Incident commanders should be aware of the type, number and disposition of emergency fire vehicles and personnel in their own and in nearby service areas, and should have a working knowledge of the responsibilities and capabilities of other category 1 and 2 responder agencies they may call on for assistance.
Relevant personnel should have a thorough knowledge of the capabilities of available resources to ensure they select the correct resource for the incident. They should also be aware of those that could be requested to help minimise the number of responding resources and personnel needed to deal with that particular incident. Their knowledge of the risks in their response area will be supported by regular visits and deployment planning, enabling incident commanders to assess the additional resources required at an incident.
Incident commanders should begin assessing the need for additional resources as soon as they are mobilised to an incident. The assessment should be based on the number of calls received, information received by fire control rooms, visual indications en route and knowledge gained on visits and through pre-planning, which may give indications of required resources.
