Potential health effects

ADDITIONAL HEALTH EFFECTS Read the datasheet for this product or the molding guide for this resin family. FIBERGLASS 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. Continued) 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. TALC Short-term over-exposure by inhalation to Talc may cause irritation of the nose, throat and lungs with cough, difficulty breathing or shortness of breath. Long-term over-exposure may lead to chronic lung disease with impaired lung function and abnormal chest x-rays. Increased susceptibility to the effects of Talc may be observed in persons with pre-existing disease of the lungs. GRAPHITE Long-term inhalation of Graphite dust or powder may cause chronic lung disorders with symptoms of lung insufficiency. Individuals with preexisting diseases of the lungs may have increased susceptibility to the toxicity of excessive exposures. 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. 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. Continued) TITANIUM DIOXIDE Short-term overexposure by inhalation to Titanium Dioxide may cause irritation of nose, throat, and lungs with cough, difficulty breathing or shortness of breath. Repeated skin contact with Titanium Dioxide may cause drying or cracking of the skin in sensitive individuals. Eye contact with Titanium Dioxide may cause eye irritation with tearing, pain or blurred vision. Results of a DuPont epidemiology study showed that employees who had been exposed to Titanium Dioxide were at no greater risk of developing lung cancer than were employees who had not been exposed to Titanium Dioxide. No pulmonary fibrosis was found in any of the employees and no association was observed between Titanium Dioxide exposure and chronic respiratory disease or x-ray abnormalities. Based on the results of this study, DuPont concludes that Titanium Dioxide will not cause lung cancer or chronic respiratory disease in humans at concentrations experienced in the workplace.
