Introduction
This International Standard has been developed taking into account the existing IMO guidance on the subject as listed in the bibliography. The symbols annex A generally conform to the corresponding symbols given IMO Resolution, A 654(18) ([3] in the bibliography ) and A.760(18) ([7] in the bibliography ) but, as far as the symbols for fire plans are concerned, it was deemed necessary to carry out the following changes.
- The colour code given in ISO 14726-1 and ISO 14726-2 ([11] and [12] in the bibliography), has been adopted in order to render more evident the various types of systems/content of equipment present on board and for which the same symbol is used. This reduces the number of symbols referring to similar systems or equipment and consequently avoids cluttering of the plans.
- With the aim of rendering them more comprehensible to people on board and to shoreside fire-fighting personnel, who might be called to operate onboard a small number of symbols (e.g. the one referring to fire hydrant and hose) contained in IMO Resolutions A. 654 (18) have been modified in order to harmonize them with ISO 6309 ([10] in the bibliography) and ISO 3864. ([8] in the bibliography).
