The first step in the hierarchy of controls for managing workplace hazards is elimination. This approach focuses on completely removing the hazard from the workplace, thereby preventing any risk of exposure to it. By eliminating a hazard, you effectively protect employees without relying on other methods that might only reduce risk rather than eliminate it entirely.

This strategy is the most effective because it addresses the root of the problem, ensuring that incidents cannot occur. If an hazard can be removed, there is no need for additional controls, such as substituting with a less hazardous material or implementing administrative and engineering controls to mitigate the remaining risk.

In the hierarchy of controls, elimination is prioritized because it fundamentally changes the environment in which workers operate, creating a safer workplace without imposing behavioral changes or reliance on safety equipment. Once elimination is deemed impossible, other methods can be considered, but they are inherently less effective than removing the hazard altogether.
