Other technical publications

The provision of technical support and guidance for gas professionals is one of the main reasons for our existence. In addition to our own suite of technical standards we have teamed up with the Energy Institute to offer a broader range of technical publications. 


Energy Institute Publications
A risk-based approach to hazardous area classification

This report presents an approach applicable to the classification of upstream and downstream petroleum facilities by consideration of the individual point source procedure.

Electrical installation of facilities for the storage and dispensing of LPG and CNG automotive fuels at vehicle refuelling stations

This guidance document is intended to assist those in the UK comply with the statutory Electricity at Work Regulations (1989) and petroleum storage legislation, with regard to electrical design and installation regarding to the storage and dispensing of LPG and/or CNG as an automotive fuel. The guidance includes key features of the electrical provisions of APEA/IP Guidance for the design, construction, modification and maintenance of petrol filling stations. The guidance in this publication has primarily been prepared for use within the UK. However, those installing such facilities elsewhere may benefit from considering the guidance included. ISBN 978-0-85293-410-4 Nov 2003.

Model Code of Safe Practice for the Petroleum Industry Part 1 - Electrical Safety Code

This title is essential reading for designers, managers, engineers and consultants responsible for the design and specification of safe electrical equipment for petroleum, petrochemical and similar installations handling flammable fluids. The Code provides an overview of the particular issues related to the safe use of electrical equipment in the petroleum industry, specifically in areas where there is a possibility of occurrence of a flammable atmosphere. Guidance is given on the selection of equipment together with installation, inspection and maintenance practices. Where more detailed guidance on specific topics exists, the relevant references are provided. This Code is applicable to both onshore and offshore areas, and is closely associated with IP Model Code of Safe Practice Part 15 Area classification code for installations handling flammable fluids. ISBN 978-0-85293-225-4

Model Code of Safe Practice Part 15 - Area Classification Code for Installations Handling Flammable Fluids Edition 4

Updates from the 3rd edition include:

  • Further details on Hazard Radii from liquid pool spills

  • Hazard Radii for some LNG releases

  • More detail on the risk based approach methodology and emphasis on the point source approach

  • Revised equivalent hole sizes for frequency bands (LEVEL I - III) and expanded guidance on ventilation and releases within enclosed areas, based on evidential data from the UK HSE.

  • Amended, or more detailed, definitions of terms such as adequate ventilation, grades of release and limits of applicability.

The revised information provided in EI15 may therefore lead to a reduction in the size of some zone areas, enabling potential cost savings to operators and contractors. Whilst EI15 provides guidance on applying a risk based approach for specifying hazardous areas, the full methodology is outlined in a separate publication; A risk-based approach to hazardous area classification (2nd edition due end 2015). ISBN 97808 52937174

Model Code of Safe Practice Part 19 - Fire precautions at petroleum refineries and bulk storage installations 3rd Edition

Essential reading for process safety engineers, safety advisors, designers, emergency planners or others with responsibility for fire and explosion hazard management to meet the pertinent requirements of the European Seveso II Directive, whether sites are classified lower or upper tier. The new edition of this important publication provides guidance on selecting, implementing and monitoring the continuing performance of site-specific justified risk reduction measures – from prevention through detection, protection systems to mitigation measures – to reduce the risk from design event fires at installations that process and store petroleum, intermediates and refined products.

Safety advice for emergency services attending gas escapes

Emergency services are called upon to attend a variety of incidents involving gas mains, services and other apparatus. The Safety advice for emergency services attending gas escapes leaflet is intended to provide clear advice on the measures to be adopted in dealing with gas escape incidents and to ensure site safety specifically in relation to: 

  • Actions required by emergency services prior to gas personnel arriving on site
  • Actions required by emergency services following gas personnel arrival on site.
