What is the last step in the arrival process for the ISO?

The last step in the arrival process for the Incident Safety Officer (ISO) is checking into the accountability system. This step is crucial as it establishes the ISO’s presence at the incident scene and ensures that all personnel are accounted for. By checking into the accountability system, the ISO provides vital information that contributes to overall situational awareness and safety management on the scene.

This action also facilitates communication and coordination among various team members and ensures that everyone understands who is on-site, thereby minimizing confusion and enhancing safety protocols. It signals that all required personnel are in place and ready to engage in their specified roles, helping the incident command maintain an accurate personnel log. Furthermore, it allows the ISO to access the relevant information that may be necessary for them to effectively manage safety during the incident.

The other options, while important components of the overall arrival process, do not represent the final step. Donning PPE is critical for personal safety but is typically completed before checking into accountability. Announcing that the ISO has been assigned is important for communication but occurs as part of the broader engagement strategy, rather than being a finalizing action. Radio checks, while necessary for establishing communication, are often part of routine procedures that follow the accountability check rather than coming last in the sequence. Thus
