Abstract
Worker exposures to asbestos (1332214) were surveyed during road construction operations (SIC-1611) in National Forest lands in Northern California. The date of the survey was not reported. The survey was requested by the United States Department of Agriculture Forest Service in San Francisco. Approximately 10 workers were assigned to each road crew. Personal and area air samples were collected during rock crushing operations at Blue Ridge. No asbestos was detected in any of the samples; the OSHA standard for asbestos is 20 fibers per cubic centimeter with a ceiling concentration of 10 fibers per cubic centimeter. The author concludes that road construction workers in Northern California National Park lands probably are not exposed to an asbestos hazard, however he notes that sampling limitations precluded definite characterization of exposures. Additional sampling is recommended, along with noise exposure surveys and implementation of a hearing conservation program. The Forest Service should award grants to private contractors only when the contractors agree to abide by OSHA regulations regarding personal and area sampling.
