Additional measures depend on the development of the incident. The correct multiple-choice option is (1).
Step-by-step explanation:
Upon arriving at the scene of a building explosion where people are fleeing and reporting that others are passing out, the appropriate first response is to carefully assess the situation and ensure your own safety. This includes dressing with proper equipment such as fire-resistant clothing and breathing apparatus, and using a two-way radio to assess fires and situations to report conditions to superiors. Once safety is ensured, the next steps would involve assisting with the evacuation, beginning triage and administering necessary first aid and cardiopulmonary resuscitation to injured persons. Notifying dispatch should be done to communicate the need for additional resources, but not to prematurely classify the event as a terrorist attack without further information. Contacting the FBI would be a measure taken by higher authorities when the nature of the incident is confirmed.
In the context of fire emergencies, it is essential for emergency workers to possess skills in decision making, teamwork, communication, and stress management. These skills ensure fast and efficient action in chaotic situations, translating to a better outcome for victims and workers alike. The correct multiple-choice option is (1).
