Challenges in Applying the Hierarchy of Control in NEBOSH

When managing risks and hazards in the workplace, the hierarchy of controls is a fundamental framework for occupational safety and health. Professionals working in health and safety must be familiar with the concepts of the hierarchy of controls, whether seeking certification or professional development through NEBOSH Training. Despite its significance, the Hierarchy of Control in NEBOSH can be difficult to apply in real-world situations. This blog will discuss the most typical challenges and methods to fix the issues when applying NEBOSH’s hierarchy of controls.  

Understanding the Hierarchy of Control in NEBOSH  

From complete elimination to using PPE, the five levels that comprise the “hierarchy of control” provide a systematic framework for risk management in the workplace. The following are the levels, ordered by decreasing efficacy:  

  • Elimination: Hazard elimination aims to make a work environment accessible to potential risks.  
  • Substitution: Substitution entails exchanging the risky item for one that is safer.  
  • Engineering Controls: Make structural adjustments to the work environment to reduce the risk of injury.  
  • Administrative Controls: To lessen the risk, administrative controls should be put in place through rules, procedures, and work practices.  
  • Personal Protective Equipment (PPE): Workers should be provided with personal protective equipment (PPE) as an additional layer of protection against the hazard.

Complexity of Workplace Hazards  

The intricacy of potential risks in the workplace is a significant challenge to using the NEBOSH hierarchy of controls in risk assessments. Identifying and prioritising control measures in workplaces with multiple hazards across different dimensions can be difficult. Students might need help figuring out how various risks interact with one another, and which controls are best for different situations.  

Balancing Effectiveness and Feasibility  

Another challenge is balancing the practicality and efficiency of control measures and their effectiveness. The most effective control measures are usually elimination and substitution, but these options are only sometimes practical due to cost, technology, or operational constraints. It can be a complicated and nuanced decision-making process, but learners must consider the costs and benefits of each control measure.  

Limited Awareness of Control Options  

Some students may need help understanding the hierarchy of controls or the variety of options available at each level. They might need to learn more about the engineering controls, administrative controls, or personal protective equipment (PPE) choices that apply to their job or industry. Inadequate risk management outcomes may result from their inability to recognise and suggest suitable control measures due to a lack of awareness.  

Overcoming Challenges and Enhancing Success  

Despite the difficulties, there are several tactics that students can use to succeed in NEBOSH Training and apply the hierarchy of control:  

Develop a Comprehensive Understanding  

Learn all you can about the six tiers of control, the reasoning behind them, and how to apply them to various risks and industries. Get to know applicable case studies, real-life examples, and best practices to learn about control strategies that work.  

Conduct Thorough Risk Assessments  

Prioritise performing comprehensive risk assessments to identify and evaluate workplace hazards systematically. Be proactive in identifying potential hazards and include those with a stake in the process, such as frontline employees and safety representatives. Consider hazard severity, exposure likelihood, and possible consequences for effective control measure prioritisation.  

Seek Guidance and Collaboration  

When faced with a problem or needing extra support, it is wise to consult with seasoned health and safety experts, colleagues, and others in the field for advice and to work together to find a solution. Join professional groups, participate in online forums, and take advantage of networking events to meet other people going through the same things you are and to swap tips, tricks, and resources.  


Some challenges must be overcome to implement the hierarchy of controls in NEBOSH Training. These include a lack of knowledge about control options, resistance to change, and the complexity of workplace hazards. Learners can manage workplace risks more effectively if they fully grasp the principles of the hierarchy of control, perform thorough risk assessments, seek guidance and collaboration, take a proactive approach, and advocate for resources and support. Health and safety experts can help make workplaces safer, healthier, and more resilient if they tackle these issues directly.
