In WW1 the Royal Navy had a bad habit of leaving the doors open between the magazines and the turrets so that ammunition could be moved faster. This was in violation of their own safety standards and due to this the Brits recklessly lost a lot of ships at Jutland.
I recall reading that same practice being considered as a reason for the demise of Hood.
The US and Japanese navies in that same time required all the doors between turrets and magazines to be closed immediately before and after ammunition passed through them and that practice saved lives in both navies.
This was a common practice in the Battle Cruiser forces of the Royal Navy. A very strong emphasis on rapid fire above all else. Examinations of the battle cruiser wrecks at the Battle of Jutland showed numerous instances of safety doors in the powder hoists wired open, empty powder canisters where there they should not have been, etc. This was not the case in the Battleship forces. Their practice was deliberate aimed fire over speed. They strictly enforced the safe handling of powders and projos, requiring all safety procedures to be followed.
