  2. 2. Terminal Process Safety Expectations & Standards Government policies & regulations, mandate all operators of MHF must do everything possible to reduce risk to “as low as reasonably practical” (ALARP) . . . . MHF – Major Hazards Facility (OH&S Act 2007)

  5. 5. Loss of product containment Explosion • 40 minutes undetected • 300 tonnes of petrol released • Ignition source Impacts of the Disaster (Potential at other sites) • Explosion in one tank spreads to 20 others. • Blast wave damaged structures up to 8 km away. • Fire burnt for 3 days. • 25 fire engines, 20 support vehicles and 180 fire fighters • 43 reported injuries. • Schools, transport were disrupted • 92 businesses employing 9,500 people displaced • 410 redundancies & 923 casual jobs lost. • Extreme environmental impact from use of fire fighting chemicals on soil & water bodies. • £1 Billion including £750 M pay-up in claims.

  6. 6. Immediate Causes • Failure of primary containment due to inoperability and/or malfunction of the automatic tank gauging system (ATGS) and the independent high-level switch (IHLS) • Insufficiently designed secondary (Bunds) and non-existent tertiary containment Wider Underlying Causes • Buncefield operators had little control over the two remotely operated UKOP pipelines • Inadequate shift handover Terminal Process Safety Buncefield Disaster – Causes

  8. 8. Terminal Process Safety ALARP – Where do you want to be? How to achieve? Recommendation 3 – Prevention Layer Operators of Buncefield-type sites should protect against loss of containment of petrol and other highly flammable liquids by fitting a high integrity, automatic operating overfill prevention system (or a number of such systems, as appropriate) that is physically and electrically separate and independent from the tank gauging system. •Such systems should meet the requirements of Part 1 of IEC 61511 for the required safety integrity level.
  9. 9. Terminal Process Safety ALARP – Where do you want to be? How to achieve? Recommendation 13 – Mitigation Layer Operators of Buncefield-type sites should employ measures to detect hazardous conditions arising from loss of primary containment, including the presence of high levels of flammable vapors in secondary containment. Detecting high levels of vapor in secondary containment is an early indication of loss of containment and so should initiate action, for example through the overfill prevention system, to limit the extent of any further loss. Installing CCTV equipment that detects and responds to changes in conditions and alerts operators to these changes.
