"KALREZ" KLR6375

Potential health effects

ADDITIONAL HEALTH EFFECTS No data available for cured perfluoroelastomer. INHALATION Inhalation of fumes from overheating or burning "KALREZ", or from smoking tobacco or cigarettes contaminated with polymer may cause polymer fume fever, a flu-like illness with chills and fever. Symptoms may not occur for several hours after exposure, and go away in 24-48 hours even in absence of treatment. Inhalation of low concentrations of hydrogen fluoride can initially include symptoms of choking, coughing, and severe eye, nose and throat irritation. Possibly followed after a symptomless period of 1 to 2 days by fever, chills, difficulty in breathing, cyanosis, and pulmonary edema. Acute or chronic overexposure to HF can injure the liver and kidneys. Individuals with preexisting diseases of the lungs may have increased susceptibility to the toxicity of excessive exposures to hydrogen fluoride. PERFLUOROALKYPOLYETHER of overexposure by skin contact may include skin irritation with discomfort or rash. Eye contact may cause irritation with discomfort, tearing or blurring of vision. Inhalation of smoke or fumes from burning material may cause polymer fume fever, a flu-like illness with fever, chills, and sometimes cough, of approximately 24-48 hours duration. Smokers should avoid contamination of tobacco products, and should wash their hands before smoking. Otherwise no acceptable information is available to confidently predict the effects of excessive human exposure to this compound. CARBON BLACK Immediate effects of overexposure to Carbon Black by inhalation may include irritation of the nose, throat, and lungs with cough, difficulty breathing or shortness of breath. If particles from Carbon Black contact the eye, mechanical irritation with tearing, pain or blurred vision may result. Significant skin permeation, and systemic toxicity, after contact with Carbon Black appears unlikely. There are no reports of human sensitization. Continued) Epidemiologic studies demonstrate no significant risk of human cancer from exposure to Carbon Black. While some reports cite an increased incidence of pulmonary abnormalities, such as decreased pulmonary function and radiological changes among Carbon Black workers, other reports show no correlation between exposure and effects on pulmonary function or disease. Increased susceptibility to the effects of Carbon Black may be observed in persons with pre-existing disease of the lungs. Carcinogenicity Information The following components are listed by IARC, NTP, OSHA or ACGIH as carcinogens.
