    SCOPE

    1. This DEF STAN applies the policy of the Secretary of Defence through the Ship SafetyBoard (SSB) to comply with the Health and Safety legislation where it applies for safety signsand colours. When it does not apply or exemptions have been granted from specificregulations it is Ship Safety Board policy to have Ship Safety Management Systems (SSMS)which are as good as statutory requirements.

    2. It is to be applied as required by any Ministry of Defence contract where safety signs arespecified and is applicable to:

    a. Surface Ships, Submarines, RFAs and miscellaneous small auxiliaries;b. Ship Systems and Equipment and Weapon Systems and Equipment.

    Shore establishments are to follow Statutory Instrument (SI) 1996 No 341 in itsentirety.

    3. Accordingly, as an example of best practice, the Health and Safety (Safety Signs andSignals) Regulations 1996 and relevant declarations under IMO SOLAS treaties are to beapplied to Surface Ships, Submarines, RFAs and miscellaneous small auxiliaries and this DefStan details or provides reference to approved permanent safety signs, pictograms,supplementary signs, colours and methods of marking to be used.

    4. It refers to many of the hazards that can be met in a ship environment and statesrequirements for marking equipment and structures where considered necessary for health andsafety purposes.

    5. It does not provide information on temporary health and safety signs required during thebuild or refits of ships or equipment. Such signs are the responsibility of the shipbuilder orship repairer.

    6. It does not provide information regarding the marking or the packaging of any materialincluding ammunition or of the ammunition itself.

    7. This Def Stan enforces the requirements of the various Regulations. The Def Stan alsohighlights specific instances of its use, but the instances quoted do not necessarily constitutethe full requirement.

    Additional Information

    25. The general requirements for format and signs are to be taken from this Def Stan. Forindividual hazards, the requirements are to be obtained from the specific Def Stan referring tothe Equipment or System concerned. Where it is suspected that an equipment Def Stan maybe out of date, the individual Def Stan sponsor or the sponsor of this Def Stan is to becontacted for further guidance.

    Safety Sign Policy

    26. The following is part of the Foreword in JSP 430 by the Secretary of State for Defence:

    a. As stated in my Health and Policy Statement dated February 1996 I require that wherethe MOD has been granted exemption from the specific regulations, health and safetystandards and arrangements will be, as far as is reasonably practicable, at least as goodas those required by statute. I have also directed the Second Permanent UnderSecretary of State to notify me where further means are necessary to meet legislativeor other requirements.

    b. To assure the safety of MOD shipping activities the Ship Safety Board (SSB) has been

    established and a Ship Safety Management System (SSMS) has been introduced. TheSSMS, which covers all MOD owned and operated vessels including ships undercommercial management or on charter to perform MOD business world-wide, aims toreduce the levels of risk of accident death or injury to the crew or other parties anddamage to the environment to as low as reasonably practicable.

    27. JSP 430 describes in detail the methodology of the SSMS and how hazards should bedealt with.

    a. JSP 430 provides a list of key hazards and describes how hazards in general are tobe controlled in order of priority as follows:

    1) removal of the hazard;2) substitution of the hazard (to minimise risk by use of alternative

    substances/procedures);3) mitigation/control of the hazard (e.g. the use of physical protective

    measures such as interlocks or guards);4) provision of personal protective equipment or additional operator training;5) provision of safety signs to warn of the hazard.

    b. Safety signs are only to be used when all other controls have been considered but

    the hazard remains.

    1. PERFORMANCE SPECIFICATION

    Related Documents: JSP 430

    a. Safety signs must be clear, legible and unambiguous in their content in allconditions.

    b. Safety signs must be large enough to view from the maximum distance at

    which the hazard exists. c. Safety signs should only be used where it can be proved that it is not

    reasonably practical to remove the hazard by another means (see JSP 430). d. Safety signs must also be used to highlight any hazards with residual risk after

    appropriate mitigation to as low as reasonably practical.

    2. NATIONAL/INTERNATIONAL REGULATIONS

    Related Documents: BS 5378, BS 5499, DEF STAN 05-34, SI No 341, JSP 430, L64-IMO SOLAS

    2.1 Definitions

    a. The following definitions are contained in Statutory Instrument No. 341/1996and are repeated for convenience:

    Emergency Escape or FirstAid Sign

    A sign giving information on escape routes oremergency exits or first aid or rescue facilities.

    Illuminated Sign A sign produced by a device made of transparent ortranslucent materials which are illuminated from theinside or the rear in such a way as to give theappearance of a luminous surface.

    Mandatory Sign A sign prescribing behaviour.

    Prohibition Sign A sign prohibiting behaviour likely to cause a risk tohealth or safety.

    Safety Colour A colour to which a meaning is assigned.

    Safety Sign A sign referring to a specific object, activity or situationand providing information or instructions about healthor safety at work by means of a signboard, a safetycolour, an illuminated sign, an acoustic signal, a verbalcommunication or a hand signal.

  • Def Stan 02-784Issue 5

    10

    Signboard A sign which provides information or instructions by acombination of geometric shape, colour and a symbolor pictogram and which is rendered visible by lightingof sufficient intensity.

    Symbol or Pictogram A sign which describes a situation or prescribesbehaviour and which is used on a signboard orilluminated surface.

    Warning Sign A sign giving a warning of a risk to health or safety.

    Fire Safety Sign A sign (including an illuminated sign or an acousticsignal) which:a. provides information on escape routes and

    emergency exits in case of fire;b. provides information on the identification or

    location of fire-fighting equipment; orc. gives warning in case of fire.

    b. The following useful definitions are contained in L64 and are repeated forconvenience:

    Safe Condition Sign A safety sign that provides information about safeconditions.

    Supplementary Sign A sign with text only that may be used in conjunctionwith a safety sign in order to provide additionalinformation.

    2.2 Concept of Safety Signs

    a. Notwithstanding the exclusion contained in the SI No.341 regarding vessels,(DEF STAN 05-34 Section E refers) Safety Signs employed on ships are to bealigned with those enforceable ashore to assist persons in recognising similarsigns when moving between shore establishments and ship.

    b. If existing signs are proven to comply with BS 5378 (or in the case of fire

    safety signs with BS 5499) SI No. 341 does not require any change to thosesigns.

    c. The IMO SOLAS requirements encompass the requirements for safety signs

    onboard Merchant cargo and passenger vessels. Where these requirements aremore indicative of safety at sea they have been included. However whenconsidering a hazard, and having established that a safety sign is required, theIMO regulations should be consulted to ensure that the appropriate details areincluded in the hazard warning selected.

    d. Safety signs must only be used when it is impracticable to design-out thehazard.

  • Def Stan 02-784Issue 5

    11

    e. Overuse of safety signs must be avoided. Sign blindness can be caused if too

    many signs are used in the same area to describe one or more hazards. (seesection 2.2.3.d).

    2.2.1 Provision and Maintenance of Signs

    a. SI No. 341 requires that safety signs are provided (or are in place) andmaintained in circumstances where risks to health and safety have not beenavoided by other means, e.g. engineering controls or safe systems of work.

    b. JSP 430 requires that provision of a sign to reduce a risk to as low as

    reasonably practicable (ALARP) can only be taken after other forms ofmitigation have been discounted.

    c. Signs are to be maintained to ensure that they are clearly visible and that they

    warn of the hazard effectively in all levels of lighting from the maximumdistance at which the hazard exists.

    2.2.2 Types of Signs

    a. There are five types of signs, together with a supplementary sign, which usestandard colours and shapes appropriate to purpose, i.e. prohibition, warning,mandatory, emergency escape or first aid and fire fighting. Supplementarysigns must only be used in conjunction with safety signs. Danger identificationmay also be achieved solely by colour or a combination of colours.

    b. The intrinsic features of the types of signs, general examples of use and

    permitted colours are described in Part II of SI No. 341. The basic details are:

  • Def Stan 02-784Issue 5

    12

    Prohibitory:a. round shapeb. black pictogram on a white

    background, red edging and diagonalline (the red part to take up at least35% of the area of the sign)

    Warning:a. triangular shapeb. black pictogram on a yellow

    background, black edging (the yellowpart to take up at least 50% of thearea of the sign)

    Mandatory:a. round shapeb. white pictogram on a blue

    background (the blue part to take upat least 50% of the area of the sign)

    Emergency Escape, Lifesaving or First Aid:a. rectangular or square shapeb. white pictogram on a green

    background (the green part to take upat least 50% of the area of the sign)

    Magazine and Fire Safety:a. rectangular or square shapeb. white pictogram on a red background

    (the red part to take up at least 50%of the area of the sign)

    Supplementary:a. rectangular or square shapeb. text colour to be the same as the colour of the pictogram on a background

    of the same colour as the safety sign (see L64)

    Note - a supplementary sign can only be used in conjunction with the safety sign andit must be part of or immediately adjacent to the pictogram.

    2.2.3 General Considerations

    a. Safety information is to be conveyed using signs containing simple pictogramsand containing only essential details. The signs may be supplemented with

  • Def Stan 02-784Issue 5

    13

    text to aid understanding (see L64). However the use of text should beminimised, this should be borne in mind especially where there is an exportsales potential.

    b. Where no appropriate pictogram exists, then the use of a general sign as

    depicted in Annex E, together with text on a supplementary sign is to beconsidered. The safety sign and supplementary sign may be combined on onemarker plate. If a new pictogram is considered necessary where no appropriatepictogram exists then the proposed new pictogram is to be referred to thesponsor to obtain general concurrence and codification as necessary prior toinclusion in this Def Stan.

    c. The wording of signs is to be consistent with purpose, e.g. do not is not to be

    used on a warning sign but reserved exclusively for a prohibition sign. Noinformation other than safety is to be included on a safety sign. Every attemptmust be made to ensure that signs are clear, concise and unambiguous as totheir intent.

    d. Care must be taken to avoid too many signs in close proximity, i.e. sign

    blindness. Signs are only effective if they can be seen and understood.Therefore if several signs are required (at a single location) consideration mustbe given to combining the signs into a multi-purpose sign.

    2.2.4 Choice of Materials and Siting a. The material choice for safety signs must be considered to ensure that it is a

    safe material for the environment. For example, some plastics when meltingor on fire will release toxic fumes and should not be used in closedenvironments, e.g. BR1326A for submarines or a NBCD citadel environmenton a surface ship.

    b. For equipment, the safety sign is to be attached to the last major barrier or

    cover to be removed before the hazard is exposed, or adjacent to the nameplateif the item has no cover. Exceptionally there may be a requirement to secure asign within the equipment under the last cover. EPMs within the appropriateIPT are to determine the form of such signage, within their safety cases

    2.2.5 Preferred Sizes

    a. SI No. 341 does not give any specific details on the size of safety signs andlettering, except that they can be clearly seen and the hazard identified.Appropriate guidance is given in Section 5.

    2.2.6 Indication of Safety Colour

    a. Where a safety sign is to be used the type of sign shall be identified e.g.prohibition, mandatory etc., and the appropriate colours as described in section2.2.2 are to be used.

  • Def Stan 02-784Issue 5

    14

    b. In certain instances, e.g. indication of the perimeter of danger areas, the degreeof safety may be indicated by painting a strip of the appropriate colour orcolours with or without using a pictogram or notice, for example a plainyellow line represents RADHAZ hazards whilst a yellow and black linerepresents the hazards created by moving objects.

    c. Red is used to indicate certain shutdown devices and fire-fighting equipment.

    3.1 Hazards Which May Be Met

    a. This section is intended as a guide to designers of ships and equipment fittedin ships regarding likely hazards that may be encountered. The reader shouldbe familiar with the contents of JSP 430 and this document should be referredto for more information on policy and guidance. Signs are to be used asappropriate mitigation to hazards identified as part of the SSMS.

    b. Hazards will be identified from a risk assessment conducted by the WPM or

    EPM. A general prompt list of some potential hazards which may be met in aship environment and which may require attention to be brought to them by asign are listed below, but not necessarily in order of importance:

    1) fire and explosion (incl. magazine safety features); 2) toxic and corrosive effects; 3) radiation effects, ionising and non-ionising, (including ultra-violet and

    infra-red, from lasers and similar equipment, and radio frequency); 4) electric shock; 5) pressurised gases and fluids; 6) movement or rotation of large masses; 7) obstructions, dangerous deck configurations, hazardous weather deck areas

    in bad weather; 8) noise and vibration; 9) inhalation hazards; 10) dust; 11) high and low temperature; 12) handling and lifting of heavy items.

  • Def Stan 02-784Issue 5

    16

    c. Some examples where signs may be of use to indicate an action is required to mitigateagainst a potential hazard are given in the non-exhaustive list below:

    1) items of equipment which may rotate or move (often without warning): i) gun mountings and directors, launchers, hoists, cranes, davits, lifts,

    rotating aerials and trackers (see section 4.1.8); ii) fork lift and other trucks, aircraft operational areas (see section 4.2.2); 2) galleys, workshops, maintenance areas, laundries containing various types

    of machinery (see appropriate sub-sections of 4.1 and 4.2); 3) compartments or areas containing hazardous equipment, services or

    substances, e.g. ammunition, flammable substances such as paint and oils(see section 4.2.9);

    4) equipment which contains a hazard within it, dangerous voltages,

    dangerous substances, ionising and non-ionising radiation, acousticradiation or vibration, and lasers (see appropriate sub-sections of 4.1 and4.2);

    5) dangerous obstructions such as valves, hand wheels or levers; 6) exposed walkways in rough weather; 7) hazardous deck areas such as unguarded accesses through decks; 8) piping and equipment containing high pressure air, fluid or gases.

    3.1.1 Hazardous Stores

    a. Details of stores which are listed as hazardous are included in JSP(F)395/HSIS.

    3.1.2 Accident Prevention

    a. In order to minimise danger concerning the above (and other) hazards,accident prevention measures should be considered as part of the SSMS underJSP 430 and the vessels Safety Case. Due consideration should also be givento specific guidance within BR9147 and BR2000(20) and within the shipsstanding orders and supporting Ships Safety Log. This Def Stan is concernedonly with the safety instructions which may be required as part of theseaccident prevention measures.

  • Def Stan 02-784Issue 5

    17

    3.1.3 Choice of Sign Materials, Sizes and Siting

    a. In general the same considerations regarding choice of material, e.g. metal ornon-toxic plastics, sizes and siting are to be applied as those required formarker plates for other purposes (see Def Stan 02-723) unless stated otherwisein this Def Stan. Only non-toxic plastics should be used in a closedenvironment (see Def Stan 02-705, BR1326A).

    b. Typically signs are available as adhesive vinyl, rigid plastics, trafolite andplastic tapes.

    3.1.4 Procurement and Codification

    5. CORPORATE EXPERIENCE & KNOWLEDGE

    Related Documents: JSP 430

    5.1. General

    a. When considering the applicability of safety signs to a situation it is importantto ensure that a positive safety culture is in place. A positive attitude towardssafety will ensure the smallest possible risk of accident or injury andmaximum understanding of the safety signs supplied. The simplest way tochange safety attitudes is by management example and personnel training.The introduction of JSP 430 has provided a framework to develop this safetyculture.

  • Def Stan 02-784Issue 5

    31

    b. It is MoD policy to have levels of risk and safety management systems whichare at least as good as statute. There will always be exceptions on RN Shipswhere statute cannot be met. In such cases, a justification should be recordedwithin the safety case to prove that appropriate mitigation to ALARP (As LowAs Reasonably Practicable).

    c Research has proven that although between 66 to 90% of people will notice awritten warning or sign, only half of them will actually read what it says. Inmany cases, the need for a warning indicates poor design. Improving thedesign of an item can make the need for a warning obsolete, or at least makethe advice much easier to follow.

    5.2 Requirements For Safety Signs

    5.2.1 Procedures For Identification Of A Hazard

    a. For new design and immature projects hazards should be identified throughstructured brainstorming sessions (such as SWIFT & HAZOP) and as part ofother formal design assessments and reviews. Ideally any hazards so identifiedshould be negated by design change and so down the mitigation hierarchy;where it is not possible to achieve this it may be necessary to protect personnelfrom the hazard by identifying an appropriate sign. The sign must be capableof being quickly and easily understood. A safety sign must not be used in lieuof achievable design changes, i.e. reducing the hazard to as low as reasonablypracticable (ALARP), and must not compromise any other design aspects.Signs can also be used to enforce safety features such as the use of safetyguards and/or procedures.

    b. Where an existing hazard is identified onboard an in-service ship, it should bebrought to the immediate attention of the WPM or EPM in order that allnecessary mitigation steps can be taken. As the final step in this process it isthe responsibility of the ships CO and designated Safety Officer to ensure thaton identification of the hazard the appropriate safety sign is used until othermitigation techniques can be implemented or a permanent safety sign issupplied by the WPM or EPM and incorporated into the ships safety signdatabase.

    c. If a hazard is identified during refit the WPM or EPM is to be notified in orderthat all necessary mitigation steps can be taken. Refit hazards are classed asthose introduced to the vessel through the removal or addition of equipment.Temporary hazards produced by the refit dockyard, e.g. temporary cable runs,trip hazards caused by items of equipment out of place, etc. are theresponsibility of the refit dockyard and should be highlighted using temporarysigns supplied by them. Where it is considered that these are inadequate therefit project manager should be informed.

  • Def Stan 02-784Issue 5

    32

    5.2.2 Positioning Of Safety Signs

    a. When identifying the location of safety signs, consideration should be given tothe hazard or feature that they are marking and its position. For example, afirst aid box which should incorporate a sign of a white cross on a greenbackground on it does not need an adjacent first aid sign provided that theintegrated sign is clearly visible. However if it is obscured, or in a cupboard,an additional safety sign should be placed in a prominent position indicating itsexact location.

    b. Signs should be :-1) located when and where needed, so that they grab the attention.2) in a conspicuous position (ideally in line of sight).3) in a suitable format (brief, understandable and attention

    grabbing)4) annotated only with the information needed.

    c. Direction signs, for example escape signs, should form a continuous route but

    should be kept to a minimum in order to avoid confusion. However signs must bespaced so that they can be seen in poor visibility and as a minimum sited on doorsor hatches and should indicate changes in direction. Where a primary andsecondary escape route is available each route must be clearly identified to ensurethat the correct route is used. There may be different escape routes depending onwhether the vessel is in harbour or at sea, these should be clearly identified.

    d. Standing Orders and Work Instructions are to be considered when reviewing the

    requirement for safety signs. Where the hazard is non continuous, e.g. loadingstores etc., a permanent safety sign may not be required. Suitable alternativemitigation may include areas are always manned whilst the hazard is present orthat appropriate temporary safety signs should be placed as part of operatingprocedures.

    5.2.3 Overuse Of Safety Signs

    a. Sign Blindness is an important consideration for the designer/surveyor and iscreated by the presence of to many signs in any one position. Sign Blindnesscan lead to confusion or to the information being ignored. If the hazard orhazards indicated are unclear then the risk of injury or accident is significantlyincreased. In order to establish whether or not a safety sign is required at theaccess to a compartment the following points must be considered:

    1) What are the hazards contained within the compartment/area underconsideration?

    2) Are these hazards global to the compartment or specific toequipment?

    3) What is the level of risk :-i). under normal operating conditions?

  • Def Stan 02-784Issue 5

    33

    ii). in emergency situations, or action stations e.g. fire, floodetc.?

    b. Hazards should be considered individually and recorded in the vessel hazardlog. The IPTL/surveyor should use the hazard log and any previouslyconducted workplace risk assessments as a baseline to establish which signsare to be placed and their positions. The ships signs register records theresolution of this process for in-service ships and should be created as part ofthe Ships Safety Case (in-conjunction with other safety equipment registers)for new vessels. In prioritising signs to locate at or near hazardous areas,consideration should be given not only to the nature of the hazard but also tothe circumstances in which the hazard occurs. Hazards which are consistentlyoccurring, e.g. hot surfaces, require to be notified at all times. However,hazards which may occur as the result of particular circumstances andemergency situations, e.g. the presence of CO2 after a hand-applianceextinguished fire, need not be notified. The awareness of these hazards canonly be addressed through training of personnel and the practising andexercising of emergency procedures.

    c. Studies have proven that signs are most effective if warnings containinformation on possible injuries or consequences. This helps motivate users toknow why they should comply. Therefore effective signs should indicateactions to avoid a hazard in a reliable and timely manner. Personnel are mostlikely to comply with Mandatory signs if safety equipment (gloves, masks etc.)is located close at hand, or supplied with the warning.

    d. Signal words such as DANGER, WARNING and CAUTION are effectivesince they help personnel perceive a particular product or drill to be morehazardous. DEADLY and POISON are rated the most extreme signal words bymost studies.Remember: Too many warnings or signs encourage personnel to read only thefirst few. Place important information at the top of multiple sign-boards(Annex E, para E7) and restrict the number of symbols and information to theminimum required to avoid information overload.

    e. Warships are a hazardous environment in which to work, there is a real dangerthat too many signs could be used. Sound engineering and operationaljudgement must be applied to certain areas of the ship. There are areas of thevessel which have specific design features which could be classed as a hazard,for example the sill of watertight doors could be classed as a tripping hazard.The mitigation for incorporating these tripping hazards is that they are requiredin order to maintain watertight integrity. Therefore hazards which areexceptions to the norm should be highlighted e.g. rather than a sign on all sillsthose that do not conform to the standard design should be provided with asafety sign or by hazard warning tape.

    f. Signs are most effective when:1) risks of non-compliance are perceived to be serious or highly likely

    to occur.

  • Def Stan 02-784Issue 5

    34

    2) personnel believe that they will be personally affected by theconsequences.

    3) personnel are unfamiliar with an equipment or situation.4) those around them are complying with the instruction (safety

    culture).5) it is easy to comply with the instruction e.g. PPE is close at hand.6) it is believed that compliance will return a real personal benefit

    (safety culture)

    5.3 Implementation of Safety Signs

    a. Safety signs must not be obstructed at any time. Where a permanentconfiguration change would obscure the sign the A&A guidance must includerepositioning of the sign.

    b. Where a supplementary text sign is used in conjunction with a pictogram, thetext must be consistent with the authority of the pictogram sign.

    c. It is recommended in statutory regulations that all escape sign are to bephotoluminescent; this is a restricted option when considering RN vessels (seePara 4.2c. of this Def Stan). The night-time visual signatures of the shipshould not be compromised by the use of safety signs.

    d. Figure 5.1 illustrates some typical sign sizes dependant upon viewingdistances.

    Viewing distance3.3m (letters 10mm)

    Viewing distance5.0m (letters 11mm)

    Viewing distance10m (letters 22mm)

    Viewing distance20m (letters 44mm)

    Figure 5.1 - Viewing Distances For Safety Signs

    e. Where possible the approved sizes should be used, however, due to thelikelihood of restrictive space on RN vessels smaller signs may be necessary,ensuring that the hazard is still highlighted from a suitable distance. Forexample a RADHAZ warning sign must be visible from all accesses to the

  • Def Stan 02-784Issue 5

    35

    hazard and from a safe distance from the tape marking the hazard boundary asillustrated in Figure 5.2

    Figure 5.2 - An Example Of Safety Sign Positioning

    NOTE: It is the obligation of the designer to ensure that sufficient signs areprovided to highlight the hazard from all access points, and the surveyor thatthey are installed at the intended positions. However they can be positionedoutside the hazard warning tape or even at access points.

    f. If a supplementary text sign is to be used alongside a pictogram the letteringshould be a minimum of 10mm, increasing with the viewing distance of thesign.

    g. Everyone perceives risk differently. Over-confidence, optimism or over-familiarity can reduce an individuals appraisal of a hazards significance.Risks will generally be underestimated in our own work and overestimated inothers. Personnel will respond to warnings if they are alert and seekinginformation, because they expect a hazard to be present or because pastexperience or training indicates that such information may be needed. It isvital not to overload any user with information. It is human nature to be moreconcerned with getting the job done than to be consciously aware of health andsafety consequences. Critical tasks require personnel to switch to a moreconscious and focused thinking about inherent risks. Signs can help with thisfocus when applied correctly.
