What does 'risk hierarchy' refer to?

'Risk hierarchy' refers to a systematic approach to controlling risks in the workplace by ranking risk control measures from most to least effective. This concept emphasizes that the best outcome for managing risks is to first eliminate the hazard completely, followed by implementing engineering controls, administrative controls, and finally, personal protective equipment (PPE).

This hierarchy prioritizes interventions that remove the source of risk over those that simply mitigate exposure or protect the individual. By following this structured approach, organizations can better protect their employees and create a safer working environment.

Other options do not capture the essence of risk hierarchy. A list of employees trained in safety focuses on personnel rather than on strategies for controlling risks. The history of workplace accidents is about past events and does not provide a proactive approach to managing current risks. Employee opinions on safety measures may highlight perceptions but do not establish a formal ranking of risk control methods.
