Polyurethane elastomers are fully reacted polymers forming Articles which are not considered hazardous under osha’s Criteria 29 cfr 1910.1200. However, hazardous dusts, vapors, gases, or fumes may be released by mechanical or thermal processing, or by thermal decomposition.
Section 3: Hazard Identification
Emergency Overview
Acute:
Fumes from hot wire cutting can be irritating and lead to coughing. These fumes could contain traces of tdi, mdi, other isocyanates, and/or curatives. Skin or airborne exposure to isocyanates may produce an asthma-like lung sensitization, with shortness of breath, wheezing or cough, which may occur after re-exposure to very low levels.
Skin contact with some polyurethane products may result in skin sensitization or an asthma-like lung sensitization.
Chronic:
Animal studies indicate that chronic inhalation or overexposure of dusts may cause inflammation of the lungs, fibrosis, and airway destruction.
Severe Immediate Hazards:
Dusts from grinding operations may aggravate existing lung disorders when proper protection is not used.
Potential Health Effects:
Routes of Exposure: x Skin x Inhalation o Ingestion
Lengths of Exposure: o Single x Repeated x Lifetime
Severity of Effect: o Mild o Moderate x Severe
Target Organs: o Liver o Kidney x Lung x Skin o _________
Effects/Symptoms:
Seeacuteandchroniceffects in Emergency Overview.
Carcinogenity: Cured polyurethane is not listed as a carcinogen.
Section 4: First Aid Procedures
Procedures: Flush eyes with water if dust from grinding causes irritation.
Note to Physicians (if available):None
Section 5: Fire Fighting Measures
Flammable Properties
Flash Point: Not Applicable
Flammable Limits: LEL: Not Applicable UEL: Not Applicable
Dusts from processing operations may be combustible.
Extinguishing Media: Water, dry chemical, foam, or carbon dioxide.
Fire Fighting Instructions: Evacuate non-emergency personnel to a safe area. Firefighters should use selfcontained breathing apparatus. Avoid breathing smoke, fumes, and decomposition products. Use water spray to quench smoldering elastomers. Product may melt after ignition, to form flammable liquids. Burning produces intense heat, dense smoke, and toxic gases, such as isocyanates, carbon monoxide, oxides of nitrogen, and traces of hydrogen cyanide. Do not breathe smoke. Smoke released, even after fire is out, may contain high concentrations of isocyanates hundreds of feet away. Do not remove self-contained breathing apparatus until smoke is gone and area is completely ventilated with clean air.
Section 6: Accidental Release Measures
Safeguards (Personal):None
Spill Clean Up: Pick up and handle as any other solid material.
Section 7: Handling and Storage
Handling: Cutting elastomer by hot wire or hot branding, or other thermal processing can form decomposition products. Local exhaust ventilation should be used to remove any fumes. If isocyanates or curatives are emitted, ventilation must be sufficient to ensure levels below the TLV for TDI (0.005 PPM TWA/0.02 PPM STEL), MDI (0.005 PPM TWA), other isocyanates, or curatives. Also, see respiratory protection below.
Storage: Store elastomers in areas equipped with sprinkler systems. Store away from sparks, flames, or other ignition sources.
Section 8: Exposure Controls, Personal Protection
Engineering Controls: Local exhaust recommended for thermal processing operations, as required to reduce dust, gas, and vapor fume exposure below OSHA levels.
Personal Protective Equipment
Eye/Face Protection: None required in normal use. For grinding operations, use safety goggles, and face shield.
Skin Protection: None required in normal use.
Respiratory Protection (specify type): Use NIOSH approved respirator. For grinding operations – wear a dust respirator. If generating gas, vapor, and fumes from hot wire, hot knife, or other thermal processing operations – wear an air-purifying respirator with organic cartridge or supplied-air respirator if ventilation is inadequate.
General Protection:None required.
