MAJOR HEALTH HAZARDS: difficulty breathing PHYSICAL HAZARDS: Containers may rupture or explode if exposed to heat. POTENTIAL HEALTH EFFECTS: INHALATION: SHORT TERM EXPOSURE: nausea, vomiting, difficulty breathing, irregular heartbeat, headache, fatigue, dizziness, disorientation, emotional disturbances, tingling sensation, loss of coordination, suffocation, convulsions, unconsciousness, coma, death LONG TERM EXPOSURE: no information is available SKIN CONTACT: SHORT TERM EXPOSURE: no information on significant adverse effects LONG TERM EXPOSURE: no information is available EYE CONTACT: SHORT TERM EXPOSURE: no information on significant adverse effects LONG TERM EXPOSURE: no information is available INGESTION: SHORT TERM EXPOSURE: no information on significant adverse effects LONG TERM EXPOSURE: no information is available CARCINOGEN STATUS: OSHA: No NTP: No IARC: No

Part 4: First Aid Measures

INHALATION: If adverse effects occur, remove to uncontaminated area. Give artificial respiration if not breathing. If breathing is difficult, oxygen should be administered by qualified personnel. Get immediate medical attention. SKIN CONTACT: Wash exposed skin with soap and water. EYE CONTACT: Flush eyes with plenty of water. INGESTION: If a large amount is swallowed, get medical attention. NOTE TO PHYSICIAN: For inhalation, consider oxygen

Part 5: Fire Fighting Measures

FIRE AND EXPLOSION HAZARDS: Negligible fire hazard. Containers may rupture or explode if exposed to heat. EXTINGUISHING MEDIA: carbon dioxide, regular dry chemical Large fires: Use regular foam or flood with fine water spray. FIRE FIGHTING: 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. 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, evacuation radius: 800 meters (1/2 mile).

Part 6: Accidental Release Measures

OCCUPATIONAL RELEASE: Stop leak if possible without personal risk. Keep unnecessary people away, isolate hazard area and deny entry. Stay upwind and keep out of low areas

Part 7: Handling and Storage

STORAGE: Store and handle in accordance with all current regulations and standards. Subject to storage regulations: U.S. OSHA 29 CFR 1910.101. Cylinder temperature should not exceed 125 F (52 C). 29 CFR Subpart "H"-Hazardous Materials. National Fire Protection Association publication #55, "Standard for the Storage, Use and Handling of Compressed and Liquified Gases in Portable Cylinders". Compressed Gas Association publication P-1, "Safe Handling of Compressed Gases in Containers". Store and handle in accordance with current regulations and standards: OSHA 29 CFR 1910.101

Part 8: Exposure Controls, Personal Protection

EXPOSURE LIMITS: HELIUM: ACGIH (simple asphyxiant) VENTILATION: Provide local exhaust ventilation system. Ensure compliance with applicable exposure limits. EYE PROTECTION: Eye protection not required, but recommended. CLOTHING: Protective clothing is not required. GLOVES: Protective gloves are not required. RESPIRATOR: 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 full facepiece and operated in a pressure-demand or other positive-pressure mode in combination with a separate escape supply. Any self-contained breathing apparatus with a full facepiece.

MOLECULAR WEIGHT: 4.0026 MOLECULAR FORMULA: HE BOILING POINT: -452 F (-269 C) FREEZING POINT: -458 F (-272 C) @ 26 atm VAPOR PRESSURE: 1719 mmHg @ -268 C VAPOR DENSITY (air=1): 0.138 SPECIFIC GRAVITY: Not applicable DENSITY: 0.1785 g/L @ 0 C WATER SOLUBILITY: 0.94% @ 0 C PH: Not applicable VOLATILITY: Not applicable ODOR THRESHOLD: Not available EVAPORATION RATE: Not applicable VISCOSITY: 0.02012 cP @ 26.8 C COEFFICIENT OF WATER/OIL DISTRIBUTION: Not applicable SOLVENT SOLUBILITY: Insoluble: alcohol

Part 10: Stability and Reactivity

REACTIVITY: Stable at normal temperatures and pressure. CONDITIONS TO AVOID: Protect from physical damage and heat. Containers may rupture or explode if exposed to heat. INCOMPATIBILITIES: HELIUM: No data available. HAZARDOUS DECOMPOSITION: Thermal decomposition products: miscellaneous decomposition products POLYMERIZATION: Will not polymerize

Part 11: Toxicological Information

HEALTH EFFECTS: INHALATION: Do not breathe gas. HELIUM: Inhalation of mixtures of helium and oxygen may cause distorted speech, increased loss of body heat, and gas emboli at the junction of skin and subcutaneous fat or body fat and blood vessels. See information on simple asphyxiants. ACUTE EXPOSURE: SIMPLE ASPHYXIANTS: The symptoms of asphyxia depend on the rapidity with which the oxygen deficiency develops and how long it continues. In sudden acute asphyxia, unconsciousness may be immediate. With slow development there may be rapid respiration and pulse, air hunger, dizziness, reduced awareness, tightness in the head, tingling sensations, incoordination, faulty judgement, emotional instability, and rapid fatigue. As the asphyxia progresses, nausea, vomiting, collapse, unconsciousness, convulsions, deep coma and death are possible. CHRONIC EXPOSURE: SIMPLE ASPHYXIANTS: No data available. SKIN CONTACT: ACUTE EXPOSURE: HELIUM: No adverse effects have been reported from the gas. Due to rapid evaporation, the cryogenic liquid may cause frostbite with redness, tingling, and pain or numbness. In more severe cases, the skin may become hard and white and develop blisters. CHRONIC EXPOSURE: HELIUM: No data available. EYE CONTACT: ACUTE EXPOSURE: HELIUM: No adverse effects have been reported from the gas. Due to rapid evaporation, the cryogenic liquid may cause frostbite with redness, pain, and blurred vision. CHRONIC EXPOSURE: HELIUM: No data available. INGESTION: ACUTE EXPOSURE: HELIUM: Ingestion of a gas is unlikely. If swallowed, the cryogenic liquid may cause frostbite damage to the lips, mouth, and mucous membranes. CHRONIC EXPOSURE: HELIUM: No data available
