SECTION 2: Hazards identification

EMERGENCY OVERVIEW Form: Liquid, Paste Color: Tan Odor: Mild WARNING STATEMENTS WARNING! CAUSES EYE, SKIN, RESPIRATORY AND GASTROINTESTINAL TRACT IRRITATION. MAY BE HARMFUL IF INHALED. KEEP CHILDREN AND PETS OUT OF WORK AREAS AND AWAY FROM PRODUCT DURING USE AND HANDLING. KEEP AWAY FROM ALL SOURCES OF IGNITION. AVOID PROLONGED EXPOSURE TO HEAT. STORE PRODUCT IN TIGHTLY CLOSED CONTAINER AWAY FROM THE REACH OF CHILDREN AND PETS. Contact with this material can cause irritation to the skin, eyes and mucous membranes. Thermal decomposition or fire may produce toxic fumes and cause closed containers to rupture. Avoid breathing vapors. This product contains a respiratory and skin sensitizer. Prolonged inhalation or repeated skin contact may cause sensitization, allergic reactions, dermatitis and permanent respiratory damage. • Avoid contact with skin, eyes, and clothing. • Wash thoroughly after handling. • Keep container tightly closed when not in use and during storage.

Principle Routes of Exposure

Routes of entry for paste include eye, skin contact, and ingestion. • Routes of entry for gases include inhalation and eye contact. Acute: Based on the properties of the isocyanate compounds and considering toxicological data on similar products, this product may cause acute irritation and/or sensitization of the respiratory system leading to an asthmatic condition, wheeziness and tightness of the chest. Sensitized persons may subsequently show asthmatic symptoms when exposed to atmospheric concentrations well below the occupational exposure limit. Repeated inhalation may lead to a permanent respiratory disability. Assessment of Diphenylmethane-4,4’-diisocyanate (MDI): • Moderately toxic after short-term inhalation. • Virtually nontoxic after a single ingestion. • Virtually nontoxic after a single skin contact. • Irrespective of this assessment, substance is classified as toxic due to its carcinogenic potential. Irritation: Irritating to eyes, respiratory system and skin. Prolonged or repeated contact may result in dermatitis. Information on: Diphenylmethane-4,4’-diisocyanate (MDI) Irritating to eyes, respiratory system and skin. Sensitization: May cause sensitization by inhalation and skin contact. Information on: Diphenylmethane-4,4’-diisocyanate (MDI) The substance may cause sensitization of the respiratory tract. Sensitization after repeated skin contact is possible. Repeated Dose Toxicity: Signs and symptoms of overexposure to this product include headache, vomiting, irritation of upper respiratory tract, chest tightness, breathing difficulty, coughing, sore throat, skin irritation and/or diarrhea. This product contains Methylene Diphenyl Isocyanate (MDI) which is a potential skin sensitizer and has been shown to alter cells in certain experiments. Although inconclusive, these cellular changes may indicate potential carcinogenicity. Risk to your health depends on duration and concentration of exposure.
