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:
Remove contaminated clothing, jewelry, and shoes immediately. Wash
with soap or mild detergent and large amounts of water until no
evidence of chemical remains (at least 15-20 minutes). For burns,
cover affected area securely with sterile, dry, loose-fitting
dressing. Get medical attention. EYE CONTACT: Immediately flush
eyes with plenty of water for at least 15 minutes. Then get
immediate medical attention. INGESTION: If swallowed, drink plenty
of water, do NOT induce vomiting. Get immediate medical attention.
NOTE TO PHYSICIAN: For inhalation, consider oxygen. For skin
contact, consider ice water bath, iced alcohol, iced magnesium
sulfate, magnesium oxide/glycerin gels, calcium gluconate gel or
benzalkonium chloride solution. Avoid gastric lavage or emesis.

Flash Point:not flammable
Extinguishing Media:regular dry chemical, carbon dioxide, water,
regular foam Large fires: Use regular foam or flood with fine water
spray.
Fire Fighting Procedures: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. Use
extinguishing agents appropriate for surrounding fire. Flood with
fine water spray. Avoid inhalation of material or combustion
by-products. Stay upwind and keep out of low areas.
Unusual Fire/Explosion Hazard:Negligible fire hazard.

Neutralizing Agent:

Handling and Storage Precautions:Store and handle in accordance with
all current regulations and standards. Protect from physical
damage. Store in a well-ventilated area. Keep separated from
incompatible substances. Notify State Emergency Response Commission
for storage or use at amounts greater than or equal to the TPQ
(U.S. EPA SARA Section 302). SARA Section 303 requires facilities
storing a material with a TPQ to participate in local emergency
response planning (U.S. EPA 40 CFR 355.30). Subject to storage
regulations: U.S. OSHA 29 CFR 1910.101. Store in a cool, dry place.
