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 eye irritation. May cause slight temporary corneal injury.
Skin Contact: Prolonged contact may cause moderate skin irritation with local redness. Material may
stick to skin causing irritation upon removal. 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. May cause central nervous system depression. Symptoms of
excessive exposure may be anesthetic or narcotic effects; dizziness and drowsiness may be
observed. Excessive exposure may increase sensitivity to epinephrine and increase myocardial
irritability (irregular heartbeats). Decreased lung function has been associated with overexposure to
isocyanates.
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.
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.
Contains component(s) which have been reported to cause effects on the following organs in animals:
Kidney. Liver. Bone marrow. Contains a component which is reported to be a weak
organophosphate-type cholinesterase inhibitor. Excessive exposure may produce organophosphate
type cholinesterase inhibition. Signs and symptoms of excessive exposure may be headache,
dizziness, incoordination, muscle twitching, tremors, nausea, abdominal cramps, diarrhea, sweating,
pinpoint pupils, blurred vision, salivation, tearing, tightness in chest, excessive urination, convulsions.
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.
