ZERO VOC POLYURETHANE

SECTION 2: Hazards identification

Emergency Overview ***: Flammable liquid. Clear to amber colored liquid with solvent odor. Clear liquid with solvent odor. Harmful by inhalation, in contact with skin, and if swallowed. May cause damage to lungs, brain, and nervous system. Contact with eyes or skin causes irritation. Effects Of Overexposure - Eye Contact: Exposure to liquid, aerosol, or vapors may cause irritation, tearing, redness, and swelling accompanied by a stinging sensation. May cause conjunctivitis and corneal opacity. A pre-existing eye disease may become worse upon exposure to material or its emissions. Effects Of Overexposure - Skin Contact: Isocyanates react with skin protein and moisture and can cause irritation. Symptoms may include swelling, redness, and rash. Prolonged and repeated skin contact may cause dermatitis (allergic), drying, and defatting due to the solvent properties. Effects Of Overexposure - Inhalation: Inhalation may cause irritation to the respiratory tract (nose, mouth, mucous membranes) & acute nervous system depression characterized by the following progressive steps: headache, dizziness, staggering gait, confusion, unconsciousness, or coma. Exposure may cause drowsiness, a runny nose, sore throat, or chemical pneumonitis. As a result of previous repeated overexposures or a single large dose, certain individuals develop isocyanate sensitization (chemical asthma), which will cause them to react to a later exposure to isocyanate at levels well below the TLV. These symptoms, which can include chest tightness, wheezing, cough; shortness of breath, or asthma attack could be immediate or delayed (up to several hours after exposure). Similar to many non- specific asthmatic responses, there are reports that once sensitized an individual can experience these symptoms upon exposure to dust, cold air, or other irritants. This increased lung sensitivity can persist for weeks and in severe cases for several years. Overexposure to isocyanates has also been reported to cause lung damage (including decrease in lung function), which may be permanent. Sensitization can either be temporary or permanent. Inhalation may cause coughing, difficult breathing, and loss of consciousness. Inhalation of aerosol or skin contact may cause sensitization of susceptible persons. Exposure over the exposure limit may cause pulmonary edema, bronchitis, or bronchial spasm. Effects Of Overexposure - Ingestion: Ingestion may cause irritation to mucous membranes. May result in possible corrosive action in the mouth, stomach tissue, and digestive tract. Vomiting may cause aspiration of the solvent, resulting in chemical pneumonitis. The gastrointestinal tract lining may be damaged through the ingestion of a component. Effects Of Overexposure - Chronic Hazards: As a result of previous repeated overexposure or a single large dose, certain individuals will develop isocyanate sensitization, which will cause them to react to a later exposure of isocyanate levels well below the TLV value of isocyanates. Repeated or prolonged contact causes sensitization, asthma, and eczemas.
