HAZARDS IDENTIFICATION
EMERGENCY OVERVIEW : Misuse or intentional inhalation abuse can cause
suffocation or death. Direct eye or skin contact with the liquid or cold gas can cause chilling or possibly frostbite on exposed tissues.
ACUTE HEALTH EFFECTS
EYE CONTACT : Direct eye contact may induce the symptoms for frostbite or cold burns.
SKIN CONTACT : Direct skin contact may induce the symptoms for frostbite or cold burns.
INHALATION : Inhalation may induce the symptoms of headache, nausea, dizziness, loss of consciousness, or cardiac sensitization (irregular pulse or arrhythmia).
INGESTION : Not considered as a potential route of exposure.
CHRONIC HEALTH EFFECTS : Not known.
EFFECTS OF REPEATED EXPOSURE : Persons with cardiac, respiratory, or central nervous
system disorders may be susceptible to the effects of an over exposure. The use of epinephrine or sympathomimetic drugs may increase susceptibility to cardiac irregularities upon over exposure.
EYE CONTACT : Flush/ irrigate with fresh water. Seek medical help.
SKIN CONTACT : Flush/ irrigate with fresh water. Seek medical help if frostbite occurs.
INHALATION : Move to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
INGESTION : No information available.
NOTES TO PHYSICIANS AND FIRST AIDERS: The use of epinephrine or similar compounds can
increase susceptibility to heart irregularities caused by over exposure to this compound.
FLASH POINT : Not applicable.
FLAMMABLE LIMIT : Not applicable. (in air, % by volume)
AUTO – IGNITION TEMPERATURE : Not applicable.
EXTINGUISHING MEDIA : All conventional media are suitable.
UNUSUAL FIRE AND EXPLOSION : Although containers are provided with pressure and HAZARDS temperature relief devices, containers can rupture if exposed to localized heat. Thermal decomposition products may be toxic or corrosive. SPECIAL FIRE FIGHTING PROCEDURES : Apply water spray from a safe distance to prevent possible container rupture. Use a self-contained breathing apparatus if containers rupture. Thoroughly ventilate affected area to remove product and any decomposition products before allowing re-entry.
PRODUCTS OF COMBUSTION : High temperature in a fire condition or glowing
metal surfaces may generate hazardous decomposition products, which include hydrogen fluoride (ACGIH TLV = 3 ppm), carbon monoxide, carbon dioxide, and others. ACCIDENTAL SPILL/RELEASE OR LEAK : Evacuate and ventilate affected area. Prohibit PROCEDURES general entry into areas where high concentrations may exist (especially confined or poorly ventilated areas). Note that the compound vapors are denser than air and thus the concentrations will be higher at lower levels.
PERSONAL PRECAUTIONS : Use appropriate personal protective equipment including self-contained breathing apparatus when entering the affected areas.
HANDLING : Practice precautions as would be used in handling any cryogenic gas.
STORAGE : Store in a cool, dry, well-ventilated area, and separate these products from other incompatible materials. Protect container from possible damage and keep container tightly closed. When used as fire fighting agent in fixed or portable extinguishing systems, follow equipment manufacturer’s instructions for operation, inspection, maintenance, and repair of the system.
VENTILATION : Passive ventilation (windows, doors, etc.) is generally adequate for small areas. Mechanical ventilation for areas used in large storage and filling facilities.
RESPIRATORY PROTECTION : Wear NIOSH/MSHA approved self-contained
breathing apparatus.
EYE/FACE & SKIN PROTECTION : Use chemical splash goggles to protect eye & face
when handling product. Use cryogenic gloves if handling liquid. Use protective clothing designed to minimize skin contact.
WORK HYGIENIC PRACTICES : Be prudent in confined space. As with all chemical
products, wash thoroughly after handling. Wash contaminated clothing before re-use.
