NIOSH 1979 Oct:12 pages
Working conditions at the Forest Products Division of Kerr-McGee Chemical Corporation (SIC-2491) in Texarkana, Texas were surveyed on October 9, 1979. Air samples were collected by OSHA and by the corporate industrial hygienist. Personal air samples were collected for wood treatment operators and locomotive and yard crews. Area samples were taken from the transfer and vacuum pumps used for creosote (8021394) and petroleum oil treatment, from steam line valves, and from bundles of treated ties. The company employed 60 persons, 34 of whom were production or treatment operators. Basic safety and hygiene guidelines, hygiene monitored safety surveys, preemployment examinations, and protective equipment were provided by the company. A trained first-aid person provided emergency care and local hospitals provided additional care as required. No valid measurements for creosote samples at the cylinder doors, cylinder pressure pumps, or at bundles of wood ties were recorded due to an undetermined analytical or interference error. Coal tar pitch volatiles were 0.59 and 0.23 milligrams per cubic meter at the wood tie bundles and steam line valves in the treatment building, respectively. The samples did not represent 8 hour time weighted averages.
