Lighting

Orientation lighting must be described in the Health and Safety Plan. Both this document and the tender documentation must state which part of the lighting individual contractors are responsible for.

General

Place contacts as close to the entrance as possible. If orientation lighting is necessary but has not been installed in working areas or rooms, it must be possible to switch on work lighting at the entrance to the area or room.

In the locations where the lights must always stay on, you must position the contacts so that you do not turn out all the lights by mistake. Where necessary, use a key switch.

Distribute the lighting over as many electrical groups as possible so that a single fuse cannot turn out the lights over large areas.

Consider whether emergency lighting is required anywhere.

Areas and rooms with insufficient lighting must be cordoned off or marked out.
Premises without light must be cordoned off if there is a risk of anyone falling or otherwise being injured. Other rooms or areas which have insufficient lighting can be either cordoned off or marked out.

Provide a cabinet containing fuses and lamps in a readily accessible location.

Non-dazzle lighting

Lighting must never dazzle, cause reflections or cause uncomfortable heat. Always apply light from at least 2 sides. This helps to prevent deep shadows.

Risk of fire and risk of electrical accidents

Keep fittings clean and in good condition. Remember to put back protective grilles when you have replaced bulbs and lamps.

Fittings which are to be used in the open must be designed for the purpose. Defective fittings may cause fire or electrical accidents.

Bear in mind the positioning of lamps. If they have a high surface temperature, they may start a fire. Therefore, never place them on the floor; there is a major risk there of them coming into contact with highly inflammable materials.

Lamps which do not have double protection must have earth connections at their connection points. Remember to use transformer plugs or to replace e.g. German and Swedish plugs.

Orientation lighting

Orientation lighting is the lighting necessary to allow people and vehicles to move safely around the building site. This must be at a strength of at least 25 lux.

Work lighting

Work lighting is the lighting necessary to allow employees to do their jobs safely. The light must be suited to the tasks being performed.

Measurement and assessment of lighting

It is possible to measure the strength of lighting using a luxmeter. The unit lux is a measure of how much light strikes a given surface.

Be aware that the older a light source is, the less light it gives off. Therefore, it is a good idea to choose higher lux values than those stated here.
