FLASH POINT: A & B - Non-flammable liquids LEL: N/A UEL: N/A
EXTINGUISHING MEDIA: Foam, CO , dry chemical or water fog.

o
SPECIAL FIRE FIGHTING PROCEDURES: "B" component boils at less than 100 F and containers must be kept cool with water fog
to prevent rupture. Fire fighters must wear self-contained breathing apparatus and full protective clothing to prevent contact with
toxic and/or irritating fumes.
UNUSUAL FIRE AND EXPLOSION HAZARD: Contamination of "A" side with water will generate CO gas with possible build-up of
2
pressure in confined spaces. Carbon monoxide may be evolved if combustion is incomplete. Both components are non-flammable
and will not explode due to mechanical impact.
WARNING! When exposed to open flame, cured polyurethane foam will present a serious fire hazard.
==================================================================================================
SECTION V - HEALTH HAZARD DATA
==================================================================================================
EFFECTS of OVEREXPOSURE: Product Vapour can cause lacrimation, conjunctivitis and corneal edema giving rise to the perception
of "blue haze" or "fog". The effect is temporary and has no known residual effects.
EMERGENCY & FIRST AID: Eye Contact: Flush with water for 15 minutes and contact a physician as soon as possibly. Skin contact:
Wash with soap and water and remove-contaminated clothing. Ingestion: See a physician.
PRIMARY ROUTES of ENTRY: Dermal or inhalation most likely.
MEDICAL CONDITIONS PRONE TO AGGRAVATION BY EXPOSURE: Repeated exposure can cause an allergic reaction with
the development of occupational asthma. Long-term exposure to low Vapour concentrations may cause chronically progressive
pulmonary disease. Repeated skin contact can result in sensitization

SECTION VI - REACTIVITY DATA
==================================================================================================
STABILITY: Stable CONDITIONS TO AVOID: Temperature extremes and water contamination.
INCOMPATIBILITY: "A" side reacts with water, alcohols, amines, ammonia and carboxylic acids.
HAZARDOUS DECOMPOSITION PRODUCTS: Incomplete burning may produce nitrogen oxides, hydrogen cyanide, carbon
monoxide and/or carbon dioxide.
HAZARDOUS POLYMERIZATION: "A" component reacts slowly with water to produce CO gas.

==================================================================================================
SECTION VII - SPILL or LEAK PROCEDURES
==================================================================================================
STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: In enclosed areas, cleanup personnel should wear self-
contained breathing apparatus. Cover spills with sawdust or other absorbent material to minimize spreading of the material before
collecting. "A" component must be neutralized with 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 CO gas generated.

WASTE DISPOSAL METHOD: Dispose in accordance with local, provincial and federal regulations.
==================================================================================================
SECTION VIII - SPECIAL PROTECTION INFORMATION
==================================================================================================
RESPIRATORY PROTECTION: Use organic Vapour cartridges with a mechanical filter to remove airborne particles. Use supply air
breathing apparatus in enclosed areas.
VENTILATION: Mechanical equipment capable of keeping the Vapour concentration below the TLV.
PROTECTIVE GLOVES: Chemical resistant rubber or plastic gloves.
EYE PROTECTION: Safety goggles or face shield.
OTHER PROTECTIVE EQUIPMENT: Eyewash & safety shower should be available.
==================================================================================================
SECTION IX - 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. Opened "A" side containers should be blanketed with dry nitrogen before resealing if there is no moisture
contamination. If water contamination is suspected, do not reseal.
TOXICOLOGICAL PROPERTIES: 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
3
15800mg/Kg. Dermal LD50 (rabbits) is greater than 7900 mg/Kg. Inhalation LC50 (rats-2 hours) is greater than 400 mg/M on
dust of monomeric MDI. DANGER! Harmful or fatal if swallowed. Vapour harmful. May cause skin or eye irritation. Keep out
of the reach of children.
