Which approach best represents the preferred strategy for managing occupational health hazards according to the hierarchy of controls?

Accepted Answer

Eliminate or substitute the hazard before relying on engineering, administrative, or PPE controls

Answer

The hierarchy of controls prioritizes elimination and substitution above all other control methods because they address hazards at the source.

Accepted Answer

Time-Weighted Average

Answer

TWA stands for Time-Weighted Average, representing the average exposure concentration over a specified time period, typically an 8-hour workday.

Question 5

Which type of hearing loss results from prolonged exposure to high noise levels and is permanent and irreversible?
