Professional lighting: safety and risk prevention

In addition to the search for greater energy efficiency, redesigning and optimizing lighting in the workplace can help to improve safety and prevent potential risks to people’s health and well-being.

The lighting of premises and professional lighting must at least comply with local regulations and in particular meet the legal requirements for safety at work, which can vary not only according to the sector of activity (industry, tertiary sector, agricultural sector, etc.)

An illumination adapted to the workplace must promote a work environment that is as comfortable as possible for the individual, avoiding complicated postures and unnecessary and exhausting visual efforts.

Natural lighting is always recommended by means of bay windows on the outside and at eye level. There are specific provisions for incompatible activities (eg supermarkets, photographic laboratories, warehouses, industrial lighting, etc.).

Professional lighting safety not only regulates the illumination of the workplace, but also covers all traffic and / or works areas inside and outside the company (roadway, Access to premises, emergency exits …) by setting minimum illumination values ​​to be respected for each type of space. These minimum values ​​are expressed in lux (measurement of luminous flux per unit area) and can be monitored by the labor inspectorate. In this respect, Airfal offers different types of emergency lighting and emergency kits.

In order to ensure that constant lighting is maintained, it is necessary to evaluate the variation in the intensity of natural lighting during the day and to ensure a sufficiently regular maintenance of the equipment. In the case of rooms with low or no natural lighting (basements ..), access to the lighting controls must be facilitated to the maximum by appropriate signaling.

The minimum values ​​required are also differentiated according to the degree of precision and difficulty of the work required at the workplace. They require complementing the general illumination with localized lighting specifically adapted to the workstation, the type of work required and the visual capacity of the person. For example, when it comes to industrial lighting, it will be necessary to use a suitable luminaire.

Differences in lighting levels within the same space or contiguous spaces are also regulated and must be limited (illumination ratio which measures the differences in light received and the luminance ratio for the light emitted by reflective surfaces ) To prevent glare and visual fatigue. Depending on the sector of activity, the color rendering index of the illumination equipment must also be taken into account. This international index (Ra) makes it possible to evaluate the comfort quality of the light emitted.

Finally, all preventive measures must be taken to protect people from the possible thermal variations (increase in temperature, burns) produced by the lighting equipment. In the case of rooms with low or no natural lighting (basements ..), access to the lighting controls must be eased with appropriate signals.
