Which of the following is monitored by the Incident Safety Officer (ISO)?

The Incident Safety Officer (ISO) plays a critical role in ensuring the safety and well-being of all personnel at an incident scene. Monitoring personal protective equipment (PPE) compliance is crucial because it directly impacts the safety of firefighters and other responders. The ISO observes whether personnel are using the appropriate PPE based on the specific hazards present at an incident, which can include gear such as helmets, gloves, masks, and turnout gear. By ensuring compliance with PPE standards, the ISO helps to minimize the risk of injury or exposure to unsafe conditions for all responders involved in the operation. This oversight is a fundamental responsibility of the ISO, making it essential for maintaining a safe incident environment.

The other choices, while important in their own contexts, do not fall under the direct responsibility of the ISO during an incident response, as they pertain to broader operational or administrative areas rather than immediate on-scene safety concerns.
