delayed. Persons receiving significant exposure should be observed 24-
48 hours for signs of respiratory distress. Persons sensitized to
Diisocyanates should consult a physician before working with respiratory
irritants or sensitizers.
5. FIRE-FIGHTING MEASURES
EXTINGUISHING MEDIA: Use water fog, foam, carbon dioxide or dry
chemical. Do not use solid water stream. Solid stream of water into hot
product may cause violent steam generation or eruption.
SPECIFIC HAZARDS: Water contamination will produce Carbon Dioxide.
Do not re-seal contaminated containers as pressure buildup may rupture.
SPECIAL PROTECTIVE EQUIPMENT & PRECAUTIONS FOR
FIREFIGHTERS: Wear approved positive pressure, self-contained
breathing apparatus and full body protective clothing.
6. ACCIDENTAL RELEASE MEASURES
PERSONAL PRECAUTIONS, PROTECTIVE EQUIPMENT AND
EMERGENCY PROCEDURES: Clear non-emergency personnel from the
area. Ventilate area. Wear appropriate protective clothing to prevent eye
and skin contact and respiratory protection.
METHODS AND MATERIALS FOR CONTAINMENT AND CLEANUP:
Cover with an inert absorbent material and collect into an appropriate
container for disposal. Do not seal the container since CO2 is generated
on contact with moisture and dangerous pressure buildup can occur.
Decontaminate floor area with a mixture of water plus isopropyl alcohol
(25%), household ammonia (15%), and detergent (5%).
7. HANDLING AND STORAGE
HANDLING: Avoid inhalation of vapors and spray mists. Use in well-
ventilated areas. Avoid contact with skin and eyes. Wash thoroughly after
handling. Do not eat, drink or smoke in the work area. Keep container
closed when not in use.
STORAGE: Store indoors at temperatures between 65F and 75F (18C &
24C). Recommend storage in original, unopened containers. Protect
from atmospheric moisture and water since isocyanates reacts with water
to form CO2, leading to potentially dangerous pressure buildup in sealed
containers.

10. STABILITY AND REACTIVITY
REACTIVITY: Avoid moisture. Isocyanates react with many materials
and the rate of reaction increases with temperature. Reaction with water
generates carbon dioxide (CO2) and heat.
CHEMICAL STABILITY: Stable under recommended conditions.
POSSIBILITY OF HAZARDOUS REACTION: Elevated temperatures,
over 347F (175C) can cause hazardous polymerization. Polymerization
can be catalyzed by strong bases or water. Reaction with water
generates carbon dioxide (CO2), and generates heat and pressure in
closed systems.
CONDITIONS TO AVOID: Avoid moisture and temperatures below 60F
(18C) and above 120F (49C).
INCOMPATIBLE MATERIALS: Avoid contact with water, acids, bases,
alcohols, and strong oxidizers.
HAZARDOUS DECOMPOSITION PRODUCTS: Possibly isocyanate
vapor, carbon monoxide, nitrogen oxides, and traces of hydrogen cyanide.
11. TOXICOLOGICAL INFORMATION
HUMAN EFFECTS OF OVEREXPOSURE
Inhalation: May cause respiratory sensitization in susceptible individuals.
At room temperature, vapors are minimal due to low volatility. If heated or
sprayed as an aerosol, excessive concentrations are attainable that could
be hazardous on single exposure. Excessive exposure may cause
irritation of the eyes, upper respiratory tract and lungs. Effects may be
delayed. Decrease ventilation capacity has been associated with
exposure to similar Isocyanates; it is possible that exposure to MDI may
cause impairment of lung function. Vapors or aerosols may cause
respiratory irritation and possibly pulmonary edema, or respiratory
sensitization. For individuals sensitized to MDI, exposure may result in
allergic respiratory reactions (e.g., coughing, wheezing, difficulty
breathing).
Ingestion: Single oral dose toxicity is low. May cause adverse
gastrointestinal effects.
Skin contact: May cause irritation. Repeated skin contact may cause
an allergic skin reaction. Studies in animals indicate skin contact with
isocyanates may elicit respiratory sensitization.
ACUTE EFFECTS Medical conditions aggravated by exposure: Asthma,
other respiratory disorders (bronchitis, emphysema, bronchial hyper-
reactivity), skin allergies, eczema. Repeated or prolonged exposure to
isocyanates may cause an allergic sensitization of the respiratory tract
causing an asthma-like response upon re-exposure. Repeated
overexposure to isocyanates has been associated with decreased lung
function. Repeated or prolonged dermal contact with this product may
cause allergic skin sensitization in some individuals.
