Coal Tar Pitch Volatiles
Coal tar pitch volatiles (CTPVs) are composed of various chemical vapors that become airborne during the heating of coal tar pitch. Coal tar pitch is a black or dark-brown amorphous residue produced by the distillation or heat treatment of coal tar. It is a solid at room temperature and exhibits a broad softening range instead of a defined melting temperature. Synonyms for CTPVs vary depending upon the specific compound (e.g., pyrene, phenanthrene, acridine, chrysene, anthracene and benzo(a)pyrene). [Note: National Institute for Occupational Safety and Health (NIOSH) considers coal tar, coal tar pitch, and creosote to be coal tar products.]
OSHA has not established a substance-specific standard for occupational exposure to coal tar pitch volatiles (CTPVs) however exposures are regulated under OSHA's air contaminants standard for general industry, maritime, and construction.
Provides information on how to control exposures to CTPVs as well as the exposure limits established for CTPVs and related substances.
