Which of the following is NOT a phase of an accident investigation?

The phase that is not part of an accident investigation is employee discipline. An accident investigation primarily focuses on understanding the causes and circumstances surrounding an incident to improve safety and prevent future occurrences. This involves phases such as assessing the accident scene, collecting and analyzing relevant data, and generating a comprehensive report outlining findings and recommendations.

While addressing employee discipline may be a necessary outcome after an investigation, particularly if negligence or violation of safety protocols is identified, it does not fall under the investigative phases themselves. The aim of the investigation is to gather facts and insights objectively to enhance safety measures and practices. Therefore, employee discipline, which is often a separate process that might follow the investigation based on its findings, is correctly identified as not being a phase of the accident investigation.
