Introduction
This document has been developed taking into account the existing International Maritime
Organization (IMO) guidance on the subject as listed in the bibliography. It is intended to supplement
IMO requirements and recommendations for arrangement of shipboard plans used on commercial
vessels complying with the International Convention for the Safety of Life at Sea (SOLAS), 1974, as
amended.
The symbols in Annex A generally conform to the corresponding symbols given in IMO Resolutions
[8] [9]
A.952 (23) and A.1116 (30) , but, as far as the symbols for fire control plans are concerned, it was
deemed necessary to carry out the following changes:
a) with the aim of rendering them more comprehensible to people on board and to shoreside fire-
fighting personnel, who may be called to operate onboard, a small number of symbols [e.g.
emergency equipment, muster and embarkation stations contained in IMO Resolution A.760 (18)
[7]
or IMO Resolution A.952 (23)] have been modified in order to harmonize them with ISO 24409-2
and with ISO 7010; and
b) damage control plan symbols have been introduced.

4 Pr eparation of plans
4.1 General
4.1.1 The structure and execution of the plans is the result of a thorough evaluation of the regulatory
compliance requirements, as well as an assessment of the relevant facilities for fire control, damage
control, escape and embarkation on lifesaving appliances.
4.1.2 The number and types of plans to be carried on board a particular ship must meet the
requirements of the competent authority.
4.1.3 In general, except for damage control plans, no illustration in any plan shall be made to a scale
smaller than 1:200 with minimum line point size of 4,5 for main vertical zone divisions, 2,25 for A and
B class and watertight divisions, and 0,75 for other lines. Large plans may be subdivided for clarity.

---------------------- Page: 8 ----------------------
ISO 17631:2022(E)
Damage control plans should be of a scale adequate to the size of the ship, or marine installation, in
order to clearly show the required content of the plan; in general, the plan shall not be made to a scale
smaller than 1:400.
4.1.4 The plans shall be in colour, and the detail of the symbols shall be clear.
4.1.5 Fire, lifesaving and damage control information should be placed in separate plans. However,
depending on the quantity of information to be taken into account for presentation, more than one
particular plan may be combined or consolidated, under the judgement of the competent authority,
provided that the combined or consolidated plans are properly legible. In addition, consideration may
be given to drawing up separate fire control plans for machinery spaces and deck areas.
4.1.6 A legend of symbols and explanations shall be a constituent part of any plan and contain a
complete list of the graphical symbols used in the plan, together with the appropriate explanations, and
may include, in some instances, additional special information such as the type of extinguishing media
used in the fixed fire-extinguishing system(s). As a rule, the legend shall be inserted in the appropriate
drawing. In case of a loose equipment – such as fire extinguishers, lifebuoys, or lifejackets – the legend
shall indicate next to each symbol the quantity of each particular item and, if needed, the arrangement
provided. For clarity, preferably only one font type should be used for text in plans. The minimum letter
point size shall be 12. The legend should preferably be placed at the right-hand side of the plan.
4.1.7 The information required shall be shown deck by deck; names of internal and external spaces
and cabin numbering shall also be shown.
4.1.8 The graphical symbols shown in Annex A shall be used when developing the plans. Table B.1
may be used for definitions of colour. A summary of all symbols included in Annex A is given in Table 1.
The graphical symbols used in plans and booklets shall be of suitable size to ensure that they remain
clear and recognizable, and shall not be smaller than 7 mm by 7 mm. Generally, symbols within the
drawing should not have a defining border. All symbols shall be positioned on plans in a manner to
clearly indicate the location on the vessel, but to avoid clutter, symbols may be placed outside the plan
with a dot and line to indicate the actual position. In this case, the graphical symbols shall have the
defined border, and the line shall have a point size greater than the minimum line point size adopted for
the general arrangement plan.
4.1.9 Plans, including those consolidated in the form of a booklet, shall contain the following
additional particulars:
a) ship's keel laying date or similar stage of construction, if applicable, as defined in SOLAS 74;
b) original method (e.g. for cargo ships, IC, IIC, or IIIC, as defined in SOLAS 74, as amended);
c) additional safety measures, if any;
d) dates and descriptions of any modifications to the ship which altered her fire, emergency and
damage control;
e) IMO number.
4.1.10 For passenger ship modifications carried out before 1 October 1994, if the dates and descriptions
of such modifications are not available, at least the fire safety construction method currently used in
the ship shall be stated. Where more than one method or a combination of methods is used in different
locations of the ship, this shall be specified.
4.1.11 Text in plans and booklets must be in the language or languages required by the competent
authority. Where more than one language is used on plans, these separate languages shall be indicated
with different font types. The languages used should take into account the requirements of the IMO ISM
[6]
Code with regard to the working languages of the ship.

ISO 17631:2022(E)
4.1.12 In order to improve legibility, the plans should not include information that is not directly
relevant to their scope and purpose.
4.2 Fir e control plan
4.2.1 The plan shall show the arrangement of the structural fire protection boundaries as per A.1,
and arrangement and location of fire-protection appliances as per A.2, together with means of access to
compartments, decks, etc.
4.2.2 The content of each fire locker shall be indicated in the legend. Symbols of items contained in a
fire locker need not be indicated on the deck views of the plan.
4.3 Structur al fire-protection plan
The plan shall show the arrangement and location of the structural fire-protection details given in
Annex A, symbols A.1.1 to A.1.11.
4.4 Means of escape plan
The plan shall show each means of escape within the ship, and identify assembly and embarkation
stations. Primary and secondary escape routes, as applicable, shall be identified in the plan by arrows
as indicated in Figures 1 and 2.
Figure 1 — Arrow for indicating the primary escape route
Figure 2 — Arrow for indicating the secondary escape route

4.6 Damage c ontrol plan
4.6.1 The plan is intended to provide clear and easy to understand information on the ship’s
watertight subdivision and equipment related to maintaining the boundaries and effectiveness of the
subdivision. In the event of damage to the ship causing flooding, proper precautions can be taken to
prevent progressive flooding through openings therein. Effective action can also be taken quickly to
mitigate and, where possible, recover the ship’s loss of stability.
4.6.2 The plan shall include tables in which the actions that must be done to seal any watertight
compartment are clearly indicated.
4.6.3 The information required shall be shown deck-by-deck; where relevant equipment is located on
other decks, the plan shall show appropriate sections of these decks within the drawing.
4.6.4 The plan should include a longitudinal section of the ship, plan views of each deck considered by
the damage control arrangements and transverse sections in order to show:
— the watertight boundaries of the ship;
— any mechanical means to correct list due to flooding;
— all internal watertight appliances including, on ro-ro ships, internal ramps or doors acting as
extension of the collision bulkhead and their controls and the locations of their local and remote
controls, position indicators and alarms. The locations of those watertight closing appliances which
are not allowed to be opened during the navigation and of those watertight appliances which are
allowed to be opened during the navigation should be clearly indicated;
— the locations of all shell doors, including position indicators, leakage detection and surveillance
devices;
— the locations of all weather-tight appliances in local subdivision boundaries above the bulkhead
deck and on the lowest exposed weather-decks, together with locations of controls and position
indicators, if applicable;
— the locations of all bilge and ballast pumps, their control positions and associated valves;
— the indication of compartments and decks;
— indicate whether an access point represents both up and down or only way transit (at the bottom of
the stair or ladder);
— the indication of all hatches;
— any other relevant pumps and valves referred to the damage control booklet.
4.6.5 All stairs, ladders, watertight doors and hatches for access to, or escape from, each watertight
compartment should be clearly marked and identified by the compartment number and stair number as
shown in A.5.2 to A.5.4.
