I understand there are sniffers to detect propane build-up but if such a
pocket of collected gas is found how do you clean it out and make the boat
safe again?

Open the hatches and circulate air.

Propane isn't any worse than gasoline. Both are heavier than air and will
settle to the lowest spot. In most cases there will be a path to the lowest
part of the boat, which is generally the engine compartment where there
should be a bilge blower. Run the blower to get the fumes out.

IF yo have a propane locker it should have a drain leading directly
overboard so that any leaks there will take care of themselves.
