Investigations and PINs
Investigating incidents - advice for safety and health representatives
The document below provides useful information on how an investigation is run. It is not intended to be a detailed ‘how-to-do-it’ manual. Rather, it aims to assist safety and health representatives to understand the principles involved in conducting an investigation and provide procedural hints should they become involved in an investigation, including:
- What to look for
- Conducting an investigation
- Principles of investigation
- Checklist to establish the facts
- Checklist to determine recommendations and conclusions.
Provisional improvement notices (PINs)
Only elected safety and health representatives who have completed the training required to become a qualified safety and health representative can issue a provisional improvement notice (PINs).
PINs are issued at the mine where the safety and health representative works (or if elected by a group, at a mine where any member works) if he or she believes that there is a breach of the Mines Safety and Inspection Act 1994 (WA) or regulations.
The pamphlet below provides answers to the following questions:
- What is a PIN?
- Who can issue a PIN?
- Is there any consultation before a PIN?
- What must the employer do if someone is issued with a PIN?
- What if a person misuses the poewr to issue.
A flowchart and form is also provided.
