ISO 45001:2018 establishes the requirements for establishing, implementing, maintaining, and improving an Occupational Health and Safety Management System. The main purpose of ISO 45001 is to provide a framework for identifying and managing occupational health and safety (OH&S) risks in the workplace. It includes the whole process from planning through to implementation and operation, taking account of the relevant provisions for each stage. The goal of ISO 45001 is to reduce OH&S risks, not only by legal compliance but also by prevention. iso 45001 singapore
