Article D4163-5 of the French Labour Code

The exposure of workers with regard to the thresholds mentioned in Article D. 4163-2 is assessed after the application of collective and individual protection measures.

When the minimum duration of exposure is calculated in terms of the number of hours per year, exceeding the threshold is assessed by adding together the durations during which each of the actions takes place or during which each of the situations is observed.

When, for the application of article D. 4163-2, the employer assesses the exposure of a worker to night work, he does not take into account the nights worked in successive alternating shifts.

Article D4163-5

L’exposition des travailleurs au regard des seuils mentionnés à l’article D. 4163-2 est appréciée après application des mesures de protection collective et individuelle.


Lorsque la durée minimale d’exposition est décomptée en nombre d’heures an, le dépassement du seuil est apprécié en cumulant les durées pendant lesquelles se déroulent chacune des actions ou pendant lesquelles chacune des situations sont constatées.


Lorsque, pour l’application de l’article D. 4163-2, l’employeur apprécie l’exposition d’un travailleur au travail de nuit, il ne prend pas en compte les nuits effectuées dans les conditions du travail en équipes successives alternantes.
