Used this in everything you do in risk assessment
The image you've shared shows the "Hierarchy of Control", a key concept in occupational health and safety used to minimize or eliminate exposure to hazards. It is arranged from most effective to least effective measures.
Hierarchy of Control – Information and Use
1. Elimination (Most Effective)
-
Definition: Physically remove the hazard.
-
Example: Removing a dangerous machine from the workplace.
-
Use: First choice whenever possible. Completely eliminates risk.
2. Substitution
-
Definition: Replace the hazard with a safer alternative.
-
Example: Using non-toxic chemicals instead of toxic ones.
-
Use: When elimination is not practical, use less hazardous options.
3. Engineering Controls
-
Definition: Isolate people from the hazard.
-
Example: Using guards on machines, installing ventilation systems.
-
Use: Reduces exposure without relying on worker behavior.
4. Administrative Controls
-
Definition: Change the way people work.
-
Example: Training, safety procedures, job rotation, signage.
-
Use: Enhances safety awareness and limits time of exposure.
5. Personal Protective Equipment (PPE) (Least Effective)
-
Definition: Protect the worker using gear.
-
Example: Helmets, gloves, safety goggles, high-visibility clothing.
-
Use: Used as a last line of defense when other methods aren’t sufficient.
Application:
This hierarchy guides safety professionals and workers in designing safe work environments. The aim is always to control hazards as high up the pyramid as possible to maximize safety and reduce reliance on personal behavior or gear.
