Hazard mapping with direct reading instruments from facilities with high and low temporal variability
MetadataShow full item record
The purpose of this study was to develop novel sampling techniques employing relatively lower-cost direct-reading instruments (DRIs, instruments that report hazard intensity at near real-time resolution) for hazard mapping. Normally, personal sampling equipment worn by workers is used to determine personal exposure (time-weighted average) to a hazard for comparison with an occupational exposure limit (OEL). However, time-weighted average methods give the industrial hygienists (IH) no information on the spatial or temporal variability of the exposures. Hazard maps have been suggested as a way to ...
