Which NFPA standard establishes job performance requirements for fire investigators?

• A. NFPA 1561
• B. NFPA 1033
• C. NFPA 1901
• D. NFPA 1962

Answer: (B)

Professional qualifications for fire investigators are defined by NFPA 1033. This standard specifies the minimum job performance requirements for investigators, detailing the knowledge, skills, and abilities they must demonstrate to conduct credible origins-and-causes investigations, collect and preserve evidence, document findings, and prepare accurate reports while following safety, legal, and ethical guidelines. It also supports training programs and certification by providing objective criteria that ensure investigators meet a consistent level of competence across jurisdictions. The other standards cover different areas—incident management, fire apparatus, and fire hose and fittings—and do not address investigator qualifications, making NFPA 1033 the correct choice.
