Propane safety

Hello all. So I have searched this and other sites regarding traveling with our refrigerators running on propane. I have done this when traveling several hour trips in hot weather and it seems most others do the same. I have read that the newer valves on the propane tanks will cut flow of propane should there be a catastrophic failure of the gas line due to a cut/break or accident. My concern would be if a fitting loosened enough from vibration or whatnot and caused a slow leak in the trailer causing KABOOM while going down the road. Haven't found any posts that takes a slow internal leak under consideration. Is this a valid concern or do I just need something else to worry I know its personal choice to run refer while on the road as they are designed to, and will continue to do so, but curious what your thoughts are. Regards, Jim

We travel with fridge in operation all the time. What could be of a bigger concern is the chance of gas vapors lingering back to the gas flame on the fridge, if you stop to top up the tow vehicle gas tank. In my case that is considered slim to a near nil possibility considering the fridge is on opposite side of the vehicle tank fill and about 25 feet back. I also have little to zero concern in a propane gas build up causing an explosion while traveling. But at the same token one should never say never, but I wouldn't loose any sleep over it...

You are worrying about something that is preventable. Ensure things are tight, etc. and have fun. Don't over think it.

Not to mention the screaming siren that goes off if you're leaking propane into the cabin area.

Trust me, I know......

(Mine wasn't leaking just a defective sensor in the gizmo.)

Propane concern

If you are concerned about a small leak while travelling, why not leave a couple of windows slightly opened? Would this help?

100% of manuals will tell you to shut off propane for travel and 98% of people including service techs travel with propane on and their fridge running.
By law the only concerns you may have are highway tunnels where there are postings for propane and at fuel stops.

Not an expert here but I run with my propane on to keep the refrigerator running. As someone said if you go into a long tunnel, such as the one at Norfolk, VA you will have to stop so they can verify it is turned off. And, if my memory serves me right you can only have the small (5 gallon) size. Oops, and I've changed mine to the 7 1/2 gallon size.

I run the twin 30 lbs. and they inspected at the VA tunnel bridge. No problem have the 30 lbs tanks.

As far as turning off the lp, I wonder how the lp powered cars, trucks, fork lifts have no problems running on lp.

From an article on propane safety.

There is a black thermal-sensitive bushing found just behind the green nut. If this bushing is ever in a fire with temperatures between 240°F and 300°F, it melts and allows the brass nipple inside the nut to move back about ¼ inch, which closes a small piston inside the cylinder valve totally shutting off the flow of propane. This innovative feature will help prevent fires or explosions. The second new safety feature is called a “flow-limiting-device.” Its purpose is to restrict the flow of escaping gas if there is an excessive leak in the RV propane system. This second “flow-limiting-device” feature and how it works forms the core of the secret! Almost every time the cylinder valve is opened, a small ball in the center of the brass nipple (inside the green nut) is pushed forward into a brass seat.

Mark, those vehicles aren't manufactured by the RV industry.
