What safety measure should be implemented when working at night or in dark areas?

Implementing sufficient lighting when working at night or in dark areas is crucial for ensuring safety. Proper lighting enhances visibility, allowing workers to see potential hazards and obstacles clearly, which significantly reduces the risk of accidents and injuries. Adequate illumination helps in differentiating between surfaces, recognizing where to walk, and identifying equipment or tools that could pose dangers.

While worker safety training, reflective gear, and backup alarms are all important safety measures in various contexts, they do not specifically address the immediate risk associated with low visibility during nighttime or in darkness. Sufficient lighting directly tackles the challenge posed by reduced visibility, making it the most relevant safety measure in this scenario.
