Gas, electricity and water services may be affected or damaged as a consequence of any structural collapse. This can create the potential for leaking gas, localised flooding and/or exposed electrical services. Isolating services must be considered in the early stages, along with liaising with the appropriate agencies to provide advice and assistance. Equal consideration should be given to the possible need to keep certain services functioning to aid in resolving the incident. The list of utilities will depend on the building; a hospital, for example, may have piped steam and/or oxygen. Unusual services such as these must be identified in the Site-Specific Risk Information (SSRI) and this must inform the incident commander's decision.
