Why should workers be equipped with appropriate personal protective equipment?

Equipping workers with appropriate personal protective equipment (PPE) primarily serves to enhance their visibility to passing trains. This is crucial in ensuring safety in environments where heavy machinery or trains operate, as being visible significantly reduces the risk of accidents. The bright colors and reflective materials commonly used in PPE help workers stand out against their surroundings, making it easier for operators to see them from a distance.

Furthermore, while company policy, compliance with regulations, and maintaining a professional appearance are important considerations, the primary goal of implementing PPE is to protect workers from potential hazards in their work environment. These protective measures directly contribute to reducing the likelihood of injuries and fatalities, especially in high-risk areas. Thus, choice A best answers the question regarding the importance of appropriately equipping workers for their safety.
