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

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

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

14. 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,

15. 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

16. 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

17. 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

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

35. On-site Risk • Off-site Risk

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

37. Part two • Preparedness, Planning, Response

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

40. 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

41. Good practices • Technical approaches

42. Management review

44. Transport Sector

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