Adopting a systematic approach to casualty care allows life-threatening conditions to be rapidly identified and managed. The principles of interoperability apply to casualty care; fire and rescue services should plan and prepare where appropriate with the ambulance services and other partner agencies in their area, to deliver a good level of care for casualties involved in the incidents they attend. Improvement and development should be identified as a priority in continuing to provide the best level of care for a casualty.
The medical resources may require the assistance of personnel to gain access to the casualty. They may also require assistance with the transportation of equipment and the casualty.
If the casualty is in a remote location, this may need to be reflected in the medical resources required, as there may be a need for specialist skills and equipment.
Personnel should adopt the appropriate approach, depending on the number of casualties. A single or last casualty present should be treated and stabilised with the appropriate medical care, with the intention of transportation to a hospital. For further information about dealing with multiple casualties, refer to Carry out triage.
If there are any safety concerns about the presence, number or condition of casualties, first responders should consider if this may be due to exposure to hazardous substances or chemical, biological, radiological or nuclear (CBRN) materials. If there is the potential for these to be affecting casualties, the guidance provided in  Hazardous materials – Signs and symptoms of exposure should be followed.
It may be necessary to request medical resources as a precautionary measure, for the safety or treatment of emergency responders at the incident.
