A problem with multi-gas detectors is that the best location for a detector
depends on the gas.  E.g., propane is heavy so the propane detector needs
to be on the floor, but you want the CO detector at eye-level.

You can get propane detectors that come with a valve you install on your
external tank to actually shutoff the propane supply in case of a leak.  We
have one of these installed, here's a photo:

With the switch in the off position, the alarm is off and propane is
shutoff at the tank.  When the switch is in the on position, the external
valve opens and the alarm arms.  If it detects propane the valve closes and
the alarm sounds.
