You know those Dutch nutters?

The ones with the calcium carbide milk churns?

Here's what happened to a New Zealand plumber's van that had a leaky
acetylene bottle in the back of it...

Superb.

 

2009 pic, you can see his unexploded van on his drive.

Well obviously, you'd want to fill it partly with acetylene and partly
with air / O2 really....

Tee hee.
Me and my brother used to fill inner tubes with acetylene and throw them
on bonfires

If it hadn't amounted to a firearms offence we would have made a mortar
from some 3" tube and a sparkplug powered by a smidgin of petrol as
well......

 

Using the patented Mavis Beacon "Hunt&Peck" Technique, Catman

And you'd want to make sure that the bag was wet to reduce the chances
of a static spark making life a little too exciting.

 

Yes indeed.

In fact it would be safer to no recommend filling said bag with
Hydrogen, Chlorine and a flash gun.

Or a **** off big commercial bin bag, especially when you tie it off with
masking tape 4 ft long with the first 2 ft soaked in thinners. And for fucks
sake, NO matches.

Absolutely no connection, The quantities of acetylene are not remotely
similar.

 

Reminds me of this-

Scroll down to bottom.

One of the images.

In this case there was no fire/chemical explosion it
seems, just the energy of the escaping N2O when the
bottle burst.

Who mentioned quantities?
And who the **** are you?

 

OTOH, it's perfectly safe, on the midnight shift, to fill a hot
metal vessel with acetylene and then fire subatomic particles into it
through a very thin plastic window. It was my colleagues experiment,
but when he came to this part he always found other things to finish off
first[1]. Eventually, I was on midnight shift...

Acetylene also decomposes exothermically (releases energy as heat)
above about 15 psi, so pressurised cylinders are filled with acetone and
an absorber to prevent this happening. Always use and store acetylene
cylinders upright!

[1] He was worried that the ionisation from the muons might catalyse an
exothermic polymerisation.

Does the orientation of the cylinder affect the internal pressure?

ISTR the filler is steel (iron?) wool innit?

Do not know, you are the one who associated dutch nutters with a large
devastating explosion.

 

No, but it affects whether the acetone solvent stays within the
cylinder to do its job of supressing decomposition.

It's possible, but I've not seen mention of it. A prime requirement
is not to have any large voids where a pocket of gas could form, Perhaaps
you are thinking of some fuel tanks which are filled with something similar
to steel wool whose job is to suppress ignition of vapours by conducting
heat away before a chain reaction could develop (similar to the principle
of the Davy Lamp).

Cylinders are packed with a "porous mass" - see
http://www.hse.gov.uk/pubns/indg327.pdf

Note that it's been a couple of years since "under the arches"
garage/workshops were allowed to have OxyAce on-site, due to the distruction
to the rail service if a cylinder goes unstable.

I know of one mechanic that was given a MIG set as compensation from his
landlord.

 

It was a very long time ago that I thought I was told they were filled
with metal wool. I could be completely wrong. Ta.

Either I was mis-informed, or I mis-remember. Either is possible
