Oxygen generators use electricity (electrolysis), not steam.

Thankfully, we never had to use oxygen candles. Candles are effective only in a small closed space. That would have been a serious emergency.

Ah yes, was referring to the excess drinking water aspect knowing electrolysis upon sea water will produce chlorine due to the salt, which really would be an emergency in itself.

Glad to hear you didn't have a situation to use one and does seem a very rare situation, but neat that there is a solid backup.
