Who travels with furnace on? (Truck campers)

Have any of you seen the Myth Busters episode where they were evaluating if using a cell phone at a gas pump posed any danger to igniting a fire? I found it very interesting, but don't want to spoil the fun for those that may want to watch it.

I just located this link:

However, it's an abbreviated version and leaves out the most fun parts of the episode. I believe you can stream Mythbusters from Netflix, or rent the dvd.

Check it out and let us know your thoughts.

Pressurized gasoline and DC batteries make trouble sometimes. Perhaps more than propane.

Thanks Matt and Old bisquit

In my opinion... having the propane tanks valved open is reasonable safe when traveling.

It is important to have the propane tanks and regulator situated outside the enclosed quarters of the living space to prevent a slow leak from building up an explosive concentration.

The fridge, furnace and hot water tank are all outside the enclosed living space and vented

It is important to have all of the piping and fittings possible outside the enclosed living space. Vibrations can induce slow leaks.

For the above reasons: The cook stove/oven, and heaters like the Wave and the Platcat are inside the living space and should not be left running unattended while traveling

I tried opening a propane bottle all the way to empty the cylinder... I couldn't get the propane out that way. The tanks before the ORP valves would empty so fast that they'd frost up.

I'm guessing here:

I think the real danger of explosion / fire is a slow leak that alows the propne to build up in a closed area... then a spark or flame

Be good to have an expert chime in.

There are a several safety features on cylinders.
The OPD (Overfill Protection Device) valve has a couple.
Shuts off filling of cylinder at 80% capacity and has a spring loaded shutoff valve that is closed when cylinder is disconnected OR if thermal bushing in pigtail connection should melt due to fire.

The pigtail connection (Acme Nut) has the thermal bushing AND a check valve (ball that moves) that will close if excess flow occurs due to line break etc. The 'ball' can close if propane cylinder is valved in too fast....it floats stationary in the middle due to equal pressure on both sides of ball. Open too fast and it moves to one side closing off because of high pressure on one side/low pressure on other side.

The ACME nuts (big green right hand thread) have been mandated since 1998
The OPD valves since 2001

Aye, you have to use a hand nut assembly that has nothing attached to keep the spring valve open to do that.

Run my furnace , fridge, and water heater for years no problem.

Traveled today with furnace on. No problems and toasty warm. Spark ignition type furnace.

Always, all across the country :). Like my rig not frozen :p.
