Re: Propane leak into the bilge. What to do?
I don't think any electrical air handler would be safe in that circumstance. I might think about having a CO2 or Halon extinguisher to fill the bilge with a non-combustible gas. If the bilge was filled with a mixture of CO2/Halon and Propane, it SHOULD act to prevent any explosion to allow you to then turn on a blower.
