Potential health effects

ADDITIONAL HEALTH EFFECTS Read the datasheet for this product or the molding guide for this resin family. POLYHEXAMETHYLENE ADIPAMIDE In general, skin irritation has not been produced in human patch tests with Nylon 66. However, a small percentage of subjects may respond to prolonged contact with redness of skin. Significant skin permeation, and systemic toxicity, after contact appears unlikely. There are no reports of human sensitization. If particles of Nylon 66 contact the eye, mechanical irritation with tearing, pain or blurred vision may result. FIBER GLASS The mechanical action of the sharp fibers from Fiber Glass may cause skin irritation with discomfort or rash. Eye contact with Fiber Glass particles may cause mechanical eye irritation with discomfort, tearing, or blurring of vision. Inhalation of Fiber Glass particles may cause irritation of the upper respiratory passages, with coughing and discomfort. Results from epidemiology studies suggest no causal relationship between Fiber Glass exposure and cancer. One epidemiology study does indicate a slight increase in lung cancer deaths. The evidence that fiber glass is related to these increased lung cancer deaths is considered weak. Individuals with preexisting diseases of the lungs may have increased susceptibility to the toxicity of excessive exposures. CARBON BLACK Continued) 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. 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
