Lighting for Employees

Employees must have enough light to do their work safely. The link below shows a table giving the minimum illumination intensities in foot-candles* for typical areas at hazardous waste operations.

Foot-Candles Work Area
5 General work areas
3 Excavation and waste areas, access ways, active storage areas, loading platforms, refueling, and field maintenance areas
5 Indoors
5 Tunnels, shafts, and general underground work areas
10 Shop areas
30 First-aid stations, infirmaries, and offices

* Illumination is commonly measured in foot-candles. One foot-candle is the illumination produced by one candle at a distance of one foot. The most practical way to measure illumination is with a light meter.
