Which NFPA standard currently sets the ISO qualifications for NIMS safety officers?

The NFPA standard that sets the qualifications for Incident Safety Officers (ISOs) is NFPA 1521. This standard specifically addresses the qualifications, training, and responsibilities related to safety officers in the context of emergency response. It is essential for ensuring that safety officers are equipped with the necessary knowledge and skills to carry out their responsibilities effectively, including maintaining safety during incidents, managing risk, and ensuring compliance with safety regulations.

While other standards mentioned may relate to fire service safety and training in different contexts, NFPA 1521 is specifically tailored to the role of incident safety officers, making it the appropriate choice for standardizing their qualifications within the framework of NIMS (National Incident Management System). This distinction is crucial for maintaining high safety standards and efficient incident management across various emergency scenarios.
