"What is an offensive versus defensive fire?"
Recent, highly publicized structure fires in our area have brought up an important distinction in how firefighters operate at structure fires.
An offensive fire means firefighters enter the building to search for occupants and attack the fire from inside. This can only occur when conditions are survivable and enough trained personnel are available. At an absolute minimum, an interior attack generally requires two trained firefighters inside, two trained firefighters outside as a backup for the interior crews, and someone manning the pump panel maintaining a reliable water supply for those inside.
A defensive fire means that conditions are too dangerous for firefighters to enter. Crews attack the fire from outside using hand lines, master streams, and aerial ladders while protecting nearby buildings and preventing the fire from spreading. This approach is used when structural collapse is possible, the volume of fire outguns the number of available crews, or the risks of entering outweigh the potential benefits.
The decision between offensive and defensive operations is not unique to Mission. It is a standard fire service decision based on fire conditions, building stability, available water, staffing, and overall safety.
As an all-volunteer department, we may initially arrive with only a few members depending on the time of day. On weekends, many of our members could be out of town grocery shopping just like you. During weekdays, they could be working their full-time jobs. A fire, especially one involving several apartment units, can easily require 12 to 15 trained firefighters (or more) to safely begin an effective offensive operation based on the sheer size of the incident.
Defensive firefighting does not mean crews are standing around or giving up. It means the building is too dangerous to enter. Firefighters continue fighting the fire from outside while protecting people and nearby buildings.
More trained firefighters on scene means more options. When enough trained members respond, crews may be able to enter the building and fight the fire from inside. When too few firefighters are available, the department may have no safe choice but to fight from the outside.
Every new member helps make our department stronger. If you are ready to learn new skills, serve your friends and neighbors, and become part of a dedicated team, Mission Volunteer Fire & Rescue encourages you to consider joining the department as a recruit.
