Polyurethane

SECTION 2: Hazards identification

EMERGENCY OVERVIEW PHYSICAL APPEARANCE: Solid rubbery like material. IMMEDIATE CONCERNS: CAUTION! Burning gives off toxic fumes. Slippery especially when wet. Metal OSHA Hazard Communication Standard: Polyurethane elastomers are fully reacted polymers forming particles which are not considered “Hazardous” as defined by OSHA Hazard Communication Standard, 29 CFR 1910.1200

Potential health effects

EYES: Not affected during normal use. SKIN: Not affected during normal use. INGESTION: Not affected during normal use. INHALATION: Inhalation of dust during machining and inhalation of vapors during hot wire cutting or branding can be irritating and lead to coughing. Fumes can contain traces of isocyanates such as MDI or TDI, carbon monoxide, oxides of nitrogen, and traces of hydrogen cyanide. SIGNS AND SYMPTOMS OF OVEREXPOSURE EYES: Not effected during normal use. SKIN Not effected during normal use. INGESTION Possible nausea and/or vomiting INHALATION: Not effected during normal use. Use NIOSHA approved respirator for any grinding or burning operation. For grinding wear a dust respirator. If generating gas by grinding, cutting, or thermal processing, wear an air - purifying respirator with organic cartridge or supplied – air respirator if ventilation is inadequate. ACUTE TOXICITY: No test data is available for acute dermal toxicity. Not expected to cause significant adverse effects if ingested. No test data is available for acute inhalation toxicity. CHRONIC: Animal studies indicate that chronic inhalation or overexposure to dust may cause inflammation of the lungs, fibrosis, and airway destruction.
