1. Section 24: When Are You Legally Obligated to Notify the DoEL?

When a workplace accident occurs, managing the immediate medical emergency is always the top priority. However, within minutes of stabilizing the injured worker, strict statutory reporting clocks begin ticking under the Occupational Health and Safety Act (Act 85 of 1993).

Under Section 24(1), an employer is legally obligated to notify the Provincial Director of the Department of Employment and Labour (DoEL) immediately by the quickest practical means (phone, email, or direct hand delivery) if an incident results in specific severe outcomes.

Section 24 reporting is triggered whenever an incident causes: the death of any person; an injury resulting in the permanent loss of a limb or part of a limb; any injury or illness where the victim becomes unconscious or suffers heatstroke/toxic inhalation; or an injury that causes an employee to be unable to work for 14 days or longer.

2. The Golden Rule: Preserving the Incident Scene

One of the most frequent mistakes made by factory supervisors is cleaning up the incident area, washing away blood, or restarting machinery immediately after an ambulance departs.

Under Section 24(2), where an incident has resulted in death or severe injury, no person may disturb the site or remove any machinery, tools, or physical evidence without the prior written consent of an inspector from the Department of Employment and Labour.

The only legal exceptions to this rule are actions strictly necessary to rescue trapped persons, administer life-saving first aid, or prevent catastrophic secondary disasters like major fires or structural collapses. Tampering with an accident scene is a criminal offense under the OHS Act.

3. General Administrative Regulation 9 & The Annexure 1 Investigation

While Section 24 governs external government notification, General Administrative Regulation 9 (GAR 9) governs the employer's internal investigation responsibilities.

GAR 9 stipulates that an employer must investigate every reportable incident within 7 days of its occurrence. The investigation must be led by the employer or a competent designated person, assisted by the elected Section 17 Health and Safety Representative for that work area.

The entire findings of the investigation must be recorded on the standardized statutory Annexure 1: Recording and Investigation of Incidents form. The completed form must be signed by the lead investigator, the SHE Rep, and the Chief Executive Officer or Section 16(2) appointee, and must be retained in the company's safety file for a minimum of 3 years.

4. Applying 5-Whys and Fishbone Root Cause Analysis

A superficial investigation that concludes 'the operator was careless' or 'human error' will be torn apart during a DoEL Section 32 formal inquiry or a Labour Court damages trial.

Professional investigators look past the immediate trigger to uncover systemic management failures using structured Root Cause Analysis (RCA) methodologies such as the 5 Whys and the Ishikawa Fishbone Diagram.

A robust investigation dissects four core operational failure categories: Machine & Equipment defects (unguarded nip points, failed limit switches), Environmental factors (poor illumination, oily floors), Procedural failures (inadequate Safe Work Procedures, lack of Lockout/Tagout), and Management failures (inadequate training, rushing deadlines, lack of supervision).

5. The 7-Step Post-Incident Emergency & Legal Roadmap

01
Provide Immediate Medical Aid & Secure the Scene

Deploy appointed First Aiders, call emergency medical services, and cordon off the entire physical perimeter with danger tape to preserve all evidence.

02
Determine Statutory Reporting Triggers (Section 24)

Assess if the injury involves death, amputation, unconsciousness, or 14+ days off work. If yes, notify the Provincial DoEL Inspectorate immediately.

03
Gather Physical Evidence & Photographic Records

Take high-resolution photographs from multiple angles, record equipment settings, inspect machine guards, and note weather and lighting conditions.

04
Conduct Separate Witness Interviews

Interview the injured worker, eyewitnesses, and the direct supervisor individually. Obtain signed, dated written witness statements.

05
Convene Joint Investigation with Appointed SHE Reps

Conduct the formal GAR 9 root cause analysis collaboratively with the area Health and Safety Representative and maintenance engineers.

06
Complete Statutory Annexure 1 & COIDA WCL 2 Forms

Document all findings on the official DoEL Annexure 1 form and submit the WCL 2 Employer's Report to the Compensation Commissioner within 7 days.

07
Implement Corrective Actions & Update Risk Assessments

Install physical engineering guards, rewrite Safe Work Procedures, re-train staff via Accredited Safety Training, and close out corrective actions.

Frequently Asked Questions

How quickly must an employer submit a WCL 2 form to COIDA?

Under Section 38 of COIDA (Compensation for Occupational Injuries and Diseases Act), an employer must submit the formal WCL 2 (Employer's Report of an Accident) to the Compensation Commissioner within 7 days of receiving notice of the accident.

Who must sign the DoEL Annexure 1 incident investigation form?

The Annexure 1 form must be signed by the competent person who conducted the investigation, the area Health and Safety Representative who participated, and the Section 16(1) CEO or delegated Section 16(2) manager.

What is a Section 32 Formal Inquiry?

Under Section 32 of the OHS Act, the Department of Employment and Labour can institute a formal court-like inquiry into serious workplace fatalities or major disasters. Presiding inspectors have the power to subpoena witnesses, cross-examine management under oath, and refer findings to the National Prosecuting Authority for criminal prosecution.

Can an employee refuse to participate in an internal incident investigation?

No. Under Section 14 of the OHS Act, employees have a general statutory duty to cooperate with the employer and give information regarding health and safety incidents.
