The Baker Panel Report - ABSA

ANNEX I—PROCESS INCIDENT INDEX EXAMPLESummaryThis example process incident index is provided to help BP understand the Panel’s expectations on the content of a lagging index that could beused to measure actual process safety performance and thereby quickly establish a lagging indicator that measures overall process safetyperformance. BP should evaluate this example and consider modifications as appropriate.The process incident index would be a lagging indicator that captures overall process safety performance through counts of fires, system overpressuresand explosions, chemical releases, and injuries/fatalities. The denominator for the index would use worker hours in the same manner as the OSHAinjury index.The process incident index would be calculated in a manner similar to the OSHA injury index. The annual number of process safety incidentcounts would be divided by the total hours worked in the facility and then multiplied by 200,000 in order to create a normalized annual index foreach 100 workers. (Since an employee works approximately 2,000 hours per year, 200,000 hours represents the approximate annual number ofhours that would be worked by 100 employees.)Example:Assume:(1) a plant has 200 employees, each of whom worked 2,000 hours in a calendar year; and(2) incidents with a total of five counts occurred in the plant that year.Calculation of the Process Incident Index:Step 1:Divide the five counts by 400,000 hours worked in the calendar year.Step 2:Multiply the count by 200,000, producing a Process Incident Index of 2.5 for the year.Process Incident Index Count Threshold—Definitions and ExamplesDefinition of “Fire”:Unintentional fires of any magnitude and unintentional electrical arcs.Set forth below are examples of items that add to the count total: a leak that results in a flame; a tangible indication of a fire (e.g., soot on the inside of distillation tower) where no flame was actually seen; a fire on a scaffold board in a process unit; a fire in a vehicle parked by an operating unit; a 120 volt shorted switch;Panel’s Recommendations C 258
