“4 Day OHSAS ISO 45001:2018 Lead Auditor” is a competency-based four day course that focuses on the role of an auditor in leading teams for an audit of a management system using ISO 19011:2018 Standard Guidelines to evaluate the level of conformance of organizational OHSMS processes against the requirements of the ISO 9001:2015 Standard. The course builds upon the knowledge gained from “3 day Internal Auditor” course and augments the understanding and intent of guidelines of the ISO 19011:2018 Standard related to leading audit teams. It explains the roles, responsibilities, functions and accountabilities of a lead auditor – from audit initiation stage through the audit follow-up stage – with the use of real life case studies applicable to various business and industry sectors. The auditing approach can be applied for leading internal audits, supplier audits, customer-initiated audits and accreditation/certification audits. This course covers competencies OH (2 day occupational health & safety), AU (1 day auditing) and TL (1 day Team Lead), which can be taken consecutively or simultaneously.
