CHEMICAL RESISTANT URETHANE CATALYST

SECTION 2: Hazards identification

EMERGENCY OVERVIEW: DANGER! Flammable liquid and vapor. Causes skin irritation. Causes eye irritation. Harmful if inhaled. Vapor and spray mist harmful. Causes nose and throat irritation. Overexposure may cause lung damage. May cause allergic skin and respiratory reaction. Effects may be permanent.

Principle Routes of Exposure

Skin contact • Inhalation • Eye contact • Ingestion • Skin absorption Target Organs Potentially • Skin Affected by Exposure: • Respiratory Tract • Central nervous system • Eyes • Lungs • Blood

Medical Conditions Generally Aggravated by Exposure

Skin allergies. • Individuals with lung or breathing problems or prior reaction to isocyanates must not be exposed to vapor or spray mist. • Skin allergies. • Respiratory disorders, including but not limited to asthma and bronchitis. • Eye disorders. • Lung disease • Immediate (Acute) Health Effects by Route of Exposure: Inhalation Irritation: Causes nose and throat irritation. Inhalation Toxicity: Vapor harmful. May affect the brain or nervous system causing dizziness, headache or nausea. Skin Contact: Causes skin irritation. Sensitizer. Avoid exposure. If sensitized, repeated exposures will result in irritation, reddening, and rashes even for very low exposures. Eye Contact: Causes eye irritation. Ingestion Toxicity: Harmful if swallowed. Long-Term (Chronic) Health Effects: Inhalation: Isocyanate vapors or mist at concentrations above the TLV can irritate the mucous membranes in the respiratory tract causing runny nose, sore throat, coughing, chest discomfort, shortness of breath and reduced lung function. Exposure well above the TLV may lead to generally reversible bronchitis, bronchial spasm and pulmonary edema. Repeated overexposure causes sensitization in some individuals resulting in asthma-like symptoms on subsequent exposures below the TLV. Persons with preexisting bronchial hyperactivity can respond to concentrations below the TLV with similar symptoms as well as an asthma attack. NOTICE: Reports have associated repeated and prolonged occupational overexposure to solvents with permanent brain and nervous system damage. Intentional misuse by deliberately concentrating and inhaling the contents may be harmful or fatal. Skin Contact: Prolonged contact may cause an allergic skin reaction.
