When occupational exposure limit values have been established, in application of articles R. 4412-149 or R. 4412-150, for a carcinogenic, mutagenic or toxic agent for reproduction, the employer shall have technical inspections carried out by a body accredited under the conditions laid down in articles R. 4724-8 to…

If a binding occupational exposure limit value provided for in Article R. 4412-149 is exceeded, the employer shall stop work at the workstations concerned until measures have been implemented to ensure the protection of workers.

If an indicative occupational exposure limit value provided for in Article R. 4412-150 is exceeded, the employer shall carry out a risk assessment in order to determine appropriate prevention and protection measures.

The results of the measurements and the technical inspection reports are communicated by the employer to the occupational physician and to the social and economic committee. They are kept at the disposal of the Labour Inspectorate control officer, the Labour Inspectorate control officer doctor and the agents of the prevention services of the social security organisations.

Measurements and technical checks carried out in application of this paragraph must comply with the procedures and methods laid down in application of Article R. 4412-151.
