A thorough accident investigation involves several key steps, including reporting the incident, securing the scene, collecting data, analyzing the data to identify root causes, developing a corrective action plan, implementing the plan, and evaluating its effectiveness for continuous improvement. [1]

Here's a breakdown of the process:

• Initial Response and Reporting: Report the incident to a designated person immediately. Provide first aid and medical care to any injured individuals and prevent further injuries or damage.
• Investigation Team: Ideally, the investigation should be conducted by a team or person experienced in incident causation models, investigative techniques, and knowledgeable in legal/organizational requirements, occupational health and safety, work processes, and data collection.
• Scene Management and Data Collection: Secure the scene and ensure it is safe for investigators. Collect data by examining the site, equipment, products, safety devices, and environmental conditions. Take photos before anything is moved.
• Witness Management: Interview witnesses as soon as possible, keeping them separate to avoid influencing their accounts. Emphasize the purpose of the investigation is to determine what happened and why, not to assign blame.
• Data Analysis and Root Cause Identification: Analyze the collected data to identify the root causes of the incident. Consider all possible causes and contributing factors, not just the immediate or obvious ones.
• Corrective Actions: Develop specific and constructive recommendations to prevent similar incidents in the future. Focus on correcting weaknesses in processes or management systems.
• Reporting and Communication: Prepare a written report detailing the sequence of events, identified causes, and recommendations. Communicate findings and recommendations to workers, supervisors, and management.
• Follow-up: Management is responsible for acting on the recommendations. Monitor the progress of corrective actions, check on injured workers, and provide education and training to prevent recurrence.

In the event of a blasting accident or unusual occurrence affecting the safety of employees where explosive materials are involved, the employer shall within 24 hours forward a report of the incident to the Division. [9]
