Blow torch safety

[dazplum]

Hi all, when you sense there is only a little gas left in your mapp or propane bottles, is it best to just let the gas burn off, or can this cause light back down the nozzle and cause the cylinder to explode?
Or do you just wait until the pressure is low and replace the cylinder?

many thanks

On a side note, my wife kept her horse at a local farm.

The farmer returned a month or so ago with a huge smile on his face and was pleased as punch as he told her about his afternoon.

"Oi've just been down to the fields today and pumped propane and oxygen into the mole runs. Then I put a match to it. You should have seen the explosions. Looks like the Sommes down there now!!!"

had an apprentice once wanted to strap 4 of them together to throw on a fire and see what happens........

He stayed in the van a lot.......

why didnt u let him try ?

They do seem to last a long time don't they. There's a lot of fire in such a little can.

Don't worry about them exploding when empty. When they're empty, there's no gas left in the can to explode. They just fizzle out!

 

[markfxy]

just use it till it runs out hows it gonna explode if its run out of gas??

its unlikely a flame will get near a bottles valve as there wont be enough oxgyen at this point.

You can get a tool to remove the fill/relief valve on the bottles so it can be disposed of as normal waste or given to the scrap man.

It's called an angle grinder isn't it ! ;-0 Lol
Dont try this at home kids!!!!

 

[Dannypipe]

I don't bother recycling mine, they just go in the skip when they're done!

Just a little side note.
there is gas left in the can unless you upen the vent on the bottom.

just not enough pressure to force it out with a torch.

when heated when"empty" the pressure goes up and you get a boom of a presurised cylinder + a flash fire fromthe remaining lpg

Maybe you should go on Mythbusters!!!!!

I live in a farm, the bottles get used as target practice first!

i had a new one which was leaking from the bottom vent.

that got thrown in the bonfire, only took a minute to go bang and they really do fly!

I still use a petrol one, when its empty it just splutters and stops, don't tend to refill it until its gone cold :93:
