DMP analysis of serious injury data

Transcription

1 DMP analysis of serious injury data July to December 2013 AusIMM Perth Branch Technical Meeting 10 August 2015 Colin Boothroyd & Alan Holmes

2 Project scope Compare SRS injury data to fatality review Start with six months July to December 2013 Compare to historical data Develop better understanding of safety hazard profile Identify critical tasks and activities

3 Fatal Accidents 2000 to reports Falls from height OEM procedures - fitters in workshops Run away vehicles Vehicles over edges Vehicle collisions Electrical contacts Underground rock falls Open pit wall failures Inrush situations Tyre handling pressure and gravity Note: Additional 9 fatalities

4 SRS Data Mines Safety and Inspection Act Injury data 580 report manager Occurrence data 510 report manager Consistent standard of quality assurance 2002 Coding standards applied to data inputs Over 800 injuries in a six month period Includes over 600 serious injuries MSIA definition Over 1000 occurrences with no injury in six months

5 Serious lost time and restricted work injuries No. Serious LTIs No. Serious RWIs

6 Serious injuries per million hours worked 8 Serious reportable injury frequency rate Serious injuries per million hours worked

7 Conventional 2D charts (grouped categories) Service Staff 43 Underground Operators 58 Trades 53 Occupation Category Professional and Technical Process Workers Surface Operators OH&S Managers/ Supervisors Fitters Electrical Workers 20 Surface Drivers 70 Drillers and Blasters Number of serious injuries Serious injuries by occupation category

8 3D Pinnacle chart Without sprain injuries Fractures-Breaks Laceration Crushing Bruise/Contusion Dislocation/ Displacements Foreign body/ bites/punctures/splinters Amputation Chemical Effects Burns-Thermal Burns-Electric Arc/Flash Loss Of Consciousness Multiple Injuries Selected serious injury groups by activity (removing sprains and strains)

9 Accident triangle July to Dec 2013 actuals (total notifiable incidents 1873) 3 Fatal 181 HS 106 I LS 75 High level injuries 653 Other injuries 1036 Occurrences - No injury

10 Accident triangle Serious injuries - actual

11 High Severity (HS) serious injuries Activity (grouped) Amputation, fracture, crush injury Falls and slips on level surface 17 Falls and slips on elevated location 12 Hand Tools - manual and power 12 Suspended or dropped load/item 16 Crushed or caught between/against 26 Machinery and equipment 9 Lifting by hand or exertion 8 Hoses or vessels under pressure 2 Vehicle collisions 2 Electrical 1 Tyres 1 106

12 Normalised annual injury rate/1000 FTE employees High Severity (HS) Total Serious MSIA Total Reported Injuries

13 Accident triangle Jan to Dec 2014 actuals (as at 13/4/ notifiable incidents 3236) 3 Fatals HS 131 LS High level injuries 1008 Low level injuries 1881 Occurrences & incidents - No injury

14 Critical activities and hazards Total industry Falls from height Employee under suspended load or object Crushed between or against Vehicle related Collisions Vehicles over edges or rollovers Vehicle runaway on slope or gradient

15 Contractor/Principal Employer Serious injuries by employment type - normalised data 8 Serious injuries Full-time Company Part-time Company Full-time Contractor Part-time Contactor Principal employees Contractor employees 63853

16 Findings Data consistent with fatality review Data fits the accident triangle method of analysis 3D charts can pinpoint critical activities Methods fit the Risk based regulator concept Data results consistent with general accident theory Six month data sets useful because of sample size Over ten years of consistent data available Longer time frame required for low frequency high consequence events

17 Resources Safety s focus 17

18 Our commitment To work with industry to reduce serious accidents and incidents, and provide tangible support in achieving a positive cultural change. 18
