Which of the following is the correct lighting level for other surfaces and equipment in the same areas and in toilet rooms?

• A. 125
• B. 50
• C. 100
• D. 75

Answer: (B)

Lighting levels are chosen to ensure you can safely see surfaces and equipment without wasting energy. For general surfaces and equipment in the same areas, including toilet rooms, the standard illumination level is 50 foot-candles. This provides enough brightness to notice spills, read gauges, and identify potential hazards without the glare or excessive power use that comes with higher levels.

Higher values, like 100 or 125 foot-candles, are used for tasks that require very precise viewing or inspection. Lower values would make it harder to detect issues. So 50 foot-candles is the appropriate level for these general areas and restrooms.
