How a Fire Engine Works

[@animagraffs]

VIDEO CORRECTIONS (compiled from viewer comments): From user "Mike Gasking" 4:28 It is possible to have a 3,000 GPM pump (or even more on an industrial pumper for a refinery, etc.) but it would be uncommon on a pumper like this one, it would be more commonly 1,500gpm these days From user "SpartacusColo": 7:11 SCBA's are filled with breathing air: the same ambient air we all breath. They are not oxygen tanks. Please add your comments to this thread to help others learn accurate info!

[@animagraffs]

From user "Ryan Wood": Boosters are usually only 1 inch and the crosslays go from 1.5” to 3” but 3 is Usually used as supply. The deck gun can not create a head barrier. Radiant will go right through it. It’s why water curtains are no longer a thing. Also the reason we don’t go in with a master stream is that it will steam us out and hurt us because there is no control on how it disrupts the thermal layer of the fire.

[@thomasstuart2936]

The standard ladder complement on an Engine (as opposed to a Ladder or Rescue truck) is usually one 24' extension ladder, one 14' roof ladder (with roof hooks) and one 10' folding or "attic" ladder. Often this will be complemented with a 17'or 22' "Little Giant" style ladder. The 24' and 14' ladders are rated to 750 vertical pounds, more than twice that of standard ladders and can be used for bridging gaps. All Ground ladders are tested annually to ensure they meet NFPA standards.

[@thomasstuart2936]

While you mention that 1500 gpm is the common flow, you neglected to state that the full flow rating is at 150 psi pressure. Pumps are certified at the factory for full flow at 150 psi, 70% flow at 200 psi and 50% flow at 250 psi. These flows are tested and re-certified annually. Primer devices on the pumps are rated for 21" of vacuum.

Been a firefighter, driver engineer for 14 years. Love the old Q too. The air horn and Q are controlled by a foot pedal from either driver or officer side of our engine. Our engine is all manual, no electronics on our operator panel. This video is pretty modern, looked like a universal storz fitting in front driver compartment. We draft alot and do shuttles from tankers, not many fire hydrants here. When we draft a real pond we use a large screw on strainer. Great video!!!

I’m watching this after just having checked off a fire truck just like the one in the video. I’ve got to say, as someone who drives one of these for a living, you’ve nailed this video. The animation, the terminology, the descriptions and uses. This video was actually spot on with how a fire truck really is, even down to the individual tools. Not to mention you talking about the different fire extinguishers, a small detail but a thorough one you did. Fantastic job with this video, and all the research that has to go into it!

[@thomasmcmahan2014]

Edit: I will say one thing that needs clarification, the SCBA tanks/air packs are just plain air and are not oxygen. The bottles are filled with the same air you breathe regularly, and not pure oxygen.

@@ENGSTROM79 From the point of view of tradition, he was right to leave it out of the gear bay. The device, invented by a fire captain, had to be custom made. Although now purpose-manufactured, the halligan is still a personal purchase, and the firefighter will have it in cabin. I saw an excellent irrodescent halligan on the hands of one of our local aerial crews. Progressive as the department was, he admitted that he had to buy it himself.

Retired Payson FF/EMT. Very good job on this set up. Every department, even every Engine can be set up for different types of tasks. Some areas might have their apparatus carry more Wildland gear during the Summer months. Some also carry foam for hard airport landings. My Engine EP 121 at station 12 right by the Payson airport. We had to have AFFF on board, plus because we were a Paramedic unit, we had to have one compartment strictly for medical calls. We had to rig up a heating pad in that compartment to keep the IV fluids warm in Winter. We also had to keep backboards, KED devices, MAST pants. Our apparatus all had 5' supply hoses. Not fun to lug around after a fire when you feel like you been through Hell and back. God I miss it!!!

Great video! I'm a german firefighter and I'd love to see a video of a german fire truck (best choice would be an HLF) I can already tell you some things: German fire trucks are usually packed with a LOT more eqipment, therefore have smaller water tanks (in our station both LF and HLF carry 2000l of water, and 150-200l extinguishing foam) In germany, every fire truck with a pump has it on the back. The crew cabin reach from 6 to 9 seats, 6 is called a ''Staffel'' and 9 is called a ''Gruppe". In our station, LF and HLF both are Gruppen-vehicles, one driver, one officer/group-leader and 3 troops of 2 firefighters with each troop having their own task. The design of the vehicles is also different of course

Awesome video . Great detail was put into this . A bit more to add . Of course this is a standard engine so it doesn’t have everything but I know that in the video it neglected to say we almost always carry a pair of what we call the “married irons” or flat head axe and halligan , as well as we typically carry chocks for the wheels of the truck or for a vehicle accident where the cars on its wheels ( even tho we don’t always use them in either scenario ) . Safety vests , a cooler filled with ice and water sometimes and spare SCBA bottles also . And I may have been confused but near the end when you were talking about the hose size you mentioned us carrying 1 1/2 , I don’t know anyone in America that uses that size , we use 1 3/4 . A booster line is an 1 in I believe , you also got 2 1/2 for the big boys . Those are all attack lines . Not to mention the view you showed was the supply hose which is 3in and 5in variety , the length and amount was accurate tho but the sizes felt off .

Crosslays and the jumpline at my department are 1 3/4 inch hoses. Our pumpers also have 5 inch and 3 inch supply lines in the hose bed, as well as a rear discharge with 2.5 inch hose. But most pumpers are widely configurable when being built.

[@deathraylabs_nature]

I cannot believe how consistently good these videos are. amazing work!

[@bobszabo7387]

The rebreathers ( or long duration scba) are usually used in a cooler enviornment such as work in a tunnel. The air you rebreathe tends to be warmer ,warmed by body heat. The standard scba bottle has a duration of 30 minutes, if you aren't working. a more realistic duration is usually about 15-20 minutes ( speaking from 40 + years experience ). Also as the air decompresses it cools. So you are breathing about 60 degree air regardless of the surrounding temperatures ( as high as 500 degrees for a short time in a structure fire interior attack). This does help to keep you cool as you work. I've seen bottles breathed down in as little as 10 minutes, usually by rookies in their first time in training and the bottles will actually ice up on the bottle.

[@wyskass861]

Great video as always. To add, in larger cities with more equipment, the fire "engine" will have less structural entry equipment and more hoses so be more specialized since there also be "trucks" which are used for resque and building entry. The engine operators are tasked with delivering water, while the truck people finding people and dealing with structures. There are also ladder trucks which extend their trailer configuration ladders and can hook up to water from the engine. Smaller departments will need to do more of the job off one vehicle more like this one.

I enjoyed this video. It was well thought out from an instructor sense and did not get "in to the weeds" with specifics or details. We could really go deep with specifics and exact PSI ratings and GPM but that isn't what this video is meant to convey and there would be 100+ varants of this animation. It is a struggle and balance to build a training model and storyboard it while trying to keep variations "generalized" to not put everyone to sleep. Thanks for sharing!

I don't know if this is a standard thing or it's just my FD but on our trucks pretty much the entire driver's side of the truck with the exception of the last compartments are all water related. Couplings, nozzles, hydrant tools, pretty much anything that will aide in water or water delivery. The passenger side compartments are exclusively fire fighting equipment. I've also never seen a hard wired mic and speaker like that next to the pump panel. We use either standard radios that are attached to our person or headsets that plug into the truck (We only really use them with our stand-on pump panel trucks. Also never seen a truck where the helmets attach to the roof like that. If that's something newer trucks are doing thats pretty cool. Really good video though and great attention to detail.

[@jakewebber4567]

To get more specific on the “Q” siren: The most common type of mechanical emergency siren is the Model Q2B, made by Federal Signal corporation. The way it works, is an electric motor spins an impeller inside a stator at a very high rpm. The stator has a specific number of holes. The more holes, the higher pitch of a tone the siren has. (on the Q, I believe it’s 16), and the impeller is shaped to cover those holes simultaneously. The centrifugal forces from the high RPM spinning causes a vacuum effect, pulling air in and through the holes, in which the impeller “slices” the air. It’s the same principle that applies when you talk through a fan. There’s literally thousands upon thousands of makes and models, with the Q2B being only one of literally numerous different models from Federal Signal alone.
