When coordinating an interior fire attack, what factor must be considered first?

When coordinating an interior fire attack, the first factor that must be considered is controlling utilities. This is essential because safely managing the utilities, such as gas, electricity, and water, helps to mitigate hazards that could complicate firefighting efforts. If these utilities remain active during the attack, they could pose significant risks to both firefighters and occupants. For example, unaddressed gas lines can lead to explosions, while live electrical wires can cause electrocution.

Controlling utilities ensures that these potential hazards are neutralized, allowing for a safer environment for fire attack operations and facilitating effective firefighting efforts without the added dangers these systems may present. It establishes the groundwork for a successful interior attack and protects both the rescue teams and the building structure itself.
