Most of the management system published by ISO (International Organization for Standardization) works on the principle of plan, do, check and act, which is normally referred as the PDCA cycle. This particular thinking has brought a revolution in manufacturing and service sectors. The PDCA concept is an ongoing activity to continually improve the organization. ISO 45001 is also based on PDCA thinking.
The nucleus of all activities and phases in the occupational health and safety management system is the role and commitment of the top management i.e. the Leadership that is driven with worker participation and involvement in the occupational health and safety management system. The leadership is the clause 5 of the standard.
As clearly seen from the PDCA process flow in the above illustration, external and internal issues along with the needs and expectations of interested parties influence the plan phase of the occupational health and safety management system. The “Plan” phase in OH&S management system is the 6 clause i.e. planning in the standard. In the planning of the OH&S management system, risks and opportunities are determined and assessed. Based on risks and opportunities, OH&S objectives are established. Moreover organization develops processes necessary to deliver intended result that is compliant with OH&S policy.
In the “Do” part of the OH&S management system, operational controls and processes identified in plan phase are implemented. This “Do” part varies with the organizational size and processes. An organization has to identify support functions and operational controls for management system based on the complexity of the processes and hazards involved within those processes.
It is essential to look for the mandatory documentation required by the ISO 45001:2018 standard.
In the “Check” part, activities, organization measures and monitors processes and operational controls against the occupational health and safety management system’s policy and established objectives. Internal audits and management reviews are also part of the check phase of the management system.
Finally organization goes in the “Act” part where results and outputs of management reviews, corrective actions on nonconformity, and other measures are taken in order to continually improve the performance of occupational health and safety management system.
The cycle is again repeated in terms of reassessment of risks and opportunities, and accordingly identification of new or modified processes for change in risks or opportunities. Then implementation of the defined modified or new processes. Overall modified processes and operational controls are then verified in monitoring and measurement i.e. check part of the PDCA cycle. Ultimately again actions are taken and the cycle is reiterated again and again for continual improvement.
