Workplace health and safety statistics

WorkSafe strives to provide useful work-related injury and disease data to assist you in creating and maintaining an injury free workplace. Statistical information has been expanded to cover a range of key subjects specifically for Western Australian workplaces including:

  • WA Key OSH Stats
  • Industry specific statistics for the period 2015/16 (available shortly). 

WorkSafe moves to the latest industry and injury coding standards

On the 1 July 2011, WorkSafe commenced using the latest versions of industry, occupation and injury coding standards for the reporting and investigation of all work related traumatic fatalities and lost time injuries and diseases in Western Australia.

The coding standards used from this date are:

  • Australian and New Zealand Standard Industrial Classification 2006 (ANZSIC 2006);
  • Type of Occurrence Classification System Third Edition Revision 1 (TOOCS 3.1); and 
  • Australian and New Zealand Standard Classification of Occupations First Edition (ANZSCO).​

ANZSIC 2006 and ANZSCO publications can be downloaded from the Australian Bureau of Statistics  (ABS) website. The ABS site also provides correspondence tables and indexes of primary activities for ANZSIC 2006 to help you find where your organisation fits in the new industry structure.

TOOCS 3.1 can be downloaded from the Safe Work Australia website.

In terms of data reporting, a break in series has occurred. This means data is not comparable between the older and updated versions due to the structural and definition differences. 

For example, under ANZSIC 1993 manufacturers who sold their produce directly to end consumers, such as bakeries, would be classified as retailers (class 5124 Bread and Cake Retailing, group 512 Specialised Food Retailing, subdivision 51 Food Retailing, Division G Retail Trade); in ANZSIC 2006 this has been changed so that businesses that manufacture and sell their product on the same premise are classified under manufacturing (class 1174 Bakery Product Manufacturing (non-factory based), group 117 Bakery Product Manufacturing, subdivision 11 Food Product Manufacturing, Division C Manufacturing).

Another difference is the TOOCS coding definition of the mechanism of injury; in TOOCS 3.1 it is to identify the circumstances of the incident rather than the direct cause of the most serious injury/disease as defined in TOOCS 2.1.

Therefore, time series data analysis is not possible across coding versions and will not be possible in the updated versions until at least three years of data has been recorded (available in July 2013). As such the reporting years up to and including 2008-2009 data will remain in the older classification versions (ANZSIC 1993, TOOCS 2.1 and ASCO); data for the reporting year 2009-2010 and beyond will be reported in the updated classification versions ANZSIC 2006, TOOCS 3.1 and ANZSCO). 

The break in series does not affect data reporting at an overall National and State level, but will be evident when reporting on detailed topics such as industry divisions and injury types etc. Where appropriate, notations will be included warning readers of the danger of comparing statistics across a break in series.

2008-09 Data note

Industry denominator data (numbers of employees and numbers of hours worked) used to calculate incidence and frequency rates are provided by the Australian Bureau of Statistics (ABS).  Industry denominators coded to Australian and New Zealand Standard Industry Classification (ANZSIC) 1993 has been applied to claims data up until the 2007-08 lodgement year. However, due to implementation of a new ANZSIC version (ANZSIC 2006), denominators applicable to claims lodged in 2008-09 have been retrospectively converted to ANZSIC 1993. Although industry divisional level incidence and frequency rates are not impacted by this change, some variations are evident at the sub-industry level.

As such, caution is advised when using sub-industry rates in relation to the 2008-09 preliminary data; an asterisk symbol denotes sub-industries with significant variations. This will not be an issue in future years as claims for lodgement years 2009-10 onwards are being coded to ANZSIC 2006.

Note that TOOCS3.1, ANZSCO and ANZSIC 2006 codes are being applied to all claims lodged from 1 July 2009 onwards.
