In this episode Peter Knott, occupational hygienist with GCG Consulting joins us to discuss real-time & video exposure monitoring. Real-time monitoring, in essence, is collecting exposure samples over very brief periods. On their own, they provide indications of short-term fluctuations in exposure and typically lack context. Since exposures to hazards are an event in time, workers may experience different concentration levels at different times. Video exposure monitoring synchronizes the real-time data with video recordings of workers and or environmental activities of what was going on at the time, providing an extra layer of meaning.
