Q

How do you test and correct for insufficient light problems?

A

Measure the average of illumination throughout the workplace. Compare this to the recommended levels

Look for shadows, especially over work areas and on stairways

Ask workers if they suffer from eye strain or squint to see

Q

To correct insufficient light:

A

Replace bulbs on a regular schedule.

Q

How do you correct glare problems?

A

Using several small low-intensity light fixtures rather than one large high-intensity

Using light fixtures that diffuse or concentrate light well.

Covering bare bulbs with louvers, lenses or other devices to control light

Increasing the brightness of the area around the glare source

Using adjustable local lighting with brightness controls

Positioning light fixtures to reduce reflected light that is directed towards the eyes
