Halligan Bar Physics

Forcible entry physics for the entry-level firefighter

[@godzillasauris]

I’m not even a firefighter and I found this video incredibly enjoyable

[@zwenkwiel816]

as a burglar I concur

[@videogamegang1797]

It shouldn’t be funny. But it is. I got into a full belly laugh twice.

[@travisahicks]

Yeah pretty interesting video. Very useful tool.

[@unkwm128]

Same

[@IMKINDOFABIGDEAL13]

I’m not a fire fighter but I do own a halligan. Found it on a job site I was working on. I am a contractor. This thing has been incredibly useful.

[@jasonlizotte4007]

Hey guys, I just randomly came across your video and I am very impressed with it. I am an old timer who has gotten out of the job after many years but it is so encouraging to see young people learning good skills and also taking a role in teaching others. Look forward to seeing your other videos. Never stop learning and be safe on the job guys!

[@cossack814]

Thank you for your service, fireman. I’m an EMT and I want to become a fireman.

[@maestrovso]

You would only need to bring a dinner fork to breach my flimsy front door.

[@keanuchungusmode9453]

This guy is smart! One of the best videos for conventional forcible entry I have seen.

[@ksspang]

randomly watched this because I'm curious about the halligan bar, but for a very low-budget type production, this was very well done! I was especially impressed with how you didn't really stumble or hesitate, you spoke clearly and confidently and didn't waste any time. great work!

[@BostonTransplant1]

Nice intro to forcible entry. Clear, helpful and confident instruction.

[@philips3825]

While initial thanks would go to @adamsavage for introing the Halligan to us internet geeks, the gratitude to the folks who put their lives in danger to save ours is immeasurable. Thank you for such an informative video, showing the amazing work that firefighters do.

[@jmannUSMC]

Not even a firefight but I find this extremely interesting!

[@ericnowlin9945]

Great vid, quick and to the point while touching base on the important stuff

[@jakesigalmix]

Its 4 AM and somehow I found myself here, while I may never use one of these at least now I got an idea of it. Would watch more.

[@burstofsanity]

This by far the most interesting and informative fire fighter video I've watched that I'll never need to use.

[@kb9drh]

Good job to my brother and sister! The irons are my favorite tool. It is truly a versatile tool. Keep up the good work and most importantly be safe and always keep in mind the task at hand.

[@eliastamim2319]

Loved this video please do more!!

[@NorthwoodsShooter]

Us LEOs are now having to learn and utilize these types of tools. This was such a clear and concise video that even coppers who know nothing about this tool or technique prior to watching, would gain knowledge from it. This would make a great roll call video!

[@Xx233xX]

Just don’t pick up the nozzle and spray from the door. Kills the light that could be used to search and steam burns to possible victims.

[@ravenbarsrepairs5594]

Too bad..... LEO's don't need to know how to break into houses.

[@MrMosiz]

If you respond to a fire as an LEO, do NOT break windows unless there is a confirmed rescue

[@sandyschannel6917]

That was very informative and a very clear easy to understand presentation

[@coen555]

Really interesting and cool. Good work guys!

[@xxxvertigoxxx]

Very clear video, great job.

[@l.w.c.2519]

Great video guys!

[@gherkinavoider4452]

80% of my training as a recruit is online. Watching videos on how to become a competent firefighter. This video highlights how important practical firemanship should be prioritised over the bullshit I’m getting. Cheers lads 👍👍

[@praack4563]

yeah - nice video- i remember using an original Halligan- they came out to the station demonstrating it when it was first coming out. man this was a lifesaver. memories of being irons and truckie.. oh and Hygiene Barry>? gotta be a story there.

[@sclars]

Great video, I learned some new stuff, greetings from Germany

[@chris_tophe_r]

great video

[@conqueringlion420]

Thanks Conan

[@TheWtfnonamez]

Brilliant.

[@nathanwright5757]

"Go open palm, so you don't crush your knuckles." Grabs bar with closed fist and pushes... oops.

[@nazahlisboa]

Muito bom,eu sou bombeiro aqui no Rio de janeiro Brasil e uso bastante essa ferramenta.

[@Adantehand]

Halligan! Where are my scissors?

[@mersenniusprime]

I opened this video to look for this comment. May our weird little cult permeate the internet.

[@Dempdawg11]

Setting the door looks like the bottom firefighter is in great danger being eye level with that tool

[@kristinaF54]

Didn't show how to or when to use the spike tool. I heard it's for breaking locks, is it true?

[@Thomasnmi]

I remember using a Kelly Bar

[@FewerNebula]

Pov you just got back from watching Halloween kills

[@brenthemphill6496]

how did you get the 13.5:1 MA?

[@cadena06]

Quick tip when you are hitting from the one knee position try to put the opposite knee down so that you have more room to swing.

[@1683clifton]

get the irons! awesome. adam savage sent me

[@907MTB]

What’s the formula calculation for forks with bevel to jamb versus bevel to door? I don’t understand the .25 difference. Thanks.

[@somma4697]

Please tell me this is a joke

[@62Cristoforo]

The difference depends on whether you’re left or right handed and to a lesser degree on the Coriolis effect, but they’re about the same.

[@MisterTomcat]

Mechanical Advantage = Output Force ÷ Input Force (Resistance Force ÷ Effort Force) or Mechanical Advantage = Input Distance ÷ Output Distance (Effort Distance ÷ Resistance Distance)

[@Show_My_Name_Not_My_Handle]

"it helps to go open palms" *doesn't go open palms* Great video though. Right to the point. I'll almost certainly never need this information, but, it never hurts to know. Plus, hey, maybe my yappin' will get it to the eyes and ears of someone who _will_ use it via YT's algo-magic. (Edited for typo.)

[@zfjames]

Amazing video but CATCH THE DOOR my friend if possible

[@RickDrift]

Halligan was my great grandpas Last name.

[@Malidictus]

I don't quite follow why the spike needs to be at 90 degrees to the adze? Wouldn't it work just as well with both on opposite ends of the shaft with the forks rotated 90 degrees so neither gets in the way?

[@brandonseyfried1251]

Having the 90 degree offset is like adding an additional tool. It gives you a striking surface to utilize the spike as a lock breaker. It also allows the adz to be used with full mechanical advantage on onwards opening doors by penetrating a wooden or hollow metal door frame with the spike and, using the spike as the pivot point, allow body weight to pull down on the shaft of the tool to force the door face inward; usually just above the bolt location. Works great on institutional buildings like schools or dorm rooms with metal door frames set in masonry and solid wood or metal doors.

[@Malidictus]

@@brandonseyfried1251 Hmm... Wouldn't moving the pivot point farther away from the adze reduce mechanical advantage by creating a larger arc of movement? I do see what you're saying, though - that's not something I'd considered.

[@62Cristoforo]

Where can I buy one of these tools in Canada? I’d like to carry it in my trunk, just in case.

[@savagebuilder4264]

Online they're not sold in store

[@zfjames]

Get ready to pay a loooot of money

[@NorthernBuffalo]

Lots of book smarts but just lacking the real world experience. This kid is a great teacher and given some years of real world experience he’ll be a wealth of knowledge

[@pat8988]

9:00 Do as I say, not as I do. 😅

[@williamryder9785]

re do the sound

[@brunothehumble]

there it a fault to the way you're teaching to make the gap. the positioning of the firefighter when prying down on the haligan puts them in a potential bad spot if the haligan pops loose of its bite. that spike aiming directly at the firefighter is a real concern and needs to be mentioned. the idea of training is to put an individual in a position of muscle memory and not needing to think about the potential of catching a six inch spike in their chest if they slip. beyond that pretty solid video.

[@johnlocke_1]

@9:10 "inward swinging door, we're pushing in so have open palms for knuckles do not strike the door. You sure did not take your own advice.

[@DWhite-el4ih]

Why is this guy 19 years old lol

[@domenics2285]

Bring your kid to work day?

[@62Cristoforo]

IK,R? Bonus points for the passion and dedication to his craft. I actually learned something.

[@andromedahavice9478]

What is the point of closing the door immediately after the 10% search? If you're breaking into a door, isn't the whole purpose to allow ingress?

[@ryanpye]

Leaving the door open adds oxygen, which generally speeds fire growth and likely changes the flow path of the fire towards you. (This building is implied on fire in this scenario.)

[@davidphillips1911]

Or you can just call the lock picking lawyer...... Or let the cops hit it with some 12g slugs while you kick your feet up and relax....

[@yetidodger6650]

12 year old firemen.

[@danielwallace7844]

You have some good info but a lot of bad info too.

[@Pizza_Is_Cool]

Not going to elaborate at all?

[@danielwallace7844]

@@Pizza_Is_Cool Sounding or striking inward swinging doors is beneficial (residential and commercial) . Shock loading the screws and components of the door helps loosen or break them. Striking the adze in to gap an inward swinging doors is not wasted time or effort. Especially if it keeps the tool from slipping out. If a strike is what you need to set the tool properly then do it. If gapping the door with the adze breaks the small wood door stop out of the way good. You can't beat a nice open gap especially when forcing a door by yourself. Getting the tool set in properly in the door is never a waste. Also always set the forks in with the inside of the forks to the jamb with the crotch of the forks even with the inside of the door stop. Shocking or striking outward swinging doors is not beneficial because it will only set the door deeper into the frame. When forcing metal doors if your tool catches the lip or seam and the end of the tool ends up inside the door don't start over. You will end up catching the lip again in a different spot and peeling the door in half. Either use the adze to strike inside the door to bend the back panel away from the jamb or slide the forks in behind the rest of the door and crush it in.

[@grizzlycountry1030]

Got rookies doing training videos? 😂

[@STRIDER99r1]

Your mechanical advantages are all wrong. Not trying to call you out but you are spreading misinformation. Mechanical advantage is a measure of the force amplification achieved by using a tool, in this case a lever. The mechanical advantage of a lever is the effort arm length divided by the load arm length. FORMULA MA= effort arm distance ÷ load arm distance. So in your example using the forks on a 30" bar; burying the forks to the crotch (5") leaves you with a 25" effort arm (lever) and 5" load arm. 25/5= 5:1 mechanical advantage. Not trying to call you out but we need to make sure we are spreading right information to the new generation of firefighters.
