DIP Unit A 4th Edition - Element A2 - v Slide 9 DIP Unit A 4th Edition - Element A2 - v Slide 10 Difference between a near miss and a fatal accident in terms of time and distance can be very small The damage to persons or property is not the accident, but part of the effects of the accidents (i.e. the result or consequences). An old adage says never waste an accident Every accident constitutes an opportunity to correct some problem A near miss which has the potential to cause loss is just as important as a serious injury/damage HSG245 Investigating accidents and incidents An adverse event includes accidents and incidents The term adverse event, as used by the HSE is similar to the term accident and encompasses events that have a wide range of outcomes The HSE reserve the term accident for events that involve harm to people The HSE define an Accident as: An event that results in injury or ill-health DIP Unit A 4th Edition - Element A2 - v Slide 11 DIP Unit A 4th Edition - Element A2 - v Slide 12 Sample of PowerPoint presentation for NEBOSH Diploma in Occupational 2

3 Diploma - Unit A - Element A2 - March 2011 Some years ago, a study of 1,750,000 accidents, in 21 industry sectors, led by Frank Bird, showed that there is a fixed ratio between losses of different severity (and accidents where no loss occurred, i.e. near misses) This can be demonstrated with a pyramid model Accident ratio study Source: Frank Bird. DIP Unit A 4th Edition - Element A2 - v Slide 13 DIP Unit A 4th Edition - Element A2 - v Slide 14 Accident ratio pyramid Source: HSG96 the costs of accidents at work. Use If only those resulting in injury are considered, many opportunities to learn about what goes wrong are being missed If near misses are also studied they can provide more opportunities to learn and possibly prevent some of the events that result in injury The Bird model includes property damage in addition to near misses The models help to convince people of the value of reporting a wide range of events and show that there are usually more near misses than injury events DIP Unit A 4th Edition - Element A2 - v Slide 15 DIP Unit A 4th Edition - Element A2 - v Slide 16 Limitations Bird s findings are not uniform throughout industry The accident ratio studies may not necessarily show the extent of the loss to the organisation There are no universally agreed definitions of each subset of accident type Statistical analysis of loss events relies on large numbers, comparable work and worker skills over the measured timeframe, to be effective In smaller organisations, the first recorded accident may be the top event, i.e. fatality or major injury Near miss reporting may mean different things to different people HW Heinrich proposed one of the first coherent theories of in the mid 1920s Suggested that accidents were not acts of God but were caused by the failures of people His domino theory suggested that the series of events, which led to an injury or some other loss, were a succession of events which followed a logical pattern DIP Unit A 4th Edition - Element A2 - v Slide 17 DIP Unit A 4th Edition - Element A2 - v Slide 18 Sample of PowerPoint presentation for NEBOSH Diploma in Occupational 3

5 Diploma - Unit A - Element A2 - March 2011 Multiple accident causes Usually more than one causative factor Each of the multiple causation factors may be seen as one domino in its own line of dominoes (just as the roots of a tree branch out) Reason proposed four levels of human failure, each influencing the next The first level that Reason identifies is unsafe acts of persons, which ultimately lead to the accident These unsafe acts were considered to relate to the errors, such as the skill-based slips/lapses and mistakes identified in Rasmussen s work in called active failures Reason identified three further levels of human failure that comprised latent failures Source: RMS. DIP Unit A 4th Edition - Element A2 - v Slide 25 DIP Unit A 4th Edition - Element A2 - v Slide 26 The second level of human failure involves preconditions that lead to unsafe acts taking place In many instances, these preconditions can be traced back to instances of unsafe supervision, the third level of human failure identified by Reason Importantly, Reason s identified that causation did not stop at the supervisory level He recognised that the fourth level, the organisation itself, can impact on performance at all levels J.
