Hazard Unstable ground
Knowledge and understanding
Understand all associated hazard knowledge
In this guidance, sudden collapse or the failure of unstable ground can be attributed to adverse weather conditions or naturally occurring erosion that has undermined the integrity of the ground, so that it can fail without warning. The presence of unstable ground after a partial building collapse should also be considered.
Through knowledge pooling between various agencies and information sharing in local emergency planning groups; fire and rescue service personnel should be aware of specific areas within service boundaries where there is a risk of failure from unstable ground.
Involving specialist fire and rescue teams (such as USAR and line rescue) and other emergency services or appropriate resources should be considered.
