Which hazard control strategy is used to remove a or place barrier between the worker and hazard?

The correct answer is Engineering controls.

Engineering controls are designed to eliminate hazards or reduce them to acceptable levels by modifying the physical work environment. This can be done through a variety of measures, such as:

* Using machines and processes that are designed to minimize the risk of exposure to hazards.

* Installing physical barriers, such as guards or shields, to prevent workers from coming into contact with hazards.

* Using ventilation systems to remove hazardous fumes, dust, or gases from the workplace.

* Implementing administrative controls, such as work schedules or training programs, to minimize the risk of exposure to hazards.
