An excellent description of the process for performing vertical ventilation on a light weight truss roof. This video is part of a series created by LACoFD.
1, never trust a truss. 2, stay along the wall as long as you can, 3. Make the cut and get off the roof. 4. If there is flame out the roof, it is already ventilated, stay off the roof.
OV is fun but not practical. I mean if you have a good Engine crew helping you out and are equally at the same speed as them, then yeah I’m sure you can make vent practical.
This is how people get killed, you do this from the safety of the bucket or dont do it at all. Why would you send a crew on a roof that can fail in 5mins?
@@chrisreed3435 im not wrong at all lol, literally every text book says otherwise. Not to mention the corrugated roof can flex if you missjudge your cut. Plus your risking firemens lives for a property that probably doesnt have any life hazard (commercial). Your rolling the dice when you do that, good luck with that.
You are a troll, Its called a training video so why not slow it down to show proper technique, but like i said your a toll this a GREAT training video. And I'm a TRUCK Captain. It's LA CO FD not LAFD you Troll
Percy Brown Captain Brown is correct, remember mr. Firefighter slow is steady and steady is fast. Also for you Cap why is it LA county? Do you guys got other stations outside the city of LA?
@@nicaln5104 two different fire departments. City of Los Angeles is one of many cities withing the County of Los Angeles. LACoFD covers unincorporated parts of the county or with cities that contract out for service. For example City of West Covina has its own fire department. The city next door, Covina, does not and contracts out to LACoFD for service.
Nicolas Navarro Two separate departments. LA City coverS Los Angeles and the surrounding incorporated areas while LA County covers all unincorporated areas of Los Angeles County and contracts with cities throughout the county to provide fire and EMS
Is this a joke? WHAT IN GODS NAME are you doing cutting a lightweight truss roof? Walbaums fire 1978 Hackensack fire late 80s. Do you know how quick this can fail under fire conditions. DONT EVEN CUT THE ROOF!! Everyone on the internet wants to talk about safety on the fire ground. This is so fucking unsafe. DO NOT LEARN FROM THIS VIDEO. Don’t do this. Walbaums 78-6 fireman killed lightweight bowstring truss. Doesn’t matter whether it’s bowstring or not. DO NOT CUT LIGHTWEIGHT TRUSS!!! Fuck!!!
Late reply but came to say this after this popped up in my notifications. And truss roofs like this don't fail in sections, once those nail plates start giving out its a domino effect and the place you're standing is suddenly very very bad. After the 88 Hackensack Ford fire, our dept started to inventory and label all buildings with truss construction. Our vert vent SOP for anything with an identified truss roof is to only do roof ops from the bucket or horizontal vent. Nowadays we don't even bother, we have several high volume fans that can be used for commercial structures. I have noticed that southern cali depts seem to have an obsession with being on the roof, even when it is blatantly obvious they shouldn't be. Recently, LAFD almost learned the hard way about doing roof ops over truss construction on that Boyd st fire. I'm not saying roof ops don't have their time and place, but they need to be used like any other tactic, appropriately. And I'll add that for bowstring we wont even go interior, unless its confirmed to be a small incipient fire, far too many funerals have happened because of those POS.
@@Nervegas1, how do you confirm it’s an incipient fire from the outside? 2, how long did the fire burn in Hackensack before failure? 3, when was the last LODD performing vert vent?
In the FDNY, they call the "7 & L" cut a "7-9-8" cut. Same concept.
How and why have I stumbled upon this?
And why am I actually watching it?
44 years on the job.
7 and L is the ticket. Less cuts

Well if you know. What yor doing. Then. You are OK.

At least they will still have a building rather than a pile of smoldering rubble
I'm am a firefighter I do ventlaion
Wouldn't want your drunk crazy ass on my roof. Maybe hit up grammar school before you go back out on the line
@@hpflyboi it's a little boy. Chill out.
LMAO!!! no you're not. good try

Cory Brown 7520 just because you did a ride along doesn’t make you a firefighter

You're wrong. Lightweight Truss roofs get the ultimate bad wrap. I've vented many, and you have way more time than you think.
