Final answer:
A firefighter arriving at a scene where a type 2 structure is on fire needs to determine the collapse zone. They consider factors such as the size and condition of the structure, presence of hazardous materials, and extent of the fire. The collapse zone is determined based on evaluating the structural integrity and identifying signs of instability.
Step-by-step explanation:
In regard to determining the collapse zone, a firefighter arriving at a scene where a type 2 structure is on fire needs to consider several factors. A collapse zone is an area around the burning structure that could potentially collapse, posing a risk to the safety of the firefighters and anyone nearby. When dealing with a type 2 structure fire, which typically includes commercial buildings, the firefighter should take into account the size and condition of the structure, the presence of any hazardous materials, and the extent of the fire.
In general, firefighters determine the collapse zone by evaluating the structural integrity of the building. They look for signs of instability, such as cracks, bulges, or sagging, that may indicate structural damage and potential collapse. They also consider the risk of secondary hazards, such as gas leaks or electrical hazards, which can increase the danger of collapse.
Once the collapse zone is determined, the firefighter will establish a perimeter around the area to keep people at a safe distance and prevent them from entering the zone. This ensures the safety of both the firefighters and the public.
