What is the primary purpose of the hierarchy of controls?

The primary purpose of the hierarchy of controls is to rank methods for controlling hazards effectively. This structured approach provides a systematic framework to evaluate and implement various hazard control strategies, ranging from the most effective (elimination of the hazard) to the least effective (personal protective equipment). By prioritizing control measures, it helps organizations focus on solutions that will provide the greatest risk reduction, ensuring a safer working environment.

Other options, while related to safety and hazard management, do not capture the essence of the hierarchy of controls. For instance, identifying chemical hazards is more about recognizing potential dangers rather than controlling them, assessment of workplace safety might involve multiple factors beyond just controlling hazards, and standardizing risk assessments refers to a consistent approach to evaluating risks rather than specifically ranking control methods.
