VULNERABILITY ANALYSIS

1
VULNERABILITY ANALYSIS

• This systematic process of evaluating the
  probability and potential impact of each
  emergency.
• Use a numerical system to
• Assign probabilities
• estimate impact
• assess resources
• The Higher The Score the Better

2
VULNERABILITY ANALYSIS

• List Potential Emergencies
• Include internal and external emergencies
• Factors to consider
• historical
• geographic
• technological
• human error
• physical
• regulatory

3
VULNERABILITY ANALYSIS

• Historical Factors, what HAS occured
• at this facility
• at similar facilities
• at other facilities in the area
• in the community at-large
• Geographical Factors (ie. due to location)
• flood plains, seismic faults
• adjacent company hazards
• airports, railroads, highways, nuclear power

4
VULNERABILITY ANALYSIS

• Technological Factors
• Process Safety
• Computer Failure
• Power Failure
• Emergencies from human error due to
• poor training
• misconduct
• fatigue
• drugs/alcohol

5
VULNERABILITY ANALYSIS

• Physical Factors
• layout of equipment
• proximity of shelter areas
• physical construction
• Regulatory Factors
• Limited by regulations?
• Required to respond by regulations?

6
VULNERABILITY ANALYSIS

• Estimate Probability
• Rate the likelihood of emergency
• Use scale of 1 to 5 (1 lowest probability)
• Subjective consideration
• Be consistent

7
VULNERABILITY ANALYSIS

• Estimate the Potential Human Impacts
• the possibility of death or serious injury
• Estimate the Potential Property Impacts
• cost to repair/replace
• cost of temporary facilities
• Estimate the Potential Business Impacts
• business interruption
• breach of supply contracts
• inaccessiblity by employees, customers, shippers

8
VULNERABILITY ANALYSIS

• Assess Internal and External Resources
• The lower the score the better
• in-house assets/talents sufficient
• responsiveness of external support
• Add the columns
• The lower the score the better
• Subjective, but comparisons provide planning and
  resource priorities.

VULNERABILITY ANALYSIS

• Sounds easy, Right???
• Lets do one on a simple emergency.
