Which aspects should be documented during an incident investigation?

1. Witness demographics

2. Physical evidence

3. Both A and B

4. None of the above

The correct answer is: Both A and B

During an incident investigation, it is essential to document both witness demographics and physical evidence to create a comprehensive understanding of what transpired. Recording witness demographics provides critical context regarding the individuals involved or who observed the event. This includes information such as their names, roles, and perspectives, which may be relevant to understanding their accounts and how their functions might have contributed to or been affected by the incident. In addition to witness accounts, documenting physical evidence is paramount as it includes any tangible items or conditions that can be analyzed, such as tools, equipment, and the environment where the incident occurred. This evidence helps to establish the factual basis of the incident, allows investigators to identify root causes, and provides insight into potential safety failures. By capturing both these aspects, the investigation can ensure a more thorough analysis, helping to prevent future incidents by addressing the underlying causes identified through both eyewitness accounts and physical evidence.
