Question

What is Hierarchy of Controls (From most effective to least effective) ?

Answer 1

The hierarchy of controls from most effective to least effective includes elimination, substitution, engineering controls, administrative controls, and personal protective equipment (PPE).

Step-by-step explanation:

Hierarchy of Controls from Most Effective to Least Effective:

1. Elimination: Involves removing the hazard from the workplace. For example, replacing a hazardous chemical with a non-hazardous alternative.
2. Substitution: The hazard is replaced with something less hazardous. For instance, using a safer chemical in place of a toxic one.
3. Engineering Controls: Physical modifications are made to the workplace to prevent exposure to the hazard. For instance, installing ventilation systems to remove harmful fumes.
4. Administrative Controls: These involve changing work practices and policies to minimize exposure. For example, implementing regular breaks and job rotation to reduce prolonged exposure.
5. Personal Protective Equipment (PPE): PPE is the last line of defense and includes items such as masks and goggles. It should only be relied on when other controls are not feasible or effective.
