I know its been asked before but bugger me if I can find it

Is it ok to drive with the gas on ?... I say yes he says no :hammer:
 
To be honest I Am NOT a big gas user & My Bottle is always OFF until I want to use it, However I must say I ‘Use’ to leave it on, & I actually forgot about it.
So I guess the sensible answer would be-
Best practice would be to turn it OFF in transit.
 
Surely the reason to turn the gas off when on the move is that if you are in an accident and the gas hose ruptures (the cylinder is very robust) then the emergency services SHOULD be able to assume that there will not be a gas leak to add to their problems, and their safety, if there is a fire.
 
Go & have a look at the -
‘Well That’s odd’
Thread, Then go back a cpl of pages to My Gas Locker,,,
Then imagine if I was on the M25 when it all went pear shaped with an OPEN bottle !
Brrrrr Shiver !

Well Thats Odd !

Another one for off.
Although that doesn't mean I always remember.
 
If you have gas it Four Hole refillable bottles then it is fine t drive with them on. They have many safety features built in including shutting off if you have a bump.
Any other bottles, and Big P is right!

Yeah, That’s what I got a ‘Gasit Plus’ 22 lt bottle, Supposedly Very Safe aren’t they.

I still turn it off though lol lol
 
If you are asking is it ok to use the gas ( ie boiler) when driving then the answer is No. If you mean driving with the bottle valve open then I suppose it would be ok but if you're not using the gas then there's no need to have it turned on!
In the event of an accident, gas hose rupture is a real possibility but in the event of a fire then the simple fact is that the very presence of a gas bottle would be a big hazard for the emergency services, ruptured hose or not, in a fire the bottle is a potential bomb. Hence the LPG sticker on your gas cabinet door (thats assuming there is one present) !

My previous 2013 Motorhome had the Truma combi boiler and the manual stated it could be used whilst on the move. As I recall there was some type of safety cut of valve that was incorporated into the gas system.
FAQ: Operate Truma heaters while driving
 
My MH manual has a note about using the gas convector type heater when moving, so gas would need to be on. Even without this note I do not turn gas off when moving.
 
We hardly ever turn ours off, think last time was just before getting on the ferry home from france last year,
 
We've got an underslung tank with a crash-sensor regulator, so leave that on when driving (I double checked this was okay with my insurers too). But, I tend to have all the domestic-side valves closed.
 
Plenty of propane-powered vehicles and their system is essentially the same as my fixed tank - except that being liquid draw-off in the propane powered vehicle, I guess the hazards could be even more serious.
Anyone heard of a propane bottle in an RV causing problems in an accident.? I watched a 40' RV burn to the ground in the USA (the fire started in one of the front wheels) and when it got to the big fixed tank there was no obvious change in the intensity of the fire.
 
When people are talking about safety devices ( not underslung tanks) a lot of regulators not all have an UPSO (under pressure shut off) so if pressure drops down stream the regulator locks closed preventing the flow of gas. Many a time people change bottles and forget ( myself included) and forget to reset it ,,,,,UPSO's trigger thinking there is a leak when changing a bottle typically to reset it is a simple case of depressing a nipple

With bottle top regulators they work great but one consideration is on bulkhead mounted regulators if it shuts down there is still gas in the pig tails being fed by the bottle , And it should be remembered that this is high pressure side of the system so instead of 30 mbar the pressure low side which the UPSO stops the pressure in the pig tails closer to is closer to 7 bar on propane or 100 psi in old money and this is why the gas should be turned off at the bottle

There are lot of vari8ations in setups so different answers but if you are in doubt close off at the bottle

Not to forget that driving with the gas on, is a different proposition to gas on and
driving with an appliance operational, in a m/home most likely the fridge of course.
Which contains essentially a naked flame, advisable to turn off before turning
into a fuel station, and possibly illegal to not do so.

InB4 someone asks how many people have been fried in a garage inferno,
due to this particular oversight, I've no idea !

I am not convinced there is a risk to others by leaving gas turned on, the main risk with lpg is if the tank is in a fire not leaking gas. Yes if the gas leaks inside the mh/van there is a risk of explosion but I haven't lost my sense of smell yet, just hearing, hair, teeth and a few other bits and pieces.

If a tank is in a fire it can cause considerable damage so dont know how an rv could burn and no noticeable difference be seen when the gas tank went.

A few yeas ago there was a fire in a campsite in France and a load of people were killed when the gas bottles went up, caravans and building were levelled and it looked like the aftermath of a fair size air exploded bomb had gone off if anyone remembers it.

Edit: If you are bored one day and want to liven things up, get a cylinder with some gas in it and a sledge hammer. Make sure you are standing behind the cylinder and hit the valve, you will see what a cylinder can do WITHOUT a fire. We occasionally di this in the quarry with big propane cylinders, very stupid but we didn't used to worry about things so much back then and H&S was something we said we did then ignored

I always turn it off. We have the Truma crash sensor, but why trust technology when it takes 8 seconds to turn it off. And as Channa said, the pigtails are highly pressurised.

Is it likely to be an issue? No, probability is very small. If it were to happen would the impact be severe? Yes, potentially.

When I used to do risk management stuff I'd then ask 'how much does it cost to eliminate the risk?' As mentioned, 8 seconds of my time per journey....

But, hey, that's just my view
