The law requires that a workplace must have enough and suitable lighting.
For transport safety, all roads, manoeuvring areas and yards should be sufficiently lit.
Areas around junctions, buildings, plant, pedestrian areas, and places where there is regular movement of vehicles will require special attention.
Glare from the sun can sometimes be a problem for drivers. Measures may be needed to avoid this (for example sun visors).
Measures may also be needed to avoid a strong change in the amount of light between the inside and outside of buildings.
A farmer died after falling 4 m through a roof light while carrying out repairs to a barn roof. To reach the area of the in-sheet roof which needed repairing he had to pass a number of roof lights which had not been covered or fenced off. A colleague had been passing up materials but had gone to make a drink at the time of the accident.
The farmer doing the repairs was found semi-conscious beneath a broken roof light and was taken to hospital. He died nine days later as a result of head injuries.
A warehouse operative suffered severe head injuries and died after falling 11 m through a roof light while inspecting the roof for sections which needed repairing. He was examining roof lights installed on the warehouse roof when he tripped and fell onto the roof light. The roof light broke under his weight and he fell to the concrete floor below. The employers were fined £35 000.
A cleaning company was fined £15 000 after one of its employees fell just under 7 m and suffered a fractured skull, bruising and a dislocated finger. He was cleaning gutters on a fragile roof when he tried to cross from one side of the roof to the other. His foot slipped and he fell through a plastic roof light.
