What is the first step in the Hierarchy of Controls?

The first step in the Hierarchy of Controls is elimination. This approach prioritizes the complete removal of a hazard from the workplace or environment, which inherently reduces or eliminates the risk of harm or exposure. By eliminating hazards at the source, it creates a safer environment without relying on personal protection measures or additional controls.

This method is the most effective because if a hazard does not exist, there is no risk associated with it. In the context of trauma and crime scene management, this could involve removing items or substances that pose a biological or chemical risk before any cleanup or restoration activities begin. The focus on elimination underscores a proactive approach to safety and health, ensuring that risks are handled in the most effective way possible before considering other control measures.

Other options like substitution, engineering controls, and administrative controls represent subsequent tiers in the hierarchy and are employed when elimination is not feasible. These strategies involve modifying the environment, processes, or behaviors to mitigate risks but are not as effective as removing the hazard outright.
