Free Certified Fire and Explosion Investigator (CFEI) Exam Questions and Answers
The Certified Fire and Explosion Investigator is awarded by the National Association of Fire Investigators, not by NFPA — a distinction worth knowing before you book, because the two are easy to confuse. CFEI is built on NFPA 921, the Guide for Fire and Explosion Investigations, and NFPA 1033, the professional qualifications standard for fire investigators; NFPA writes those documents, and NAFI's National Certification Board runs the credential that tests you on them. It is the standard credential for origin-and-cause investigators working for fire departments, insurers and private investigation firms, and NFPA 921 is what opposing counsel will cite in court.
