Lighting Safety Issues

At one time, good lighting simply meant enough lighting. However, ergonomic studies in business offices attest to the importance of lighting. Improper lighting can cause rapid fatigue, headaches, eyestrain, blurred vision, dry and irritated eyes, slowed refocusing, neck ache, backache, sensitivity to light, double vision, and more.

Aside from the health issues, workers are also less productive. Computer monitors complicate matters. With an increased number of people using home offices with computers, we need to apply what we have learned in commercial lighting and adapt it to suit home office needs and décor.

In general, the light should be brightest on your immediate work area, but do not over-illuminate or you will create too much contrast. Lighting levels should decrease as you move into the general environment of the room. Aim for a 5:3:1 ratio for work, peripheral work area, and immediate surroundings, respectively. The best way to achieve a proper balance is with a combination of general lighting (including controlled daylighting) and task lighting.

Safety is of utmost importance when working with electricity. Develop safe work habits and stick to them. Be very careful with electricity. It may be invisible, but it can be dangerous if not understood and respected.
