Abstract
Abstract This pilot study is the application of a task-based sampling method used to characterize exposures on a highway construction project. The study developed methods to conduct occupational hygiene exposure assessment during building of a highway interchange. The sampling strategy was planned based on three sources of information: budgetary breakdown of the project, observations by an industrial hygienist, and interviews with the workers and the contractor at the site. This information permitted the partition of road construction work into three components: (1) stage, (2) operation, and (3) specific task. A method to develop a sampling plan was designed based on this analysis. The pilot study measured exposures to noise, dust, respirable silica, and asphalt fumes on 25 operating engineers and laborers working on the road construction project. Noise exposure measurements were made in three stages during three operations. Full-shift noise data were collected on operating engineers using different types...
