HSE Guide G408 “Urine Sampling for Isocyanate Exposure Measurement”
This short HSE Guide/Information sheet covers the points an employer need to have clear when using urine tests to measure isocyanate exposure.
Urine sampling indicates the success or failure of control, it does not replace air sampling.
Exposure to Isocyanate should be as low as is reasonably practicable. This includes people working nearby.
Urine tests detect levels of exposure that are well below workplace exposure limits (WELs).
