Discover the standards and regulations dedicated to air filtration in industry

The risks posed to the health of operators via the work environment are such that air quality is governed by numerous regulations. Whether general or specific for each activity, they guide us on how to preserve this precious commodity: air.

Qualité de l'air, une obligation de l'employeur

Air quality, an employer's obligation

Ventilation and aeration of the workplace play a crucial role in reducing the concentration of all contaminants in the work environment and exposure time, as well as protecting the health of workers. This will enable all employees to breathe in air that is not harmful to their health. The employer must renew the air to maintain the purity of the atmosphere, prevent temperature rise, unpleasant odours and condensation, and extract contaminants.

What French law states

The main regulation concerning air quality is set out in the French Labour Code (Article R4412-149) which specifies the occupational exposure limit values for contaminants present in the workplace atmosphere and in the worker breathing zone.

In enclosed premises where workers are required to spend time, the air must be renewed in order to:

  • Maintain the purity of the atmosphere so as to protect the health of workers (collective protection).
  • Prevent excessive temperature rise, unpleasant odours and condensation.

The employer must maintain all installations in good working order and ensure they are inspected regularly (French Labour Code, Article R. 4222-20 et seq.).

Read the legislation on ventilation in the French Labour code

There are many directives for each activity and they prescribe specific prevention measures

Traiter les poussières de bois réglementations

Wood dust

Workers exposed to wood dust are included on the list of carcinogenic processes (Order of 5 January 1993, amended).

Le Chrome VI, Chrome hexavalent et ses composés réglementation

Chromium VI or hexavalent chromium and its compounds

In a work environment, inhalation is the main route of exposure to chromium VI. It is considered carcinogenic by the CIRC (WHO cancer research agency) (Group 1).

Traiter les poussières minérales, végétales ou animale réglementation

Dust of mineral, vegetable or animal origin

This may come from the raw materials used during the processing of finished or semi-finished products, or during demolition and cleaning operations.

European directives

Emissions of atmospheric contaminants in the industrial sector are regulated by the directive of 2010 on industrial emissions (Directive IED 2010/45/EU), among others. The aim of this Directive, called the IED Directive, is to protect the environment through the integrated prevention and control of pollution from a wide range of industrial activities.

Explosive atmosphere regulation (ATEX Directive: ISO/IEC 80079-34: 2018)

Prevention of the risk of explosion in the workplace is subject to a specific regulation. The ATEX Directive 94/9/EC has been transposed into French law (Articles R.4216-31 and R. 4227-54 of the French Labour Code). 

It is the employer’s duty to apply the general principles of prevention and to assess the risk of explosion.

In addition to the provisions of the French Labour Code, when an establishment is subject to the legislation of Installations Classified for the Protection of the Environment (ICPE), it must comply with the provisions of Title I.
