SECTION 4: FIRE & EXPLOSION HAZARD DATA
FLASH POINT: Greater than 100癋.
EXTINGUISHING MEDIA: Foam, CO2, dry chemical or water fog.
SPECIAL FIRE FIGHTING PROCEDURES: Firefighters must wear self contained breathing
apparatus and full protective clothing to prevent contact with toxic and/or irritating
fumes. Do not spray pool fires directly; a stream of water directed into hot, burning liquid
can cause frothing.
UNUSUAL FIRE & EXPLOSION HAZARD: Contamination with water will generate carbon
dioxide gas with possible pressure build up in confined areas. Carbon monoxide may be
involved if combustion is incomplete. This product is non-flammable and will not
explode from mechanical impact.
SECTION 5: HEALTH HAZARD DATA
EFFECTS OF OVEREXPOSURE: Skin contact may cause irritation. Eye contact causes
irritation, redness, tearing and blurred vision.
EMERGENCY & FIRST AID: Eye contact; Flush with water for at least 15 minutes and call a
physician as soon as possible. Skin contact; Wash with soap and water and remove
contaminated clothing. Ingestion; See a Physician immediately.
PRIMARY ROUTES OF ENTRY: Dermal most likely.
MEDICAL CONDITIONS PRONE TO AGGRAVATION BY EXPOSURE: Repeated exposure
can cause allergic reaction with development of occupational asthma. Long term
exposure to low vapor concentrations may cause chronically progressive pulmonary
disease. Repeated skin contact can result in sensitization.

SECTION 6: REACTIVITY DATA
STABILITY: Stable
CONDITIONS TO AVOID: Temperature extremes and water contamination.
INCOMPATIBILITY: Avoid contact with strong oxidizing agents, water, alcohols, amines and
strong bases.
HAZARDOUS DECOMPOSITION PRODUCTS: Incomplete burning may produce carbon
monoxide and/or carbon dioxide.
HAZARDOUS POLYMERIZATION: Reacts slowly with water to produce CO2 gas.
SECTION 7: SPILL OR LEAK PROCEDURES
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Remove all
sources of ignition. In enclosed areas, cleanup personnel should wear self contained
breathing apparatus. Cover spills with sawdust, vermiculite, or other absorbent material.
Add an equal volume of a 6% ammonia solution in water and allow to react for 10
minutes. Collect into open containers and add more solution. Cover loosely to vent
carbon dioxide gas generated.
WASTE DISPOSAL METHOD: Dispose in accordance with local, state, and federal regulations.
SECTION 8: SPECIAL PROTECTION INFORMATION
RESPIRATORY PROTECTION: Use self-contained or supplied air breathing apparatus in
areas were the MDI concentrations are above the PEL or when the material is being
heated or spray applied.
VENTILATION (Local Exhaust): Good general room ventilation. Mechanical ventilation in
enclosed areas.
PROTECTIVE GLOVES: Chemical resistant gloves. Nitrile recommended.
EYE PROTECTION: Safety goggles or face shield.
OTHER PROTECTIVE EQUIPMENT: Eye bath & safety shower should be available.

SECTION 9: SPECIAL PRECAUTIONS & TOXICOLOGICAL PROPERTIES
SPECIAL PRECAUTIONS TO BE TAKEN IN HANDLING & STORING: Keep containers
closed and store in a cool dry place away from direct sunlight.
TOXICOLOGICAL PROPERTIES: Recent National Toxicology Program (NTP) studies have
shown that two chlorinated paraffins, C12/58% and C24/43% chlorine, increased the
incidence of tumors in laboratory animals when force fed in high doses in combination
with corn oil, over long periods of time. The relevance of these studies to the industrial
use of these paraffins by humans, if any, has not been determined. The International
Isocyanate Institute is currently sponsoring a lifetime study on polymeric MDI in rats for
carcinogenicity. Monomeric MDI is positive for mutagenicity in the Ames assay. Oral
LD50 (rats) is greater than 15800 mg/Kg. Dermal LD50 (rabbits)is greater than 7900
mg/Kg. Inhalation LC50 (rats - 2hr) is greater than 400 mg/M3 on dust of monomeric
MDI. Harmful or fatal is swallowed. Vapor harmful. May cause skin or eye irritation.
