SECTION IV HEALTH INFORMATION
EYE CONTACT: Based on the presence of component 1 this product is presumed to be moderately irritating to the eyes. Exposure may cause
corneal injury. Product vapors and/or mists may also be irritating to the eyes.
SKIN CONTACT: Based on the presence of component 2, this product is presumed to be moderately irritating to the skin. Prolonged contact may
cause damage to the skin. Based on the presence of component 1, prolonged or repeated contact may result in defatting and drying of the skin
which may result in dermatitis. Based on the presence of components 3, 4 and 5 this product may cause an allergic reaction in susceptible
individuals. Prolonged or repeated contact may cause skin irritation and may stain skin.
INHALATION: Exposure may cause irritation to the nose, throat, respiratory tract, and other mucous membranes. Based on the presence of
component 1 exposure to excessive vapor concentrations may cause signs of transient central nervous system depression (e.g., headache,
drowsiness, loss of coordination, and fatigue). Based on the presence of components 3, 4 and 5, as a result of repeated overexposure or exposure
to a single large dose, certain individuals may develop Isocyanate sensitization (chemical asthma) which will cause them to react to a later exposure
to Isocyanate at levels well below the TLV. Isocyanate sensitization may be either temporary or permanent. Once sensitized, an individual may
experience these symptoms upon exposure to dust, cold air, and other irritants. This increased lung sensitivity can persist for weeks and in severe
cases for several years. Once an individual is diagnosed as being sensitized to Isocyanate, no further exposure can be permitted. Chronic
overexposure to Isocyanate has also been reported to cause lung damage (including decrease in lung function) which may be permanent. Acute
overexposure to Isocyanates may lead to bronchitis, bronchial spasm and pulmonary edema. These effects are usually reversible. Chemical or
hypersensitive pneumonitis, with flu-like symptoms has also been reported. These symptoms can be delayed up to several hours after exposure.

INGESTION: Based on the presence of component 1 this product is presumed to be slightly toxic.
SIGNS AND SYMPTOMS: Symptoms of skin and eye irritation include pain, tearing, reddening, and swelling. Symptoms of gastrointestinal irritation
include sore throat, abdominal pain, nausea, vomiting, and diarrhea. Lung sensitization results in asthma-like symptoms: chest tightness, shortness of
breath, wheezing and coughing. These symptoms may be immediate or delayed up to several hours.
AGGRAVATED MEDICAL CONDITIONS: Pre-existing skin, eye, and respiratory disorders may be aggravated by exposure to this product. Persons
with asthmatic-type conditions, chronic bronchitis, other respiratory diseases, recurrent skin eczema, sensitization or allergies should be excluded
from working with Isocyanates.
OTHER HEALTH EFFECTS: Lung tumors have been observed in laboratory animals exposed to aerosol droplets of MDI/Polymeric MDI (6 mg/m? for
their lifetimes. Tumors occurred with respiratory irritation and lung injury. Current exposure guidelines are expected to protect against these effects.
SECTION V EMERGENCY AND FIRST AID PROCEDURES
EYE CONTACT: If irritation or redness develops, move victim away from exposure source and into fresh air. Flush eyes with water for fifteen (15)
minutes. If symptoms persist, seek medical attention. Materials containing MDI may react with the moisture of the eye forming a thick material which
may be difficult to wash from the eye.
SKIN CONTACT: Remove contaminated shoes and clothing. Cleanse affected area(s) thoroughly by washing with mild soap. If irritation or redness
develops and persists, seek medical attention.
INHALATION: If respiratory symptoms develop, move victim away from exposure source and into fresh air. If symptoms persist, seek medical
attention. If victim is not breathing, immediately begin artificial respiration. If breathing difficulties develop, oxygen should be administered by qualified
personnel. Seek immediate medical attention.
INGESTION: Dilute with liquid unless the victim is unconscious or very drowsy. If vomiting spontaneously occurs, keep the victim's head below the
hips to prevent aspiration into the lungs. Consult a physician, hospital, or poison control center and/or transport to an emergency facility immediately.
SECTION VI FIRE AND EXPLOSION HAZARDS
FLAMMABILITY CLASSIFICATION - NFPA: None
- DOT : Not regulated
FLASH POINT: Greater than 300 degrees F
EXTINGUISHING MEDIA: Carbon Dioxide, dry chemical or foam. If water is used, it should be used in very large quantity. The reaction between
water and hot Isocyanate may be vigorous.
SPECIAL FIRE FIGHTING PROCEDURES AND PRECAUTIONS: Clear area of unprotected personnel. Do not enter confined fire space without helmet,
face shield, bunker coat, gloves, rubber boots, and a positive pressure NIOSH approved self-contained breathing apparatus.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Do not reseal contaminated containers as pressure buildup may rupture them.
SECTION VII REACTIVITY
STABILITY: Unstable HAZARDOUS POLYMERIZATION: May occur
CONDITIONS AND MATERIALS TO AVOID: Avoid oxidizing materials, strong acids, strong alkalies, animes, metal compounds and surface active
materials. Avoid water as it reacts to form heat, Carbon Dioxide, and insoluble urea. The combined effect of Carbon Dioxide and heat can produce
enough pressure to rupture a closed container. The reaction with water is slow at temperatures less than 120 degrees F, but accelerated at higher
temperatures. Some reactions are violent.
HAZARDOUS DECOMPOSITION PRODUCTS: Oxides and compounds of Nitrogen. Toluene Diisocyanate, and traces of Hydrogen Cyanide.
Combustion may yield Carbon Dioxide, Carbon Monoxide, and/or incomplete combustion products. Do not breathe smoke or fumes.
SECTION VIII EMPLOYEE PROTECTION
RESPIRATORY PROTECTION: Use ventilation as required to control vapor concentrations - at least 10 air changes per hour are recommended for
good general room ventilation. If exposure exceeds the PEL/TLV, use the appropriate NIOSH approved respirator.
PROTECTIVE CLOTHING: Wear safety glasses, goggles, or a splash shield to prevent eye contact. Contact lenses should not be worn. Wear
appropriate gloves and protective clothing to prevent contact with skin and clothing.
ADDITIONAL PROTECTIVE MEASURES: Eye wash fountains and safety showers should be available for use in an emergency.
SECTION IX ENVIRONMENTAL PROTECTION
SPILL OR LEAK PROCEDURES: Evacuate and ventilate the spill area, dike spill to prevent entry into the water system, wear full protective equipment
including respiratory equipment during cleanup. LARGE SPILLS>> If temporary control of vapor is required, a blanket of protein foam (available at
most fire departments) may be placed over the spill. Large quantities may be pumped into closed, but not sealed containers for disposal. SMALL
SPILLS>> Absorb with sawdust or other absorbent material and shovel into open top containers. Do not make pressure tight. Transport to a well
ventilated area (outdoors) and treat with a neutralizing solution consisting of a mixture of water and 3-8% concentrated Ammonium Hydroxide or 5-
10% Sodium Carbonate. Add about ten (10) parts of neutralizer per part of spill while mixing. Allow to stand 48 hours allowing evolved Carbon
Dioxide to escape.
WASTE DISPOSAL: Observe all Federal, State and local regulations regarding proper disposal.
