What is the “Hierarchy of Controls” in workplace safety?

The "Hierarchy of Controls" is a key framework used in workplace safety that prioritizes methods for managing and reducing hazards. The primary focus of this hierarchy is to emphasize the most effective approaches to eliminate or mitigate risks associated with workplace hazards. It is structured to help safety professionals and workers identify the best possible solutions, beginning with the most effective control measures and moving down to less effective ones.

At the top of the hierarchy are strategies that aim to eliminate the hazard entirely, such as redesigning equipment or processes. If elimination is not possible, the next levels include substitution (replacing a hazardous substance or process with a less dangerous one), engineering controls (physical modifications to the workspace to minimize exposure), administrative controls (changes to workplace policies or procedures), and finally, personal protective equipment (PPE), which is the last line of defense.

This structured approach provides a clear method for addressing hazards systematically, ensuring that teams prioritize more effective controls that can lead to safer work environments. It contrasts with the mentioned alternatives, which do not convey systematic risk management strategies.
