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 usually a thick, black or dark-brown liquid or semisolid that has a smoky odor. Other names for coal tar pitch volatiles include coal tar pitch, pitch, pitch oil, topped coal tar, coal tar pitch >351ºC (AWPI), and creosote.
Coal tar pitch volatiles are found in industry when heating of coal tar or coal tar pitch takes place. Once the pitch is heated, chemicals vaporize and may be inhaled by workers. Industries where workers are potentially exposed to CTPVs include coking, roofing, road paving, aluminum smelting, wood preserving and any others where coal tar is used.
Possible Solutions
Engineering controls are the best methods for controlling exposure to CTPVs. Engineering controls include ventilation, isolating processes involving the use of CTPVs, and, where possible, automated handling of open coal tar products. Respirators may also be worn by individuals exposed to CTPVs, and protective clothing may be used to prevent contact with products containing CTPVs. However, Personal safety equipment should be the last line of defense. |
