Hazards of product:
WARNING! May cause allergic skin reaction. May cause allergic respiratory reaction.
May cause lung injury. May cause eye irritation. May cause skin irritation. Vapor
reduces oxygen available for breathing. May cause central nervous system effects.
May cause anesthetic effects. May cause respiratory tract irritation. Toxic fumes may
be released in fire situations. May react with water. Elevated temperatures can cause
hazardous polymerization. Material reacts slowly with water, releasing carbon dioxide
which can cause pressure buildup and rupture of closed containers. Elevated
temperatures accelerate this reaction. Isolate area. Keep upwind of spill. Stay out of
low areas. Contents under pressure.
OSHA Hazard Communication Standard
This product is a “Hazardous Chemical” as defined by the OSHA Hazard Communication Standard, 29
CFR 1910.1200.
Potential Health Effects
Eye Contact: May cause moderate eye irritation. May cause slight temporary corneal injury.
Skin Contact: Prolonged contact may cause skin irritation with local redness. May stain skin.
Skin Absorption: Prolonged skin contact is unlikely to result in absorption of harmful amounts.
Skin Sensitization: Skin contact may cause an allergic skin reaction. Animal studies have shown that
skin contact with isocyanates may play a role in respiratory sensitization.
Inhalation: In confined or poorly ventilated areas, vapor can easily accumulate and can cause
unconsciousness and death due to displacement of oxygen. Excessive exposure may cause irritation
to upper respiratory tract (nose and throat) and lungs. May cause pulmonary edema (fluid in the
lungs.) Effects may be delayed. Decreased lung function has been associated with overexposure to
isocyanates. Excessive exposure may increase sensitivity to epinephrine and increase myocardial
irritability (irregular heartbeats). May cause central nervous system effects. Symptoms of excessive
exposure may be anesthetic or narcotic effects; dizziness and drowsiness may be observed.
Respiratory Sensitization: May cause allergic respiratory response. MDI concentrations below the
exposure guidelines may cause allergic respiratory reactions in individuals already sensitized.
Asthma-like symptoms may include coughing, difficult breathing and a feeling of tightness in the chest.
Occasionally, breathing difficulties may be life threatening.
Ingestion: Low toxicity if swallowed. Small amounts swallowed incidentally as a result of normal
handling operations are not likely to cause injury; however, swallowing larger amounts may cause
injury. Observations in animals include: Gastrointestinal irritation.
Aspiration hazard: Based on physical properties, not likely to be an aspiration hazard.
Effects of Repeated Exposure: Tissue injury in the upper respiratory tract and lungs has been
observed in laboratory animals after repeated excessive exposures to MDI/polymeric MDI aerosols.
Cancer Information: Lung tumors have been observed in laboratory animals exposed to respirable
aerosol droplets of MDI/Polymeric MDI (6 mg/m3) for their lifetime. Tumors occurred concurrently with
respiratory irritation and lung injury. Current exposure guidelines are expected to protect against these
effects reported for MDI.
Birth Defects/Developmental Effects: In laboratory animals, MDI/polymeric MDI did not cause birth
defects; other fetal effects occurred only at high doses which were toxic to the mother. Contains
component(s) which did not cause birth defects in animals; other fetal effects occurred only at doses
toxic to the mother.
