Public liability insurance holders have been told that new regulations further protecting workers from the dangers of artificial light have come into force.
Following a European Union directive to make sure that standards across the continent are harmonised, the Control of Artificial Optical Radiation at Work Regulations have been drawn up.
The Health and Safety Executive (HSE) said that workers in Britain are generally well protected from harmful sources of artificial light, including UV and lasers.
However, to help public liability insurance holders who are not already compliant, it is producing guidance to help firms manage the risks effectively.
The HSE also confirmed that common sources of light in the workplace, such as computers, photocopiers and office lights, are not affected by the new regulations.
Much like the previous Noise, Vibration and Electromagnetic Fields Directives, the new regulations will focus on risk assessment, control of exposure and instruction and training.
