Which responsibility does the ISO have in relation to life safety during an incident?

The responsibility of the Incident Safety Officer (ISO) in relation to life safety during an incident is to address life-safety concerns for responders and the public. This is a critical role within the Incident Command System (ICS), as the ISO is tasked with ensuring that all operations conducted during an incident prioritize the safety of personnel and the public.

This involves monitoring the scene for hazards, assessing risks, implementing safety measures, and communicating any safety issues or concerns to the Incident Commander and other responders. The ISO acts as a safety advocate, dedicated to preventing injuries and fatalities by promoting safe practices and ensuring that any response actions do not compromise life safety.

In contrast, performing an initial size-up is focused on assessing the overall situation and conditions of the incident but does not directly address safety concerns. Obtaining an initial situation-status briefing is about gathering information rather than actively managing safety risks. Making the final determination regarding ICS forms relates to administrative tasks and documentation, which do not specifically deal with life safety issues. Therefore, the ISO's primary duty involves proactive engagement with life-safety matters, making option B the correct choice.
