COLOUR IDENTIFICATION OF PIPEWORK AND SERVICES All known pipework conveying fluids in liquid and/or gaseous states are covered by this Manual. Pipelines in services which are not covered by this scheme and required to be Colour identified shall be referred to the authorized ADMA-OPCO group to advise appropriate Colour identification. 14.1 14.1.1 Colour Identification Scheme Philosophy As there are a limited number of Colours readily distinguishable under all conditions of lighting and aging. This Manual has considered an identification scheme which consists of more than one Colour in defining any particular service.

14.1.2 Commodity having properties in common are grouped under one basic Colour, e.g. oil, water, gas, chemicals refer to tables below: Basic Identification Colours and Group of Fluids Group of Fluid Steam Water Crude Oil Petroleum Gases Kerosine, Diesel Oil, Jet Fuel etc. Instrument and Industrial Air, Nitrogen, Oxygen, Halon & Vacuum Chemicals Acid and Alkali Fire Protection Vents, Drains & Slops Colour Silver Grey Green Brown Yellow Ochre Black Light Blue Orange Violet Red Light green Colour Coding as per BS 4800 10 A 03 12 D 45 06 C 39 08 C 35 00 E 53 20 E 51 06 E 51 22 D 43 04 E 53 12E53

14.1.3 Individual characteristics of different services within the common group are distinguished by a secondary Colour. 14.1.4 Any pipework originally painted (background Colour coded) along its entire length with one of the basic Colours, an aluminum contrast band shall be used as an additional outer most Colour to distinguish between the decorative Colour and the basic Colour identification of this particular pipework. 14.2 Application of the Pipeline Identification Colours

14.2.1 Colour Identification Band Lay-out The Colour identifying all pipeline contents within ADMA-OPCO facilities are listed in Appendix-B. The Colour coding shall consist of three bands, the outside Colour bands shall be the basic identification Colour for a particular family of commodity, and the central band shall represent the secondary Colour allocated for characterizing further the type of fluid within this major family or group (See Appendix-C Fig. 1) 14.2.2 Contrasting Bands The protective or background Colour code of the pipe shall not account for the basic identification Colours. If the decorative Colour interacts with the basic Colour, a strip of aluminum band (50 mm) wide shall be applied at the outer edges of the basic Colours (See Appendix- C Fig. 2). 14.2.3 Surface Preparation Prior to the application of Colour identification bands, directional flow arrows, contrasting band and line numbers, all surfaces must be degreased, detergent washed with 5% biprox or equivalent, high pressure fresh water washed and allowed to dry. Section 6 of this Manual shall be followed to satisfy the preliminary work requirements. It may be necessary to slightly abrade the surface using fire emery paper prior to the application of the identification Colours.
