3 - Hazards Identification
SPECIAL INDICATION OF HAZARDS TO HUMANS AND THE ENVIRONMENT
Harmful by inhalation and if swallowed. Causes burns. May cause
sensitization by inhalation and skin contact.
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.
Call a physician.
AFTER EYE CONTACT
In case of contact with eyes, flush with copious amounts of
water for at least 15 minutes. Assure adequate flushing by
separating the eyelids with fingers. Call a physician.
AFTER INGESTION
If swallowed, wash out mouth with water provided person is
conscious. Call a physician. Do not induce vomiting.
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: Carbon dioxide, dry chemical powder, or appropriate
foam.
Unsuitable: Do not use water.
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.
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.
