T here are a variety of methods for controlling or reducing noise levels in indoor environments. The most obvious choice is to eliminate the source of the noise. If this is not feasible, it might be possible to move the source of noise to an area where it will not cause a problem. If it is impossible to separate people from the noise source, it may be possible to isolate the noise source or dampen the sound, or as a last resort provide personal protective equipment. 7.3 Lighting T he quantity, quality and distribution of illumination plays an important role in the overall indoor environment.
Deficient lighting can cause headaches and eye fatigue.
In these cases, it may not be the quantity, but the quality of both environmental and VDT screen illumination which is the source of the problem. L ighting should be diffused and directed so as to avoid high contrast in a given work area and to avoid annoying glare. 7.4 Temperature Extremes W hen evaluating problems concerning exposure to temperature extremes, one must consider if people are merely uncomfortable or are the conditions such that continued exposure will cause the body temperature to fall below or rise above safe limits. For comfort concerns, you should contact your department head or building proctor, who may in turn contact Facilities Management or your designated maintenance department. Exposure to severe cold can result in hypothermia and frostbite which may also be life threatening.
