Formation à l'enquête sur les incidents : pourquoi 80 % des entreprises sud-africaines se trompent sur les causes profondes

The Incident Investigation Crisis in South Africa

South Africa reports over 200 workplace fatalities annually and thousands of serious injuries. Behind each statistic is often a flawed investigation that blamed the worker instead of fixing the system.

The Department of Employment and Labour (DEL) increasingly scrutinizes investigation quality. Inspectors now look beyond the incident report — they want evidence of systematic root cause analysis and corrective action implementation.

Why Most Investigations Fail

Research shows that 80% of workplace incident investigations suffer from:

1. Blame culture — Concluding "the worker was negligent" and stopping there
2. Shallow analysis — Identifying immediate causes but missing systemic failures
3. No methodology — Investigators lack structured investigation frameworks
4. Poor evidence collection — Critical evidence lost in the first 24 hours
5. Weak corrective actions — Generic recommendations like "retrain workers"

Professional Investigation Methodologies

1. The 5 Whys Technique

Start with the incident and ask "why?" five times to drill down to root causes:

• Why did the worker fall? → The scaffolding collapsed
• Why did the scaffolding collapse? → It wasn't inspected before use
• Why wasn't it inspected? → No inspection protocol exists
• Why is there no protocol? → Management hasn't allocated resources to scaffold safety
• Why haven't they allocated resources? → OHS isn't integrated into operational planning

Root cause: Lack of management commitment to OHS integration (not "worker error").

2. Fishbone (Ishikawa) Diagram

Categorize contributing factors across six domains:

• People — Training, competence, supervision, fatigue
• Process — Procedures, work instructions, permit systems
• Plant/Equipment — Maintenance, guarding, suitability
• Place — Housekeeping, lighting, ventilation, access
• Policy — Management commitment, resource allocation, communication
• Performance — Monitoring, auditing, review mechanisms

3. Tripod Beta

A sophisticated methodology that traces incidents back through:

• Active failures (immediate unsafe acts/conditions)
• Preconditions (underlying factors enabling the failure)
• Latent failures (management and organisational deficiencies)

Legal Requirements for Incident Investigation in SA

The OHS Act and General Safety Regulations require:

• Section 24 — Recording and investigating incidents
• GAR 8 — Reporting incidents to the Provincial Director
• GAR 9 — Investigation of serious incidents by an inspector
• COID Act — Reporting to the Compensation Commissioner within 7 days

Failure to investigate adequately can result in:

• Criminal prosecution under the OHS Act
• Increased Workmen's Compensation levies
• Civil liability for negligence
• Department of Labour prohibition notices

Building Investigation Competence

Professional investigators need training in:

OHS Compliance Group's Investigation Training

Our incident investigation programme is designed for South African workplaces:

• Practical case studies from real South African incidents (Transnet, Eskom, construction sector)
• Hands-on exercises using fishbone diagrams, 5 Whys, and fault tree analysis
• Legal compliance module covering OHS Act reporting requirements
• Report writing workshop producing investigation reports that satisfy DEL inspectors
• Follow-up assessment ensuring corrective actions are implemented effectively

Our facilitators have personally investigated incidents across mining, construction, manufacturing, and transport — bringing real-world expertise to every session.
