Operational Planning and Control for ISO 45001 Workplace Safety

ISO 45001 Clause 8.1 - Operational Planning and Control

ISO 45001 Clause 8.1 covers how you plan, implement, control and maintain the processes needed to deliver the OH&S management system in practice. It pulls together hazard elimination, the hierarchy of controls, management of change, and the work needed to keep day-to-day operations safe.

The clause has three parts in the main body of 8.1 - General (8.1.1), Eliminating hazards and reducing OH&S risks (8.1.2), and Management of change (8.1.3). Procurement (8.1.4) is covered in a separate article. UK organisations operating under HASAWA, the Management Regulations and the various activity-specific sets of regulations (PUWER, COSHH, Working at Height, etc.) will already have many of these controls in place - 8.1 is the framework that brings them together.

What Clause 8.1 Asks For

8.1.1 General - plan, implement, control and maintain the processes needed to meet the OH&S management system requirements and to put the actions from Clause 6 into effect. Set criteria for the processes, control them in line with those criteria, keep documented information enough to have confidence work is done as planned, and adapt work to workers. Where multiple employers share a workplace, coordinate the relevant parts of the management system with them.

8.1.2 Eliminating hazards and reducing OH&S risks - establish, implement and maintain a process for eliminating hazards and reducing risks using the hierarchy of controls, in this order: eliminate the hazard, substitute with less hazardous processes or materials, use engineering controls and reorganise work, use administrative controls including training, and finally provide adequate PPE.

8.1.3 Management of change - establish a process for implementing and controlling planned changes that affect OH&S performance, including changes to workplace location and surroundings, work organisation, working conditions, equipment, and the workforce. The process must also handle changes to legal requirements, changes in knowledge about hazards and OH&S risks, developments in knowledge and technology, and the consequences of unintended changes - taking action to mitigate adverse effects as needed.

The Hierarchy of Controls

The hierarchy of controls in 8.1.2 is not just a recommendation - it is the order the standard requires you to apply. PPE is the last line of defence, not the first. UK case law and HSE guidance reinforce the same principle. When auditors review your controls, they look for evidence that elimination and substitution were considered before engineering, administrative or PPE controls were chosen.
