● Forcible entry5Enter 171 at fireeng.hotims.comThis is especially necessary at strip stores and row taxpayer fires.Several roll-down gates may be present; they can span acrossseveral storefronts. Because of mushrooming and migration intothe exposure occupancies, smoke may be issuing from behind allof the gates, and the exact location of the fire may not be evidentfrom the street. In this case, reports from the roof team and companiesin the rear can assist in pinning down the exact location ofthe fire. In addition, a thermal imaging camera (TIC) can be usedto discern which gate has the highest amount of heat behind it.Once you determine the exact location of the fire and whichgates need to be opened, size up the gates themselves. Whattype of gate is it? What types of locks does it have? Are theremultiple locks? Are the locks engaged? Is the gate manually orelectrically operated? What is the quickest way to gain entry?Once you have the answers to these questions, you can beginforcible entry operations.Enter 172 at fireeng.hotims.comREMOVING THE PADLOCKSMost often, the fastest way to gain entry through these gatesis to remove the padlocks. This is also the preferred methodbecause it allows the gate to be raised intact to completelyclear the opening. Size up the locks as well. Check to see ifthe locks are attached to the pins. Sometimes the locks arein place but the pins are not. Also, the pins may be in place,but they may not be inserted into the channel rail and gate. Inaddition, if locks with long staples are used along with shortpins, you may be able to pull the pin out of the pinhole in thegate without removing the lock.You basically will find a standard or a circular type of padlockduring the size-up. Standard padlocks are portable or detachablelocking devices that consist of a lock body and movableU-shaped staple. The lock can be regular or heavy duty. Regularpadlocks have a staple that is one-quarter inch or less in diameterand lock on only one side of the staple. Heavy-duty padlocks(case-hardened steel) have staples with a diameter larger thanone-quarter inch and may lock on both sides of the staple—known as “heel and toe” locking (photo 6). These padlocks canbe operated by keys or numerical combinations, and they areavailable in a wide variety of shapes and sizes.As the name implies, circular padlocks have a circularshapedlock body and are often protected by circular steelguards that are welded to the channel rails. These locks areextremely difficult to access and usually cannot be forced by104 March 2012 FIRE ENGINEERING www.FireEngineering.com
6or a rope attached) to the body of thelock. The chain can then be tensionedso that the lock is in a parallel positionand held steady. You can also use thepike end of the halligan to steady lockswith long staples by placing the pikeend through the staple. Once the lock issteadied, position the saw blade so thatboth sides of the staple will be cut. Aswith any metal-cutting operation, beginwith a low revolution per minute (rpm)on the saw until a groove is started inforcible entry ●the staple; then increase to full rpm tocomplete the cut through both sides(photo 8). Once the cuts are completeon all of the locks, pull out the pins, androll up the door. If no other means areavailable to steady the lock, pin the lockitself up against the channel rail with thesaw blade, and cut.Some truck companies carry a toolknown as the “duck bill” lock breaker.This tool is quite effective in removingpadlocks if a saw is not available. Place7the same methods used for standardpadlocks. Some common circular padlockbrands are the following:• Abus Disc.• American 2000 or “hockey puck”(photo 7).• Master 6271 series.• Master 736 series.• Brinks R70.• Locks by other manufacturers thatare similar to the Brinks and Abuslocks.Usually, the quickest method forremoving padlocks is to cut the lockswith a saw equipped with an aluminumoxide or diamond-segmented blade. Ifpossible, these locks should be held ina stable position before cutting begins.You can accomplish this by clampinga pair of locking pliers (with a chainwww.FireEngineering.comEnter 173 at fireeng.hotims.com
