What type of controls take the form of barriers and guards that a hazard exists?

The type of controls that take the form of barriers and guards to mitigate hazards are known as physical or engineering controls. These controls are designed to prevent exposure to hazards by creating a physical separation between the hazard and individuals, such as safety guards on machinery, handrails, or safety nets. By implementing these barriers, the risk of accidents and injuries can be significantly reduced in various environments.
