Applying the Hierarchy of Controls in the Workplace

How to Use the Hierarchy of Controls to Manage Workplace Risks

Applying the Hierarchy of Controls in the Workplace is a practical way to protect employees from hazards. This method helps employers and health and safety representatives find the best ways to reduce or stop risks that can cause harm.

The Hierarchy of Controls is a step-by-step system. It ranks control measures from the most effective to the least effective. By following this order, workplaces can manage risks safely and legally.

The Five Levels of the Hierarchy of Controls

1. Elimination: Remove the hazard completely. This is the safest option. For example, if a dangerous machine is not needed, remove it from the workplace.
2. Substitution: Replace the hazard with something safer. For example, use less harmful chemicals instead of toxic ones.
3. Engineering Controls: Change the way work is done or use physical barriers to reduce risk. This includes installing guards on machines or improving ventilation systems.
4. Administrative Controls: Change work rules or procedures to limit exposure to hazards. This includes training workers, rotating job tasks, or setting safe work hours.
5. Personal Protective Equipment (PPE): Use gear like gloves, masks, or helmets to protect workers. PPE is the last option because it depends on worker compliance and does not remove the hazard.

When you are applying these controls, always start from the top. Try to eliminate or substitute hazards before relying on workers to protect themselves. Engineering and administrative controls can reduce risks but may not fully remove them. PPE should only be used when other controls can’t eliminate the hazard.

For example, if your workplace uses loud machinery, eliminating noise might not be possible. Instead, you could replace noisy machines with quieter ones (substitution), install sound barriers (engineering control), limit the time workers spend near noise (administrative control), and provide earplugs (PPE).

It is important to involve workers in choosing the controls. They can give useful feedback about what works best in practice. Regularly review and update controls to make sure they stay effective as work changes.

Applying the Hierarchy of Controls in the Workplace not only reduces accidents and injuries but also helps comply with South African health and safety laws. It makes the workplace safer and healthier for everyone.

Remember, risk control is a continuous process. Always assess hazards, use the hierarchy to select controls, and check that these controls work well. Good risk management creates a positive work environment and protects lives.
