It's probably worthwhile to explain why
propane and CO detectors are a good idea.
Most of our trailers (some have converted to all-electric systems) have various propane-powered appliances. Our trailer has one gas line that enters at the front of the trailer and wraps almost all the way around the inside of the trailer at floor level. Along the way it has gas lines that "T" off and connect to the furnace
, the stove top, water heater, and refrigerator
Each one of those "T" connectors is subject to the same vibration and flexing as the rest of the trailer, so there's a small but not insignificant chance one of those T connections will develop a leak someday. My trailer electrical
wiring is subject to the same kinds of potential problems, but has fuses that protect the trailer from developing a short that could start a fire. The propane system does not have a fuse . . . it's safety mechanisms are it's "gas" smell (which comes from a chemical additive) and a propane detector. Since propane gas hangs out at floor level, well below the level of your nose, you might miss the smell if you're asleep. If that ever happens that propane detector, like your electrical
fuses, can make the difference between detecting a dangerous situation before any damage is done, allowing you to spend another several years enjoying your trailer, not spending those same years recovering from third degree burns. Or worse.
A CO detector's job is the same kind of thing. Carbon monoxide is odorless, colorless, tasteless, and lethal. It is made almost anytime you have flames burning propane. Trailer furnaces, water heaters, refrigerators, etc. vent those combustion byproducts outside the trailer. Repeated heating and cooling can, however, crack the exhaust manifolds and allow CO to escape
into and fill the trailer. If that happens you go to sleep . . . and never wake up. The CO detector is the "fuse," the safety device that prevents that from happening.
Hopefully none of these things will ever happen to you or your trailer, but isn't it worth spending $100 so you don't have to worry about your life . . . or the lives of your partner, kids, grand-kids?
