Do they have fire sprinklers on ships?
Back in the old days, they just covered everything with asbestos. Can’t do that now.
Some ships have fire suppression systems, yes. Every kitchen on a ship, even submarines, has some kind of fire suppression system over the grills and in the exhaust stacks.
Other than that, no sprinklers on a boat. That’s why we have watchstanders both underway and in port. Every accessible space is checked at least every hour, if not more. It’s their job to find a fire (if one exists), and sound the alarm as quickly as possible.
And, BTW, NO asbestos installed on ships anymore. There may be some on very old ships (carriers). Which is why when they install new insulation, it is first painted red, before it’s painted its’ finished coat. The read undercoat indicates that the contained insulation is NOT asbestos.
