1 The Maritime Safety Committee, at its seventy-first
session (19 to 28 May 1999), approved Guidelines for the approval
of fixed water-based local application fire-fighting systems for use
in category A machinery spaces (MSC/Circ.913).
2 The Committee, at its eighty-eighth session
(24 November to 3 December 2010), having considered the proposal of
the Sub-Committee on Fire Protection, at its fifty-fourth session,
approved the Revised Guidelines for the approval of fixed water-based
local application fire-fighting systems for use in category A machinery
spaces, set out in the annex.
3 Member Governments are invited to apply the
annexed Revised Guidelines when approving fixed water-based local
application fire-fighting systems for use in category A machinery
spaces, and bring them to the attention of ship designers, shipowners,
equipment manufacturers, test laboratories and other parties concerned.
4 This circular supersedes MSC/Circ.913, except that fire and component tests previously conducted
in accordance with MSC/Circ.913 remain
valid for the approval of new systems. Existing fixed water-based
local application fire-fighting systems approved and installed based
on MSC/Circ.913 should be permitted
to remain in service as long as they are serviceable.
