What is the first step in the Hierarchy of Controls?

The first step in the Hierarchy of Controls is elimination. This approach is fundamentally about removing hazards entirely from the workplace or environment. By eliminating the source of the hazard, the risk of injury or illness associated with it is completely eradicated, which represents the most effective means of control.

Elimination focuses on a proactive strategy that not only prevents accidents but also can significantly reduce reliance on other control methods that may be less effective on their own. For example, if a toxic chemical used in a process can be replaced with a non-hazardous substance, the danger posed by the chemical is completely negated.

In contrast, the other options, such as substitution, engineering controls, and warnings, are essential components of the control hierarchy; however, they do not offer the same level of risk reduction as elimination. These methods might manage hazards but still leave some level of risk in place. Therefore, elimination being prioritized as the first step reflects its status as the most comprehensive and effective measure in achieving a safer workplace.
