Final answer:
Where no IC direction is given, the ISO should start the SAFER action model if no imminent threat needs an intervention. (Option B)
Step-by-step explanation:
In incident command and emergency response, the SAFER action model stands for Size-Up, Actions, Follow-Up, Economic Considerations, and Risk Management. It is a structured approach used by the Incident Safety Officer (ISO) to assess and address the safety of responders and the public during an incident.
This model helps ensure that safety remains a top priority and that the incident is managed effectively while minimizing risks. Starting with a size-up of the situation, the SAFER model guides the ISO in taking appropriate actions, providing follow-up measures, considering economic factors, and managing risks as needed to maintain a safe and controlled response to the incident.
Therefore, the correct option is: B) SAFER
