A Crew Exposure Study. Volume 1. Offshore
Abstract
The objective of this project was to implement the Phase I test plan for characterizing occupational exposures of offshore facility workers to chemical substances and selected physical agents. This report documents the measurement and monitoring data that were collected during a 7-day period on drilling and production facilities. Respirable and total dust/fume exposures were monitored during mud makeup operations, welding and rust/paint chipping. Sound pressure level contour maps were generated for seven platforms and two rigs. Personal noise dosimetry data were collected during drilling and tripping, addition of drilling fluid chemicals and maintenance/repair activities. Occupational exposures to dusts and fumes were evaluated relative to ACGIH exposure limits. Noise dosimetry data were interpreted relative to the exposure guidelines in USCG Navigation and Vessel Inspection Circular (NVC 12-82). The study concluded that exposures to the airborne substances were acceptable for the materials and operations that existed during the 7-day observation. Additional monitoring would be needed to assess other drilling muds and mud chemicals that were not observed. Noise data obtained on this study indicate the need for initiating or maintaining hearing conservation programs. (Author)
