure-demand or other positive-pressure mode.

Component Carcinogenicity

None of this product's components are listed by ACGIH, IARC, NTP, DFG or OSHA

Stimulants such as epinephrine may induce ventricular fibrillation. 



METHYLENE FLUORIDE: Overexposure may cause central nervous system depression with headache, dizziness, nausea, confusion, incoordination, drowsiness or unconsciousness These effects appear to reverse when oxygen deficiency has been corrected In high concentrations, may cause asphyxiation Exposure at concentrations of 315,000 ppm and greater produced lethargy and temporary loss of mobility in rats Cardiac sensitization occurred in one of 12 dogs exposed to a concentration of 250,000 ppm Guinea pigs exposed to 75,000 ppm exhibited pathological changes in the lungs, liver, kidneys and spleen.



METHYLENE FLUORIDE Repeated exposure may cause pathological changes of the lungs, liver, spleen and kidneys.
