Section 1 - Background and Purpose

(1) Incident investigation is an important process to determine the events and factors that led to a hazard, injury, illness, incident or other system failure. 

(2) Through the process of conducting incident investigations, an understanding develops of the relationship among the events, and in doing so, provides clarity for organisational action in the effort to prevent reoccurrence. 

(3) The purpose of this Procedure is to provide a clear framework on how health and safety incidents are investigated so that necessary corrective actions and the lessons learnt are identified and implemented across the organisation in the effort to prevent reoccurrence.

Part B - Incidents Requiring Investigation

(9) All Health and Safety incidents will be investigated. 

(10) The level of investigation will be determined by the incident rating as described using the University risk matrix and utilising the following:

  1. Typically, the following incident types will require full incident investigation:
    1. Incidents with high potential consequence
    2. Incidents of high consequence with material damage 
    3. Incidents resulting in Lost Time Injuries
    4. Incidents resulting in Serious Injuries
    5. Notifiable Incidents

(11) Incident investigation will be initiated as soon as possible after the incident is reported through either:

(14) PEEPO contributing factors:

  1. People 
  2. Environment
