Exposure by inhalation may produce eye, nose, and throat irritation. Inhalation of harmful amounts of vapor may produce mild central nervous system depression, characterized by headache, nausea, vertigo and stupor. If vomiting occurs, aspiration of the solvent into the lungs can cause chemical pneumonia. Existing respiratory disorders or skin diseases may be aggravated by exposure. Repeated or prolonged, skin contact may produce mild central nervous system depression, characterized by headache, nausea, stupor, and coma. Skin which is defatted by repeated exposure to hydrocarbon solvents is more susceptible to irritation, infection, and dermatitis. Animal studies of the effects of prolonged inhalation indicated a potential for lung damage and blood production abnormalities, some of which were fatal. Relevance of these studies to human health and the levels of exposure which might produce these results, has not been established. None of the hazardous ingredients are listed as carcinogens by IARC, NTP, & OSHA
