RE: [PSUBS-MAILIST] Battery Safety Issues

Brent,

With the batteries located inside the pressure hull without a proper sealed container, I would be more worried about the sulfuric acid and chlorine gas that will become an issue with flooding. With a rapid discharge of the batteries (or during charging), explosive hydrogen gas can also be an issue. A prudently designed, well tested, and properly maintained submersible shouldn’t be getting into the flooded situation anyway J.

Sealed breaker (fuses for high amp DC) boxes and conduit will minimize stray electrical issues in a flooding situation.

A skimmer afloat is but a submarine, so poorly built it will not plunge.

If you have one or more batteries in the pressure hull with you, and not in a sealed off area, how do you keep from being electrocuted, if the inner hull floods? Will not the batteries short out in fresh water, and even more so in saltwater? I would love to be enlightened. ; )' Perhaps someone else wants and/or needs to know as well.

Even if the batteries are in pods, or another hull section, will not the breaker box cause and other wire cause your trouble?
