Introduction:

Hazard identification and risk assessment (HI & RA) form the foundation of any effective health and safety management system. Over my 20 years of experience, I have witnessed the critical role of proper risk assessment in successful HSE management system and support positive safety culture. However, I have also come across numerous safety systems marred by flawed or inadequate risk assessments. These shortcomings not only compromise incident control and prevention efforts but also disrupt the overall health and safety management system. This article delves into the basic flaws that plague hazard identification and risk assessment processes, shedding light on their consequences and the need for improvement.

1. Poor Hazard Identification Techniques:

Effective hazard identification relies on robust techniques, yet many systems fall short in this area. Some common flaws include limited scope, overlooking key hazard sources such as weather conditions or duty timings, inadequate observation of actual work, lack of consultation with concerned workers, failure to identify routine or non-routine activities, and ignoring health and environmental hazards.

2. Neglecting Potential Harm to All Parties:

Failure to consider all potentially affected parties is a significant flaw. Untrained workers, visitors, or guests may be exposed to hazards, and their safety should not be overlooked in the risk assessment process.

3. Inadequate Assessment of Consequences:

Flawed risk assessments often fail to establish a clear link between hazards and their true consequences. They may overlook routine or non-routine jobs, rely on general terms such as "injury" or "fatality" without specifying body parts or types of injuries, and neglect the need to evaluate each hazard individually.

4. Weak Risk Evaluation:

Risk evaluation requires a sound understanding of probability and severity, but many assessments fall short in this aspect. Issues include a poor understanding of risk rating, inappropriate selection of risk matrices, confusion between qualitative and quantitative risk evaluation, and evaluating overall activities instead of isolating individual hazards and their impacts.

5. Inadequate Control Measures:

Failure to adhere to the hierarchy of control measures is a major issue in risk assessments. Overreliance on personal protective equipment (PPE) at the expense of other controls, neglecting administrative controls such as standard operating procedures and trainings, and lack of consideration for engineering controls, isolation, elimination, and substitution contribute to weak risk management.

6. Misguided Residual Risk Assessment:

Inadequate control measures lead to misleading residual risk assessments. Proper quantification of control measures, multiplying them with actual risk evaluations (e.g., assigning a weightage of 1 to no control, 0.8 to PPE, 0.6 to administrative controls, 0.4 to engineering controls, 0.2 to substitution and 0 to eliminate), is crucial to obtaining accurate residual risk values.

7. Ineffective Communication:

Even excellent risk assessments yield zero benefits if the detailed information is not effectively communicated to all relevant workers. Platforms such as toolbox talks provide ideal opportunities to disseminate risk assessment details and ensure understanding among employees.

8. Incompetent or Non-Concerning Risk Assessors:

One additional flaw in hazard identification and risk assessment is the involvement of incompetent or non-concerned risk assessors. When untrained or disinterested risk engineers conduct risk assessments, it undermines the accuracy and reliability of the process. Lack of knowledge, skills, and commitment can lead to overlooking critical hazards, underestimating risks, and inadequately implementing control measures. Competent and engaged risk assessors are essential for conducting thorough and effective assessments that truly address the safety needs of the organization.

9. Lack of Management Support and Approval:

Risk assessments often lack management consent. While line managers ideally play an active role in HI & RA, at the very least, they should be fully aware of the final reports and well-versed in the process.

10. Neglecting Periodic Review:

Flawed risk assessments overlook the importance of regular review. Reviews should be done after any incidents or near miss (either due to failure of any control or ignored hazard), installation of new equipment, introduction of new processes (in both cases new type of hazards may be involved), and periodically to ensure ongoing effectiveness.

Conclusion:

Effective hazard identification and risk assessment are vital to robust safety management systems. However, the flaws discussed above can undermine the integrity of risk assessments, leading to compromised safety efforts, increased incident rates, and a disturbed safety management system. By addressing these flaws and striving for continuous improvement, organizations can enhance their risk.
