Occupational Health and Safety (OHS) is a critical component of modern workplace management. Employers are legally and ethically responsible for ensuring the safety, health, and well-being of their employees. One of the most effective ways to assess and improve safety performance is through an occupational health and safety internal audit. This internal auditing process plays a vital role in identifying hazards, ensuring compliance with regulations, and promoting continuous improvement in safety culture.
What is an Occupational Health and Safety Internal Audit?

An Occupational Health and Safety Internal Audit is a systematic, independent, and documented process designed to gather objective evidence and evaluate how well an organization’s health and safety management system meets defined criteria. This process helps ensure that workplace practices align with company policies and international standards. By conducting regular audits, businesses can proactively identify gaps in their systems, reduce risks, and improve overall safety performance.
Typically, an OHS Internal Audit is carried out by trained internal auditors who are familiar with both audit methodology and safety protocols. In some cases, especially within larger or more complex organizations, third-party consultants may be brought in to provide an external perspective. Regardless of who conducts it, the audit must remain impartial and thorough to maintain its effectiveness and credibility.
During the course of an Occupational Health and Safety Internal Audit, auditors evaluate a wide range of organizational elements, beginning with the company’s health and safety policies and procedures. This includes reviewing written documentation, analyzing implementation methods, and assessing how well these policies are communicated and followed across the organization.
Another essential aspect of an OHS Internal Audit is the examination of legal and regulatory compliance. Auditors must ensure that all workplace activities meet local, national, and international health and safety laws. Non-compliance can lead to significant legal penalties and reputational damage, making this a critical part of the audit process.
Risk management practices are also reviewed during an Occupational Health and Safety Internal Audit. Auditors assess how effectively the organization identifies, evaluates, and mitigates hazards. This includes reviewing risk assessments, control measures, and monitoring systems to determine if they are adequate and properly maintained.
The OHS Internal Audit further looks into incident investigation processes. It evaluates whether the organization has a structured approach for recording, analyzing, and learning from workplace incidents and near misses. Proper investigation methods not only help prevent future occurrences but also reflect the maturity of a company’s safety culture.
Training and competency are also key focus areas in an Occupational Health and Safety Internal Audit. Auditors examine whether employees receive appropriate safety training, whether certifications are current, and if workers are competent to perform their roles safely. A well-trained workforce is one of the strongest defenses against workplace accidents and injuries.
Lastly, an OHS Internal Audit assesses emergency preparedness and workplace conditions. Auditors review whether the organization has up-to-date emergency plans, conducts regular drills, and provides necessary safety equipment. They also inspect physical conditions—such as lighting, ventilation, and ergonomic arrangements—to ensure the work environment is conducive to health and safety.
Objectives of occupational health and safety internal audit

One of the key objectives of an Occupational Health and Safety Internal Audit is to evaluate compliance with relevant laws and standards. Organizations must adhere to national regulations such as OSHA in the United States, as well as international frameworks like ISO 45001. Auditors examine whether all legal requirements are understood, implemented, and consistently followed across departments. Compliance not only reduces the risk of legal penalties but also reinforces the company’s commitment to employee well-being.
Another important function of an OHS Internal Audit is the identification of risks in the workplace. This involves detecting both current hazards and those that could potentially arise in the future. By identifying these issues early, organizations can implement preventive measures that reduce the likelihood of accidents and injuries, ultimately creating a safer working environment for everyone.
An Occupational Health and Safety Internal Audit also plays a critical role in promoting continuous improvement within the organization. Auditors assess current procedures, identify gaps or inefficiencies, and recommend corrective and preventive actions. This ensures that the health and safety system is not static but evolves over time to address new challenges, incorporate best practices, and align with updated regulations.
Improving organizational culture is another benefit of conducting an OHS Internal Audit. A strong safety culture requires active participation and awareness from all levels of staff. The audit process encourages communication, transparency, and employee engagement by involving workers in discussions about safety practices and improvements, leading to a shared responsibility for workplace safety.
Finally, an Occupational Health and Safety Internal Audit helps organizations prepare for external evaluations. Whether aiming for third-party certification or anticipating government inspections, internal audits serve as a valuable rehearsal. They allow organizations to identify and correct deficiencies in advance, ensuring that they are fully compliant and ready for formal review by external authorities.
Steps Involved in Conducting an occupational health and safety internal audit

The first step in conducting an Occupational Health and Safety Internal Audit is effective planning. This involves defining the audit’s scope, criteria, and objectives to ensure clarity and focus throughout the process. Once these elements are established, the organization must select a qualified audit team that possesses the necessary knowledge of safety standards and audit techniques. A detailed checklist and a realistic schedule are then developed to guide the audit systematically and cover all essential areas of the health and safety management system.
Once planning is complete, the next phase of the OHS Internal Audit is execution. During this phase, auditors review critical documents and records, such as health and safety policies, training logs, and risk assessments, to ensure they are up to date and effectively implemented. They also conduct interviews with employees and management to understand how well safety procedures are understood and followed. In addition, auditors inspect the physical work environment and observe real-time work practices to verify that conditions align with documented procedures and regulatory standards.
After completing the onsite assessment, the Occupational Health and Safety Internal Audit proceeds with reporting findings. All observations, including non-conformities and potential areas of concern, are documented clearly and objectively. Auditors assess the severity and urgency of each issue identified and present practical, prioritized recommendations. This detailed reporting not only supports accountability but also helps the organization focus its efforts where they are most needed to reduce risks and improve safety outcomes.
The final phase of an OHS Internal Audit involves follow-up and implementation of corrective actions. Each identified issue must be assigned to responsible personnel, along with specific timelines for resolution. Ongoing monitoring ensures that corrective measures are effectively executed and maintained over time. In some cases, a re-audit or verification step is necessary to confirm that the implemented changes have successfully addressed the root causes and that the system continues to improve.
Benefits of OHS Internal Audits

One of the most significant benefits of conducting an Occupational Health and Safety Internal Audit is the improvement in overall safety performance. Through regular audits, organizations can proactively identify hazards, unsafe practices, and system weaknesses. By addressing these issues before they lead to incidents, the likelihood of workplace injuries and accidents is significantly reduced, creating a safer environment for everyone.
Another key advantage of implementing an Occupational Health and Safety Internal Audit is ensuring legal and regulatory compliance. Health and safety regulations vary across industries and countries, and staying compliant is essential to avoid penalties and sanctions. Regular audits help organizations stay up to date with current legislation, identify areas where they fall short, and take corrective action before violations occur.
A well-executed OHS Internal Audit also contributes to cost reduction. Preventing workplace incidents leads to fewer workers’ compensation claims, lower insurance premiums, and minimized operational disruptions due to accidents. These financial savings allow companies to reinvest in safety improvements, training, or other strategic areas of the business.
Beyond financial and regulatory benefits, an Occupational Health and Safety Internal Audit enhances employee engagement. When staff members observe that management is genuinely committed to creating a safe work environment, it builds trust, boosts morale, and encourages active participation in safety initiatives. Employees become more likely to report hazards, suggest improvements, and follow protocols consistently.
Finally, conducting an OHS Internal Audit helps strengthen an organization’s reputation and credibility. A strong safety record reflects responsible management and operational excellence, making the company more attractive to clients, investors, and potential business partners. It shows that the organization values its workforce and takes corporate responsibility seriously.
Conclusion

An effective Occupational Health and Safety Internal Audit serves far beyond the basic function of ensuring compliance. It acts as a foundational element of a proactive occupational health and safety audit process, enabling organizations to continuously identify hazards, close compliance gaps, and improve operational procedures.
In the context of an occupational health and safety audit in Morocco, where both national legislation and global standards are increasingly emphasized, internal audits play a vital role in strengthening the overall safety management system.
