The hierarchy of controls
The hierarchy of controls is a system used in occupational safety and health to minimize or eliminate exposure to hazards. It is arranged in a specific order to prioritize the most effective methods of control. The hierarchy is typically represented as a pyramid with five levels, from the most effective to the least effective. Here’s a breakdown of each level: 1. Elimination Definition: Completely remove the hazard from the workplace. Examples: Redesigning a process to eliminate the use of a hazardous chemical. Automating a manual handling process to remove the need for lifting heavy objects. Effectiveness: This is the most effective method because it completely removes the hazard, eliminating any risk of exposure. 2.

Effectiveness: This is the second most effective...
