(NC #5)
In serious fire situations, which of the deciding factors should be the overriding concern – whether to save a life or cut off fire that is rapidly extending:
The need for speed
Ch. 8: Norman – Forcible Entry
(NC #6)
In most cases, however, ___ will be the deciding factor:
Type of door or lock assembly
(since certain types are best opened using specific methods & is some cases, there’s only 1 way to get past a specific door)
Ch. 8: Norman – Forcible Entry
(NC #7)
In almost all cases, the degree of danger posed by f/e should be consistent with:
The danger and damage from the hazard, usually fire
(Bad PR to break $1k door to shut down faulty boiler & don’t waste time/effort going through lock when fire is burning away into door)
Ch. 8: Norman – Forcible Entry
(NC #8)
The factor which should be of least concern in most cases when forcing entry is:
The availability of personnel and resources
Ch. 8: Norman – Forcible Entry
(NC #9)

Halligan-type tool + flat head axe or sledgehammer.
Ch. 8: Norman – Forcible Entry
(NC #10)
Regardless of what type of door you encounter or the method you choose – a few basic rules should always apply. The 4 rules are:
- Try before you pry.
- Don’t ignore the obvious.
- If possible, use door occupants normally use to enter/exit.
- Maintain integrity if door.

The occupants normally use to enter or exit the premises.
Ch. 8: Norman – Forcible Entry
(NC #14)
Rule 3: If possible, use the door that occupants normally use to enter/exit the premises. This puts you ___ (where) and also makes your job a lot easier:
In their most likely exit paths
Ch. 8: Norman – Forcible Entry
(NC #15)
Rule 3 (cont): If we can find the door that the occupant normally uses, chances are that it will be (less or more) heavily secured than other doors, and we can duplicate the actions of the occupant.

The oxygen supply to the fire
Ch. 8: Norman – Forcible Entry
(NC #19)
Rule #4 (cont): In serious cases, the sudden inrush of fresh air can set off a:
Backdraft explosion
in less serious cases, fresh air may intensify a smaller fire
Ch. 8: Norman – Forcible Entry
(NC #20)
Rule #4 (cont): Even if a charged hoseline is in place, breaking through the door isn’t the best idea, for if the line loses water – door can’t be:

Ch. 8: Norman – Forcible Entry
(NC #21)
Rule #4 (cont): At interior doors that expose ___, it is critically important to keep the door to the fire intact. Why:
- Stairways or vertical openings.
* Since the closed door may be all that is keeping fire from blowing up the stairs being used by ffs or occupants.
Ch. 8: Norman – Forcible Entry
(NC #22)

What often indicates the need for forcible entry:
Time of day
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #27)
The type of ___ can tell you which ways the doors will open:
Occupancy
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #28)
About 99% of residential doors open (inward or outward):
Inward
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #29)
About 99% of residential doors open inward. Whereas the opposite is true of:
Commercial establishments and places of assembly.
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #30)
Knowing which way doors likely open can help you review:
- The method of attack the door,
- Which end of the tool to use,
- What tool to use.
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #31)
Although the ___ (tool) is great compliment to halligan in most bldgs, it does have some drawbacks.
Flathead axe
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #32)
Flathead axe is great compliment to the halligan in most bldgs - does have drawbacks. The 6 lb doesn’t give it great driving force when used as hammer. When going into Class 1 (fire resistive) bdlg, axe can be replaced with?
- 8 or 10 lb sledgehammer
- (don’t need to chop wood in such bldgs & the added impact of the sledge is very useful on substantial steel doors or a cinder block wall)
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #33)
F/E Size-up continues as bldg comes into view (started w/ alarm information). Determine location of fire, any victims & door to be used for entry (usually front). While approaching door, look around – 3 Q’s to ask self include -
- Does fire appear to be in close proximity to the door? (if so, prepare for worst).
- What type of door is it? (wood, aluminum, steel clad, glass, etc – wood gives, making task easier.)
- What is the jamb set in? (brick, wood, other material)
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #34)
Look at the locks – how many are there and where are they. This will tell you:
Where to place your tool
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #35)
In some cases, seeing ___ may tell you to find an easier way in:
Several substantial locks
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #36)
Look at the presence of hinges or stop molding. If you see hinges, the door opens (which direction):
Out – towards you.
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #37)
If no hinges are visible, ___ will be present or the frame will be ___.

Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #38)
Be aware of how doors open and what that means. Normally apartment doors open:
Inward
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #39)
Doors that open out to the all (in apartments) include (2):
Janitor’s closets and elevators
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #40)
Doing the visual size-up of the door takes only a matter of seconds & you can do as you approach the door. Once you actually reach the door, the first rule is:
Try before you pry.
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #41)
Try before you pry. Before grabbing the door knob and pushing the door open. Makes sure everyone is ready to proceed. There can be fire a lot of fire behind a door with very little evidence on the outside – ensure everyone is positioned how:
- Out of the way – off to 1 side of door,
* At least crouching, if not kneeling.
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #42)
(After all in position) – keep your glove on and bend your hand back while tugging on your coat sleeve to expose a little of your wrist. Using your bare skin, feel:
Feel doorknob then top of door.
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #43)
Using method on previous card to feel door, you gain a lot more than feeling the same areas with your bare hand. Those gains are (2):
- Speed – don’t have to reglove to proceed.
2. Exposing nonessential body part.
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #44)
Burns to the hand are difficult to heal, since ___ hamper proper healing:
Hand motions greatly hamper proper healing.
(your wrist is far less mobile and less critical to daily activities).
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #45)
The doorknob is a good placed to check for heat, since it usually has a ___ connection from the fire side to the outer side:
Direct metallic, conductive connection
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #46)
(CFPC) – if doorknob is hot, then its time to begin the attack. Now grab knob & try the lock. If its locked – give the door a shake to determine:
Where the locking devices are & which are actually locked.
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #47)
Most normal locking devices have a key cylinder located where:
1 – 3” from edge of the door
if notice any cylinders located further than 1 – 3” from edge, it indicates owner made attempts at security
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #48)
If cylinders are located farther than 1 – 3” from edge, security modifications have been made. Options:
- Different method of attacking door - (power tolls, through the lock, hydraulic tools, etc)
- Look for easier way in.
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #49)
Fig. 8-5: A pattern of bolt heads coming through the door indicates the presence of:
Drop bars (similar to those once used at forts)
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #50)
Conventional F/E is often called the _____ method.
Because (its called this because):
- The brute-force method.
* Since it relies on applying great force either to bend or snap part of the door or lock assembly.
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #51)
The person applying the force must know how to get the most out of a lever and:
Fulcrum.
(the longer the lever, the great the force that can be applied – too long of tool will be awkward in confined areas).
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #52)
By far, the most efficient combination of manual forcible entry tools is:
Flat-head axe paired with the halligan tool
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #53)
The Halligan tool provides how many means of getting a bite on the work:
4 – additionally it is invaluable for opening floors, walls, and roofs during overhaul.
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #54)
Since the development of ___, the flat-head axe is used primarily as a hammer to drive the Halligan into spaces where it can get its bite:
Power saws
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #55)
Halligan & axe (often called set of irons) is a 2-person job. 1 to position & hold the Halligan, 2nd to swing the axe. The ___ person should be the one on the Halligan.
More experienced
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #56)
The more experienced FF should be holding halligan – they do the following:
- Place tool in position
- In control of both tools
- Direct other person when to swing
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #57)
When operating this way (2 people with set of irons), make every attempt to have the 2 people work from:
Opposite sides of the tool.
Ch. 8: Norman – Forcible Entry
Section: Forcible-Entry Size Up (NC #58)
Have ff’s work on opposite sides of the tool (if possible) - If axe misses objective, it won’t carry through & strike other person. The 3rd tool which should be brought in to ensure the basic triad of tools present at every structure is?
6’ hook (Fig. 8-7)
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #59)
The actual mechanics of forcing the door opened depend on:
Whether the door opens in or out
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #60)
Inward-Opening Doors → To breach an inward-opening door - place fork end of f/e tool ________ (where) in relation to lock, depending on whether the members are standing or kneeling:
About 6” either above or below the lock
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #61)
Inward-Opening Doors → Placing fork end of f/e tool about 6” either above or below the lock prevents tool from:
Striking the bolt of the lock as it is being driven in – which will stop penetration.
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #62)
Inward-Opening Doors → If there is more than 1 locking device, insert the tool (where):
Midway between them
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #63)
Inward-Opening Doors → When using tools with a pronounced bevel in the fork, position the fork so that the outer curve is:
- Outer curve is toward door &
* Inner curve is towards jamb
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #64)
Inward-Opening Doors → Tool with a pronounced bevel in fork – position with outer curve toward the door & inner curve towards the jamb. This ensures ___ & provides ___:
- Ensures tool not driven into door &
* Provides greater leverage.
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #65)
Inward-Opening Doors → Tool w/ pronounced bevel in fork – position w/ outer curve toward the door & inner curve towards the jamb. Positioning in the reverse manner tends to:
Let to tool back out when force is applied
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #66)
Inward-Opening Doors → Initially, place the tool (Halligan) nearly parallel to the door at about ___ angle from the door. This allows tool to be:
- 15 – 20 degrees
* Allows tool to be driven between door the & molding or rabbeting
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #67)
Inward-Opening Doors → Axe person must never swing w/ out specifically being told to do so, since Halligan will have to be continually moved outward as it is driven in further & further til it approaches:
A 90 degree angle toward the door
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #68)
Inward-Opening Doors → 90 degree toward the angle by halligan is necessary to:
Necessary to avoid driving tool into jamb
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #69)
Inward-Opening Doors → As tool is forced inward, wedge shape of fork will spread door away from jamb. Eventually, space will be wide enough to allow the lock bolt to clear jamb or frame of the rim rock to tear through. Task of pushing door open remains, this is possible when:
Possible when fork has been driven 1 or 2” past the edge of the door
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #70)
Inward-Opening Doors → When fork is driven 1 – 2” past edge of door, the following action will be - Pushing tool back toward door. This makes the doorjamb & halligan act as:
- Doorjamb - acts as a fulcrum
* Halligan - acts as the lever
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #71)
Inward-Opening Doors → Push on far end of halligan to exert the most force. Before applying the force, make sure that:
Someone has control of door so it doesn’t pop open uncontrollably.
(Do this by using a hose strap or short rope, or simply hang on to doorknob – fire may blow out and engulf members)
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #72)
Inward-Opening Doors → Alternate method to driving fork-end of halligan – put adze end of tool between door and jamb. Then __. This can be useful if you lack a ___:
- Push forked end of tool towards door.
* Useful if lack driving tool – not always successful since adze often slips out of jamb.
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #73)
Fig. 8-12: An alternative method to forcing an inward swinging door is to drive the hook or claw end deep into the jamb as a ___: Pushing the fork end toward the door will force door open:
Fulcrum
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #74)
Inward-Opening Doors → At times, it may be possible for a single FF to force a wooden inward swinging door by ___:
Swinging the Halligan like a baseball bat.
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #75)
Inward-Opening Doors → Single FF forcing an inward swinging door by swinging Halligan like a baseball bat – procedure:
- Swing halligan like baseball bat,
- This buries point end of the hook into the wooden jamb,
- Apply force to door with adze end by moving forked end up or down and toward the door.
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #76)
Inward-Opening Doors → When other methods (described) fail – drive forked end between door & jamb, about 6” above or below the estimated position of:
The hinges.
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #77)
Inward-Opening Doors → When other methods (described) fail – drive forked end between door & jamb, about 6” above or below the estimated position of the hinges. After you have driven fork in far enough, you will have:
Pulled the screws out of the door or hinge
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #78)
Inward-Opening Doors → attacking hinges approach – this method should be tried only as a last resort, since it violates:
Rule #4 – maintain integrity of the door
(if anything goes wrong, such as delay in water – there is no easy way to close the door and gain control of the situation)
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #79)
Inward-Opening Doors → For the same reasons as attacking the hinges is not recommended, so is (which technique):
To knock out the center part of a door and crawl through it, leaving the frame intact.
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #80)
Inward-Opening Doors → If you are forced to breach the hinges, you should start with which hinge first? Because?
Start with top hinge 1st
Since heat/smoke/fire will be subsequently venting out – better to crouch below this & work on bottom hinge than to stand in the path of fire venting from below.
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #81)
Outward-Opening Doors → Vast majority of commercial doors open in which direction and why?
- Outward
* Codes require doors open in direction of travel
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #82)
Outward-Opening Doors → Similar principles for inward swinging doors apply to outward swinging – spread door away from jamb & force in direction of travel. Outward swinging doors are often found in:
Recessed walls
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #83)
Outward-Opening Doors → Recessed walls would inhibit the movement of the iron if a fork were used, the recommended method is to use ___ (which end) of the tool.
Adze end
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #84)
Outward-Opening Doors → With the adze end driven in between the door & jamb on lock side, the tool projects back across the door itself. By pulling out on the end of the tool, you apply force to pull out the door. Position of adze is:
6” above or below the lock – same way as fork for inward swinging door.
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #85)
Outward-Opening Doors → Adze end can’t be driven in further than:
The thickness of the door – it hits the rabbeted jamb.
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #86)
Outward-Opening Doors → Since the adze end can’t be driven in more than the thickness of door (hits rabbeted jamb) – wedge affect not as great as w/ forked end. This may be overcome by:
- Prying up or down on opposite end of tool - which spreads door away from jamb.
- End of tool can then be pulled out – which opens door.
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #87)
If encounter difficulty with lock side of outward swinging door, hinge side may sometimes be forced. Procedure:
- Drive fork end above or below the hinge,
- While simultaneously moving adze end toward wall on hinge side – this prevents fork from being driven into rabbeted stop.
Ch. 8: Norman – Forcible Entry
Section: Conventional Forcible Entry (NC #88)
Outward-Opening Doors → As alternative, if power saws are available, it may be possible to cut through hinge with:
- Metal cutting saw/blade or torch – then pry door with adze.
- Be aware that you will violate the integrity of the door & won’t be able to close it again.
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #89)
Through the lock forcible entry was pioneered when and by whom?
- 1960’s
* By FDNY Capt. George Sunilla
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #90)
The through the lock forcible entry method centers around:
Duplicating the action of the key lock
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #91)
Although many locks are sophisticated devices, a lock’s ___ are very simple mechanical devices:
Key cylinders
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #92)
If we can get the cylinder out of the way, we can duplicate the:
Action of the cylinder and open the lock as through we had a key – and relock it as well, if desired.
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #93)
F/E method which often provides the fastest, least damaging and sometimes the only way in:
Through the lock method
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #94)
Through-the-lock forcible entry is usually indicated by:
- A light fire condition,
- Specific types of doors,
- Specific types of locks.
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #95)
There are how many major types of locks?
3
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #96)
Those who remain unconvinced of the effectiveness of the through the lock method are those who have either seen the method: Which is almost directly traceable to:
Fail or take a long time to work.
Such are traceable to the members’ unfamiliarity with the procedures to be followed.
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #97)
The through-the-lock method is also known as:
The thinking person’s forcible entry
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #98)
An example of using the through-the-lock method (on a car is):
Punching the lock cylinder out of the trunk and inserting a screwdriver.
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #99)
The most efficient way to remove lock cylinders is to use:
The K tool
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #100)
Fig. 8-18 → 21: To pull a cylinder with the K-tool, Steps to follow are:
- Place K-tool over cylinder.
- Tap it securely onto cylinder with an axe.
- Insert adze end of halligan & apply downward force to pull out the cylinder (if K-tool was placed on from the top)
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #101)
The orientation of k-tool isn’t too critical & may be adjusted to fit situation. What is important is when halligan is inserted into stirrup on back of tool, force being applied continues in:
Continues in the same direction as when the tool was being tapped on
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #102)
The jaws of the K-tool are tapered into a narrowing channel so that the force is applied in the same direction. If tool is applied from the top and the force is upward (against recommended direction), then the tool will likely:
Slip off of the cylinder
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #103)
Fig. 8-21: The jaws of the K-tool are designed to:
Dig deeper into the cylinder as more force is applied – as long as the force is going in the same direction as the jaws.
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #104)
Fig. 8-21 (cont): The K-tool is the preferred to for removing most cylinders, but it will not work on several, notably which locks:
The fox lock & the Mul-T-Lock
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #105)
Fig. 8-21 (cont): The K-tool is the preferred to for removing most cylinders, but it will not work on several, notably the fox lock & the Mul-T-Lock. The ___ are crucial to actually manipulating the lock mechanism:
The key tools
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #106)
The real heart of the operation begins once the cylinder has been removed. The 1st step is to:
Pick up the cylinder & examine it.
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #107)
The real heart of the operation begins once the cylinder has been removed. The 1st step is to pick up the cylinder & examine it. This will indicate:
- Type of lock you’re facing
- Which tool to use next
- Where to use tool
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #108)
The next tools to use are known as key tools, they perform simple functions, which are:
Duplicating the action of the back of the lock cylinder.
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #109)
When you turn a key in a cylinder, it makes an attachment on the back of the cylinder turn as well. This simple ___ action is what operates virtually all locks:
Rotational
Ch. 8: Norman – Forcible Entry
Section: Through The Lock Forcible Entry (NC #110)
With the cylinder out of the way, we can replace the cylinder with a ___ and turn it, thereby performing exactly the same action:

Ch. 8: Norman – Forcible Entry
Section: The Mul-T-Lock Door (NC #228)
Assuming there are no alternatives, the fastest means of gaining entry through an MTL door is by using a circular saw with a metal cutting blade. The procedure is:
- Cut triangular-shaped hole shaped in lower half of the door on the side between the Mul-T-Lock cylinder & doorknob.
- This allows you to reach in & unlock the MTL as well as any other locks on the edge of the door.
Ch. 8: Norman – Forcible Entry

Head height
Ch. 8: Norman – Forcible Entry
Section: Forcing Metal Gates & Roll Up Doors (NC #290)
Inverted V (aka teepee) cut: 1st cut – make the cut diagonally to one side, as far down as you can possibly go. Procedure for 2nd cut is:
- Begin back at the top,
- Stop several inches short of overlapping the 1st cut initially.
- Cut all the way down on an opposing diagonal,
- Then come back up to the top & cross fully over original cut
Ch. 8: Norman – Forcible Entry
Section: Forcing Metal Gates & Roll Up Doors (NC #291)
Inverted V (aka teepee) cut: On 2nd cut, by leaving the small section intact initially, it helps:
Keep the lower pieces of the gate supported while they are being cut – making the operation smoother.
Ch. 8: Norman – Forcible Entry
Section: Forcing Metal Gates & Roll Up Doors (NC #292)
Inverted V (aka teepee) cut: Once the small remaining section is cut all of the way through, the resulting triangular section of the gate will:
Fold either in or out – allowing access to the area.
Ch. 8: Norman – Forcible Entry
Section: Forcing Metal Gates & Roll Up Doors (NC #293)
Making the inverted V (aka teepee) cut is a fast way to get water on the fire, but has limitations. Limitations such as:
- Opening may be too small to allow Ms easy access to advance a line or emergency escape.
- Provides limited amount of ventilation.
- If a locked door is located behind gate (common), its difficult to force the door.
Ch. 8: Norman – Forcible Entry
Section: Forcing Metal Gates & Roll Up Doors (NC #294)
Inverted V (aka teepee) cut: Sometimes, you can expand this cut the width of the portal. If the gate is surface mounted, the remaining sections of slats can be:
- Slid out from the slat above by grasping them below the top cut
- Remove a slat on each side of cut in this manner
- This frees remainder of gate to be push up (manual doors only), while the bottom slats are pulled out.

One drawback of the inverted V (aka teepee) cutis the possible presence of winds tabs. Wind tabs are:
- Small tabs at end of slats,
* They interlock w/ steel guardrails that comprise the frame of the gate.

Recessed doors and doors w/ wind tabs need different style of cut. 3 cut method: location of cuts:
- 1st – as close to edge as possible with max height to min height
- 2nd – same as 1st on opposite side, within 6 – 8” due to body of saw (same slat!)
- 3rd – in center, from top of other cuts & downward about 2’
Ch. 8: Norman – Forcible Entry
Section: Forcing Metal Gates & Roll Up Doors (NC #305)
At times, especially on wide doors, the weight of the hanging sections can bind the slats that support them – making it difficult to remove them. Avoid this by:
Making additional short (2’ high) cuts approx. every 5 to 6’
(these sections are easier to pull & the operation can be further assisted by M’s supporting the sagging area on the low side – where slats have already been removed)
Ch. 8: Norman – Forcible Entry
Section: Forcing Metal Gates & Roll Up Doors (NC #306)
3 cut method – key point to remember, all cuts must be made through the same slat at the top and bottom. Also helps when removing the slats to:
Push in on 1 side, while pulling out on the other.
(Once 1st slat has been pulled out a little using locking pliers or channel locks or driving the claw of a halligan through the sheet metal – the op can be assisted by a M with a flat head axe tapping only slightly more on the back of the slat)

HUD windows – removing from the outside; extra effort will be required if the plywood covering is:
Nailed to the window frame
Ch. 8: Norman – Forcible Entry
Section: Forcing Metal Gates & Roll Up Doors (NC #329)
HUD windows - removed from the outside by cutting bolts loose from the window. If a circular saw is available, the saw should be used (how):
At a 45 degree angle to the window covering – slicing though the bolts just behind the head.
Ch. 8: Norman – Forcible Entry
Section: Forcing Metal Gates & Roll Up Doors (NC #330)
HUD windows - Circular saw (CFPC): Cut as close to the head as possible, why?
To minimize the amount of wood the blade has cut into – metal blade does not cut wood very well.
Ch. 8: Norman – Forcible Entry
Section: Forcing Metal Gates & Roll Up Doors (NC #331)
HUD windows - Circular saw (CFPC): Once heads of bolts are cut off, may be necessary to use claw of Halligan to drive the remainder of the bolt through the brace and plywood. Be careful when cutting the bolts because:
The weight of the window covering can cause the window to drop suddenly.
(have a FF hold it in place with a tool)
Ch. 8: Norman – Forcible Entry
Section: Forcing Metal Gates & Roll Up Doors (NC #332)
HUD windows - Circular saw (CFPC): An alternative to a saw with a metal cutting blade, a ___ can be used to cut the bolt heads with similar results.

(or use a bolt cutter on the bolt itself)
Ch. 8: Norman – Forcible Entry
Section: Forcing Metal Gates & Roll Up Doors (NC #342)
HUD windows – Exterior Ops: Use caution when cutting through plywood, especially with a chain saw – there may be metal bars or a window framing just behind the covering. If you strike it with a blade or chain, it can:
- Snap the chain, causing injury or
* Create enough kickback to throw the saw operator or put the operator off balance.
Ch. 8: Norman – Forcible Entry
Section: Forcing Metal Gates & Roll Up Doors (NC #343)
HUD windows – Exterior Ops: If there are no power tools available, it takes more effort to use hand tools, but can be done. Procedure is:
- Place adze of Halligan on the surface of outer brace,
- Pound halligan with axe or sledge while working fork end sideways.
- (you can split the wood in this fashion, until you have the bolts free of the outer brace)
Ch. 8: Norman – Forcible Entry
Section: Forcing Metal Gates & Roll Up Doors (NC #344)
