Which of the following is part of the initial questions an investigator should ask regarding an incident?

The option addressing where workers went after the incident is crucial for several reasons. Understanding the immediate actions taken by workers post-incident can provide insights into their safety, the evacuation procedures followed, and how effectively the situation was managed. This inquiry helps in assessing whether proper protocols were in place, ensuring everyone was accounted for, and determining if any further risks were presented to workers after the initial incident.

Additionally, knowing where workers went can reveal information about their emotional and physical state following the incident, which can be important for both their well-being and for any necessary follow-up actions or investigations. Information gathered from this question can also contribute to improving safety protocols and emergency response plans in future situations, demonstrating a proactive approach to workplace safety.

The other options, while potentially relevant in different contexts of the investigation, do not focus directly on the immediate aftermath of the incident itself, which is critical during the initial questioning phase. Understanding immediate worker actions is vital for comprehensively evaluating the incident's circumstances and the effectiveness of the organization's response.
