2.3 Lighting:
Lighting should be sufficient to enable people to work and move about safely.

If necessary, local lighting should be provided at individual workstations and at places of particular risk such as crossing points on traffic routes.

Lighting and light fittings should not create any hazard.

Automatic emergency lighting, powered by an independent source, should be provided where sudden loss of light would create a risk.

2.4 Cleanliness and waste materials:
Every workplace and the furniture, furnishings and fittings should be kept clean and it should be possible to keep the surfaces of floors, walls and ceilings clean.

Cleaning and the removal of waste should be carried out as necessary by an effective method. Waste should be stored in suitable receptacles.

2.5 Room dimensions and space:
Workrooms should have enough free space to allow people to move about with ease.

The volume of the room when empty, divided by the number of people normally working in it, should be at least 11 cubic metres. All or part of a room over 3.0 m high should be counted as 3.0 m high.

11 cubic metres per person is a minimum and may be insufficient depending on the layout, contents and the nature of the work.
