SECTION 2 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.

SECTION 3 FIRE FIGHTING MEASURES
Fire and explosion hazards Severe fire hazard. Severe explosion hazard. Vapor/air mixtures are explosive. Pressurized containers may rupture or explode if exposed to sufficient heat. Electrostatic discharges may be generated by flow or agitation resulting in ignition or explosion
Extinguishing media Carbon dioxide, regular dry chemical
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. 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.

SECTION 4 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.

SECTION 5 HANDLING AND STORAGE
Storage Store and handle in accordance with all current regulations and standards.
Grounding and bonding required. Subject to storage regulations : Keep separated from incompatible substances.

SECTION 6 EXPOSURE CONTROLS , PERSONAL PROTECTION
Exposure limits Hydrogen
Ventilation Ventilation equipment should be explosion-resistant if explosive concentrations of material are present. 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 Wear appropriate chemical resistant gloves.
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.

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.
