Which lighting level is recommended for handwashing areas?

Explanation:
Good lighting is essential for handwashing to ensure you can see surfaces clearly as you scrub. Illuminance is measured in foot-candles, and around 20 foot-candles (about 215 lux) provides enough visibility to see soap, detect grime, and verify that hands and under nails are properly cleaned. Lighting at this level supports an effective handwashing technique without being unnecessarily bright. If the level were much lower, it would be hard to spot remaining dirt; much higher levels isn’t typically needed for routine handwashing and can be tiring. So the recommended level is 20 foot-candles.
