There are many steps that need to be taken to ensure your safety when travelling in your RV. For example, it is very important to make sure that your RV is protected from propane gas leaks, as propane gas is very flammable. Because propane is heavier than air, it will settle toward the bottom if there is a leak inside of your RV. This is why the RV propane leak detectors are located on the interior flooring level, toward the bottom of the RV. In the past, RV propane leak detectors were very sensitive and could be set off by almost anything. Although RV propane leak detectors are much less sensitive today, they can still possibly be set off by other chemicals, odors, etc. They can also be set off if you have low house batteries. However, even if you suspect that the detector alarm was set off by something other than propane, it is important to exit the camper as soon as possible to ensure safety. If at any time your RV propane leak detector goes off, make sure to shut off the LP system at the valve on the tank, and all of the appliances. Lastly, make sure to have the unit tested before resuming with your usual travelling and activity.
