What is an indicator of potential occupants who may witness or be involved in an incident?

Bystander accounts serve as a crucial indicator of potential occupants who may witness or be involved in an incident. These individuals, being present at the scene, can provide firsthand observations that can help emergency responders understand the situation better, including details about the nature of the incident, the number of occupants present, and their potential actions. Their testimonies can also assist in establishing a timeline of events leading up to and during the incident, which is invaluable for investigation purposes.

While other choices, such as security camera footage, can provide visual evidence and improve situational awareness, they do not necessarily indicate the presence of occupants as effectively as direct accounts from individuals who may have been involved. Fire alarm systems are designed to alert occupants of danger but do not provide information regarding the occupants themselves or their actions. Public announcements can disseminate information but do not directly indicate who might be present and involved in an incident. Thus, relying on bystander accounts can give responders important insights into the dynamics of a scene during emergencies.
