When men are working after dark, what must be provided?

• A. Illumination
• B. Personal protective equipment
• C. Ventilation
• D. Emergency communications

Answer: (A)

Adequate illumination is essential when work continues after dark. Low visibility increases the risk of trips, falls, misreading gauges or controls, and missing hazards, so providing sufficient lighting helps workers see clearly, move safely, and perform tasks accurately. While personal protective equipment, ventilation, and emergency communications are important for overall safety, they do not specifically address the visibility challenge posed by darkness in the same direct way. In nighttime operations, reliable lighting—area lights, task lights, and backup illumination—must be provided and maintained to keep the work environment safe.
