What does the hierarchy of controls prioritize in mitigating workplace hazards?

The hierarchy of controls is a systematic approach used to mitigate workplace hazards, and it prioritizes methods based on their effectiveness in protecting workers. The correct focus is on elimination of hazards, which represents the most effective strategy in this hierarchy. When a hazard can be completely removed from the work environment, it reduces the potential risk to workers entirely.

Following elimination, the hierarchy recommends other control measures such as substitution (replacing hazardous materials with safer alternatives), engineering controls (modifying equipment or processes to reduce risk), administrative controls (implementing policies or procedures to reduce exposure), and lastly personal protective equipment (PPE). By placing elimination at the top of the hierarchy, it underscores the principle that it is always preferable to remove the hazard altogether rather than relying on lesser measures that still leave some level of risk.

Selecting the most cost-effective measures or using PPE above all else misrepresents the primary goal of the hierarchy, which is to protect employees by prioritizing methods that offer the highest level of control over hazards. While cost considerations and the use of PPE are important, they do not take precedence over the elimination of hazards, which is the most effective way to ensure safety in the workplace.
