Abstract
An industrial hygiene survey was carried out to determine the exposure to hexachlorobenzene (118741) (HCB) of 26 employees at a facility engaged in the manufacturing of pentachlorophenol (PCP) by a direct batch type process. Analysis of 24 of 54 personal breathing zone samples which had detectable levels of HCB revealed that the workers were exposed to concentrations of HCB ranging from 0.0008 to throughout the manufacturing facility, which had detectable concentrations of the product, ranged from 0.0003 to 0.63mg/m3, while the concentrations recorded in surface wipe samples ranged from less than 0.1 to 3.7 micrograms per wipe. Handymen had the highest HCB exposures and the block pulling and storage areas, where the handymen spent most of their time, presented the highest concentrations of HCB in the air (0.0006 to 0.45mg/m3 and 0.0006 to for the PCP operator position were free of HCB. The author concludes that the detectable concentrations of HCB associated with the production of PCP indicate that workers are potentially exposed to the agent both by inhalation and dermal contact.
