Hazard - <br />Non -hazardous Carbon black is listed in OSHA 29CFR 1910.1000,Table Z-1 <br />SECTION III - PHYSICAL DATA <br />Boiling Point (OF) N.A.* Specific Gravity (H2O = 1) 1.7 - 1.9 <br />Vapor Pressure (mn Hg.) N.A.* Percent Volatile by Volume (%) N.A.* <br />Vapor Density (Air = 1) N.A.* Evaporation Rate N.A.* <br />Solubility in Water Insoluble <br />Appearance and odor Amorphous black solid, no odor <br />SECTION IV - FIRE AND EXPLOSION HAZARD DATA <br />Flammable Limits LEL UEL <br />Flash Point N.A.* Ignition in air above 600°F N.A.* N.A.* <br />Extinguishing Media: Copious Water <br />Special Fire Fighting Procedures: Normal fog or nozzle jet application <br />and/or exclusion of air. <br />Unusual Fire and Ex -plosion Hazards: Carbon monoxide and carbon dioxide are <br />Products of combustion. Use appropriate respirator for protection <br />against possible exposure to Co or CO2. It may not be obvious that <br />the carbon black. is burning unless the material is stirred and sparks are <br />apparent. <br />SECTION V - HEALTH HAZARD DATA <br />Effects of overex-posure <br />Acute: None known other than possible temporary discomfort due to <br />inhalation of dust concentrations above the Permissible ExDosure <br />Limit. <br />Chronic: None recognized. Carbon black contains trace amounts of adsorbed <br />polynuclear aromatic compounds (PNA) . In non -adsorbed form, some <br />PNA's have been found to be carcinogens in certain studies. 'No <br />carcinogenic effect has been found in animals or humans due '._o <br />exposure to carbon black. Carbon black is not considered a <br />potential carcinogen by IARC, OSHA or NTP. <br />Epidemiological studies of workers in the carbon black producing <br />industry have shown no significant health effects due to occupa- <br />tional exposure to carbon black. <br />-22- <br />
