Likelihood of Failure
Risk Matrix Exercise
11
• Likelihood of Failure• ???• ???• ???
• Consequence of Failure• ???• ???• ???
Risk Matrix Exercise
12
• Age• Material• Velocity• Depth• Past Work Orders
What Do You Think?
Likelihood of Failure
13
• Public Spaces• High Traffic Areas• Medical / School Facilities• Customers Impacted• Adjacent Infrastructure• Environmental Impact• High Visibility
What Do You Think?
Consequence of Failure
14
• Likelihood of Failure - Age• <10 =0• 10-30 = 1• 30-50 = 2• 50-70 = 4• 70 > = 6
• Likelihood of Failure - Material• ACP = 1.5• CIP = 2• DIP = 1• PVC = 0.5
• Likelihood of Failure – Past Work Orders• 0-5 WO = 1• 5 - > = 2
Risk Matrix ExerciseMax Score of 10
15
• Consequence of Failure - Customers Impacted• <10 = 0• 10-30 = 1• 30-100 = 2• 100-1,000 = 4• 1,000 > = 6
• Consequence of Failure – Environmental• Private Property = 0.5• Adjacent Stream = 1• Wetland = 1• Endangered Species = 1
• Consequence of Failure – Medical / School Facilities• Yes = 1• No = 0
