Transport incidents require the implementation and management of appropriate cordons to protect the public, emergency responders, other agencies and contractors from hazards, prevent escalation of the incident, preserve the scene for investigators, define the safe working area and assist with command and control.
In addition to the information that usually informs appropriate cordon controls, transport incidents may present other factors.
- Air incidents
- Aircraft size and type
- Aircraft engine hazard zones
- Evacuation slide path areas
- Aircraft armaments
Also refer to the control measure – Cordons: Military aircraft
- Rail
- Incident may be linear in nature over an extended distance
- May be appropriate to position staging posts, marshalling areas and command facilities inside or alongside the cordon
- May be beneficial to link cordons with sectorisation
- Multiple access and egress points will require careful management of cordon controls
- Cordons may have to include management of railway crossings
- Road
- Road vehicles could contain prisoners or detainees
- Road vehicles could contain livestock or other animals
Also refer to the control measure – Cordons: Moving vehicles on roadways.
- Waterways
- Cordon controls may need to be supplemented with a designated boarding control point if a vessel is involved
- If personnel are boarding a vessel from a port or dock, a dockside safety sector may need to be included
