Why are physical controls important in risk management?

Physical controls are crucial in risk management because they provide direct mitigation of hazards. These controls are tangible measures designed to eliminate or reduce exposure to certain risks, ensuring a safer environment. For instance, installing safety barriers, ventilation systems, or automatic shut-off valves can prevent accidents or minimize the impact of a hazardous situation. By directly addressing the source of potential hazards, physical controls play a key role in protecting lives, property, and the environment from risks.

In contrast, while the other options may touch upon aspects of efficiency or cost, they do not encapsulate the fundamental purpose of physical controls in risk management. The essence of risk management is about addressing risks directly and effectively, which is exactly what physical controls accomplish.
