Quizplus · Accepted Answer

Ventilation systems are an example of the first line of defence as they can help to control exposure to environmental hazards by removing or diluting harmful substances in the air. Changing jobs, respirators, and limiting repetitive motion may also be methods of controlling exposure, but they are typically considered second or third lines of defence.
