1.1 This guide covers those symbols to be used to identify the location and operation of lifesaving equipment related to evacuation of personnel in the marine environment.

1.2 The symbols depicted should be used whenever graphic representation could assist personnel in locating their emergency stations and equipment and in the operation of such equipment.

1.3 Posters or signs depicting these symbols should be placed in conspicuous locations in the vicinity of survival craft, their launching controls, or other lifesaving equipment.

1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

3.1 The symbols depicted represent the following:

• 3.1.1 Equipment required during evacuation or rescue,
• 3.1.2 Location of muster stations in preparation for evacuation or rescue, or
• 3.1.3 The sequence of events for operation of survival craft.

3.2 Where station numbers are used with another symbol, they should be abutted to the right hand side of the other symbol.

3.3 Arrows may be used with any other symbol and, where feasible, should point in the direction of the equipment or station by being abutted to the symbol on the edge toward which the arrow is pointing.

3.4 Symbols that indicate station or equipment location should be in white on a green background (see Figs. 1 and 2).

3.5 Symbols that specify the operating sequence of survival craft should be in white on a blue background (see Fig. 3).

3.6 Symbols used as legends in station bills, lifesaving equipment arrangement plans or drawings, or other posters, need not meet the dimensions specified in 3.7.

3.7 Symbols used as markers to indicate the location of stations or equipment should be sized in accordance with 3.7.1 or 3.7.2.

• 3.7.1 Station number symbol dimensions should be a minimum of 150 mm in height by 75 mm in width (6 in. by 3 in.).
  • 3.7.1.1 Station number symbol dimensions of 600 mm by 300 mm (24 in. by 12 in.) should be used for greater prominence with the larger muster station symbol specified in 3.7.2.1.
• 3.7.2 Other symbol dimensions should be a minimum of 150 mm by 150 mm (6 in. by 6 in.), except:
  • 3.7.2.1 A muster station symbol with dimensions of 600 mm by 600 mm (24 in. by 24 in.) may be used in conjunction with the larger station number symbol specified in 3.7.1.1.

3.8 Symbols depicted in Figs. 1 and 2 should represent the survival craft that is actually provided.
