Risks and prevention — Night work
Night work on construction sites increases accident risk due to fatigue, reduced visibility, and decreased alertness. The CSTC requires adequate lighting of work areas (minimum 50 lux for traffic areas, 100 lux for active work zones).
Class 3 high-visibility garments (with retro-reflective bands) are required for night work. Fatigue management includes more frequent breaks, rotation of high-risk tasks, and enhanced supervision. Communications must account for reduced ambient noise (machinery near residential areas).
