3 - Hazards Identification
SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Reacts violently with water. Very toxic by inhalation and if
swallowed. Causes burns.
4 - First Aid Measures
AFTER INHALATION
If inhaled, remove to fresh air. If not breathing give
artificial respiration. If breathing is difficult, give oxygen.
AFTER SKIN CONTACT
In case of skin contact, flush with copious amounts of water for
at least 15 minutes. Remove contaminated clothing and shoes.

separating the eyelids with fingers. Call a physician.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician immediately. Do not induce vomiting.
GENERAL INFORMATION
Keep under medical observation. Symptoms may be delayed.
5 - Fire Fighting Measures
CONDITIONS OF FLAMMABILITY
Water hydrolyzes material liberating acidic gas which in contact
with metal surfaces can generate flammable and/or explosive
hydrogen gas.
EXTINGUISHING MEDIA
Suitable: Use water spray or fog nozzle to keep cylinder cool.
Move cylinder away from fire if there is no risk.
SPECIAL RISKS
Specific Hazard(s): Emits toxic fumes under fire conditions.
SPECIAL PROTECTIVE EQUIPMENT FOR FIREFIGHTERS
Wear self-contained breathing apparatus and protective clothing
to prevent contact with skin and eyes.
6 - Accidental Release Measures
PERSONAL PRECAUTION PROCEDURES TO BE FOLLOWED IN CASE OF LEAK OR SPILL
Evacuate area and keep personnel upwind. Shut off leak if there
is no risk.
PROCEDURE(S) OF PERSONAL PRECAUTION(S)
Wear self-contained breathing apparatus, rubber boots, and heavy
rubber gloves.
METHODS FOR CLEANING UP
Cover with dry lime or soda ash, pick up, keep in a closed
container, and hold for waste disposal. Ventilate area and wash
spill site after material pickup is complete.
7 - Handling and Storage
HANDLING
Directions for Safe Handling: Do not breathe gas. Do not get in
eyes, on skin, on clothing. Avoid prolonged or repeated exposure.
STORAGE
