Direction may need to be given to people inside or on top of a vehicle to remain in place, to ensure that the vehicle remains stable. This will allow personnel to initiate appropriate stabilisation and anchoring before the occupants of the vehicle are requested to move.
Anchoring a vehicle will reduce the likelihood of it moving and reduce the risk of harm to emergency service personnel, members of the public and persons trapped inside the vehicle. The effectiveness of stabilisation should be regularly assessed and reviewed, with adjustments made to the stabilisation methods being used if required.
When anchoring a vehicle, consider the affects any method of securing the vehicle will have on the rescue of casualties, for example, securing and anchoring around the door pillars may restrict the doors when they are required to be opened as part of any rescue plan.
