Welder Sparks Off Gas Tank Explosion
Cambodia News (Phnom Penh): At 3:50 pm on October 5, 2022, at the 24Hour HANA Gas Tank Dealer Shop on St. 271, Sangkat Phsar Deum Thkov, Khan Chamkar Maun, Phnom Penh, a welder suffered severe burns following a gas tank explosion while welding.
According to the source, the victim was hired by the owner to work at the shop, when the sparks from the welding met the nearby gas tanks causing them to explode. The explosion left the victim with some serious burns and he was later admitted to the nearby hospital, but his days are not in danger.
Fortunately, the explosion was not more serious because it occurred in a populated area with many people coming and going. The police blame the accident on the welder for being careless.

I blame the owner for allowing welding near gas bottles. Occupier's liability will put the blame on him and anything his workers do in the course of their approved work practices also places the blame on the business owner under vicarious liability.
But hey, this is Cambodia, so blame the little guy for doing his job and let the boss off the hook. He probably won't even have to pay for his medical care for his serious burns.

Re: Welder Sparks Off Gas Tank Explosion
I’m not sure the police are best suited to determine cause, blame or responsibility. It doesn’t seem like exhaustive investigations are carried out too often, and they shouldn’t be apportioning blame.
Gas bottles are pretty damned robust. Sparks being near the bottles is nothing. Sparks near dodgy regulators, damaged hoses, loose fittings is quite possible. Bad practice may be involved, but the actual cause I’m sure has not been established.

Re: Welder Sparks Off Gas Tank Explosion
When propane (or any flammable gas) cylinders/tanks are in decent condition, sparks from welding or grinding are not particularly dangerous (unless you weld directly to a steel bottle).
Most gas explosions are caused by gas leaking from containers that are damaged, have not been shut off correctly, or are leaking gas from damaged hoses/fittings.
The red gas cylinder shown in the photo, is fitted with the hose and connector used for transferring gas from a larger cylinder to a smaller one (basically, for filling several smaller cylinders from a single larger one)
I’d bet that there was gas leaking at the time, or escaped gas accumulated in some space or container, which ignited when the guy started welding.
Contrary to popular belief, gas cylinders rarely explode, even when heated, say in a burning building. They are fitted with pressure relief valves, which vent when a certain pressure is exceeded (for example if the cylinder is placed on a fire, causing the contents to heat and expand) Rather than rupturing and releasing the entire contents, the gas is vented in a steady stream, which ignites and burns off (in a similar fashion to the spray from an aerosol can being lit) in a controlled manner.

Re: Welder Sparks Off Gas Tank Explosion
I’m happy to stand corrected if it is a fire extinguisher, but it does resemble the rig I’ve seen used in some gas bottle shops for refilling cylinders.Bluenose wrote: ↑Fri Oct 07, 2022 7:14 pmScrub my upvote - I'm 99% sure that the red cylinder in the photo is actually a large capacity fire extinguisherChad Sexington wrote: ↑Fri Oct 07, 2022 11:56 am When propane (or any flammable gas) cylinders/tanks are in decent condition, sparks from welding or grinding are not particularly dangerous (unless you weld directly to a steel bottle).

I was speculating on that maybe being the source of leaked gas.
