Paragraph 3: Conditions for measuring dust and monitoring occupational exposure limit values

The employer shall use the same accredited body to carry out the sampling strategy, sampling and analyses. To this end, the employer shall provide it with all relevant data and, in agreement with the client, shall grant it access to the premises concerned by the operations. The body chosen shall be independent of the companies it inspects.

Individual samples are taken when workers are significantly exposed to asbestos dust inhalation, including the various operational phases.

The employer consults the occupational physician and the social and economic committee on the draft sampling strategy drawn up by the inspection body. Their opinions are forwarded by the employer to the inspection body.

Dust levels are measured using the analytical transmission electron microscopy (TEM) method.
