Introduction
In today’s dynamic work environments, effectively managing workplace hazards is crucial. The hierarchy of risk controls offers a proven framework that guides organizations through selecting the most efficient safety measures—from complete elimination of risks to the use of personal protective equipment (PPE). By following these steps, you can significantly reduce the chances of injuries and illnesses on the job.

What Is the Hierarchy of Risk Controls?
The hierarchy of risk controls is a structured method used to mitigate workplace hazards. It prioritizes interventions based on their effectiveness. Starting with elimination, the most desirable option, each subsequent level represents a reduced ability to fully control risks. Understanding this hierarchy is key to making informed decisions about safety in any work environment.

The 5 Levels of Risk Control Measures
1. Elimination – The Most Effective Approach
- Definition: Elimination removes the hazard entirely from the workplace.
- Why It Works: By completely eliminating a risk, you ensure there is no possibility of injury or harm.
- Example: Replace a noisy machine with a quieter model to eradicate the risk of noise-induced hearing loss.
2. Substitution – A Safer Alternative
- Definition: Substitution involves replacing a hazardous material, ingredient, or piece of equipment with a less dangerous one.
- Benefits: This method minimizes risk by swapping out hazardous elements for safer alternatives.
- Example: Replace a chemical that causes skin irritation with one that is less harmful.
3. Engineering Controls – Designing Out the Danger
- Definition: Engineering controls work by isolating the hazard or modifying the process to reduce exposure.
- Implementation: Common methods include installing machine guards or ventilation systems.
- Example: Installing ventilation to remove toxic fumes from the workplace environment.
4. Administrative Controls – Changing Work Practices
- Definition: Administrative controls modify how work is performed, reducing exposure through process changes.
- Strategies: These can include revised work schedules, improved signage, or new operational procedures.
- Example: Implementing mandatory breaks for employees operating loud machinery to reduce prolonged exposure.
5. Personal Protective Equipment (PPE) – The Last Line of Defense
- Definition: PPE involves the use of gear such as gloves, goggles, or helmets to protect workers from hazards.
- Limitations: PPE is considered the least effective control because it depends on proper use and does not eliminate the hazard.
- Example: Using safety glasses and gloves when handling chemicals.
Why the Hierarchy of Risk Controls Matters
- Effectiveness Varies: Not all safety measures provide the same level of protection. The hierarchy helps prioritize the most effective controls.
- Preventive Impact: Implementing the right control measures can prevent incidents, injuries, and occupational illnesses.
- Continuous Improvement: Regularly reviewing and updating safety measures leads to a safer workplace over time.

Real-Life Success Stories
- Manufacturing: A plant eliminated a hazardous chemical, reducing worker exposure to zero.
(Read our detailed Manufacturing Safety Case Study for more information.) - Construction: A company replaced traditional ladders with scaffold systems, significantly lowering the risk of falls.
(Learn more about scaffold safety standards on OSHA’s website.) - Healthcare: A hospital installed sharps disposal containers as an engineering control to prevent needle-stick injuries.
These examples illustrate how applying the hierarchy of risk controls can result in measurable improvements in safety.
Best Practices for Implementing Risk Controls
- Identify and Assess Hazards: Begin by thoroughly identifying workplace hazards and assessing associated risks.
- Follow the Hierarchy: Start with the most effective measure (elimination) and work down the list.
- Engage Employees: Involve your team in the decision-making process to ensure practical and effective solutions.
- Monitor and Adjust: Regularly review the effectiveness of your controls and adjust them as needed.
- Pro Tip: Aim for the highest level of control possible to maximize safety.

Takeaways & Call to Action
- Key Takeaways:
- The hierarchy of controls is an essential framework for workplace safety.
- Prioritize eliminating and substituting hazards over relying solely on PPE.
- Safety is an ongoing process—continuous improvement is key.
- Call to Action:
- Evaluate Your Workplace: Conduct a thorough hazard assessment in your work area.
- Collaborate: Share your findings and ideas with your team.
- Act: Report concerns to management and commit to implementing the most effective safety measures.
