We must have a lot of OSHA inspectors here. I have worked in wood heated repair shops (montana) for years. The other thing for me is lower temps tend to make gas less volatile and our climate here tends to be a bit cooler than the hades like temps in the south. Right now we have 25 gallons of gas stored in five gallon plastic heavy duty gas cans in the shop which is heated by a wood stove and a pellet stove.
One shop I worked in had the wood stove up on legs since the rule was two feet above the floor since most vapors like propane and gas sink to the floor.
Gasoline is very detectable to the human nose and most people will smell it in very low concentrations, before it becomes a problem for explosions or fume poisonings .
A lot depends on how air tight your shop is I suppose, I usually have a gas can or two in my art welding shop but it is drafty and I store the large quantities outside in sealed 55 gallon barrels. There is a real danger in mixing combustibles just ask a rural firefighter why they don't like garage fires.

Good thread going here. Right now i am taking some time off work but normally I am busy working on motorcycle and four wheeler carbs. Us old guys know what's what without plugging in a engine analyzer to the fuel injection system. I regularly drain gas tanks and carbs and function test carbs when done rebuilding them. Sometimes you need

to do things to get the job done.
The only fires we seem to have around here are arson or obvious sloppy woodstoves or propane leaks from home made systems.
I love montana, few government inspectors and people are expected to know what they are doing.....and if you are stupid or careless you get the natural consequences. Kind of like self reliant survival in the hostile environment that is coming at you.

I have a similar question also. I'm hoping to build a garage with a house walled off inside it. If I can, the woodstove would be in the house, separated from the garage and gas. Would the stovePIPE going through the cieling of the house, through the open-air in the shop to passively heat that, then through the metal roof be bad?

Stove pipes and how to run them thru walls or roofs is proven science. Also the height above the roof and any high points of the roof.
It is also expensive to buy the really good double or triple wall pipe. i always try to run my stove pipe as close to vertical as possible. and thru any roofs or walls use the triple or double wall pipe.
The best wood stove i ever did was in a 30 foot dome with the wood stove in the center and a rock backdrop for the the stove and pipe. Black single wall pipe to the roof where i had double wall thru the roof. The wind could blow from any direction and the stove always drew well. Lots of heat, so much that I had to use a blower in the loft to blow some heat down into the bathroom.

yes don’t do that it is a bad idea .
Your flue need to stay hot so you done have Creosote form on the inside of the pipe .
Running side ways would allow your flue gas to cool and plug your pipe .

My buddies dad had a old farm house and he had a wood stove in the corner of the dining room after thanks giving dinner he would have us move he table and slide the old wood stove into the center of the room and hook up the black pipe to it.
The pipe ran thru the wall and down the 30 ‘ haul then up to the second floor thru all the bed rooms 6’ off the floor and back down the haul and up Thur the ceiling he cleaned out 10 gallons of creosote out of the pipes every 2weeks till Easter .

Wow, a 30 run of horizontal black pipe? Usually those kind of set ups result in a raging chimney fire with chunks of flaming crap spurting out and landing on the roof. Lots of people burn wood around me and straight up is the way. We also burn pine and fir in stoves.
Deathmaul your project sounds like you need to do some figuring out of thermal dynamics.
If you have a wood stove in a studio apartment size the stove so it doesn't roast you out, you need to burn the stove fairly hot so it doesn't create creosote in the stove pipe. If you want to heat the shop i would have two doors or a door and a openable window in the apt and open those to get some heat in the shop.
But a metal building will take a lot of heat if it really gets cold outside. Of course your cold isn't like montana cold when it gets down to -30. Keep your stovepipe straight and inspect and clean it as necessary. There is a lot of info on the internet written by people who burn wood to heat their places and I would listen to actual experience rather than gloom and doomers who haven't heated for six months out of the year.

55 gallon barrells with tight fitting screw in bungs. Summer heat makes the barrells bulge a bit but I can keep gas for two years. I shield and cover them a fair distance away from my buildings. $200 a barrell of gas now.......what would it be worth when the stations run out.
