SECTION 4 ?FIRE AND EXPLOSION HAZARD DATA
Flash Point: 350癋 PMCC
Flammable Limits: Upper Explosive Limit/Lower Explosive Limit: UN/UN
Autoignition Temperature: UN
Flammability Classification: OSHA: Not regulated DOT: Not regulated
Appropriate Extinguishers: dry chemical, water fog, carbon dioxide, or foam.
Special Fire Fighting Procedures: Wear positive-pressure self contained breathing apparatus
(SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat pants, boots, and
gloves). Avoid contact with this material during fire fighting operations. If contact is likely,
change to full chemical resistant clothing with SCBA. If this will not provide sufficient fire
protection, consider fighting the fire from a remote location. For protective equipment in post-
fire or non-fire clean up situations, refer to the relevant sections. Isolate fire area and deny
unnecessary entry. Keep people away from material and fire. Water is not recommended, but
may be applied in large quantities as a fine spray when other extinguishing agents are not
available. Stay upwind. Keep out of low areas where gases (fumes) can accumulate. Do not
use a direct water stream, which may spread the fire. Use water spray to cool fire exposed
containers and fire affected zone until the fire is out. Fight fire from a protected location or a
safe distance. Consider the use of unmanned hose holder or monitor. Immediately withdraw all
personnel from area in case of rising sound from venting safety device or discoloration of the
container. Move the container from the fire area if this is possible without hazard.
Unusual Fire and Explosion Hazards: During a fire, smoke may contain the original material in
addition to the unidentified toxic and/or irritating compounds. Hazardous combustion products
may include but are not limited to: Nitrogen oxides, Isocyanate, hydrogen cyanide, carbon
monoxide, and carbon dioxide. Dense smoke is produced when products burns. At
temperatures greater than 400癋 (204癈), isocyanate can polymerize and decompose, which
can cause pressure build up in closed containers. Explosive rupture is possible. Therefore, use
cold water to cool fore exposed containers. Violent steam generation or eruption may occur
upon application of direct water to hot liquids. Spill of these organic liquids on hot fibrous
insulations may lead to lowering of the auto-ignition temperatures, possibly resulting in
spontaneous combustion. Product reacts with water. Reaction may produce heat and or
gases. Container may rupture from gas generation in a fire situation. This reaction may be
violent. Water fog, fine water spray, carbon dioxide, dry chemical, or ATC type foams may be
used to extinguish the fire. General-purpose synthetic foams (including AFFF) or protein foams
may function, but much less effectively. Do not use direct water stream. This may spread fire.
SECTION 5 ?HEALTH HAZARD INFORMATION

MATERIAL SAFETY DATA SHEET
Skin: Isocyanates react with skin protein and moisture and can cause irritation, which may include the
following symptoms: Redness, swelling, rash, scaling, or blistering. Prolonged or repeated
exposure may cause skin to stain. Skin contact may result in skin or respiratory sensitization,
but is not expected to result in absorption of amounts sufficient to cause other adverse effects.
Inhalation: Isocyanate vapors or mist at concentrations above the TLV can irritate the mucus
membranes in the respiratory tract, causing runny nose, sore throat, coughing, chest
discomfort, shortness of breath, and reduced lung function. Asthma type symptoms may
develop and may be immediate or delayed up to several hours.
Ingestion: Can cause irritation and corrosive action to the mouth and gastrointestinal tract. May be
harmful or fatal if swallowed.
Aggravated Medical Conditions: MDI concentrations below the exposure guidelines may cause
allergic respiratory reactions in individuals already sensitized. Overexposure may have liver
and/or adrenal affects.
Chronic Health Effects: Repeated overexposure can lead to isocyanate sensitization (Chemical
Asthma), which will cause the individual to react to a later exposure at levels well below the TLV
for isocyanate. Chronic overexposure may lead to permanent lung damage. Animals exposed
to MDI/Polymeric MDI at a level of 6 mg/M3 for the duration of their lifetime have developed lung
cancer.
SECTION 6 ?FIRST AID MEASURES
Inhalation: Move to an area free from risk of further exposure. Administer oxygen or artificial
respiration as needed. Obtain medical attention immediately.
NOTE TO THE PHYSICIAN: May cause respiratory sensitization or asthmatic symptoms.
Bronchodilators, expectorants, and antitussives may be of help. Respiratory symptoms,
including pulmonary edema, may be delayed. Persons receiving significant exposure
should be observed for 24 ?48 hours for signs of respiratory distress. No specific
antidote. Supportive care. Treatment based on judgment of the physician in response to
reactions of the patient.
Eyes: Flush eyes with large amounts of running water immediately for 15 minutes, lifting upper and
lower eyelids occasionally. Get medical attention immediately.
Skin: Remove contaminated clothing and launder thoroughly before reuse. Wash material from skin
thoroughly with soap and water. For severe exposure, use safety shower after removing
clothing. Seek medical attention. If irritation, rash or other symptoms develop, contact medical
assistance immediately.
Ingestion: DO NOT INDUCE VOMITING unless otherwise directed by medical personnel. Give 1-2
cups of milk or water to drink. Do not give anything by mouth to an unconscious person.
Get immediate medical attention.

SECTION 7 ?STABILITY AND REACTIVITY DATA
Stability: Material is normally chemically stable when stored in a cool, dry place. Store at
temperatures between 75癋 (24癈) and 105癋 (41癈). Product can decompose at elevated
temperatures, and may self react at temperatures above 320癋 (160癈)
Incompatibility: Avoid contact with moisture, aluminum, brass, copper, galvanized metals, zinc, acids,
alcohols, amines, ammonia, bases, metal components, humid air, and strong
oxidizers. Avoid unintended contact with polyols.
Hazardous Decomposition: Reaction with water will produce carbon dioxide, and heat. This may lead
to pressure buildup in closed containers. Hazardous decomposition
products depend upon temperature, air supply, and the presence of other
materials.
Hazardous Polymerization:. Product may self react at temperatures above 320癋 (160癈)
SECTION 8 ?ACCIDENTAL RELEASE MEASURES
Spill or Leak Procedures: Evacuate and barricade area. Ventilate area of leak or spill. Contain spill
to prevent contamination of soil, surface water or ground water; wear full protective equipment;
including respirator equipment during clean-up. If temporary control of isocyanate vapor is
required, a blanket of protein foam (available at most fire departments) may be placed over the
spill. Keep upwind of spill. Large quantities may be pumped into closed, but not sealed,
containers for disposal. Minor spills may be cleaned up by absorbing with material such as:
sawdust, vermiculite, dirt, sand, clay, cob grit, Milisorb? Avoid materials such as cement
powder. Collect material in suitable unsealed containers such as poly-lined fiber packs or
plastic drums and properly label the open containers. Do not place in sealed container.
Prolonged contact with water results in a chemical reaction, which may result in rupture of the
container. Transfer to a well-ventilated area and attempt to neutralize by adding materials such
as: mixture of 5% ammonia or 5% sodium (bi) carbonate solution; with 2% detergent and water.
If ammonia is used, use good ventilation to prevent vapor exposure. Allow to stand uncovered
for forty-eight (48) hours to let carbon dioxide escape.
SECTION 9 ?DISPOSAL CONSIDERATIONS
Disposal Method: Dispose of material in accordance with federal, state and local regulations. DO
NOT DUMP INTO ANY SEWERS, ON THE GROUND, OR INTO ANY BODY OF WATER. All
disposal methods must be in compliance with all federal, state/provincial and local laws and
regulations. Regulations may very in different locations. Waste characterizations and
compliance with applicable laws are the responsibility solely of the waste generator.
SECTION 10 ?EXPOSURE CONTROLS/PERSONAL PROTECTION
Eye Protection: Chemical type goggles and/or face shield should be worn. Vapor resistant goggles
should be worn when contact lenses are in use.

Clothing/Gloves: Permeation resistant gloves (butyl rubber, nitrile rubber, and polyvinyl alcohol).
However, please note the PVA degrades in water. Cover as much of the exposed
skin area as possible with appropriate clothing. If skin creams are used, keep the
area covered by the cream to a minimum.
Respiratory Protection: Atmospheric levels should be maintained below the exposure guideline.
When respiratory protection is required for certain operations, use an approved positive-
pressure supplied air respirator. For emergency and other conditions where the exposure
guideline may be greatly exceeded, use an approved positive-pressure self-contained breathing
apparatus or positive-pressure airline with auxiliary self-contained air supply. Exposure
guideline(s): Methylene bisphenyl isocyanate: ACGIH TLV is 0.005 ppm TWA and OSHA PEL is
0.02 ppm Ceiling. PELs are in accord with those recommended by OSHA as in the 1989
revision of PELs.
Ventilation: Local exhaust should be used to maintain levels below the TLV whenever MDI is
processed, heated, or spray applied. Standard reference sources regarding industrial
ventilation (i.e., ACGIH Industrial Ventilation) should be consulted for the guidance about
adequate ventilation.
.
SECTION 11 ?HANDLING AND STORAGE
Special Sensitivity If container is exposed to high heat (400癋, 204癈), it can be pressurized and
possibly rupture. Isocyanate reacts slowly with water to form carbon dioxide. This
gas can cause sealed containers to expand and possibly rupture.
Handling/Storing Precautions: Store in a tightly closed container to prevent moisture contamination.
in a cool, dry place. Store at temperatures between 75癋 (24癈) and
105癋 (41癈). Do not reseal of contamination is suspected. Avoid
contact with skin and eyes. Do not breathe aerosols or vapors.
