Which of the following is NOT part of the hierarchy of risk control?

In risk management, particularly in the context of workplace safety, the hierarchy of risk control is a structured approach that prioritizes strategies to manage and mitigate risks. The first and most effective step is elimination, which involves completely removing the hazard. If elimination is not feasible, substitution follows, where a less hazardous option is used instead.

Awareness plays an essential role in maintaining safety but is not a formal step within the hierarchy of risk control itself. Awareness is crucial for recognizing hazards and understanding safety procedures, but it does not directly implement risk control measures.

Personal accountability is also critical in safety management, as it emphasizes the responsibility of individuals to adhere to safety practices. However, like awareness, it does not constitute a direct risk control strategy within the hierarchy. The focus is on proactive measures to eliminate or reduce risks, rather than on the personal responsibilities of workers. Therefore, personal accountability does not fit into the defined framework of the hierarchy of risk control, making it the correct answer to this question.
