What are the risks of incorrect lighting in the workplace? (copy 1)

Inadequate lighting significantly increases the risk of accidents. In a too dark work environment, potential sources of danger are perceived more badly and the typical SRS accidents (tripping, slipping and falling accidents) are quickly the unpleasant result.

In case of poor visibility, concentration and performance can be reduced. Physical discomfort, such as burning eyes or headaches, not only affects well-being, but also has a negative impact on the frequency of errors in the work process.

Caution: Lighting that is too bright can also lead to problems when employees are blinded by unsuitable or misaligned luminaires.

Our infographics gives you a quick overview of the negative effects of wrong lighting in the workplace:

Who is responsible for lighting in the workplace? (copy 1)

The employer is expected to set up workplaces and workplaces in such a way that there are no health hazards for the employees. This also includes an adequate lighting for the individual visual tasks.

Within the scope of a hazard assessment, it is necessary to determine and regularly check whether the workstations are suitably illuminated during operation. This can be determined with a corresponding measuring device (luxmeter).

Is lighting sufficient with daylight? (copy 1)

Is lighting sufficient with daylight?

Daylight increases the well-being, so it is a not negligible aspect in the lighting of workplaces. Workplaces, for example in office areas, should be set up as remote as possible.

In practice, however, daylight is not always available in sufficient time and place. An additional artificial lighting is therefore usually required. In our Online shop you will find wall and ceiling lights, tube lights, emergency lights, hand lamps, headlights, flashlights, machine lighting, working lights, magnifying lamps and emergency lighting.

Many products are also available in ex-protected design.

What do I need to know about setting up, maintaining and installing lighting systems? (copy 1)

 "The same light for all" is not an adequate solution in workplaces. Because it depends on the individual visual task, how much light is needed in the workplace. A general lighting system ensures a uniform illumination of the entire work area, but does not take into account the lighting requirements of individual room sections or workstations. Appendix 1 of the ASR A3.4 specifies the minimum values ​​to be observed for the illuminances and color reproduction indices for the different areas.

Table: Recommended lighting levels:

At no point in the area of the workplace may the temperature be 0.6 times lower than the average illuminance. The lowest value must not be within the range of the main vision task.

If minimum illuminance levels of more than 500 lux are stipulated, they do not necessarily have to be achieved at the entire workplace, but only at the partial surfaces relevant to the visual task. Partial lighting can be used, for example, when there is a special visual task (working with small parts, short observation periods) or when adaptation to the individual's vision of the employees is necessary. Here, for example, the use of additional machine lighting or workplace lighting is recommended.

It is advisable to plan and maintain lighting systems by a qualified person. After the installation of the lighting system and the necessary firing time, compliance with the legal requirements should be checked by means of control measurements.

Periodic testing and maintenance is also necessary to correct any changes in the lighting parameters, as well as to correct any contamination or damage.
