What one of the following is NOT a "engineering control"?

Correct! Wrong!

Explanation:
Engineering controls are more successful in eliminating or reducing hazards than administrative controls or personal protective equipment (PPE). HEPA filters that collect dangerous pollutants, dampers that can physically isolate a ventilation system, and fire suppression systems that activate automatically when a fire begins are a few examples of engineering controls. Because they aim to change behavior and are only effective if employees see them and heed them, warning signs are an administrative control because they do not deal with the hazard directly.

Which of the following lessens the likelihood that a circuit may serve as an ignition source?

Correct! Wrong!
