Industrial risk: main issues

• Industrial risk main issues

A relevant problem of planning is that everything
has to be done so quickly . My experience is
that the overall time of design and
implementation is shorter if there is enough time
to think to the entire project (M. Andersson,
Swedish Railway Adm.)

• Safety management and policy in the firm
• Control over land uses
• Right to be informed
• External emergency plan

Classification of plants
Plants subject to safety report Plants
subject to notification only

Difference between probabilistic risk analysis
and scenario approach

• Probabilistic risk
• analysis
• R H VE
• Scenarios
• choosing a specific
• event and its characteristics

Vulnerabity
Hazard

Risk

P1 P2 P3 A way to bring scenario
approaches closer to probabilistic risk
assessment (PRA)
12
Hazard analysis - probability of each
scenario - Analysis of types of failures in
the plant - Chain of failures
13

• Vulnerability assessment
• Other plants (domino effects)
• lifelines (domino effects)
• transportation networks

14

• Vulnerability assessment
• - Public buildings
• - Dwellings
• - Population

15
Differences between Seveso I and II

• Seveso I
• Need to make hazardous installations safer
  (inspection, technical devices)
• Internal emergency plan
• Citizens right to know

• Seveso II Seveso 1
• Safety policy in the plant
• Focus from inside to outside
• Domino effects
• Land use planning
• External emergencyplants
