See National Operational Guidance: Incident command - Incident ground safety management
Safe systems of work
Incident commanders should implement safe systems of work identified by service risk assessment, procedures and training. The selected safe system of work should be based on the outcome of a dynamic risk assessment taking account of available resources and competencies.
Having a structure of supervision should ensure that the presence of hazards and identified control measures are communicated and implemented to ensure the safety of those operating on the incident ground. The use of sectorisation and functional roles at an incident should be implemented to ensure an appropriate and effective level of supervision.
