Which of the following are methods of controlling risks?

The correct answer focuses on two key methods of controlling risks: the elimination of hazards and the implementation of engineering controls.

Eliminating a hazard is the most effective way to manage risk because it removes the source of potential harm altogether. For example, if a hazardous chemical is present in a workplace, replacing it with a non-hazardous alternative would completely eliminate the risks associated with that chemical.

On the other hand, engineering controls involve modifying equipment, facilities, or processes to reduce the risk of exposure to hazards. This could include installing ventilation systems, using machine guards, or implementing safety interlocks. These controls do not completely eliminate the hazard but significantly mitigate the risk of injury or illness.

Methods that involve improvements in communication, refreshments, increased break times, or checklists may support overall health and safety in a workplace, but they do not directly address or control inherent risks in the same effective manner as the elimination of hazards and engineering controls. Thus, the chosen response encompasses essential and proactive strategies for risk management.
