Question

If a hazard cannot be eliminated or replaced, it can sometimes be isolated, contained or otherwise kept away from workers. What is this type of engineering control called?

1) Elimination control
2) Substitution control
3) Isolation control
4) Containment control

Answer 1

The correct type of engineering control for keeping a hazard away from workers when it cannot be eliminated or replaced is (3) Isolation control.

Step-by-step explanation:

When a hazard cannot be completely removed or replaced at a workplace, it can sometimes be managed by keeping it away from workers using a method of engineering control. This comes in the form of isolation control or containment control. Isolation controls include the physical separation of the hazard from the worker, such as barriers or remote handling equipment. Containment controls involve enclosing the hazard or using equipment to restrict the hazard's influence on the workplace environment. In light of the provided options and the context of the question, the correct answer is (3) Isolation control, as it refers to engineering practices that physically separate a hazard from workers.
