Hierarchy of Hazard control is a system used in industry to minimize or eliminate exposure to hazards. It is a widely accepted system promoted by numerous safety organizations. This concept is taught to managers in industry, to be promoted as standard practice in the workplace. The hierarchy of hazard controls are in order of decreasing effectiveness.
5 Levels of the Hierarchy
- Removing the hazard from the work place.
- Most effective way to control a risk.
- Should be used whenever possible.
- Substituting one chemical for another less harmful chemical.
- E.G, Instead of using benzene (causes cancer) consider ketones, toluene.
3. Engineering –
- Engineering controls are methods that are built into the design of a plant, equipment or process to minimize the hazard.
- Types of engineering controls are: Process control; Enclosure and/or isolation of emission source; and Ventilation.
4. Administrative Controls –
- Adopting standard operating procedures or safe work practices.
- Providing appropriate training.
- Information to reduce the potential for harm and/or adverse health effects to person.
- Isolation and permit to work procedures are examples of administrative controls.
5. Personal Protective Equipment –
- Includes: Gloves; glasses; earmuffs; aprons; safety footwear; masks.
- Usually used in conjunction with one or more of the other control measures
