7.11.1 The lighting system shall be split into three main systems: a. Normal system: fed from normal distribution boards.
b. Emergency system: fed from emergency distribution boards comprising of, a minimum of 30 % of the total normal lighting in any area, a higher percentage of emergency fed lighting shall be supplied in area’s where black start activities have to be executed such as control rooms, switchgear rooms and generator rooms to allow safe and adequate operations. In the emergency generator/ switchgear room and UPS battery and equipment rooms all lighting fixtures shall be fed from the emergency switchboard and provided with integral battery back-up suitable for use in Hazardous area’s (Zone 1, minimum: IIB, T3, battery rooms IIC T6 or T4). Lighting in access door air locks shall be emergency type with battery back up.
c. Emergency system, battery backed-up: Exit lights and selected luminaries, which illuminate escape routes, exits and ladders, shall have an integrated Ni- Cd battery and shall be suitable for use in Hazardous area’s (Zone 1, minimum: IIB, T3). As a minimum 30 % of the total emergency lighting in any area shall be battery backed-up.

7.11.2 Lighting system designed for the plant facilities shall include plant lighting, building lighting, sub stations, street and area lighting, plant perimeter fence lighting, etc. Lighting system shall provide uniform and adequate intensity of light in working areas and shall be arranged to give a symmetrical appearance. All outdoor lighting fixtures shall be suitable and certified for the maximum ambient temperature as stated in section 1.11. Luminaries shall be as per IEC 60598.
7.11.3 The use of high-pressure sodium vapor lamps (HPS) shall be maximized as far as possible for illumination at operating platforms, below pipe racks, etc. throughout the plant. However, lighting fittings in strategic locations and for emergency lighting shall be fluorescent type. For offshore, high pressure sodium floodlights shall be used for boat landing and work over areas lighting.
7.11.4 Illumination levels shall be in accordance with the levels as stated in Appendix-A. Calculation methods and design approach shall be in accordance withthe IESNA (Illuminating Engineering Society of North America), reference standard
ANSI/IESNA RP-7-01. In case any specifics are not covered by the IESNA standard, API RP 540 (Electrical Installation in Petroleum Processing Plants) can be applied as guidance.
7.11.5 No outdoor lighting switch shall be provided on an offshore platform unless otherwise specified.
7.11.6 Lighting ingress protection in outside area shall as a minimum be IP56.
7.11.7 Industrial/decorative fluorescent lighting fixtures with electronic ballasts shall be used for illumination in substations, control rooms, offices, etc. Lighting installation in control rooms and conference rooms shall be designed for switching off independently ceiling light groups to suit operator needs. Dimmers shall be provided to control the illumination level. Special attention shall be paid to the lighting in control rooms to ensure that screen operation is not impaired by light reflections. The reflectors on the luminaries shall be such as to provide glare free light with high degree of visual comfort on the screens.
7.11.8 All lighting fittings in process areas shall be solidly fixed and not suspended by means of chains/conduits, etc. unless approved for specific applications. They shall be mounted such that routine maintenance can be carried out safely and without the use of temporary scaffolding.
7.11.9 Light fittings for general illumination shall be located as close as possible to instruments, gauges etc. as to avoid special lighting for these devices.

7.11.10 Flood lights shall be used for open area lighting. Flood lighting fixtures shall be mounted at sufficient elevation and directed so as to provide uniform illumination. Plant structures shall be used where possible for mounting such flood lights. Street lighting and flood lighting poles shall be of suitable type to facilitate re-lamping and where these are to be installed in existing facilities, they shall match with existing arrangements and subject to ADMA-OPCO approval.
7.11.11 Onshore all outdoor plant lighting, street lighting, fence lighting and flood lighting shall be controlled by photo electric cells.
7.11.12 For all street lighting, fence lighting and flood lighting, high pressure sodium vapour lamps shall be used unless specified or approved otherwise (such as in case it has to match with existing facilities).
7.11.13 Lighting/receptacle distribution Panels shall be located in the area being served. All outgoing circuits in Panels located in plant area shall be controlled by double pole miniature circuit breakers. At least 20 % spare outlets shall be provided in each lighting and receptacle distribution panels.
7.11.14 Aircraft warning lights shall be installed on all structures 40 m and above, designed and constructed in accordance with local aviation regulations. Lamps used for aircraft warning lights shall be of neon tube and long life type. Lighting fixtures used on stacks shall be able to withstand the expected vicinity temperature of the installation.
7.11.15 Tank farm Lighting shall be by flood lighting. However flood lighting poles/towers shall be located outside the tank bunds.
7.11.16 All junction boxes used for lighting and receptacle circuits in the plant areas shall be of high impact, flame retardant, ultra violet resistant glass reinforced polyester. 7.11.17 Minimum size of wiring for lighting and receptacle circuits shall be 2.5 mm² and 4
mm² respectively. All wiring for lighting and receptacle circuits in all (industrial as well as non industrial) buildings shall be concealed using PVC conduits.
7.11.18 A maximum of 12 lighting fixtures per lighting loop shall be applied. The arrangement shall be such that failure of one lighting loop will not result in complete darkness of one area. Therefore as a minimum two lighting loops per area shall be applied.
7.11.19 Helideck lighting and associated illuminated wind sock shall be as per local aviation authority requirements.
7.11.20 Navigational aids for offshore installations shall be provided in accordance with the local coastal protection acts.
7.11.21 For onshore airport, lighting requirements (air stripers) shall be provided as per local civil aviation authority requirements.
