Regardless of the type of door, a few basic rules always apply. (4)
Try before you pry
Don't ignore the obvious
If possible, use the door that the occupants normally use to enter/exit the premises
Maintain the integrity of the door
Continue size-up as bldg comes into view. Determine: (3)
Location of fire
Any visible victims
Door to be used for entry (usually front)
Look at the locks. How many and where? This will tell you:
Where to place your tool
If no hinges available, then:
no hinges = stop the rabbits
Stop molding will be present OR
Frame will be rabbeted
Deciding factors for the most appropriate method of forcible entry: (4)
Need for speed

Tools and personnel available (last factor/least concern)
Degree of damage entry will create
Cylinder farther from edge than 1-3 inches:
Serious attempts at security
- different method of attacking door
-- through the lock, power tools, hydraulic tools
-- look for easier way in
Pattern of ______ coming through the door indicates presence of _________, similar to those used by cavalry to lock front gates at forts.
Bolt heads (police="supporting bolts").
Halligan and flat-head: Most experienced person should be on the ________.
When using pronounced bevel on fork (halligan), position fork so _______ curve is towards the door and _____ curve is toward the jamb.
Through-the-lock usually indicated by: (3)
-light fire condition
-specific types of doors OR
-specific types of locks
Narrow-stile door facts
Through the lock OR attack hinges (top first - adze), break glass/break push bar as last option.
A "stile" is the frame of a door
1 1/4 throw
Fox lock facts
Rectangular plate in center of door w/2 sets of supporting bolts.
-attack 3 bolts, leave on to swivel out of place
-top, bottom, top.
-use lock puller, Sunilla, or adze/claw of halligan (NO K-TOOL!).
-unlocked turns towards lower set. (Square).
-3/4 in. bars, as much as 2 in. into doorjamb
Through the lock used when:
Emergency of very minor nature
-police (usually not detectable)
-fox (plainly visible)
-pivoting deadbolt (plainly visible)
When NOT to use "through the lock":
Visibility seriously affected
-HFT is solution
*injuries when visibility is poor=conventional entry*
-less fatigue (more air/less injuries)
(8,000 psi/5 in claw/25 lb (old) 9 lb (new)
Solid door in steel jamb (inward doors).
Doesn't work well on doors that open out or flimsy/hollow doors in wood jambs (opt for conventional)
Rod size and jamb depth for Mul-T
1/2 in. in diameter and as much as 1 1/2 inches into jamb
Through the lock.
The real heart of the operation begins when?
Once the cylinder has been removed
The simplest type lock to conquer is the:
You encounter a SQUARE shaft instead of a flat shaft when you pull the cylinder, you have encountered a ______.
4 wood screws and a 1/2 in. thick steel bar extending down to a recess in the floor
Firefighters seem to have the most difficulty with these locks because of unfamiliarity.
Little pear-shaped cam and limits area where it can work, only about 180 degrees of its path. Must use a key tool with a 90 degree bent end. What kind of lock?
Mortise: The design of these cylinders results in their greatest force being in the _______________, from the _______ position is where the cylinder does work.
Straight down position.
5-7 o'clock position.
First step in attacking fox lock is to ____________.

They are personnel multipliers and great firefighter safety devices
In serious fire situations, ______ should be the OVERRIDING CONCERN.
Need for speed
HFTs works for (4)
HFT effective when a serious situation involves: (3)
Rapidly spreading fire.
*not to be used everyday*
Gates are classified as: (3)
_____ and _____ gates are the most common and simplest to force.
If you find a Mul-T-lock engaged, you have three choices:
Find the key.
Find another way in.
Destroy the $2,000 door.
Where to cut on Mul-T-lock door?
Triangular-shaped hole in the lower half of the door, on the side between the lock cylinder and the doorknob
Often faster and less expensive to repair if you:
Break through a cement-block wall than if you force this type of door
Fastest means of gaining entry with Mul-T-lock?
Using circular saw with metal cutting blade
On a ________ gate, the raising/lowering chain is usually shielded by a piece of angle iron, secured by padlocks in addition to the locks on the gate itself.
On ________ gates, you must remove either the gate key or the slide bolt before you can open the gate.
Padlocks fall into two categories:
Low and high security
Small bow (less than 1/4 in. in diameter) and are not case hardened.
They aren't usually found on security gates since they are easily forced.
May be cut easily with bolt cutters or you may force them with a halligan or a claw tool.
Low security padlocks
Bows of case-hardened steel at least 3/8 in. thick.
Usually a formidable hasp is welded to the frame.
Case-hardening (metal treating process) gives the steel great compressive strength.
Must use 36 in. cutters.
Power saws and cutting torches are highly effective.
Axe always starts
(Great compressive/poor shear strength)
Ways to split bow of padlock
Duckbill lock breaker.
Cut down miners pick.
Fastest means of forcing multiple locks is by using:
Power tools, either oxyacetylene or oxy-MAPP gas torch.
Circular saw with aluminum oxide blade
Any lock cut above _________ are best cut with a torch.
Proper procedure for cutting metal with saw
Place blade in work and then slowly increase the rpm of the saw until it is operating in the cut.
____________ is a unique type lock, resembling a shiny steel hockey puck. The locking mechanism and hasp are entirely concealed behind the body of the lock. Pipe wrench and cheater bar or saw or torch for cutting lock (cut across, 2/3 of the height of the lock, away from key way)
American Lock 2000 gate lock
On gates, clutch can be found:
Second chain or cable hanging alongside the first
Two disadvantages to cutting metal gate/roll up doors
Takes longer to make 12 or 15 ft cuts than two or three locks.
Almost all cuts only open part of the door or gate
Two conditions that usually indicate the need to cut the door:
Heavy fire conditions where it is important to get water on the fire.
A door that can't be readily opened by normal means.
(Mechanical override normally on inside of door)
Two style of cuts to cut doors/gates
Inverted V (teepee).
What type of cut?
First cut at head height, diagonal.
Second cut at diagonal, don't overlap first.
Too small for access.
What type of cut?
Preferred method of cutting doors that you intend to enter.
First cut close to edge of door from max height.
Second cut, close to opposite edge.
Third cut in center, down about 2 feet
*same amount of cuts as Inverted V, but guarantees larger area*
If the gate is _____________, you can slide out the remaining sections of slats
(Surface Slide Section Slats)
With three-cut, hanging sections can bind. You can avoid this by:
Making additional short (2 foot) cuts approximately every 5 to 6 feet.
Structures differ from abandoned buildings in that they have an owner.
Protection from "urban miners".
Some of the most difficult forcible-entry and vent challenges.
Simplest is window covering with sheets of plywood held by 2 x 4 bracing on inside with 3/8 in. bolts.
To defeat HUD Windows, attack:
Braces-striking, bottom first. Someone holding window.
Bolts-cutting with bolt cutters through 3/8 in. bolts
When cutting HUD Windows, 2 prerequisites to be safe and successful:
Steady platform to work from (not from ladder).
A way to prevent the covering from falling uncontrollably.
When using circular/chain saw on HUD Windows:
Metal cutting blade a45 degree angle to covering, slicing through bolts just behind the head.
If wood blade, triangular cuts completely around bolt head, cuts must overlap.
If chainsaw, vertical cut above top brace to below bottom brace.
Variations of HUD Windows
Sheet metal cladding (earliest)-circular saw, no chainsaw.
Stucco covering (worse)-no chainsaw.
Vacant property security (VPS) system (newest)-plastic sheeting or lexan, metal-cutting saw, 40 lbs each
Burns at more than 5,000F.
Special hollow steel rod that burns while pressurized with pure oxygen.
Cuts through heavy steel bar, large I-beams, train rails or 1/2 in. (or thicker) plate.
Throws a large jet of sparks and flame on downstream side.
Exothermic torch or burning bar
Best way into locked building is:
By using the key
Keys arranged in duplicate on different locks on different doors.
Must be manipulated in series
Locks that engage the jamb ________ or ________ are great challenges to conventional forcible entry.
More than 1 in.
At multiple points
Once the cylinder is removed, the first step is to ___________.
Pick up the cylinder and examine it.
This will indicate the TYPE of lock you are facing, which TOOL to use next and even WHERE to use it
Most efficient way to remove lock cylinders is to use:
When breaching inward opening door with forcible-entry tool, place the tool:
Nearly parallel to the door at about a 15-20 degree angle from the door
The halligan provides _______ of getting a bite on the work.
Four different means
Conventional forcible entry is often called:
The brute force method
Thinking persons forcible entry
Use back of wrist to test door. Two advantages:
Speed-don't have to stop and put your glove back on.
Exposing a nonessential part of your body
Forcible entry size up begins:
With alarm information
*time of day often indicates the need for forcible entry*
Type of occupancy can also tell you:
Which way the doors open
99% residential open inward, opposite for comm'l and places of assembly
When going into class 1 buildings, the axe can be replaced by:
8 or 10 lb sledgehammer
When confronted with forcible entry, consider following factors:
Need for speed (serious situations-overriding concern).
Type of door and lock assemblies (deciding factor).
Tools and personnel available (least concern).
Degree of damage that entry will create (consistent with degree of danger).
When forcing a door inward, the wedge will spread the door but the task remains of pushing the door. This is usually possible when the fork end has been driven in ________ past the end of the door.
1 or 2 in. past the end of the door
When forcing an inward door, beside with the claw end, it is sometimes useful to use the _________ between the door and the jamb. Then pushed the forked end towards __________.
Controlling the door: (3)
Short piece of rope.
Simply holding the doorknob.
Inward opening doors.
If you are forced to breach the hinges, you should start with the __________
Top one first
Although many locks are __________ with complex arrangements, a locks key cylinders are ____________.
Very simple mechanical devices
May only have secondary lock as security.
How to check?
Only secondary, then what?
Knife blade or credit card under to feel for bottom rod.
If no rod, attack secondary conventionally or through-the-lock.
