responsibilities of the Incident Safety Officer? --- --- --- --- --- ---
• A. NFPA 1500
--- --- ---

Services Incident Management System and Command Safety,
--- --- --- --- --- --- ---
which addresses the Safety Officer (SO) under NIMS . NFPA
--- --- --- --- --- --- --- --- --- ---
1851 (D) addresses selection, care, and maintenance of

3. The Incident Safety Officer (ISO) and Health and Safety
--- --- --- --- --- --- --- --- --- ---
Officer (HSO) roles were split into separate professional
--- --- --- --- --- --- --- ---
qualifications standards in: --- --- ---
• A. NFPA 1500 --- --- ---
• B. NFPA 1521--- --- ---
• C. NFPA 1561 --- --- ---
• D. NFPA 1026 --- --- ---
Answer: B --- ---
, Rationale: NFPA split the roles of HSO and ISO from NFPA
--- --- --- --- --- --- --- --- --- --- ---
1500 to NFPA 1521 (for HSO) and NFPA 1561 (for ISO) . NFPA
--- --- --- --- --- --- --- --- --- --- --- --- --
-
1521 is now written as professional qualifications with
--- --- --- --- --- --- --- ---
knowledge and skill objectives for both HSO and ISO . Prior to
--- --- --- --- --- --- --- --- --- --- --- ---
this separation, the safety officer function was addressed within
--- --- --- --- --- --- --- --- ---
broader standards. The distinction between the
--- --- --- --- --- ---
administrative/health focus of the HSO and the --- --- --- --- --- --- ---
operational/incident focus of the ISO is critical for understanding --- --- --- --- --- --- --- --- ---
fire department safety programs.
