Which type of control method is described as using physical controls implemented at the engineering stages?

The answer identifies engineering controls as the appropriate type of control method that utilizes physical controls implemented during the engineering stages. Engineering controls focus on designing or modifying equipment and processes to reduce hazards at the source. This approach aims to minimize the risks involved by altering the physical environment or the way tasks are performed, thus improving safety and efficiency.

For example, in a workplace setting, engineering controls might involve installing safety barriers, ventilation systems, or automatic shut-off devices. By addressing potential hazards directly within the design phase, engineering controls are often considered the most effective way to mitigate risks because they change the environment or equipment rather than relying solely on employee behavior or administrative practices.

Training controls, administrative controls, and behavior controls focus more on human factors, training personnel, and implementing policies to manage risks rather than physically modifying the environment or engineering processes.
