ISO 45001 is the global standard for Occupational Health and Safety (OHS) management systems, offering a structured framework for organizations to identify, assess, and mitigate risks related to employee health and safety. Achieving ISO 45001 certification is a significant accomplishment for any organization, as it helps prevent workplace accidents, injuries, and illnesses. However, the success of ISO 45001 implementation relies heavily on the role of internal auditors who monitor, assess, and ensure the effectiveness of the system.

In this essential guide, we’ll explore ISO 45001 from the perspective of an internal auditor. We’ll break down the key principles, the auditing process, and the core elements of the ISO 45001 standard to provide you with a comprehensive understanding of how to carry out effective internal audits and contribute to the improvement of workplace health and safety.

What is ISO 45001?

ISO 45001 was published in March 2018 and provides a framework for organizations to improve employee safety, reduce workplace risks, and create a safer working environment. The standard focuses on ...
... proactive risk management, leadership commitment, and continuous improvement in OHS performance. It replaced OHSAS 18001 and follows the High-Level Structure (HLS), which aligns with other ISO management system standards, making integration with systems like ISO 9001 (Quality Management) and ISO 14001 (Environmental Management) easier.

Key Objectives of ISO 45001

Before diving into the auditing specifics, it's essential to understand the core objectives of ISO 45001:

• Prevent workplace injuries and ill-health: Establish and maintain a proactive approach to managing OHS risks.
• Compliance: Ensure compliance with local, national, and international health and safety regulations.
• Employee involvement: Engage workers at all levels of the organization to identify and mitigate risks.
• Continuous improvement: Foster a culture of ongoing safety enhancements through monitoring, auditing, and feedback.

Core Components of ISO 45001

ISO 45001 follows the High-Level Structure (HLS) which is consistent across all ISO management system standards. The main components of the standard include:

1. Context of the Organization

Understanding the internal and external factors that impact your OHS management system (OHSMS) is crucial. This includes considering regulatory requirements, industry risks, societal concerns, and organizational culture.

2. Leadership and Worker Participation

Effective leadership and active worker participation are essential for a successful OHSMS. Senior management must demonstrate commitment to safety and allocate necessary resources, while workers should be actively involved in safety decision-making.

3. Planning

A key element of ISO 45001 is planning. This involves identifying health and safety hazards, assessing risks, setting objectives, and developing action plans to mitigate those risks.

4. Support

This includes ensuring that adequate resources (financial, human, technological) are available, that employees are properly trained, and that communication channels are open for safety-related matters.

5. Operation

The operations component involves implementing the safety measures identified during the planning phase, including risk controls, emergency preparedness, and ensuring ongoing management of changes in the workplace.

6. Performance Evaluation

Monitoring, measuring, and evaluating the effectiveness of the OHSMS are key to ensuring it achieves the desired results. This includes conducting internal audits, management reviews, and measuring performance against established safety objectives.

7. Improvement

ISO 45001 emphasizes continuous improvement. It’s not enough to simply comply with regulations; organizations should seek to improve their OHSMS by identifying non-conformities, correcting issues, and preventing their recurrence.

The Role of an ISO 45001 Internal Auditor

Internal auditors are integral to ensuring that an organization’s OHSMS is working effectively and continuously improving. They assess compliance, identify risks, verify the effectiveness of safety controls, and ensure that the organization adheres to ISO 45001’s requirements. The role involves more than just checking for compliance; auditors should also look for opportunities for improvement.
