Ship's safety signs

Introduction A ship is the integration of industrial products manufactured by' assembling a variety of parts

from suppliers in diverse fields. For these products, safety signs are used to protect operators and other related

persons agamst hazards wrth speclfic relauon to Product Lrabihty (slmplified to "PL"). Uses of safety signs in

forms differing from product to product and from manufacturer to manufacturer are considered to hamper

understandings by those related persons, causing confusions among them. This Japanese Industrial Standard

has been established to promote standardization ofsafety signs used in ships and to help those persons concerned

understand them.

l. Scope This Japanese Industna] Standard speclfies the safety slgns fitted to ships mobile offshore dnllmg umts and equrpment camed onboard (heremafier referred to as "ships"). This Standard includes the

objectives of safety signs, definitions of terms, symbols and colours used for safety signs, and guidelines for

design (forms and materials), fixing positions and fixing procedures for safety signs.

The safety signs that are made obligatory under laws and regulations shall be considered to be outside this

Standard, and priority shall be given to them.

3.

a)

b)

Definitions The following definitions shall apply to the major terms used in this Standard.

safety sign The sign that conveys general safety aiert messages obtained by combining colours shapes, and conveys specific safety alert messages by adding pictorials (1) or text messages (2).

Note (1) (2): (See 5:2..2 and 5.2.3)

safety colour The colour that has features (3) with safety significance.

Note (3) : The definitions of the features of safety colours shall be in accordance with Annex A to JIS Z 9 10 1 .

and

4. Basic matters related to safety signs 4.1 Objectives of safety signs The objectives of safety signs fitted to ships are to alert persons to existing

or potential hazards, and all or part of the following elements a) through d) shall be included in a safety sign.

a) Class of hazards "DANGER", "WARNING", "CAUTION." (See 4.2)

b) Type of hazards Flammablc material, high temperature, high voltage, etc.

c) Consequences when alert is ignored Fire, burn, electric shock, etc.

d) Measures to avoid hazards Operational instructions and prohibitions

4.2 Class of hazards and definitions Hazards assigned to ships' safety signs are classified into the following three classes using safety alert signal words according to the degree ofhazard and probability:

a) DANGER This indicates an extreme hazard that may lead to a death or serious injuries, ifnot avoided. This shall be used for the situation of an extreme hazard and should not be used excessiveiy (4).

b) WARNING This indicates a hazard that may probably lead to a death or serious injuries, ifnot avoided (4) .

c) CAUTION This indicates a hazard that may probably cause light or medium injuries, ifnot avoided (4).

Note (4).: The safety alert signal words ~DANGER", "WARNlNG- and "CAUTION" shall be used only when

there is a hazard, which directly affects human bodies. They shall, however, not be used when a

hazard may lead to damage to properties only, without endangering human bodies. Operational

safety signs for use when only physical damage is expected are shown in Annex 5 for reference.

F OO90- , 999

4.3 Recipients of safety alert of safety signs The recipients of safety alert of safety signs shall be as

follows:

a) Ship and ship machinery operating persounel (those engaged in direct operations of ships, ship machinery and equipment, and supervisors)(hereinafter referred. to as "operators").

Persons related to carriage and installation of ship machinery and equipment

Persons related to operations and maintenance of ship machinery and equipment b) Persons other than operators (s)

Note (5): In the case of ships, operators are, in many cases, Iimited specialists, which differ in terms of

occupational characteristics from those operators of consumer goods, and, therefore, use of technical

terms may be permitted to some degrees. If, however, there are possibilities that persons other than

ship machinery and equipment operators might have access to hazards, it is preferred that safety signs

are in readily understandable messages (refraining from using special ship terms).

5. Safety signs

5.1 General precautions for safety signs a) Location Safety signs shall be securely fitted at conspicuous places in the vicinity of locations where

hazards exist or in the proximity ofthe inlet of a space where hazards exist.

If thcre are a plurality of hazards of the identical element and it is diffrcult to fix safety signs individually

to each ofthem, they may be displayed in an integrated mauner.

b) Conspicuousness Safety signs shall be in a geometric shape and size so that they can be understood at

one sight, and be compatible with ships, ship machinery and equipment. Colours of safety signs for use

are either in red, orange-red or yellow and it is preferred that colours in the same colorimetric group are

not used for shipboard paintings.

c) Effectiveness Safety signs shall, as part ofaship, be effective throughout the service life ofthe ship. It

is necessary that they do not detach from the ship's structure or do not become obscure by discoloration,

and it is preferred that their service life is the same as the ship's service life. When the maintenance of

their durability is difficult due to heat, stain or others, safety signs shall be dealt with as those consumable

items, and renewals should be made obligatory. Explanatory notes in this regard shall be stated in

Operator's Manuals.

d) Number of safety signs Safety signs shall be limited to cases where reasonable security of safety is structurally difficult, and it is preferred that their number is not excessive.

5.2 Composition of safety signs Safety signs sha]1 be composed of either all or part of the following a)

through d):

a)

b)

c)

d) 5.2.l

"CAUTION

safety alert signal words (hereinafier referred to as "signal words")

safety alert symbols (hereinafter referred to as "alert symbols")

hazard description/avoidance pictorials (hereinafter referred to as "pictorials")

text message Alert symbols Alert signals correspond to the three signal words: "DANGER" "WARNlNG" and

,,

Alert symbols used for ships' safety signs and prohibition/instruction symbols are as given in Tables 1

and 2.

F 0090- 1 999

Table I Alert symbols used forsafety signs

Table 2 Prohibrtron/mstructlon srgns used for safety srgns

5.2.2 Pictorials Pictorials are graphic presentations of the type and result of a hazard and its avoidance

method, and are used without or in combination with text messages. Pictorials help operators visually understand the content of hazard, and therefore, it is preferred to use pictorials as far as practicable.

When a plurality of hazards coexist, priority shall be given to the higher hazard.

Examples of pictorials applied to ships' safety signs are shown in Attached Fig. l.

5.2.3 Text messages Text messages describe the type and result ofahazard and its avoidance method. Text messages shall be short, simple and clear, and hazard avoidance method shall be described in an imperative

sentence. Ifdescribing text messages is difficult due to the limited space available or the need ofusing multiple

languages, detailed explanations may be stated in Operator's Manuals providing that it is so noticed (see 5.5).

5.3 Formats and dimensions of safety sign Safety signs shall, in principle, be divided into the following

three panels.

a) Signal panel (S) Alert symbols and signal words are included.

b) Pictoriai panel (P) Pictorials are included.

c) Message panel (M) Text messages are included. 5.3.1 Basic formats and dimensions of safety signs The basic formats and dimensions of safety signs are

shown in Fig. l.

5.3.2 Modification of formats and dimensions The formats and dimensions ofsafety signs may be modified as appropriate according to conditions such as the type and size of a ship.

a) The dimensions of a safety sign shall be such that it is understandable within the operating range of a ship.

As a rule of thumb, the area of a safety sign shall be as shown below in accordance with JIS Z 9 1 O I : L2

A~ 2000 where

A : minimum area of safety sign (m2)

L: maximum distance (m) from a place safety sign is understandable, L ~ 50 m

b) When all signals, messages and pictorials that are shown in 5.2 a) through d) are difficult to be displayed

in the divided three panels due to the ship's size and restrictions at the location of safety signs, they may

be modified as necessary, either by omitting or integrating panels in the smaller size according to the

methods shown in the foliowing I ) through 5).

l) Two panels (s + M) Use the signa] panel and message panel, omitting the pictorial panel. (See Fig. 2)

2) Two panels (s + p) Use the signal panel and pictorial panel, omitting the message panel. (See Fig.

3)

In this case, the type and the consequence of a hazard, and the route of evacuation shall be clear

only through the pictorial panel alone.

3) Two panels (P + M) Use the pictorial panel integrated (6) with alert symbols, omitting the signal

panel. (See Fig. 4)

4) Two panels (s + p and M) Use the signal panel in combination with pictorials and text message. (See Fig. 5)

5) One panel (P or P and M) Use pictorials (6) jntegrated with alert symbols only, or use pictorials

(6) integrated with alert symbols and text message in combination only. (See Fig. 6)

Note (6): In the case of integration of alert symbois and pictorials, the exclamation mark shall be

substituted with a pictorial.

For indicating fires or explosions, Ted may bc used.

When a signal panel is not provided, pictorials integrated with alert symbols shall be used. Ifasignal

panel is provided, alert symbois integrated with pictorials may not be used, but pictorials only.

The slash line in a circle symbol and the crossing symbol shall be in red as well.

When indicating a fire or an explosion, white may be used.

5.5 Language for use The language that is instructed by the shipowner, taking into account the trade areas

of a ship and the nationality of crewmembers, shall be used.

When a plurality of languages are used, the number of languages shall be limited to two so that text

messages can be suffilciently scrutinized, Ifit is necessary to use three or more languages, ships' safety signs

shall be such that alert symbols are provided in combination with a text message stating that "Read Operator's

Manua]" or pictorials ofthe same implication, and provide detailed expianations in the Manual.

Explanatory notes on the safety information in an Operator's Manual are shown in Annex 4.

of the

The basic principle of ships is that they can be used safely. For securing the safety of ships, priority shall,

therefore, be given to design assessments and countermeasures for safety, and it is preferable to limit safety alert

descriptions only when solutions are difficult merely by design considerations or when security of ships' safety is

difficult merely through design efforts. It is desirable to make the number of safety alert signs for ships, in

particular, as fewer as possible.

Ships' safety assessments and safety measures shall be developed by the following procedures.
