Which NFPA standard defines the duties of safety officers?

The duties of safety officers are defined by NFPA 1521, which specifically outlines the responsibilities and functions required for safety officers in the fire service. This standard provides guidelines for the role of incident safety officers and their critical mission to ensure the safety of personnel during emergency operations. NFPA 1521 emphasizes the need for safety officers to implement and enforce safety protocols, conduct scene assessments, and maintain a safer working environment for all responders.

This standard plays a crucial role in defining the expectations and requirements for safety officers, making it essential for fire departments and other emergency services to understand and adhere to these guidelines to enhance overall safety. While other standards, such as NFPA 1500, address broader safety and health issues in the fire service, NFPA 1521 is specifically focused on the safety officer's role, making it the correct choice for this question.
