Taking that argument at face value, where does that leave a vesel with an
air horn?
In the event of a power failure the compressor will not produce high
pressure air and thus the horn cannot sound.
What doe the rules say about a manual non powered air horn ( whistle)
Don't recall ever seeing one big enough to be useful.
