Health hazards

Arise from Inhalation of fumes consisting of - ultra-fine, low-molecular-weight fluoropolymer particles - carbonyl fluoride COF2 (CAS 353-50-4) [500 0С (932 0F) - 600 0С (11100 F)] - hydrogen fluoride HF (CAS 7664-39-3) [400 0С (752 0F)] - carbon dioxide CO2 (CAS 124-38-9) [> 650 0С (1200 0F)] - carbon monoxide СО (СAS 630-08-0) [> 650 0С (1200 0F)] - perfluoroisobutylene C4F8 (CAS 382-21-8) [475 0С (887 0F)] - hexafluoropropylene C3F6 (CAS 116-15-4) [460 0С (860 0F)] – - tetrafluoroethylene C2F4 (CAS 116-14-3) [450 0С (842 0F)] from overheating [> 260 0C (500 0F)] or burning 2.2.3 Symptoms: If inhaled: Inhalation of ultra-fine, low-molecular-weight fluoropolymer particles provokes signs/symptoms of <Polymer Fume Fever = PFF> of 24 hours duration: chest pain or tightness, shortness of breath, cough, malaise, muscle aches, increased heart rate, fever, chills, sweats, nausea and headache. Inhalation of low concentrations of Hydrogen Fluoride HF and Carbonyl fluoride COF2 can initially include symptoms of choking, lung irritation effects with coughing, nose and throat irritation. After a symptom less period of 1 to 2 days they are followed by fever, chills, difficulty in breathing, cyanosis and pulmonary edema. Acute or chronic overexposure to HF can injure liver and kidneys. Inhalation of Perfluoroisobutylene PFIB causes severe symptoms of pulmonary edema with wheezing, difficulty in breathing, coughing up sputum and bluish discoloration of the skin. Coughing and chest pain may occur initially. Overexposure may cause death [LC50, (Oral-Rat) = 1,05 ppm/2hrs] On contact with eyes: Vapors from heated material may cause eye irritation. Signs/symptoms may include redness, swelling, pain and blurred or hazy vision. Eye contact with Carbonyl fluoride COF2 leads to eye corrosion with corneal ulceration On skin contact: Carbonyl fluoride COF2 provokes skin irritation or rash. Thermal burns : Signs/symptoms may include severe pain, redness and swelling, tissue destruction If ingestion: Not expected to be a hazard in normal industrial use and if ingested. Data about human body sensibilization are not available. The product is not classified as a human carcinogen. General rating: Group 3. In case of spill, the material forms a dangerously slippery surface
