Transporting oxy-acetylene
I need to move my oxy-acetylene bottles a short distance about 1 km as i’m moving. I only have a sedan to move it so am thinking of putting it in the boot, have read of safety concerns but opinions divided about how the safety of lying bottles down and the potential risks involved. Any thoughts?

1km only? Put them on a cart and walk them.

I transported O/A a fair bit and yes they can be laid down but the Acetylene must not be used for a few hours to let the liquid settle to the bottom of the bottle before using it. I am sure the transport regs say they can't be transported in a car also.

Hi Tiger,
As mentioned above. Not in a car. Not legally!
Got a mate with an open back ute?
Below is some guidance about the regs.

This is what a vehicular acetylene gas explosion can do:

Nope. Nope. Nope.
Flammable DG class 2.1 like acetylene are not to be transported in an enclosed vehicle.
They (acetylene) need to be transported upright. They are liquid filled (acetylene and acetone dissolved in a porus mass within the cylinder), so laying it down would render the cylinder safety devices (relief valve or fusible plug) ineffective.
Any regulators need to be removed prior to transport too.
The details are in the DG legislation, a good guide is provided by ANZIGA (Aus/NZ industrial gas association). Some things are different for commercial transport vs 'own use' but this mainly relates to records (DG manifest etc).
Australia New Zealand Industrial Gas Association is one of the regulatory bodies with some useful info.
About carrying in vehicles (refer to the DG class 2.1 stuff for acetylene, 2.2/5.1 for oxygen).

The law says you should not speed either.
Before we say the law is the law, ask yourself why it is written that way. To me it is the same as the old one rule for absolutely situation because that is very easy to do and who cares who it inconveniences as the ones making the law will most likely never be encumbered by it.
So the person transporting it 100m is considered the same as the person transporting it 100 000km.
Does anyone think the rule was made because of leakage issues. If it was transported in an enclosed area and leaked, when you open the boot there is a chance an explosion could ensue from an ignition source, like the boot light switch arcing.
If it was adequately contained so the tap can not be knocked, no leakage with a bubble test, well..... You still can not do it.Gold, the colour of choice for the discerning person.

Interestingly the BOC guidelines state.
Use open vehicles or trailers in preference to any enclosed vehicles or trailers.
Anyway I'm surprised no one has mentioned a trailer. You just need one with a sturdy tallish cage.
And picking up on RCs point, here are some other significant factors to consider that could mitigate risk.
Drive at the quietest time of day on road - that's usually very early morning around our way.
Drive slowly - KE=1/2mv^2
And has already been mentioned, drive with boot propped open.

reasons why they tell you how to transport them.
They dont want the valves to be broken off or you'll have a rocket on you hands..especially oxy, and for acet a bomb!
stand and chained vertically and in open vehicle...
having said that there are plenty of tradies with cylinders in vans and some not fastened in vertical position...been a one or two vehicle explosions as well...
so the risk is real but slight...... if nothing goes wrong

Is it just the acetylene that is an issue?
BOC had no issues with me transporting an oxygen cylinder in the boot, this was about 20 years back.
But what happens in an accident? Probably not the best idea.

Back in the good old days when my daily earner was strucual steel onsite fabrication i made made a
rule that there was no smoking in the van until driving 1 klm with the window down.
Another rule i had was to ensure the valves on the gas bottles were off.
cheers, shed

back in the 90s, I used to collect the bottles from BOC for my dad panels shop, we just put them in the panel van to drive back not issue and no one cared.

The main risk of explosion in an enclosed space is a slow undetected leak over a long period of time. Putting a cylinder in your car and immediately driving 1km will have virtually nil risk of explosion from any leak. Theres just not enough time to build up a flammable mix, even though acetylene has a very broad flammable limit making it one of the most dangerous gases. Up there with hydrogen.
I can't comment on the risks of laying them down for the 5 mins the trip would take as I'm rather ignorant of that part.
When I go camping I try to always carry our lpg bottle external, usually on the roof rack. This is for the same reason as above. Having said that, I'm happy to put them in the car for the short time it takes when I get them filled.

I have transported oxy And acetylene hundreds of times laying down with no issue in the boot BOC don't seem to have any concern, well as of last week any way, loaded the acetylene in to the boot for me.
as said above you don't use the acetylene laying down or it will draw off liquid instead of gas, just stand it up for 15mins before use.
I am not telling or suggesting for anyone to go against any regulations or laws I am only laying out my experience
