Which type of hazard control changes processes to minimize employee exposure to risks?

The correct choice is engineering controls, which focus on modifying processes, equipment, or the work environment to reduce hazards and limit employee exposure to risks. This type of control involves implementing changes that target the source of the hazard itself, effectively altering the way tasks are performed to create a safer workplace.

For instance, an engineering control could involve redesigning a piece of machinery to include safety guards that prevent employees from coming into contact with dangerous moving parts. Additionally, the implementation of ventilation systems to remove harmful fumes is another example of an engineering control that addresses potential hazards at the source.

In contrast, administrative controls involve policies or procedures that change how work is done, such as rotating employees to minimize exposure time but do not alter the hazard itself. Behavioral controls require altering workers’ actions rather than modifying the environment or processes. Training focuses on educating employees about hazards and safe practices, which is critical but does not change the processes or equipment involved in their work. Engineering controls are unique in their direct approach to eliminating or minimizing risks through design and structural changes.
