Fortunately my camp stove is a lightweight thing with 3 foldable legs and the canister is attached to the burner via a 75 cm metal hose , so there shouldn't be too much risk of it over heating especially as any cooking I do will be boiling water for pot noodles.
However, the thing is made n China so anything could happen.

Go full commando and use one of these like the native american's used to use mate.

This Fire Maple stove is made in China and gets a pretty good writeup. I dont think you will have any problem, the cylinder is well away from the flame.horace wrote:Fortunately my camp stove is a lightweight thing with 3 foldable legs and the canister is attached to the burner via a 75 cm metal hose , so there shouldn't be too much risk of it over heating especially as any cooking I do will be boiling water for pot noodles.

The fire maple FMS105 worked like a charm during the few days in Taman Negara.There were a lot of outdoor gear being used and tested on this trip. The Hennessy Hammock and the Fire Maple stove really lived up to their reputation. For now, the Hennessy will be my constant hammock shelter system for the jungle while the Fire Maple stove will be my go to stove for short trips.http://www.my-rainforest-adventures.com ... -the-test/

But it was the burner, and that one got banned. Beside that i can only read about accidents when the wrong type of gas is used. But ive not heard anything about that beein the case here in Cambodia. But even here the saftey-valve should take care of that as its the higher pressure that caused the accidents. So the gas should have been shut of by the burner.
And this thread on TOF Gas Canister at Cam's Burrito Cart on Street 172 Explodes, Injuring the Owner (Lisha)
Heres a quote from TOF re gas canister safetyKuroneko wrote:Duncan wrote:Investigations show that the most problems are caused by a overlarge cooking container placed on top, which spreads the gas flame outwards , and over the top of the gas container fuel supply.
Well, what confuses me is that what cause the explosion by using a oversized cooking-pan is that it heats the canister thus increasing the pressure.
So why dont the saftey-valve shut of the gas?
So i guess either fake stoves without working saftey-valve or canisters so old and rusty that they cannot handle the pressure anymore and exploding before the gas is shut of.
Edit: Or at least i thought it was standard to have that function. Isnt it? I have it on my stove.
There's exploding and bursting.
For it to *explode you'd need an ignition source (like the flane on the stove) and if the one in that women's bag exploded there must have been a naked flame in her bag!
*I know some fuels use pressure to ignite. Diesel for one.

pew, pew, pew, pew!
Many of the so called shut off valves are not always effective, and this led the Australian Govt to ban many of the stoves and put some legislation in place ensuring that the safety valves conform to Australian standard. So many of the stoves bought here are "spurious" However even if the valve works and you are using the superior CRV equipped cylinders explosions can still occur if the cartridge is incorrectly seated in the stove.Albro wrote:

Story of exploding stove below investigated by Chemaxx
The aerosol type butane canister was equipped with rim vent release (RVR) devices and the evidence indicated that the canister dome had expanded and the RVRs did in fact activate. It was experimentally determined that the dome expands and the RVRs activate at a pressure of 200 psig, which corresponds to a temperature of 200-225°F. In spite of the RVRs activating, the dome and body of the canister did separate.
When the incident stove was examined (with all parties present) it was determined that the main control knob on the front of the stove was in the OFF position. It was also determined that the safety shut off valve (SOV) had activated. The SOV is designed to turn off the flow of gas to the burner in the event that the butane pressure reaches 70-80 psig.
The finding that the SOV had activated begged the question: How did the canister reach the 200 psig needed to expand the dome and activate the RVRs if the SOV activated and shut off the gas (and hence the burner flame) at a pressure of 70-80 psig? Even after the trauma of the fire and explosion, the SOV and the main control valve on the evidence stove were tested and found to be functioning reasonably well. All parties agreed that the butane canister did not show any manufacturing, mechanical or metallurgical defects that could account for the explosion. Tests on exemplar canisters showed that the canister would withstand exceptionally high pressures without bursting.
Why it exploded
The plaintiff's theory was that the design of the canister and stove allowed the canister to be inserted incorrectly by ¼ turn such that the exit tube inside the canister was pointing toward the burner instead of the sky. It was hypothesized that this resulted in "erratic burning" which in turn heated the canister and caused it to explode. This made sense on a qualitative level because the ¼ turn configuration would eliminate the "evaporative cooling," at least for a while. However, when this hypothesis was experimentally tested, the heating phase only lasted until the liquid level fell below the internal exit tube, at which point evaporative cooling returned. This is demonstrated in the animation below that uses actual experimental data.

Great road from Phan Rang (near Nha Trang) to Dalat. Snakes up and gets windy and windy, so yes, occasional landslides a problem, especially when wet. I'd suggest a heavy coat, strong head light, and good tires for the rain. Speed not a problem when going up. The clouds (and damp chill) make it surprisingly cold up there.horace wrote:Cheers for the advice on the canisters. As for the road from Nha Trang to Dalat I was advised by some local cycle guys not to as the rains had washed a lot of it away. The weather here has really been terrible,apparently the worst wet season ever, been stuck in a Quy Nhon for a week now because of the rain and no end in sight.
Takes the guys a day or two (depending on weather) to clear the road. The locals are hospitable enough, if you don't mind shacks and oil lanterns. Cash is king, but if they've only got noodles and eggs, that's it in the mountains!
Beautiful views, when clear.
There's an abandoned rail line along thst road. Hiked a bit, even has semi-spooky train tunnels you could possibly shelter in.
There's also a dam about halfway up the road to Dalat.
