What is a five alarm fire?

A five alarm fire is a classification used by fire departments to indicate the severity and level of resources needed to combat a fire. It is one of the highest levels of alarm, indicating a large-scale fire that requires a significant number of firefighters and equipment to contain and extinguish.

The term "five alarm" refers to the number of alarms or additional units that have been requested to respond to the fire. Each alarm level corresponds to a certain number of units or firefighters that are called in to assist in fighting the fire. Typically, a five alarm fire will involve multiple fire departments, aerial ladder trucks, and additional support services such as EMS and police.

Fires that reach the five alarm level are often large, fast-spreading, and difficult to contain. They can pose a significant threat to nearby buildings and residents, as well as to the firefighters working to control the blaze. Due to the intensity and complexity of these fires, they require a coordinated and strategic approach to prevent further damage and ensure the safety of everyone involved.
