Battery Fire Risk Score with thermal event severity score of 20 score: a worked example

Push thermal event severity score up to 20 score and the picture changes. This example computes every intermediate figure at that operating point. a recycler needs to rank fire risk for inbound lots, storage areas, disassembly work, sorting, or shredding operations

The inputs for this scenario

  • Thermal event severity score: 20 score (raised for this scenario; the documented default is 8)
  • Fire occurrence likelihood score: 6 score (unchanged)
  • Detection/control weakness score: 7 score (unchanged)

Working through the calculation

  • Applying the documented formula (Battery fire risk score = severity score × 40% + occurrence score × 35% + detection/control weakness score × 25%) to the inputs above produces each figure below.
  • At this operating point the engine returns 11.85 risk score for battery fire risk score, the number this scenario is built around.
  • At this operating point the engine returns 20 score for thermal event severity.
  • At this operating point the engine returns 6 score for fire occurrence likelihood.
  • At this operating point the engine returns 7 score for detection/control weakness.

How this compares with the baseline

  • Against the tool's baseline example, where thermal event severity score sits at 8 score and the headline result is 7.05 risk score, this scenario comes in 68.09% above the baseline at 11.85 risk score.
  • It computes a weighted composite fire risk score from severity (40%), occurrence likelihood (35%), and detection/control weakness (25%) on one shared 0-10 scale. The value of this scenario is the size of the gap it exposes: that gap, priced out over a year, is the budget you can justify spending to close it.

Results at a glance

  • Battery fire risk score: 11.85 risk score (headline result)
  • Thermal event severity: 20 score
  • Fire occurrence likelihood: 6 score
  • Detection/control weakness: 7 score
