ISO 45001 Internal Auditor

Course description

The IECB Certified ISO 45001 Lead Auditor training course equips you with the skillset required to conduct occupational health and safety management system (OH&S MS) audits. This course is built upon ISO 45001, which replaces OHSAS 18001 and serves as the first global standard for OH&S MS.

This course emphasizes the significance of proficient internal audits, enhancing your knowledge and skills to orchestrate and execute an OH&S MS audit in alignment with the ISO 19011 management systems auditing guidelines and ISO/IEC 17021-1 certification process.

Practical exercises are a vital part of this course, designed to reinforce key aspects of an OH&S MS audit: comprehension of ISO 45001 requirements, understanding of audit principles, utilization of tools and techniques for evidence collection, leading an audit team, engaging with auditees, reviewing documented data, drafting nonconformity reports, and compiling the final audit report.

Upon successful completion of the course, an exam follows. Passing the exam earns you the "Certified ISO 45001 Lead Auditor" credential, which substantiates your professional abilities and certifies your aptitude to audit an OH&S MS in accordance with ISO 45001.
