Learning Objectives

By the end of this lesson, you will be able to:

  • Identify the key regulations under the OHS Act related to incident investigation
  • Explain the specific requirements for reporting different types of incidents

Key OHS Act Regulations

General Administrative Regulations (GAR)

These regulations provide the administrative framework for the OHS Act. Chapter 7, specifically, deals with incidents, including definitions, reporting requirements, and investigation procedures for all workplaces.

Major Hazard Installation (MHI) Regulations

These regulations apply to sites with large quantities of hazardous substances. They have specific and stringent requirements for incident reporting, emergency planning, and investigation of any incident that could lead to a major accident.

Driven Machinery Regulations

These regulations focus on the safe use of machinery and contain specific requirements for reporting incidents involving equipment failure, entanglement, or other machinery-related accidents.

Environmental Regulations for Workplaces

These regulations address issues like ventilation, lighting, and noise. Incidents related to environmental conditions (e.g., heat stress, chemical exposure) fall under these requirements.

Reporting Requirements and Timeframes

Fatality

Report to Inspector immediately

Injury

Report within 7 days

Occupational Disease

Report within 14 days

Dangerous Occurrence

Report as soon as possible

The Investigation Process Under Regulations

Regulatory Investigation Steps

When a serious incident occurs, the regulations mandate a specific process to be followed:

1. Immediate Notification to Inspector
2. Secure the Incident Scene
3. Conduct Internal Investigation
4. Submit Investigation Report (Form WCIW)
Form WCIW: Investigation Report

The regulations prescribe the use of Form WCIW (Workplace Compensation Incident Report) for documenting and reporting the findings of an investigation. This form requires detailed information about the incident, the causes, and the corrective actions taken.

Inspector’s Powers

An inspector has the authority to take charge of the scene, question witnesses, seize evidence, and direct the employer’s investigation. Cooperation with the inspector is a legal requirement.

Record Keeping

Employers are required to keep records of all incidents, investigations, and reports for a minimum period of three years. These records must be made available to inspectors upon request.

Key Sections of the General Administrative Regulations

Section 2: Definitions

Defines “incident,” “injury,” “occupational disease,” and “dangerous occurrence.”

Section 3: Incidents to be Reported

Lists the specific types of incidents that must be reported to an inspector.

Section 4: Reporting to Inspector

Specifies the timeframes and procedures for reporting incidents.

Section 9: Investigation

Outlines the employer’s duty to investigate incidents and submit reports.
