What lighting conditions should indoor lighting meet and what lighting conditions should be in areas where work activities are carried out, such as offices?

This regulation promulgates worker safety and energy efficiency. According to Royal Decree 486/1997, of 14 April. The following minimum health and safety conditions in workplaces are included.

For example, lighting will vary and must be adapted to the characteristics of the environment and the actions carried out in that space.

In office lighting, it is most convenient to be around 3,000-4,000 degrees kelvin, the unit that measures the colour range of the light.

Lighting standards for offices and workspaces

In short, these regulations represent the minimum levels that by law must reduce health risks and, at the same time, ensure that the worker is going to have the necessary luminosity to carry out his activity.

Preponderance of natural light

It is established that natural lighting when it does not establish adequate visibility conditions must be supplemented by artificial light.

If artificial light still does not cover specific needs to perform the job correctly and without health risks, it may be supplemented by focussed light in exact areas.

Minimum lighting levels

When tasks with low visual requirements are performed, it must have a minimum of 100 lux. A place with high needs must have at least 1,000 lux.

  • Areas that are used occasionally must have a minimum of 50 lux.
  • Areas that are used throughout the working day. must have at least 100 lux.
  • Areas of punctual passage are sufficient with 25 lux.
  • Common area the minimum value is 50 lux.

Exceptions:

  • Areas where there is an appreciable risk of falls the values above the minimum lighting mentioned above must be doubled.
  • Areas in which an error of assessment endangers the worker or third parties. The same procedure shall be followed when the contrast of luminances between the target to be displayed and the background is very weak.

Distribution in work areas

In this area the lighting should be as uniform as possible, avoiding sudden variations in luminance, especially in areas where some activity is being carried out.

Therefore, when carrying out the installation, reflective areas must be taken into account and elements must be located that prevent glare from both sunlight and the high luminance artificial light we implant. Avoid the stroboscopic effect and the visual impression of intermittence.
