In the Hierarchy of Hazard Controls, which level provides the HIGHEST level of protection?

The NIOSH Hierarchy of Controls (highest to lowest protection): 1. Elimination → 2. Substitution → 3. Engineering Controls → 4. Administrative Controls → 5. PPE. Elimination (removing the hazard entirely) is the most effective. PPE is the LEAST effective as it relies on proper use every time and provides a barrier but does not eliminate the hazard. This framework is critical for infection control and occupational safety on the INBDE.
