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: Severe fire hazard. Severe explosion hazard. Vapor/air mixtures are explosive. Containers may rupture or explode if exposed to heat. Electrostatic discharges may be generated by flow or agitation resulting in ignition or explosion. EXTINGUISHING MEDIA: carbon dioxide, regular dry chemical Large fires: 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. 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. Stop flow of gas. LOWER FLAMMABLE LIMIT: 4.0% UPPER FLAMMABLE LIMIT: 75% AUTOIGNITION: 932 F (500 C)

Part 6: Accidental Release Measures

OCCUPATIONAL RELEASE: 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.

Part 8: Exposure Controls, Personal Protection

EXPOSURE LIMITS: HYDROGEN: ACGIH (simple asphyxiant) VENTILATION: Ventilation equipment should be explosion-resistant if explosive concentrations of material are present.

Part 11: Toxicological Information

HEALTH EFFECTS: INHALATION: HYDROGEN: 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: HYDROGEN: 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: HYDROGEN: No data available. EYE CONTACT: ACUTE EXPOSURE: HYDROGEN: 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: HYDROGEN: No data available. INGESTION: ACUTE EXPOSURE: HYDROGEN: Ingestion of a gas is unlikely. If cryogenic liquid is swallowed, frostbite damage to the lips, mouth and mucous membranes may occur. CHRONIC EXPOSURE: HYDROGEN: No data available
