Video

Just imagine being in ground zero amidst a whole 16 acres of dusty hellscape with low visibility, in which you can just see the silhouettes of twisted hulking ruin, and you hear HUNDREDS of this alarm all around you, some near, some far, coming from all directions. And you know that with each one lies a dead fireman.

Wait I heard this in teardown

I've heard that's what those alarms were in the comment section of a 9/11 video. Know i know for sure. I think it makes the sound worse knowing what it actually is

Hope to never hear that many alarms ever again.

my dads friend was searching through the rubble, he heard 100s of those alarms and he knew what they were, he is still haunted by sept.11.2001

Sick echo!

I remember trying to go inside the etc but the observation was not open but then the whole building shook knocking us down couple minutes later before south tower plane we saw a lady badly burnt but i still pray for her and all those today the jumpers were just so heartbreaking even though i don’t know them I still have empathy something i think about every now and then but its America now that will never be forgotten or the same sept 11 2001 💐🌹🇺🇸

This sound is horrifying. The sound that everyone heard on 9/11. Rest easy, everyone.

That sound is bone chilling.

the sound a firefighter never wants to hear

Rip to all of those firefighters in 9/11 😔

WHO WEARS FLIP FLOPS IN A FIREHOUSE??!!?!

Jesus saves

Such an annoying and ear piercing sound but I know it means well and is helpful. Kind of sucks you have to move the SCBA pack around every 30 seconds to avoid setting that off. My Chief would bury me within 5 seconds of that thing at full chirp.

This sound hurts my heart,I’m in firefighting training and everytime it comes on it just makes me feel all sad because of how many times I’ve heard it when fire fighters pass

How could that system be repaired, in case the alarm go off? Need circuit please

0:23 Pass Alarm. Chicago Fire Firehouse 51.

My dad is a firefighter and he said his former captain was working on 9/11 and when he got to the mountain of rubble, he looked into the dark abyss and heard tons of those alarms, but no movement nor voice. To this day, anyone who accidentally sets off their PASS device will trigger him badly

Another worthless fucking video You guys are horrible about explaining anything about anything… I don’t want to watch you work, explain to me what things do and show me how to Turn off this fucking pass device

Lovely Video clip! Excuse me for chiming in, I am interested in your opinion. Have you ever tried - Rozardner Lucky Interview Reality (Sure I saw it on Google)? It is a smashing exclusive product for firefighter interview tips without the normal expense. Ive heard some extraordinary things about it and my best friend Jordan finally got amazing success with it.

Is that varna illinois?

What is the SCBA and why is there a alarm

I heard this sound a fire scenes I’ve been on I run towards this sound no matter what

0:23

Hello ;) what do I have to buy just to get the sound and siren? What pass alarm? Thanks ;)

I don’t know why some FDNY members have this as their ringtone. It’s not a sound that you want to hear. Small brains, I guess.

RIP All those who have fallen

God damn hearing that noise on all the footage from 9/11 makes my heart hurt

When I hear this I instinctively shake my butt for some reason

9/11. Those towers. The bad memories. Oh god no

this was the sound that was heard on 9/11 after those building fell and around ground zero...a sound that represents dead or injured firefighter.

I’ve always wondered what those beeps were whenever I watched videos from 9/11. I honestly thought it was fire alarms that were from the buildings. To find out they were actually to signify that a firefighter is dead, and to hear so many of those in sequence just sends chills down my spine.

For some weird reason this calms me

Hook it up 2 an amplifier and annoy the hell out of your neighbours

Our truck sound like the alarm when we start them up

I remember being 3 on 9/11 and seeing and hearing that sound in the news footage of firefighters o2 alarms going off, everytime I hear it, I start crying.

First sounds like a Mockingbird and the second sounds like a cricket.

Is that full straight pipe

That saved my life and many others

i seen a joke on facebook. somthing about firefighter twerk = the dance the fireman uses to keep his scba pass alarm from going off... can spmbody explain this to me? why it goes off when you stand still?

At 17 in my dept you are a full member. I have gone to fire emt and rescue school. Only restriction is not being able to go into an active structure fire, but you are most definately a contributor to the scene

what is the deference between the scott 2.2 scba and the 4.5 scba

that sound is burned into my brain and when ever i hear it all i think is 9/11 with all the debree and thinking that that sound is fire fighters down and not moving and i can still remeber everything from that day.

you need something in the back

Same, also being an FF it makes my ears and my senses perk up whenever I hear one or anything that sounds like one

when i watched alot of 911 videos of when both towers fell all you heard was this and 343+ other alarms all in sequence. it was pretty weird. now whenever i hear this i get shivers down my spine.

I agree on red lights being better for ff's. N nj blue us for ff n cops r b/r

@dynastar666 wrong. well somewhat. at 17 your just as trained as an 18 year old. in pa you can't run lights til your 18. a lot of departments let you respond at 16 and some even 14 so it all depends on the department. if he/she started at 14 by now he/she is probably more trained than an 18 year old.

@dillybar1997 yes thank you lol, so many guys here have told me about it.

@kameronbc21 Yea in Chicago we used to have Scott but after 9/11 we switched to the Msa firehawk the msa is indeed better.
