How is the work safety in HCL

Osh

Good lighting in the workplace is an important prerequisite for avoiding accidents in the workplace. In the broader sense, occupational safety is also health protection. Because according to the definition of the World Health Organization, health not only means the absence of clinical illnesses, but also includes mental and emotional integrity and general well-being. In this sense, occupational safety goes far beyond accident prevention.


Binding requirements for workplaces and their lighting apply throughout Europe. According to the EU individual directive for workplaces (89/654 / EEC)

  • Workplaces must receive as much daylight as possible and be equipped with artificial lighting that is appropriate for the safety and health of workers;
  • The lighting of the work rooms and connecting routes must be installed in such a way that the type of lighting does not pose a risk of accident for workers;
  • Workplaces in which the workers are particularly exposed to danger if the artificial lighting fails must have adequate safety lighting.

Standards and rules for occupational safety

In Germany, this EU directive was implemented by the Workplace Ordinance (ArbStättV), which was last updated in 2016. In conjunction with the Occupational Safety and Health Act (Sections 3 and 5), it obliges employers to set up workplaces in such a way that employees are not harmed to their health. The general requirements of the ArbStättV for lighting are specified in the Technical Rules for Workplaces ASR A3.4.

When planning lighting, it is advisable to observe DIN EN 12464-1 as a recognized technical rule as well as ASR 3.4 in order to meet all occupational safety and health requirements. Lighting systems must therefore be planned, installed and maintained by specialists.

Standards and rules state minimum requirements. Compliance with these does not necessarily mean that optimal lighting is achieved for certain visual tasks. For certain activities or for older employees, more light is the better choice.

Quality characteristics of the lighting

In general, a workplace is considered to be well lit if:

  • all work areas, traffic routes and break rooms are adequately lit,
  • In work areas with special visual tasks (e.g. very fine assembly work, quality control, office work), depending on the type of activity, illuminance levels of 500 to 1,500 lux can be achieved,
  • the brightness in the rooms is evenly distributed; Ceiling and walls are as bright as possible,
  • annoying glare and shadows are avoided,
  • Light sources with a suitable light color and good color rendering are used
  • and there is no flicker.

Since existing lighting systems change over time, entrepreneurs must regularly check, as part of a risk assessment, whether the requirements of ASR A3.4 are still being met.
