Website: www.oisd.gov.in Tele: 0120-2593800, Fax: 0120-2593802 Government of India Ministry of Petroleum & Natural Gas Sr.Number:- OISD/2012/001 Page No. II Preamble Indian petroleum industry is the energy lifeline of the nation and its continuous performance is essential for sovereignty and prosperity of the country. As the industry essentially deals with inherently inflammable substances throughout its value chain – upstream, midstream and downstream – Safety is of paramount importance to this industry as only safe performance at all times can ensure optimum ROI of these national assets and resources including sustainability. While statutory organizations were in place all along to oversee safety aspects of Indian petroleum industry, Oil Industry Safety Directorate (OISD) was set up in 1986 Ministry of Petroleum and Natural Gas, Government of India as a knowledge centre for formulation of constantly updated world-scale standards for design, layout and operation of various equipment, facility and activities involved in this industry. Moreover, OISD was also given responsibility of monitoring implementation status of these standards through safety audits. In more than 25 years of its existence, OISD has developed a rigorous, multi-layer, iterative and participative process of development of standards – starting with research by in-house experts and iterating through seeking & validating inputs from all stake-holders – operators, designers, national level knowledge authorities and public at large – with a feedback loop of constant updation based on ground level experience obtained through audits, incident analysis and environment scanning. The participative process followed in standard formulation has resulted in excellent level of compliance by the industry culminating in a safer environment in the industry. OISD – except in the Upstream Petroleum Sector – is still a regulatory (and not a statutory) body but that has not affected implementation of the OISD standards. It also goes to prove the old adage that selfregulation is the best regulation. The quality and relevance of OISD standards had been further endorsed by their adoption in various statutory rules of the land. Petroleum industry in India is significantly globalized at present in terms of technology content requiring its operation to keep pace with the relevant world scale standards & practices. This matches the OISD philosophy of continuous improvement keeping pace with the global developments in its target environment. To this end, OISD keeps track of changes through participation as member in large number of International and national level Knowledge Organizations – both in the field of standard development and implementation & monitoring in addition to updation of internal knowledge base through continuous research and application surveillance, thereby ensuring that this OISD Standard, along with all other extant ones, remains relevant, updated and effective on a real time basis in the applicable areas. Together we strive to achieve NIL incidents in the entire Hydrocarbon Value Chain. This, besides other issues, calls for total engagement from all levels of the stake holder organizations, which we, at OISD, fervently look forward to. Jai Hind!!! Executive Director Oil Industry Safety Directorate Sr.Number:- OISD/2012/001 Page No. III Foreword Petroleum Depots, Terminals, Installations; Pipeline Installations; Lube Oil Installations are intermediate processing, storage & transportation points and are vital components of the downstream logistic value chain of the petroleum industry. These play a pivotal role in ensuring seamless movement of product from Refineries to the points-of-sale in the consumption centres. In a vast country like India, with its widespread petroleum product distribution network, continuous safe operation of these units is a national imperative. For the logistic management purpose, population of these units are large and all of them are located not too far off from human population indicating thereby the high risk perception associated with substantial bulk storage of inflammable petroleum products in such locations. The locations themselves experience heavy footfall of business associates increasing the safety system demands. It is, therefore, essential to develop a standard for fire protection facilities for such locations which would ensure adequacy in terms of its ability to contain any incident from developing into a catastrophe while achieving optimality in terms of life cycle cost of installation, operation and maintenance. This standard was first released in 1989. Subsequently, with the advent of widespread automation in these types of locations and quantitative increase in storage capacities to satisfy the growth in demand, subsequent revision was issued in Aug 2007. Further amendments to the same were issued in July 2008 and last in October 2010 which emanated out of the in-depth analysis of the recent major fire incident by an expert committee. This amendment, issued now in July 2012, incorporates the duly optimized recommendations, over and above the October 2010 amendment, emanating out of the in-depth analysis by a series of high power committees constituted in this context in addition to the inputs from the Safety Council of OISD to bring in further clarity after weeding out ambiguities. In this amendment, substantive additions had been made in critical firefighting and mitigating systems after optimizing the same. Attempts had also been made to align the standard to international codes of design, practice and certification. We, at OISD, are confident that the provisions of this standard, when implemented in totality, would go a long way in ensuring safe operation of the target group of locations. Needless to mention, this standard, as always would be reviewed periodically based on field level experience, incident analysis and environment scanning. Suggestions from all stake holders are fervently solicited. OISD hereby expressly disclaims any liability or responsibility for loss or damage resulting from their use. .Number:.Page No.OISD/2012/001 NOTE OISD publications are prepared for use in the oil and gas industry under Ministry of Petroleum & Natural Gas.
