Control measure Establish appropriate cordon controls
Control measure knowledge
Incident commanders must consider the safety of firefighters, members of other agencies and the public. They have a duty, so far as reasonably practicable in the context of operational requirements, to ensure that people are not put at risk by fire and rescue service activities and that anybody exposed to serious and imminent danger is informed of the hazards and the control measures necessary to protect them.
The fire service has the power to restrict the access of persons to premises or a place in an emergency and establishing cordons is an effective way of maintaining safety and controlling resources.
Where practical, the police will establish and maintain cordons at appropriate distances to allow the emergency services and other responding agencies to save life, protect the public and property, and care for survivors.
In some areas the police will have agreements enabling the fire and rescue services to manage gateways into the inner cordon, establish who should be granted access and keep a record of people entering and exiting.
Cordons can be divided into distinct areas:
An outer cordon may be established around the vicinity of the incident to control access to a wide area. This will allow the emergency services and other agencies to work unhindered and in privacy. Access through the outer cordon for essential non-emergency service personnel should be by way of an access control point.
The police will usually control outer cordons, and may also establish traffic cordons to prevent unauthorised vehicular access. The police will identify safe routes in and out of the cordon for emergency vehicles and other agencies. Rendezvous points and marshalling areas will usually be located within the outer cordon.
Figure 4: Where practical the outer cordon should be identified by using blue and white barrier tape.
The inner cordon controls access to the immediate scene of operations and provides an increased measure of protection for personnel working in that area. Incident commanders should restrict access to the lowest numbers needed for safe and effective operational activity. At small incidents this could be an existing physical barrier or a safety officer briefed to restrict access.
At incidents where a higher degree of control is required, those entering the inner cordon should report to a designated scene access control point and register their arrival. This ensures that they can be safely accounted for should there be any escalation of the incident, and affords an opportunity for briefing about the hazards, control measures, emergency arrangements and other issues. Nobody should be permitted to enter the inner cordon without an appropriate level of personal protective equipment (PPE). It is necessary to ensure that those leaving the inner cordon register their departure.
The fire and rescue service will be responsible for safety management within the inner cordon until responsibility for the scene is transferred to another body. Overall responsibility for the health and safety of personnel working within the inner cordon remains with individual agencies. Such agencies should ensure that personnel arrive at the scene with appropriate PPE and are adequately trained and briefed for the work they are to undertake within the cordon.
At certain incident types, for example hazardous materials, working near water and Marauding Terrorist Firearms Attack (MTFA), there may be a need to divide cordons into hot, warm and cold zones. This will depend on the level of risk faced by emergency service responders and the range of corresponding control measures identified and implemented.

Some hazards may present such a significant danger to the safety to firefighters, other agencies and the public that no control measures will adequately reduce the risk. Incident commanders should consider establishing an exclusion zone within the inner cordon to which access is denied to all personnel, including emergency services.

Further information on cordons can be found in the Cabinet Office document Emergency Response and Recovery.
- Have a policy for limiting access of personnel to the highest risk areas of an incident ground and for briefing and identification of those involved. This policy should include any procedural guidance and such equipment/resources necessary to implement it safely
- Agree roles and responsibilities for establishing and controlling access to cordons with partner agencies
- Agree with partner organisations appropriate procedures for briefing other agencies working within inner cordons under the safety management of the fire service
Ensure that appropriate inner and outer cordons are established, identified and communicated following an assessment of risk to crews, other agencies and the public
Control access to the inner cordon using methods proportionate to the size and complexity of the incident
- Establish a scene access control point to log all persons operating within the inner cordon when appropriate
Implement exclusion zones where intolerable risks to safety are identified
Request the police to establish a traffic cordon where necessary
Request an air exclusion zone through the appropriate authority if required
