LPG Safety Question

[Camp CA]

My power and sail boats have a manual solenoid switch to isolate LPG to the cook top/oven. The power boat even cycles for 60 second cycle to confirm no LPG leak by 2 detectors before it will allow opening the LPG solenoid valve. I once had cook top burner slightly open and it leaked LPG into the trailer, which eventually triggered the LPG detector alarm went off as I was outside the trailer and a neighbor alerted me. That event occurred on a blistering hot day when the rv park lost power and the motor homes on each side turned their generators on to power their AC's so I was really concerned the LPG leak could have caused an explosion and fire. After that event I make it a rule to manually close the LPG tank valves and disconnect the LPG hose to it after use. Curious why trailers do not have a manual solenoid switch to open and isolate LPG to the cook top /oven and furnace to safeguard a potential leak?

Because the manufacturers and the government don’t see a need.

That's the reason for the LP (gas) detector, and why they are separately wired to the RV house battery, and battery disconnects still don't shut the LP detectors off, and why there is always parasitic draw on your battery powering the LP detector. It's so the LP detector will warn when there is a gas leak or a gas appliance was not turned off correct or the flame is not burning correctly.

Your camper did EXACTLY what it was designed to do. It warned you before something tragic happened.

The reason for all those safety features on a boat when propane is present is because propane is heavier than air and will fall to the bottom of the boat and accumulate in the hull, which is the hazard. Natural gas, like that supplied to your home from a utility, is lighter than air. In an RV, typically the floor of the RV is the low point, but even with below floor storage, there isn’t an area that is sealed well enough to collect an accumulation of propane that will cause a problem like on a boat, so the simple propane detector is sufficient as a safety device. Also, I’m not sure what this has to do with the COVID thread.

Thread moved out of COVID.

We were discussing this the other day as our Class C had an LP shutoff switch. I'm assuming it had something to do with the inaccessibility of the fixed tank. I do know the solenoid uses lot of power to keep it open.
