Hi, I really enjoy the information and thoughtful discussions here. This is quite a community -- I've been reading through past threads for about a month now and have have learned a lot.

I am putting together a kit for my SUV (no trunk). I would like to keep some 8oz. isobutate/propane canisters along with my MSR stove there, but am concerned about the safety aspects.

My question is:
With temperatures in the 90's here in the midwest this week (with inside the car temps probably over 120 F -- as high as my $2 thermometer would register) can anyone help assess the danger/risk of storing these in a backpack in the vehicle? The last thing I want is to injure myself, my vehicle, or others (and also not wanting to look like an idiot should something unfortunate happen) if this practice would not be safe.

(I haven't contacted the manufacturers yet, as I assume from a liability standpoint they would just provide a blanket 'Don't do it', without any guidelines)

Also, any info/experience on safe storage of any other fuels (regular propane, white gas, etc.) if the isobutane/propane is not a good idea would be helpful.

Your thoughts are appreciated. <img src="/images/graemlins/smile.gif" alt="" />

No idea about the fuel storage, but I've placed one of these in my car in July in Florida. Highest recorded temp was over 150F. Didn't take long to get to that temp either.

It's interesting to compare the design of a solar oven to a typical car. <img src="/images/graemlins/shocked.gif" alt="" />

Of course, the temperature sensor was placed in the cabin area. I don't have a trunk, so I have no idea how much less the temp is there.

Edit: One thing I keep meaning to do is put the sensor in a styrofoam cooler. I would imagine the cooler would decrease the maxium temp some, and slow the temp rise but I can't even guess how much. I was thinking about this for long term food / water storage in the car, but it would apply to fuel containers, too, I'd think.

I have not irst hand experince, but I'm going to take a big stab in the dark and say it is probably safe, for one reason.

Have you ever worked on a loading dock? I've been in trailers that had been in the sun all day when it is a hudred degrees out. And this stuff is carried on trucks, so to be safely shippable, it should be able to deal with the heat.

But I'm just guessing. Your stove's manufacturer would be able to say for sure.

Hi Buckeye,

I've kept 225gram primus iso/pro canisters in my car for years. Never had a problem. I think you'll be fine in Ohio. All disclaimers apply though.

BTW I'm not sure if my profile says so, but I'm in a hot part of FLA (redundant eh?).

I don't know the answer to the original question, but "... this stuff is carried on trucks, so to be safely shippable, it should be able to deal with the heat" made me think.

First, it probably takes more than available daylight hours to heat up a mass of stuff that large. And they usually seem to carry it in white or chrome tanks, which would reflect sunlight.

I wonder if anyone has ever done a temp check to compare the inside of the same model of car, side by side, to see if a white one stays cooler than a black one? Unless the windows would negate any difference...

Yep -- did that once. Black vs. white lexus sc400 coupes. 12 degree difference on a sunny, 97 degree July Texas day. Both cars in the sun all day. Peak temp was 137 vs. 149 at a little after 3pm. Ouch.

Thanks for all the info and thoughts. I think I'll try carrying one small jetboil can. BTW, I love my jetboil. it gets used more than anything else when we go tent camping.

Thanks again!

Michael
