Medical Cond Aggravated by Exposure:

First Aid: 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 skin with soap and water for at least 15 minutes while

of water, do NOT induce vomiting. Get immediate medical attention.
NOTE TO PHYSICIAN: For inhalation, consider oxygen. Avoid gastric
lavage or emesis.

Flash Point:not flammable
Extinguishing Media:carbon dioxide, regular dry chemical Large fires:
Use regular foam or flood with fine water spray.
Fire Fighting Procedures:Do not get water inside container. 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. Keep unnecessary people away, isolate
hazard area and deny entry.
Unusual Fire/Explosion Hazard:Negligible fire hazard. Containers may
rupture or explode if exposed to heat.

Spill Release Procedures:Stop leak if possible without personal risk.
Reduce vapors with water spray. Do not get water directly on
material. Do not get water inside container. Keep unnecessary
people away, isolate hazard area and deny entry. Small spills:
Flood with water. Large spills: Dike for later disposal. Stay
upwind and keep out of low areas. Ventilate closed spaces before
entering. Evacuation radius: 150 feet. Notify Local Emergency
Planning Committee and State Emergency Response Commission for
