Statutory Documents - IMO Publications and Documents - International Codes - Alarms and Indicators - Code on Alarms and Indicators, 1995 Resolution A.830(19) - Preamble


 This Code has been developed on the basis of the following principles:

  1 The Codefootnote is a recommendatory document primarily directed to ships covered by the International Convention for the Safety of Life at Sea, 1974 (1974 SOLAS Convention), as amended, the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating thereto (MARPOL 73/78), as amended, and associated codes (IBC, BCH, IGC, Gas Carrier, HSC, 1989 MODU, Nuclear Merchant Ships, Diving and IMDG Codes), 1993 Torremolinos Protocol and Guidelines for Inert Gas Systems (IGS) and Standards for Vapour Emission Control Sytems (VEC). Although alarms and indicators required by the dynamically supported craft and similar specialized ships are not specifically included, the Code can be used for guidance where appropriate, and in the future it could be extended to include these instruments. The Code can also be used for guidance for alarms and indicators fitted in excess of or in addition to those required by IMO instruments. It permits present practices in use in world fleets and provides flexibility for alternative methods. It is, however, intended to promote uniformity of the system between ships which will improve crew safety and training.

  2 The Code will benefit designers and operators by consolidating in one document the references to priorities, grouping, locations and types, including colours, symbols, etc., of shipboard alarms and indicators. Where the applicable IMO instruments do not specify the type and location of particular alarms, this information, as far as practicable, is presented in this Code to promote uniform application.

  3 Although preference was given to promoting consistency of terminology with IMO instruments, harmonization with the contents of IEC publication 92 - 203:1985, Electrical Installations in Ships. System Design - Acoustic and Optical Signals, was achieved as far as practicable.

  4 It is recognized that changing technology and future amendments to the IMO instruments referred to in the Code will necessitate changes to the Code itself. Accordingly, the Organization will review the Code as necessary taking into account both amendments to IMO instruments and future developments.

  5 Administrations are encouraged to give wide dissemination of this Code to shipowners, operators, designers and other interested bodies.
