Occupational accidents – a holistic approach Daryl Attwood, PhD * Based on research conducted at Memorial University of Newfoundland, Canada
Safety notes • No alarm tests are expected, so any heard are real • Evacuation routes • Muster location
Lloyd’s Register • Celebrated 250th anniversary in 2010. • Lloyd’s coffee house – London – not the insurance company • Primary objective – safety of people in the industries we serve. • Began with ships – now in many industries, including a significant oil and gas presence.
Major accidents…. Explosions - Piper Alpha Helicopter crashes
Fatality causes Accidents usually defined as “Major Accidents” (air transport, explosion, burn): 24%. Other accidents: 76%
Occupational accident root causes……… Direct causes? Quality of safety equipment? Weather conditions? Safety behaviour? Organisational issues? Training? Procedures? Corporate safety culture? Lost time incident frequency (LTIF) ranged from 0.00 to 3.96 Something even broader? Cultural / Regional differences? Global Fatal Accident Rate (FAR) = 3.1 Middle East = 2.4, Africa, 4.4, South America 5.2 Financial pressure on corporations? FAR = Fatal accidents per 100 million hours workedLTIF = Fatalities + lost workday cases per one million hours worked
Regionaldifferences Africa, FSU greater than 5 Europe, Middle East, North and South America between 2.9 and 4. Asia, Australia less than 1.5
Safety experts polled as part of research to gather opinion with respect to the relative importance of many factors……some selected results….
Tosca receives a major injury Falls down the stairs Running Substance on the floor Not looking where she was going Interview During break No permssion Not aware of danger Lack of attention Not reported Not cleaned up Using mirror Unaware of danger Takes place in stores Taken at wrong time Lack of supervision Not told not to run Not trained. No informationNo supervision Using contractors machine No procedures No procedure Substandard induction. No refresher No employees to use contractors eqpt Review procedure for spillage Review induction cse and refresher training Review system for visitors Review break timings supervision increased Review timings supervision increased Refresher on safety standards/ procedures Review induction awareness training Review procedures for cleaning The existing approach to occupational accident analysis – Tosca’s fall fault tree But were there any broader causes? Financial pressures? Others? Corporate Issues Direct Causes
A holistic approach to occupational accident analysis External influence Corporate influence Direct factors

Model running mechanism • Calibration against an existing, known result. • Compare performance of case under consideration with base case for each element. • Re-run model using adjusted component reliabilities – this generates actual prediction for the case under consideration.
Safety situation – installation Factors judged less conducive to good safety than industry average Factors judged more conducive to good safety than industry average
Model Uses • Predict accident numbers or frequencies on new installations • Study the effect of changes in individual safety program elements on safety results • Establish key performance indicator targets for staff and contractor organisations.
