Worker exposures to total airborne dust, noise and light measurements were surveyed at Levi Strauss and Company (SIC-2221) in Blackstone, Virginia on December 9, 1974. The company employed 300 production and 100 indirect workers on a single daily shift. Formerly the factory was manufacturing pants but it was converting to the manufacture of outer shirts made from polyesters, rayons and cotton blended fabrics at the time of the survey. There was no medical program and industrial hygiene, and safety programs were handled at the divisional levels. No physician, nurse or clinic was provided. Health information for new employees was regularly recorded, and they were required to take a medical examination. Noise levels ranged from 72 to 93 decibels. Illumination levels in sewing areas were 42 footcandles (fc) and auxiliary illumination on sewing machines was 300fc. Airborne dust concentrations were 0.11 milligrams per cubic meter (mg/m3) with fiber diameters ranging from 3 to 20 microns. The fiber length was 727 microns. No chemicals or solvents were used. The author notes that workers exposed to 85 decibels or more for over 8 hours must have routine audiograms under the proposed OSHA standards. They recommend the use of safety glasses of optical quality to replace plastic eye shields on the button sewing machines and pulmonary function tests for workers exposed to dusts from chemically treated fabrics.
