What is a key focus of investigators when attending to a fire casualty?

A key focus of investigators when attending to a fire casualty is maintaining fire and flooding boundaries. This is essential because ensuring that fire and water do not spread beyond controlled areas helps to manage the situation effectively and prevents additional hazards. By maintaining these boundaries, investigators can safely conduct their operations and protect lives as well as property while determining the cause and impact of the fire.

Maintaining boundaries also aids in controlling the scene, allowing rescue operations and investigations to proceed without interference from environmental factors or further incidents, thus ensuring that evidence is preserved for later analysis. This objective supports the overarching goals of damage control and incident management, which prioritize safety and effective response to emergencies.
