Final answer:
The NFPA does not specifically outline the duties of a public information officer; these duties are often informed by local policies and federal laws like the Freedom of Information Act.
Step-by-step explanation:
The principled duties of a public information officer within the context of emergency services and response are not directly outlined within the National Fire Protection Association's (NFPA) standards.
Instead, the role of a public information officer is typically associated with the management of information and communication during emergency situations.
The NFPA does provide guidelines related to communications and incident management such as NFPA 1561, Standard on Emergency Services Incident Management System, but for the specific duties of a public information officer in regards to public communication, local government policies, or federal laws such as the Freedom of Information Act (FOIA) would be more directly relevant.
This Act gives the public and media certain rights to access federal records, which may be pertinent to requests that a public information officer would handle.
Furthermore, the duties and responsibilities might be specified in local statutes or policies rather than a standalone NFPA standard.
