As firefighters sometimes our jobs are going through the door in order to perform our interior fire operations and it is imperative we have an understanding on how to force this type of door should we have no other option or this is our best option for a quick knock on the fire or a rescue effort.

Let’s force the door

All hand tools approach - IRONS - Method 1

Starting on the hinge side, using the Adz end of the halligan, gap/crush the door to gain access to the backside of the door by placing the Adz behind the door and begin prying the standalone pin away. By getting the standalone pin out of the way early on will help with the conventional door pop.
Now, attack the lock side of the door starting with the top pin followed by the bottom pin and pry them away.
From here, once the three pins have been pried away, force the center of the door conventionally.

Please note, this will be time consuming and energy depleting. Have a K-12 or spreaders on hand if need be.

The door should go and entry can be made.

From my experience, these doors have been found mostly on rear pharmacy doors and other businesses with highly valuable goods. The best way to approach these doors is to study their makeup and understand their strong and weak links in order to force them in less time and reduce the amount of strain on the crew forcing the door.

Keep your eyes open and stay diligent out there.

Until next time, work hard, stay safe and live inspired.
