Control measure knowledge

An assessment should be made of the weight of the object and its stability. How it has come to rest and the topography of the incident scene may contribute to its potential movement. The object should be taken into account when determining the methods being used to stabilise the mode of transport.

It may be possible to relocate objects away from the hazard area, without affecting the stability of the mode of transport or worsening conditions for any casualties. Carrying out this activity may improve the access to and egress from the mode of transport for emergency responders and casualties. If objects are relocated, their original position should be recorded for investigation purposes, and their new location chosen so that they do not impact on the handling of the incident.

If the object involved has an electrical supply, such as street lighting, the appropriate operator should be contacted so that they can isolate the electricity. For further information refer to Utilities and fuel: Adopt defensive tactics until the electricity supply is isolated.

Heavy objects that have landed on modes of transport, such as trees or structures, will probably require the assistance of fire and rescue service specialist teams, or external specialist resources to remove them. Specialist resources could include:

  • Local authorities
  • Building engineers
  • Tree surgeons
  • Urban search and rescue (USAR)
  • Transport network teams

Strategic actions

Fire and rescue services should:
  • Consider providing appropriate equipment for lifting and moving objects from transport networks

  • Understand how to request National Resilience assistance for the urban search and rescue (USAR) capability for lifting and moving large or heavy objects

  • Establish arrangements with organisations and companies that are equipped to move large and heavy objects

Tactical actions

Incident commanders should:
  • Assess the weight of the object, its stability and its impact on the mode of transport and any casualties

  • Establish cordons that take into account the potential movement of the mode of transport and the object involved

  • Request specialist resources for the stabilisation or removal of the object involved

  • Prior to moving any object involved, record its original position and identify a suitable new location for it

  • Employ appropriate stabilisation methods for the mode of transport to limit the impact of the movement or removal of the object involved
