Industrial Hygiene Survey Report at Reynolds Aluminum Company, Longview, Washington, August 28-30, 1978

摘要

A survey to determine exposure to selected polynuclear-aromatic-hydrocarbons (PAH) was conducted at Reynolds Aluminum Company (SIC-3334), Primary Metals Division in Longview, Washington on August 28-30, 1978. A total of 1,030 production employees were located at the north and south facilities. Particulates in samples for total particulates, chrysene, pyrene, fluoranthene, benz(a)anthracene, and benzo(a)pyrene ranged from less than 0.04 to 0.83 milligrams per cubic meter, and less than 0.35 to 9.40, less than 0.28 to about less than 3.5, less than 0.06 to 0.88, less than 0.20 to 5.20, and 0.35 to 4.90 micrograms per cubic meter, respectively, in both facilities. Corresponding concentration ranges detected in vapor form were 0.06 to 0.21 milligrams per cubic meter and less than 0.14 to 1.30, less than 0.36 to 6.90, 1.40 to 12.00, less than 0.13 to 1.20, and less than 0.10 to 1.50 micrograms per cubic meter, respectively. Total nuisance dust and respirable dust concentrations ranged from 1.33 to 5.86 and 0.15 to 5.11 milligrams per cubic meter, respectively.
