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
If frostbite or freezing occur, immediately flush with plenty of lukewarm water (105-115 F; 41-46 C). DO NOT USE
HOT WATER. If warm water is not available, gently wrap affected parts in blankets. Get immediate medical
attention.

Eyes
Contact with liquid: Immediately flush eyes with plenty of water for at least 15 minutes. Then get immediate
medical attention.
Ingestion
If a large amount is swallowed, get medical attention.
Note to Physicians
For inhalation, consider oxygen.
* * * Section 5 - FIRE FIGHTING MEASURES * * *
See Section 9 for Flammability Properties
NFPA Ratings: Health: 2 Fire: 0 Reactivity: 0
Hazard Scale: 0 = Minimal 1 = Slight 2 = Moderate 3 = Serious 4 = Severe
Flammable Properties
Negligible fire hazard. Containers may rupture or explode if exposed to heat.
Extinguishing Media
carbon dioxide regular dry chemical
Large fires: Use regular foam or flood with fine water spray.
Fire Fighting Measures
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. Withdraw immediately in case of rising sound from venting safety
device or any discoloration of tanks due to fire. For tank, rail car or tank truck, evacuation radius: 800 meters (1/2
mile). Use extinguishing agents appropriate for surrounding fire. Cool containers with water spray until well after
the fire is out. Apply water from a protected location or from a safe distance. Do not get water directly on material.
Reduce vapors with water spray. Avoid inhalation of material or combustion by-products. Stay upwind and keep
out of low areas. Consider downwind evacuation if material is leaking.
Thermal Decomposition Products
Combustion: phosgene, halogenated anilines, hydrochloric acid, carbonyl fluoride, chlorine, hydrogen fluoride,
fluorocarbons, hydrogen chloride

* * * Section 6 - ACCIDENTAL RELEASE MEASURES * * *
Occupational spill/release
Stop leak if possible without personal risk. Keep unnecessary people away, isolate hazard area and deny entry.
Stay upwind and keep out of low areas. Notify Local Emergency Planning Committee and State Emergency
Response Commission for release greater than or equal to RQ (U.S. SARA Section 304). If release occurs in the
U.S. and is reportable under CERCLA Section 103, notify the National Response Center at (800)424-8802 (USA)
or (202)426-2675 (USA).
