  1. Chemical/Industrial Disaster Management Dr Rakesh Dubey Director Disaster Management Institute Bhopal rakeshddubey@hotmail.com

  2. BHOPAL

  3. Industrial Disaster Management Cycle: OECD 2004

  4. What to do? • How to do? • Is there any way exists?

  5. Disaster Management Planning both on-site and off-site with following components: A. Risk Assessment & Management B. Emergency Preparedness C. Community Dialogue

  6. Part one • Disaster Impact Assessment • Toxic release, heat fluxes, pressure waves

  7. Risk Assessment & Management 1. evaluate range of potential incidents (without considering possible causes) 2. put mitigation in place for foreseeable ones 3. evaluate community consequences for range of incidents,

  8. a) credibleworst case - largest tank or worst failure consequence - reasonable duration of release - passive mitigation in effect - credible worst weather b) worstimaginable case - largest tank or worst failure consequence - worst possible duration or release - no mitigation - worst possible weather

  9. Reliability Risk Assessment • Risk Based Maintenance Planning • Risk estimation • Hazard identification • Quantitative Hazard Assessment • Probabilistic Hazard Assessment • Risk Quantification • Risk evaluation • Setting up risk acceptance criteria • Risk comparison • Maintenance planning

  10. What may go wrong? What would be the impacts? Start How it may go wrong? How likely its occurrence? Hazard identification Probabilistic hazard assessment Quantitative hazard assessment Accident scenario development What maintenance schedule would reduce its likelihood of occurrence? Fault tree development Fault tree for the envisaged scenario Consequences analysis Fault tree analysis Apply maintenance measures and re-evaluate risk Risk estimation Suggest maintenance measures to control risk Whether risk is in acceptance? No Yes End

  11. Storage Conditions • Atmospheric Storage • Pressure Storage • Fully Refrigerated Storage • Semi-Refrigerated Storage • Gas Under Pressure Which condition is leading to significant impacts

  12. On-site Risk • Off-site Risk

  13. Hazards identification : Materials, process, regulatory, • Consequence of hazards • Likely hood of consequences • Frequency of occurrence • Calculation of Risk • Decision for weighing alternatives

  14. Part two • Preparedness, Planning, Response

  15. By putting prevention techniques • Through planning • By response plans • Through mitigation • Education and awareness • Best practices

  16. ALARP means ‘As Low As Reasonable Practicable’ ALARP demonstration means: To demonstrate that the project & associated systems and HSEMS will enable the facility to be operated & maintained safely such that residual risks to HSE are tolerable

  17. Good practices • Technical approaches

  18. Management review

  19. Transport Sector

  20. How plan should be made more use full for Top Management • Communication

  21. Living with the risks with continuous improvement: UN’s Statement of 2nd WCDR Kobe Japan
