EXTINGUISHING MEDIAAll are suitable. While product is non-flammable and extinguishes fires at sufficient concentration, can undergo thermal decomposition if involved in fires where quantity of product is insufficient to extinguish. Thermal decomposition products may be toxic or corrosive.
UNUSUAL FIRE AND EXPLOSION HAZARDSContainer rupture possible if pressure and temperature relief valves should fail.
SPECIAL FIRE FIGHTING PROCEDURESEmploy water spray from a safe distance to prevent container rupture. If containers should rupture, use self contained breathing apparatus. Product is non-flammable, but denser than air, posing asphyxiation risk. Thoroughly ventilate affected area to remove product and any decomposition products before allowing re-entry.

HAZARDOUS DECOMPOSTION PRODUCTSThermal decomposition products may include hydrogen fluoride, carbon monoxide and carbon dioxide.
SECTION VI – HEALTH HAZARD DATA
THRESHOLD LIMIT VALUEN/A
POTENTIAL EXPOSURE ROUTESInhalation – Yes
Eye contact – Yes
Skin contact – Yes
Ingestion – No
SIGNS AND SYMPTOMS OF OVEREXPOSUREInhalation of excessive concentrations in air may induce symptoms of hypoxia (headache, nausea, dizziness, loss of consciousness) or cardiac sensitization (irregular pulse or arrhythmia). Product is a cryogenic gas. Direct skin contact at point of release may cause symptoms of frostbite due to evaporative cooling (cold, white, discolored skin that, in severe cases, may exhibit blistering).
MEDICAL CONDITIONS POTENTIALLY AGGRAVATED BY EXPOSUREPre-existing cardiac, respiratory or CNS disorders may be exacerbated by overexposure. Epinephrine or sympathomemetic drugs may increase susceptibility to cardiac irregularities upon overexposure.
CARCINOGENICITYNTP Program – No
IARC Monographs – No
OSHA – No
ACGIH – No
Other – No
MUTAGENICITYS. typhimurium assay – No
Mouse lymphoma assay – No
Mouse micronuclei assay – No
LC30 4 hour rate> 800,000 ppm
EMERGENCY AND FIRST AID PROCEDURESInhalation – Move to fresh air. Artificial respiration if not breathing. Administer oxygen if breathing is labored. Seek medical attention.

Eye contact – Flush/irrigate with fresh water. Seek medical attention.

Skin contact – Flush/irrigate (spray) with water. Apply sterile dressing as necessary. Seek medical treatment for symptoms of frostbite.

Ingestion – N/A

NOTE TO PHYSICIANS:
In treating cases of overexposure through inhalation, use of epinephrine, sympathomemetics or other stimulants is contraindicated as such compounds increase susceptibility to cardiac sensitization (irregular pulse or arrhythmia).

SECTION VII – SPILL/LEAK PROCEDURES AND SPECIAL PRECAUTIONS
HANDLING AND STORAGE PRECAUTIONSStore in a cool, dry, well-ventilated area separate from incompatible materials. Protect containers from mechanical damage. Follow fire equipment manufacturer’s instructions for operation, inspection, maintenance and repair of portable extinguishers and fixed extinguishing systems.
OTHER PRECAUTIONSProhibit backfeed into containers.
RELEASE OR SPILL PROCEDURESEvacuate and ventilate the affected area. Prohibit general entry into areas where high concentrations may exist, particularly confined or poorly ventilated areas. Keep in mind that this product is denser than air and that concentrations will be higher at lower levels (sewers, basements or pits). Trained personnel should use self-contained breathing apparatus when entering areas where high concentrations may exist.
WASTE DISPOSALProduct can be reclaimed unless contaminated. Contact distributor to arrange reclamation. Otherwise, disposal should be in accordance with applicable law, generally by incineration at a qualified facility with an appropriate scrubber and other emission control technology.
SECTION VIII – SPECIAL PROTECTION INFORMATION
RESPIRATORY PROTECTIONNIOSH/MSHA approved self-contained breathing apparatus for entry into areas where high concentrations may exist.
VENTILATIONPassive ventilation (windows, doors, etc.) generally adequate for small areas. Mechanical ventilation for control of large areas and storage or filling facilities.
DERMAL PROTECTIONLined, neoprene gloves for handling liquid product.
EYE PROTECTIONShatterproof chemical splash goggles when handling liquid or working on pressurized containers.
OTHER PROTECTIVE EQUIPMENTClothing to minimize contact with liquid product or at potential points of release.
OTHER PROTECTIVE PRACTICESEmploy prudent confined space entry and related procedures (confirm equipment is free of product and has been ventilated, etc.). As with all chemical products, wash thoroughly after handling and wash contaminated clothing before re-use.
