Potential health effects

ADDITIONAL HEALTH EFFECTS ACUTE OR IMMEDIATE EFFECTS: ROUTES OF ENTRY AND SYMPTOMS INGESTION: Not a probable route of exposure. SKIN: Contact with maleic anhydride vapour will cause severe skin irritation. Contact with resin may cause mild irritation of skin. EYE: Contact with maleic anhydride vapour will cause severe eye irritation. Contact with resin may cause mild irritation of eyes. INHALATION: Polymer is not respirable as sold. At processing temperatures above 290 C (554 F), fumes irritating to the eyes, nose and throat may be evolved. Exposure may result in redness, itching and tearing of the eyes and soreness in the nose and throat together with coughing. Contact with maleic anhydride vapour will cause severe nose and throat irritation. This copolymer may produce volatile skin, eye or respiratory irritants on thermal processing. The atmosphere and dust contained in the package may cause similar irritation. Overexposure may cause allergic respiratory reaction. Avoid inhalation of stagnant air in closed container of polymer and contact with dust on container lid.

Medical Conditions Generally Aggravated by Exposure

None known MALEIC ANHYDRIDE (RESIDUAL) Skin contact with Maleic Anhydride may cause skin burns or ulceration. Significant skin permeation, and systemic toxicity, after contact appears unlikely. There are inconclusive or unverified reports of human sensitization. Eye contact with Maleic Anhydride may cause eye corrosion with corneal or conjunctival ulceration. Exposure to the vapors may cause tearing, blurring of vision, sensitivity to light, or inflammation of the eyelids. Inhalation of Maleic Anhydride may cause headaches, nausea, irritation or ulceration of the upper respiratory passages; workers have reported nasal irritation after a one minute exposure to 1.5 ppm. This compound may cause asthma-like reactions with shortness of breath, wheezing, or cough. Higher overexposures may cause pulmonary edema (body fluid in the lungs) with cough, wheezing, abnormal lung sounds, possibly progressing to severe shortness of breath and bluish discoloration of the skin. Symptoms may be delayed. Prompt medical attention is required. Ingestion of Maleic Anhydride may cause severe burns of the mouth and tissues of the upper gastrointestinal tract with severe pain, bleeding, vomiting, diarrhea and collapse of blood pressure. Prolonged or gross overexposures may cause abnormal kidney function as detected by laboratory tests. Carcinogenicity Information None of the components present in this material at concentrations equal to or greater than 0.1% are listed by IARC, NTP, OSHA or ACGIH as a carcinogen. ----------------------------------------------------------------------
