Reverse Flow of Gas: Flashback Safety

[@redpost2380]

You can never view too many safety videos. Each one teaches something new.

[@ravanabrahmarakshas4263]

i knew about the flashback arrester, but reverse flow valve is new information. now i have to find this type of valve to add to my torch. thanks.

[@dido1803]

Great presentation,!!!

[@aliqadri4672]

When we shut off the torch a pop sound come.. What type of pop sound is that..??

[@ValMartinIreland]

It is amazing in this day and age that they cannot make a single unit which will stop flashback and reverse flow.

[@redpost2380]

Most FBAs on sale for a couple of decades have both. Don;t buy chinese FBAs

[@Boris_Chang]

Don’t buy any safety devices, potentially hazardous items, or edibles from them.

[@DerHund57]

@805Blink The way I've always learned is to quickly turn off the torch after the whistling is heard and then do the regular shut down procedure. I may be mistaken but that's how I remember.

[@formidablefriend8228]

QUESTION: I know it would be unsafe to do so, and there would be no reason to do so, but what would happen if you were to crack open an acetylene canister and light the air coming directly out of the canister? Would it instantly blow up the entire canister or would it just ignite the pressurize acetylene coming out and create a flame (somewhat similar to a torch before you turn on the oxygen)?

[@TheExplosiveGuy]

If for some reason you did this (dont do this) it wouldn't be too much of an issue, since there's no oxygen in the tank and the acetylene itself is stored in a porous material soaked in acetone there's really no way for it to burn into the tank.

[@formidablefriend8228]

@@TheExplosiveGuy Thank you. I am asking for a scene that I was writing in a book. It was hard to get a direct answer, but I've gotten enough answers similar to yours that the scene should make sense.

[@saginaw60]

Some say light torch with only Acetylene first (stink) and open Oxy after for safety.

"Can cause equipment damage and personal injury" Do we really need a poem for the word BOOM

[@rajsaroj9674]

Check valve doesn't stop flash back it only cuts the reverse flow,that's y flash back arrestors are compulsory.tnx

[@jabbarkhokhar6519]

is there any flashback for LPG cylinder.?

[@ravanabrahmarakshas4263]

i think you can buy an acetylene flashback and connect before the lpg regulator. here i see they use acetylene version. but do more research. www.aliexpress.com/item/32864954407.html?src=google&albch=shopping&acnt=494-037-6276&isdl=y&slnk=&plac=&mtctp=&albbt=Gploogle_7_shopping&aff_atform=google&aff_short_key=UneMJZVf&&albagn=888888&albcp=9444695485&albag=99457316601&trgt=296904914040&crea=en32864954407&netw=u&device=c&albpg=296904914040&albpd=en32864954407&gclid=EAIaIQobChMIjIzZ8Jvm6wIVFR4rCh3jKgMMEAQYAyABEgJsUPD_BwE&gclsrc=aw.ds

[@arthurn9237]

IT DOES NOT MATTER WHICH FUEL YOU ARE USING AS LONG AS YOU HAVE THE VALVE IN PLACE

[@RitikYadav-vl4dd]

thank u.

[@1873Winchester]

Can you connect a regular check valve and flashback arrestor serially after each other on a torch that doesn't have it built in?

[@ravanabrahmarakshas4263]

yes, that is what you must do

[@ajmalibrahim8115]

thanks a lot..

[@mycommentskeepgettingdelet184]

I love y'all

[@hahahaai]

yup thats true ,, just cut off the Acetylene as fast as possible and open oxygen valve

[@dthomp06]

Do I need this with an acetylene/air system.

[@Wat-Dat]

Yes. That's what he's using.

[@jibblesq]

Any torch or tank you use now has one built in. This video is way out of date.

[@ravanabrahmarakshas4263]

@@jibblesq do not be sure about it. there are tons of low cost torch in the market that they do not have it

[@shawndubay4050]

Would definitely highly recommend advise keeping flashback arrestors on both acetylene and oxygen connections of your torches. You don't want to be on the bad side of acetylene and oxygen. It could tu a very explosive and deadly mistake to go without good quality flashback arrestors. As a welder and cutter I will not touch a torch or even be remotely close to it unless they are equipped with flashback arrestors. No big boom 💥 for me. I have them on my cutting torch and brazing/welding torch and I believe my propane torch has one built in from the factory. I don't play with safety. Be safe and live a longer life.

[@Samartrader]

Now there is arrester which help ....For gas not come back

[@DerHund57]

@805Bink That was the wrong name.

[@bilginomi]

very good
