Which type of hazard control involves barriers, guards, or signs to protect individuals?

The concept of hazard control through the implementation of barriers, guards, or signs is primarily classified under physical controls. This approach focuses on using tangible, physical means to reduce or eliminate exposure to hazards in the workplace or other environments.

Physical controls act as a first line of defense by providing direct protection from hazards. For example, physical barriers can separate hazardous areas from safe zones, while guards can prevent workers from coming into contact with dangerous machinery. Signs serve as visual warnings that reinforce safe practices and indicate hazardous zones, helping to inform individuals of potential risks.

In contrast, other types of controls, such as engineering controls, are focused on modifying equipment or processes to mitigate risks. Administrative controls deal with policies and procedures that govern how tasks are performed, and behavioral controls focus on modifying individuals' actions or behaviors through training and awareness. While these controls are important, they operate differently than the straightforward protective measures provided by physical controls.
