Gas safety

[sarabande]

It's all in hand, as it were. With an expedition due to sally forth into the gas locker next time, and then to assemble all the primary owner's gas wands and ciggie lighters, ether starter cans, paraffin, engine oils, two stroke mix, petrol, paint, greases, rope gas torches, gas soldiering irons, romantic candles, wethylated spirits, furniture polishes, foam makers, fly sprays, silicone sprays, and any other vaguely inflammable hydrocarbons into one single, frighteningly explosive locker.

Or should I distribute the risk around the boat again ?

Anyone know the rate at which copper pipe work hardens please ?

"Gas lockers open at the top to any confined space are not worth the name."

umm, if leaked cooking gas needs to escape it will do so downwards through the purpose built hole in the hull. If you seal up the locker lid you could be making a bomb by confining the gas/air mixture. Gas lockers should be outside the internal habitable structure of the boat.

See the Trenchard MCA report.

I would go further and say the gas locker should be outside any internal structure of the boat.

Suggests other people think differently....
I've read the Trenchard report (ages ago), I suspect the MCA may have missed the point again.

Why would gas squeeze through a small drain hole when there is a big open space for it to expand into? Actually, some or even much of it may, because it comes out very cold, hence very dense. But plenty of it will go upwards too.

At the end of the day, a locker is only a second line of defence, it is no substitute for connecting the bottle properly

Which after all was the prime cause of the Trenchard explosion, as well as the badly constructed gas locker and the gas detector sensor being in the wrong place.

Weths. Our bottle comes from Oztralia.

Perhaps the insurance companies could extend the requirement for a BSC and not supply an insurance document without a safety cert. After all you cannot get an inland waterways licence without the BSC. On a voluntary basis owners could check their own boat against the BSS reccomendations. If you don't then don't be too surprised if you have a problem. The BSS covers more than gas of course and is an excellent starting point for a safety check, even if you don't actually have to do it on the briney

Is all of the BSS appropriate to a seagoing boat? I've heard that it can end up insisting on ventilation requirements that would flood anything which had to go to sea.
