The minimum illumination intensity required for general construction worksite areas is set at 10 foot-candles. This requirement is critical for ensuring the safety of workers in construction environments, where visibility can directly impact accident rates and overall safety. Adequate lighting is essential for workers to perform their tasks effectively while minimizing the risk of trips, falls, or other accidents that can occur in low-light conditions.

The 10 foot-candle standard helps ensure that work surfaces are visible enough for employees to see potential hazards, read instructions, and safely operate machinery. It also aids in maintaining an overall awareness of the work environment, allowing workers to navigate spaces safely and efficiently.

Understanding this standard is essential for safety technicians, as it underscores the importance of proper lighting in maintaining a safe and compliant construction site. Other illumination standards may apply to specific tasks or conditions, but for general construction work areas, 10 foot-candles is the recognized minimum.
