Night Work and Low-Light Safety
Construction and general industry · Ver en español
Talking points
- OSHA requires minimum illumination levels for construction areas: 5 foot-candles for general construction, 3 foot-candles for walkways and stairs, and 10 foot-candles for indoor shops.
- Portable task lighting — LED towers, string lights, headlamps — supplements area lighting. Position task lights to illuminate the work without creating blinding glare or deep shadows.
- Trip and fall hazards that are visible in daylight become invisible at night. Walk paths must be well-lit and clear of debris, cords, and stored materials.
- High-visibility clothing with retroreflective strips is essential for night work. Class 3 garments with reflective bands on the torso, arms, and legs provide the best nighttime visibility.
- Fatigue compounds the risks of night work. Circadian rhythm disruption reduces alertness and reaction time. Schedule the most hazardous tasks for the early hours of the shift when workers are most alert.
Ask the crew
Is our work area adequately lit for tonight's tasks — or do we need additional lighting before we start?

A toolbox talk is a short safety briefing. It supports the training a standard requires; it does not replace it.
