In today’s competitive business environment, maintaining a safe workplace is crucial. ISO 45001 helps organizations systematically improve their OH&S performance, ensuring compliance with legal requirements and fostering a culture of safety. This standard not only protects employees but also enhances organizational reputation and efficiency.

Core Elements of ISO 45001

Understanding Occupational Health and Safety (OH&S)

Auditing Principles and Techniques

Audit Planning

Effective audit planning involves defining the audit scope, objectives, and criteria. It also includes preparing an audit plan, selecting audit team members, and scheduling audit activities.

Conducting an Audit

During the audit, the lead auditor collects and verifies information through interviews, observations, and document reviews. This process involves assessing compliance with ISO 45001 requirements and identifying areas for improvement.

Reporting and Follow-Up
