Oh this is a whole new level of crazy/stupid conspiracy nonsense.
Fires on ships are hugely serious - and hugely dangerous - problems. There would have to have been multiple smoke sensors and heat sensors on every deck, including the vehicle deck, plus automatic fire suppression systems of varying kinds.
So..... if this (ridiculous) theory about mystery hazardous inflammable cargo suddenly lighting up had truly occurred (oh, and most events like this require an ignition source....), the bridge would have been awash with lights and alarms. And it's also very likely that an automated public announcement would have been broadcast to passengers over the PA system. Yet, of course, not one person recalls any of this actually having happened.
Seriously, how much more indication is required that these nutters - however well-meaning or "investigative" they might be - are manifestly unqualified/uneducated/ill-informed to be worth even listening to?
The fire alarm DID go off and an automatic coded message, 'Mr. Skylight 1' and 'Mr. Skylight 2' did go off. this was a code for the crew to know where their meeting point was to deal with passengers. It would explain the water spraying over the car deck monitors: fire sprays, not seawater.
