Section 1: Collective prevention

Reducing the risks of exposure to noise is based in particular on : 1° The use of other work processes which do not require exposure to noise or which require less exposure; 2° The choice of appropriate work equipment which, taking into account the work to be done, emits as little noise as possible; 3° In the case of work equipment used outside buildings, the possibility of providing workers with…

When the upper exposure values defined in 2° of Article R. 4431-2 are exceeded, the employer shall draw up and implement a programme of technical or work organisation measures aimed at reducing exposure to noise, taking into account, in particular, the measures mentioned in Article R. 4434-1.

Workplaces where workers are likely to be exposed to noise exceeding the upper exposure values defined in 2° of Article R. 4431-2 are appropriately signposted. These places are delimited and access is restricted where this is technically feasible and the risk of exposure justifies it.

Where the nature of the activity means that workers benefit from the use of rest areas placed under the responsibility of the employer, noise in these areas is reduced to a level compatible with their function and conditions of use.

In liaison with the occupational physician, the employer shall adapt the preventive measures provided for in this chapter to the needs of workers who are particularly sensitive to the risks arising from exposure to noise.

When, despite the preventive measures implemented in application of this chapter, exposures exceeding the exposure limit values are observed, the employer: 1° Immediately takes measures to reduce exposure to a level below these limit values; 2° Determines the causes of the excessive exposure and adapts the protection and prevention measures in order to avoid any recurrence.
