3. Objective

The objective of this document is to set out Regulations for a common Colour CodeIdentification System for Pipework, which shall specify the mandatory safety colours to beadopted by QP, Joint Venture Groups and Other End-Users, for the identification of the contentsof the pipework, and hence the potential hazards. The system is intended to address fire andsafety concerns within all Ras Laffan Industrial City On-Plot and Off-Plot Facilities and provide

improved line identification for plant operators.

4. Introduction

Pipelines are an important means of conveying liquids, gases, steam and air. It is howeverimpossible to find out what a pipeline contains from its external appearance. As the number andcomplexity of piping installations within any facility increase, so does the need for a system toquickly and easily identify pipework, pipelines and their contents. Failure to correctly identify theservice of a pipework system can and often has been shown to be the cause of plant upsetsand safety incidents. Effective identification of all pipework should therefore help to eliminate

this potential source of such problems.

In-line with QP/RLC's Loss Prevention Philosophy and commitment to make its facilities safe, itis therefore required that all pipelines shall be clearly colour coded and labelled, in accordancewith the Regulations as defined herein together with the referenced standards.

5. Colour Code Identification Band System

5.1.QP Specification QP-SPC-L-002 requires all pipework of 2 diameter and larger, apartfrom Fire Fighting System pipework, to be finished in either Light Grey, BS 4800 Ref.10-A-03 or White, BS 4800 Ref. 00-E-55, along its entire length. This shall be referredto as the decorative colour.

5.2.The nature of the pipe contents shall be identified by means of a Three Band ColourCode Identification Band System (CCIB), as specified in BS 1710. The outer bands,which will be the same colour, are the Basic/Primary Identification Bands (PIB) and themiddle band is the Safety/ Secondary Identification Band (SIB). The arrangement isshown in Figure 1.

5.3.The Basic/Primary Identification Band (PIB) colour determines the type of fluid, e.g. Oil,Gas, Chemical or Water. BS 1710 suggests Basic Identification Colours for differenttypes of fluid. These colour conventions have been adopted with some exceptions, asdetailed in Section 6 and Table 1.

5.4.A Safety/Secondary Identification Band (SIB) colour is added to the middle of the PIB,to identify the fluid conveyed more precisely. The SIB, used in conjunction with thePIBs, is designed to provide a unique combined Colour Code Identification Band(CCIB) for each fluid that is being conveyed. These are detailed in Section 7 and Table3.

5.5.All PIB and SIB Colours used shall comply with the appropriate BS4800 ColourReference Numbers that have been specified in Tables 1 to 3. Colour names are givenfor guidance only.

5.6.The PIB and SIB width requirements shall be the same for all pipe sizes over 6diameter but narrower band widths shall be used for pipe up to 6 diameter and adifferent colour coding arrangement shall be used for pipe below 2 diameter and firefighting pipework of all sizes. The band width requirements for different pipe sizes andthe locations at which the bands require to be applied are detailed in Section 9.

6. Basic/PrimaryIdentification Band Colours

6.1. The Basic/Primary Identification Band (PIB) colour determines the basic type of fluid.

6.2. BS 1710 specifies blue as the PIB colour for air, green for water, brown for oils, ochrefor gases, purple for acids and alkalis, silver grey for steam, black for drainage systemsand red for fire fighting systems. These colour conventions have been adopted apartfrom that for steam pipework, which is generally insulated and fitted with silver colouredmetal cladding. Crimson red is therefore specified for this service. An additional basiccolour of orange has also been used for added treatment chemicals. The completelisting, with BS 4800 colour reference numbers, is as given in Table 1.

7. Safety/SecondaryIdentification Band Colours

7.1. BS1710 does not specify SIB colours for all fluids. It only provides limited details of aSIB System. There are so many possible fluid identification requirements for different

types of facility that it would in reality be impossible to specify SIB colours that wouldsatisfy all BS1710 user requirements. The User Authority is required to allocate aspecific SIB colour, to provide the unique CCIB for each fluid in the facility.

7.2. It has therefore been necessary to allocate a specific SIB colour for each individual fluidwithin a fluid type or PIB, so as to provide a unique Colour Code Identification Band(CCIB) combination for that fluid.

7.3. The complete Colour Code Identification Listing, as allocated to date, is detailed inTable 3 but the system is sufficiently flexible that further SIB colours can be added toeach PIB colour as necessary, to enable additional fluids to be identified in future.

8. Pipework ColourCoding Identification Arrangement

8.1. The pipework shall be painted in accordance with the relevant paint Schedule of QP-SPC-L-002 for the appropriate service temperature conditions, environment andconstruction material.

8.2. Pipework 2" diameter and larger, other than Fire Fighting System pipework, shall bepainted a decorative colour of Light Grey or White along its entire length and providedwith the Colour Code Identification Bands (CCIB), as required for the relevant fluid.

8.3. The width requirements for the PIBs and SIB shall be the same for all pipe sizes over

6 diameter, with narrower band widths being used for pipe sizes varying from 2 to 6diameter. The dimensions shall be as follows.

Pipe Diameter Each Basic/Primary Band Safety/Secondary Band

2 to 6 inclusive 75 mm 50 mmGreater than 6 150 mm 100 mm

Hence, for pipe greater than 6 diameter in size, the total width of the CCIB shall be 150mm + 100 mm + 150 mm or 400mm. For 2 to 6 diameter pipe, it shall be 75mm +50mm + 75mm or 200mm.

8.4. From Table 3 it can be seen that some products are allocated the same colour for boththe PIBs and the SIB. In cases where the PIBs and SIB are the same colour, thepipework shall be painted with a single colour band of the full CCIB width, i.e. 400mmwide for pipework over 6 diameter and 200mm wide for 2 to 6 diameter pipework.

8.5. Pipework below 2 diameter in size, and Fire Fighting System pipework of all sizes,shall be finished in the decorative colour corresponding to the PIB listed in Table 1along its entire length. For specific fluid identification in such pipework, only a 100mmwide band of the appropriate SIB shall be applied as required.

8.6. Colour Coding Bands shall be provided on both sides of and adjacent to valves, tees,important fittings, wall entries, road crossings and overpasses and outboard of flanges

to and from equipment such as vessels, tanks, exchangers, compressors and pumps.


7/16

Page 7 of 16

8.7. Colour coding bands shall be provided at uniform intervals, not less than 30m and notmore than50m depending on the complexity and pipe run lengths, along horizontal andup vertical sections of pipework and at all feed points. Where multiple lines run close toeach other, such as in common pipe racks, the CCIBs (and line numbers and flowdirection) shall be located directly in line with one another at positions that are readily

visible.

9. Valves and Valve Access Manhole Covers

9.1. For Valves, the full valve body shall be painted with the SIB for the relevant fluid group.The full CCIB requires to be applied both sides of the valve, to the adjacent pipework,as detailed in Section 8.

9.2. For Control Valves, the valve bonnet and actuator or handwheel/lever, shall be painted

with one of the following two colours, to indicate whether the Control Valve is designedto fail open or fail closed.

Fail Open Control Valves shall be painted Green, BS 4800 Ref. No. 14-E-53.Fail Closed Control Valves shall be painted Red, BS 4800 Ref. No. 04-E-53.

The arrangement is shown in Figure 2.

9.3. Valve access manhole covers and their surrounds shall be colour coded, to identify thefluid in the pipework to which they provide access. The colour coding arrangement forthese components shall be as follows. A 100 mm wide PIB of the appropriate colourshall be painted around the periphery of the topside surface of the manhole cover, with

a 75mm wide SIB of the relevant colour for the fluid immediately inside and adjacent tothe PIB. For those fluids which have the same PIB and SIB colours, a 175mm wideband in the PIB colour shall be painted around the periphery of the cover. The topsideof the access chamber cover slab immediately surrounding the cover shall generally bepainted with a 250mm wide band of equi-spaced diagonal safety yellow 08-E-51 andblack stripes 00-E-53, which are the specified colours for Moveable Safety Hazards inTable 2.

9.4.Arrows in the PIB on the manhole cover shall be provided to indicate the flow directionthrough the pipework and the inlet and outlet locations.

The arrangement is shown in Figures 3.

10. Content Labelling and Safety Warning Signs

10.1. The additional use of Coloured Labels giving the full or abbreviated productdescription, temperature, pressure, and other details necessary to identify any potentialhazard, together with the appropriate visual aids and hazard pictorial symbols, is to beencouraged. Such labels and markings shall not, however, be considered as asubstitute for the CCIB, whose application is considered mandatory.

10.2. The use and extent of such labelling shall be at the Users discretion. They would be

beneficial in providing more detailed identification of, and differentiation between, similarproducts, such as different grades of Lube Oil.

10.3. Where applied, labels shall be brief and informative and written in English. The textsize for different pipe diameters shall be as specified in Section 12.


8/16

Page 8 of 16

10.4. The background colour of the label shall be similar to that of the appropriate PIB,ideally with appropriate SIB contrasting text colour, as shown in Table 1.

10.5. The length of the labels shall vary from 200 to 800mm and they shall be appliedadjacent to the CCIB locations.

The arrangement is shown in Figure 1.

10.6. International Safety Signs, as specified in BS 5499 Part 5, shall be used as necessary,to highlight and warn of potential safety hazards.

10.7. It is recommended that labels are painted directly onto the pipe surface using theappropriate specified paint rather than being applied in the form of self-adhesive plasticlabels. Plastic labels tend to deteriorate rapidly in strong sunlight and the harsh localenvironment and localized corrosion can occur beneath them.

11. Line Numbering

11.1. In addition to being Colour Coded, each pipe system, pipeline and valve shall beindividually identified by marking them in accordance with the QP EquipmentIdentification and Tag Numbering System, which is detailed in QP EngineeringStandard ES.0.07.0025. The required identification markings relate to pipe size, service,design, area code and ownership code. All characters used shall be in upper case. Noseparators, hyphens, punctuation marks or spaces are allowed.

11.2. The line number and the flow direction shall be stencilled on each pipe section andpipeline together with the CCIB, to provide the pipework with unique traceability. Theidentification markings shall be stencilled on the pipe a distance of approximately 400

mm from the edge of the outer colour band. Letter size shall be equal to half of the pipediameter for pipe between 2 and 12 diameter, with a minimum height of 1 for smallerpipe sizes and a maximum height of 6 for larger pipe sizes.

11.3. Line identification markings shall be stenciled in black directly onto the light grey/whitedecorative background.

11.4. Lines owned by other companies shall be assigned an ownership code by QP/RLC.

12. Size of Lettering and Direction Arrow

12.1. Size of lettering shall be as follows:

Pipe Diameter Width x Height Spacing

2 to 6 inclusive 30 x 30mm 10 mm min.6 to 50 inclusive 80 x 80mm 25 mm min.Greater than 50 100 x 100mm 30 mm min.

12.2. Shape and size of direction arrow shall be as follows:

Pipe Diameter W1 W2 L1 L2

(mm) (mm) (mm) (mm)

2 to 6 inclusive 10 30 45 1356 to 50 inclusive 40 80 90 270Greater than 50 50 100 150 450

13. Paint Specification

13.1. The areas of the painted surfaces to which the colour coding bands, lineidentification numbers and flow direction arrows are to be applied shall be degreased,water washed and lightly abraded, in order to ensure good adhesion of the applied paintto the existing topcoat paint. The relevant surface preparation requirements of QP-SPC-L-002 shall apply.

13.2. The colour coding band and marking paint used shall be an approved two-packhigh-gloss polyurethane paint product. The bands and markings may be applied in asingle coat, although more than one coat may be required to achieve the requiredobliteration of the preceding paint colour. If the colour coding bands are to be appliedover aged topcoat paint, it may be necessary to apply a coat of a compatible undercoat

paint of a slightly contrasting colour prior to the required topcoat paint.

14. GeneralProtection of Pipelines

14.1. Approved safety colour coded Corrugated Beam Barriers, Tension CrashBarriers (TCBs) or Concrete Vehicle Barrier Units (VBUs) shall be used to protect allpipeline routes.
