CAS Number 4,4’-DIPHENYLMETHANE DIISOCYANATE 101-68-8 *** ALL Ingredients in this product are listed in the T.S.C.A. Inventory SECTION III - HAZARDS IDENTIFICATION HEALTH HAZARD INFORMATION: EYE CONTACT: MAY CAUSE EYE IRRITATION. CORNEAL DAMAGE POSSIBLE. SKIN CONTACT: MAY CAUSE IRRITATION. PROLONGED OR REPEATED CONTACT MAY CAUSE RASH, REDDENING, SWELLING, AND IN SOME CASES, SKIN SENSITIZATION. INHALATION: AT ROOM TEMPERATURE VAPORS ARE MINIMAL DUE TO LOW VAPOR PRESSURE. HOWEVER, HEATING OR SPRAYING MAY GENERATE VAPOR CONCENTRATIONS SUFFICIENT TO CAUSE IRRITATION. EXCESSIVE EXPOSURE MAY CAUSE IRRITATION OF THE EYES, UPPER RESPIRATORY TRACT, AND LUNGS. MAY CAUSE RESPIRATORY SENSITIZATION IN SUSCEPTIBLE INDIVIDUALS. MDI CONCENTRATIONS BELOW THE EXPOSURE GUIDELINES MAY CAUSE ALLERGIC RESPIRATORY REACTIONS IN INDIVIDUALS ALREADY SENSITIZED. SYMPTOMS MAY INCLUDE COUGHING, DIFFICULT BREATHING AND A FEELING OF TIGHTNESS IN THE CHEST. EFFECTS MAY BE DELAYED. IMPAIRED LUNG FUNCTION (DECREASED VENTILATORY CAPACITY) HAS BEEN ASSOCIATED WITH OVEREXPOSURE TO ISOCYANATES. INGESTION: MAY CAUSE IRRITATION AND CORROSIVE ACTION IN THE MOUTH, STOMACH TISSUE AND DIGESTIVE TRACT. SYMPTOMS CAN INCLUDE SORE THROAT, ABDOMINAL PAIN, NAUSEA, VOMITING AND DIARRHEA. OTHER HEALTH INFORMATION (POLYMERIC MDI CAS 101-68-8): TISSUE INJURY IN THE UPPER RESPIRATORY TRACT AND LUNGS HAS BEEN OBSERVED IN LABORATORY ANIMALS AFTER REPEATED EXCESSIVE EXPOSURES TO MDI/POLYMERIC MDI AEROSOLS. LUNG TUMORS HAVE BEEN OBSERVED IN LABORATORY ANIMALS EXPOSED TO AEROSOL DROPLETS OF MDI/POLYMERIC MDI 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. IN LABORATORY ANIMALS, MDI/POLYMERIC MDI DID NOT PRODUCE BIRTH DEFECTS; OTHER FETAL EFFECTS OCCURRED ONLY AT HIGH DOSES WHICH WERE TOXIC TO THE MOTHER. ANIMAL TESTS HAVE ALSO INDICATED THAT RESPIRATORY SENSITIZATION CAN RESULT FROM SKIN CONTACT WITH MDI. USE SKIN PROTECTION.
