Abstract
Continuous recordings of time, position and exposure can be meshed to form a powerful new tool in exposure assessment, which can result in more accurate task-based exposure assessments. Using position as a surrogate for task leads to more accurate records than are obtained from worker recollection, and at least as accurate as records from observers. Positioning systems are particularly useful for highly mobile workers in the outdoor environment. NIOSH in the USA has developed an outdoor positioning system based on GPS technology, that can be used with a variety of real-time monitors, including multi-gas monitors, photoionization detectors for vapors, aerosol photomoters, noise dosimeters and heat-stress monitors. The technology has been tested in a range of outdoor environments, for example with road construction, on coast guard boats, and in park areas with rugged terrain. IOSH in Taiwan has developed a small infra-red sensor system for indoor use based on conventional remote electronic connections. This system can be used alone, and with a proprietary metal-oxide semiconductor sensor that has been shown to have very rapid response to many gases and vapors. Both outdoor and indoor technologies are patented and are available for license.
