Types of Standards / Codes are Man Made & God Made Eg. Of God Made Laws Science and scientific actions Chemical reactions, Physics, Mathematics, Heat Radiation Effect wrt Burning rate, Wind effect, …etc • Fire Equation CH 4 + 2 O 2 = CO 2 + 2 H 2 O + HEAT In this session we shall cover Man Made Laws “framed” in the background of God Made Laws • •
Standards / Codes are of 2 Types Man Made & God Made • Eg. Of Man Made Laws • Person below age 18 should not be engaged in works related to hazardous industry … • Ladies should not be deployed in night shift. . • No exit door shall be less than 1 mtr width. . • Factories Act & Rules, Petroleum Act (OISD), which are directly related to our session on Standards & codes for POL Storage & Installations
God Made Laws - which form the basis for framing - Man Made Laws are · Flash Point of the product · Upper Explosive Limit & Lower Explosive Limit MS 1. 3 -7. 6, HSD 0. 7 -5 SKO/ATF 1. 3 -8, · Auto Ignition Temperature of MS-257, HSD-256, & ATF-255 · Heat Radiation Effect wrt wind effect, release of vapors · Unconfined Vapour cloud Explosion : · Release of flammable vapour in atmosphere, Mixing with air · Totally within flammable range or the outer layer is within flammable range with Delayed ignition · Flash Fire of UVCE depending on quantity and mixing with air · High pressure lasts only fraction of a second. · Persons may not get killed due to blast, but secondary effects cause death and destruction
Tank-Fire Clippings 25 seconds. Fire Spreading to Neighboring Tanks Even without Unconfined Vapour Cloud Explosion, since Inter Tank Distance is not maintained. Clipping goes to prove AUTO IGNITION effect which causes BLOW OUT – Explosion of CRVT Tank with Roof Flying away by failing in its weakest joint STITCH WELD at Curb Angle

Petroleum Rules Vs OISD • OISD derived power from Petroleum Rules but it Super Seeds Petroleum Rules. • All the inter distances mentioned in the above Petroleum rules is super Seeded by OISD 118 Revision Sep 2004, since Petroleum rules empowers OISD 118 as Part of it.
OISD 118 ( Revision-II Sep 2004 ) Layout for Oil & Gas Installations • Facilities to be laid in blocks with arrangement following the route of raw material, process and finished goods. • Layout to be divided into suitable blocks with roads all around. Roads separate the blocks acting as ‘fire breaks’. • Road to be designed for maneuvering of largest Fire Tender. • Two road approaches from highway/major road to be provided – one for employees and other for material movement. • Rail spur to be located close to periphery.
OISD 118 Information required for preparing Layout • Site topography including elevation, slope and drainage • Meteorological data • Seismic data • High flood level & high tide level • Aviation consideration risk from adjacent facilities • Statutory obligations • Environmental considerations
OISD 118 General consideration for preparation of Layout Tank farm, Filling sheds & ETP be located at high grounds. Control room in non-hazardous area. Power generation facilities near boundary walls. No over head lines to pass the installations. LT sub-stations located near the load centers'. Storage tanks to be grouped according to classification. TT loading/unloading close to the main gate with oneway traffic for entrance and exit. • Independent waste collection centers'/ETP • Smoking booths 60 meters away from Hydrocarbon source. • •
OISD 118 General consideration for preparation of Layout • Fire Fighting Facilities say at a safe place away from the hazardous area. • Fire water pumps and tanks as per OISD 116 (Refineries) 117 (POL) & 144 (LPG).
OISD 118 Layout of Storage Tanks wrt CRVT & FRVT & Dyke Capacity • In a single dyke, not more than 60, 000 kl if all tanks are CRVT. • In a single dyke, not more than 1, 20, 000 kl if all tanks are FRVT. • If both CRVT and FRVT are located together in a single dyke, the total capacity shall be restricted to 60, 000 kl. • Fixed cum floating roof tanks will be considered as CRVT. • Dyke minimum 1 mtr, max 2 mtr, walk way 0. 6 mtr and capacity largest tank inside the dyke. • Inter distance between two tanks located in two different dykes shall not be less than the diameter of largest tank or 30 meter whichever is more. • Process equipments, Pump stations & pipe manifold should not be located in dyke area.
OISD 118 Layout of Storage Tanks wrt Class A, Class B & Class C Class A & B can be stored in the same enclosure Class C preferably in separate dyke enclosure Excluded stored in separate dyke only However if Class C is stored along with A or B, conditions applicable to class A or B as the case is will be applicable • Tanks shall be arranged in Maximum of 2 rows so that each tank is approachable • Tanks having >50, 000 kl shall be arranged in single rows • •
OISD 118 Layout of Storage Tanks wrt FIRE WALLS, TANK DIMENSION • Fire walls minimum 0. 6 mtr height to prevent spill for 5 m one tank to another tank in the same enclosure. For excluded products, height of the dyke wall will be minimum 0. 3 m • Tanks with dia not > 9 meter and total not > 5000 kl tank will be considered as single tank • Height of the tank not more than 1. 5 Dia or 20 metres, whichever is less. • Pipe from the tank shall run directly to outside of dyke with minimum possible distance (pipes originating from other dykes shall not pass through any other dyke). • Minimum distance between tank shell and dyke wall be not less than 0. 5 Height of the tank.
OISD 118 Layout of POL Storage Installations Inter-distance between facilities • For larger installations, Table 3 & 4, wherein total storage of class A and B is more than 5, 000 kl or dia of tank is more than 9 metres. • For smaller installations, table 5 shall be followed. • Table 5 also applicable for location storing only class C and excluded petroleum.
