Which of the following is an example of a physical control?

A physical control is a tangible measure implemented to reduce or eliminate hazards, typically through mechanical or structural means. Barriers such as fences fall into this category as they are physically constructed to prevent access to hazardous areas, thereby providing a clear and effective means of protection. These structural elements serve to mitigate risk by creating a physical separation between individuals and potential dangers.

On the other hand, safety training sessions, regular safety reports, and emergency drills are essential components of a comprehensive safety program, but they do not qualify as physical controls. Safety training and drills focus on educating personnel and preparing them for emergencies, while safety reports analyze data and assess risks. While all are vital for enhancing safety awareness and operational readiness, they do not involve the creation of physical barriers or changes to the environment itself, which is key to defining physical controls.
