Which NFPA standard lists the ISO requirements, duties, and responsibilities?

The correct answer is NFPA 1561, which specifically addresses the requirements, duties, and responsibilities of an Incident Safety Officer (ISO). This standard provides a comprehensive framework to ensure safety practices are maintained during emergency operations, detailing the necessary qualifications and functions of the ISO role. NFPA 1561 emphasizes the critical nature of incident safety and outlines how the ISO should implement safety measures, conduct risk assessments, and ensure that all personnel on the incident scene are operating under safe conditions.

By focusing on these key responsibilities, NFPA 1561 serves as an essential reference for fire service organizations and emergency responders to enhance their operational safety protocols. The standard effectively guides Incident Safety Officers in their duties to oversee safety adherence and mitigate hazards that may arise during incidents.
