9. What to do?
How to do?
Is there any way exists?

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

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

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

13. 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

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

29. On-site Risk
Off-site Risk

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

34. ALARP

35. 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
