An Occupational Health & Safety Management System (OH&SMS), defines the framework in which the organization cares for the occupational health and safety of its employees. It represents a set of rules, policies, processes, plans and practices for preventing occupational health and safety hazards and minimizes risks in the workplace. OH&SMS is unique for every organization and it must be adequate to the legal requirements, occupational health and safety hazards and business processes applied in the organization. ISO 45001 represents the best practices in establishing, implementing and maintaining the OH&SMS. Its requirements and guidelines help an organization to establish effective OH&SMS and to avoid missing important elements along this way.
