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, Shipyard Employment and Construction.
Provides information about the health effects of CTPVs.
Provides references that may aid in evaluating levels of CTPVs.
Provides information on how to control exposures to CTPVs as well as the exposure limits established for CTPVs and related substances.
Provides links and references to additional resources related to CTPVs.
Workers have the right to:
- Working conditions that do not pose a risk of serious harm.
- Receive information and training (in a language and vocabulary the worker understands) about workplace hazards, methods to prevent them, and the OSHA standards that apply to their workplace.
- Review records of work-related injuries and illnesses.
- File a complaint asking OSHA to inspect their workplace if they believe there is a serious hazard or that their employer is not following OSHA’s rules. OSHA will keep all identities confidential.
- Exercise their rights under the law without retaliation, including reporting an injury or raising health and safety concerns with their employer or OSHA. If a worker has been retaliated against for using their rights, they must file a complaint with OSHA as soon as possible, but no later than 30 days.
