The manhole fires happen because of a very old electric system that in place under the road and that is the reason why the man holes go on fire like that from time to time.
The gurgeling sound is from water boiling in the manhole. When enough water turns to steam & evaporates it exposes the network cables to “pop & burn” (blowing shorts). N.Y.C. is fed in a vast interconnecting network of mains (secondary voltage 110/208 3 phase). The “fuses” (current limiters) in the network have to melt to stop the catastrophic meltdown. This is all caused by a combination of road salt & melting snow/ice. In combination with deteriorating electric cables sitting in a corrosive bath. Eventually the water seeps into the connections causing the cables to breakdown electrically. The temperature increases due the mounting resistence of the cables to the point that they overheat. Enough heating & the cables start to fail causing a rapid succession of other cables to fail. The end result is a manhole fire. Manhole covers “fly” when there is enough expanding pressure trapped inside the vault & can’t escape. The pressure keeps expanding until it can’t release except though the 200 pound steel lid. Hence why it flies.
1:12 why is the purple k unit and HM1 not 10-86 1:48 and also why is the foam unit not there this call is a 10-86 and a 10-25 4:38 water and electricity DO NOT MIX 8:51
It’s amazing how much we don’t see that’s under the streets in nyc I myself I’m amazed and I live in Vermont where every town has a volunteer fire department of course all the personnel have had fire training with diff. Schools they attend .but when comes to the city it’s a hole different ball game!!! And for you that goes to these fires you be careful ware a yellow vest and be safe. Please.!
Well that was a sparkling video John thnx, going to be a nice job to repair that pfft.
THANKS SO MUCH! ;o)

Hey enjoy all your videos keep up good work and Iam a volunteer firefighter in Wisconsin
SUPER COOL AND THANKS SO MUCH! ;o)
I am a firefighter not for NYC but all firefighters are not supposed to spray water on high voltage lines above or underground.
THEY DID! I GOT THERE AFTER THEY WERE DONE. THANKS SO MUCH! ;o)
They turn off the power to those lines first. Lol
That was very interesting, great one JJ
THANKS SO MUCH! ;o)
Thsnks! Do you know if there are any pictures from inside this manholes in the www?

YUP!
Awesome footage my friend! 😉
THANKS SO MUCH! ;o)
Awesome Coverage!
THANKS SO MUCH! ;o)
You Get The Best On Scene Footages Of Fires
THANKS SO MUCH! ;o)
nice great work
THANKS SO MUCH! ;o)

YES, I AGREE GARY! EVERY AREA IS DIFFERENT AND THANKS SO MUCH.....
All your Videos is Nice!!
THANKS SO MUCH! ;o)
Very nice! ;)
THANKS SO MUCH! ;o)
Wires burning? Not methane?
A LITTLE OF BOTH. THX.
How does that happen. Seems like it's not uncommon ?
It's because New York City has underground electrical systems and they short out sometimes which causes manhole fires.
IT HAPPENS A LOT CAUSE MANY OF OUR CITY'S WIRES RUN UNDERGROUND. THX.
Great catch John, looked very scary when the manhole blew.
YES AND THANKS SO MUCH! ;o)
I wish more videos were longer like an hour or more instead of 18 or 20 seconds
OK.
if it is a electrical fire way is it not making a poping sound?
ELECTRICAL.....
Sounds like bombs being dropped!
A LITTLE.
Gurgling at 18:25 and Eruption at 18:48!
YES.....
What is burning electric wires?
YES, THAT IS WHAT IT IS.....
Black smoke coming out 🚒🇺🇸
YUP!
💪💪💪💪💪
THANKS SO MUCH! ;o)
That’s gotta smell terrible, I hate electrical fires, probably the worst smell in the world
IT DID! THX.
