6. Measurement external exposure

Background
If an exposure estimate is not clearly very high or very low, compared to a pre-set limit value, it may be necessary to proceed with measurements. The most commonly performedexposure measurement is of course that of exposure in the breathing zone of the worker, but also for skin exposure measurement techniques exist. In Belgium one needs to evaluate exposure, according to the KB Chemical agents, and to test against the limit value. This can, for example, be done by measurements in the breathing zone of the worker. Suchmeasurements should be done by a government-approved laboratory.
