The Maritime Safety Committee, at its sixty-fifth session
(9 to 17 May 1995), agreed that the requirement in SOLAS regulation III/50, as amended by MSC.27(61),
for sound pressure levels complying with the standard developed by
the Organisation, and for the alarm to continue functioning after
it has been triggered until it is manually turned off or is temporarily
interrupted by a message on the public address system, should be interpreted
as to only apply to ships built after 1 October 1994. The requirement
that the general emergency alarm system be audible on all open decks
should be interpreted so as to only apply to passenger ships built
after 1 October 1994.
(Provisions for passenger ships carrying more than 36 passengers
built before 1 October 1994 are contained in SOLAS regulations II-2/41-1 and 41-2.)
