5, Upper: 100
Solubility in Water:
Extinguishing Media:
Do not extinguish flames due to possibility of explosive re-ignition. Allow fire to burn out.
Special Procedures for Fire Fighters:
Extremely flammable gas. Do not approach without breathing apparatus and fire-proof clothing.
All Spills:
When possible, remove containers from area of fire.
Cool containers from a distance without extinguishing flames. Explosive re-ignition is a danger.
When possible, remove ignition source.
Use pressure relief device on container to vent contents exposed to high temperature.
Avoid ANY contact with copper, mercury, or their alloys, due to explosion risk.
Contain area; vapor can travel through air currents and ignite in areas other than disaster area.
Allow fire to burn out; do not extinguish: if necessary, reduce gas with fog or fine water spray.
Special Equipment:
Full protective clothing, including respirable fume respirator, welding gloves, splash goggles, steel boots, full fire-protective suit, head guard.
Atmospheric testing equipment recommended.
Health Hazards:
Eyes:
Irritation, increased tear production, frost bite of the eye, ulceration.
Ingestion:
Unlikely, but can cause frost bite of the lips, mouth, and throat; vomiting if swallowed.
Inhalation:
Upper airway irritation, cough, choking, shortness of breath, breathing difficulty, vomiting, narrowing of major airways, fluid in lungs, lung lesions, upper airway closure resulting in death, abdominal pain, un-coordination, unconsciousness.
Skin:
Frost bite, first-degree chemical...
ical burns.

Extinguishing Media:
Use dry chemical, CO2 or water spray for flames.
Special Procedures for Fire Fighters:
Highly flammable and reactive, use full fireproof clothing.
Poisonous gases produced in fire, use self-contained breathing apparatus.
Containers are explosive in fire, cool containers from a distance.
For Fire:
Use dry chemical, CO2 or water spray for flames.
Cool containers with water spray to help avoid explosion.
When possible, remove containers from flame.
Poisonous gases are created during fire: Use self-contained breathing apparatus.
Vapors travel via airways to other ignition points; contain leaks quickly and isolate area.
Hydrazine will ignite wood, paper, and oil; avoid contact with all combustibles.
For Spills:
Remove all possible ignition sources quickly.
Absorb liquids in vermiculite, dry sand,
earth, or a similar material and deposit in sealed containers.
Ventilate area well following clean up.
Avoid confining hydrazine;
