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
Warning: hydrazine vapor in air is flammable at 4.7 to 100%
hydrazine by volume - handle under nitrogen! Some metals and
alloys including monel, bronze, brass, cadmium, gold,
molybdenum, and stainless steel with more than 0.5% molybdenum
or rust cause decomposition of hydrazine
EXTINGUISHING MEDIA
Suitable: Water spray. Carbon dioxide. Dry chemical powder.
SPECIAL RISKS
