What is considered the primary level of hazard control effectiveness?

The primary level of hazard control effectiveness is the elimination of the hazard. This approach is most effective because it removes the danger entirely, ensuring that no exposure or risk remains. Eliminating hazards at the source is the best way to protect workers and the environment from potential harm. This method prevents the occurrence of accidents or incidents related to the hazard and is the preferred strategy in any safety management system.

Using other methods like mitigation measures or precautionary steps still allows the hazard to exist, albeit in a modified form or with some level of control. These approaches may reduce risks but do not eliminate the underlying source of the hazard. Corrective actions normally come into play after an incident has occurred, addressing issues rather than preventing their origin. By focusing on elimination as the top priority, organizations can foster a safer workplace more effectively.
