These are real pages from the book. The table of contents is the full one: 8 parts and 67 topics.
You're standing at the tape line of a two-story house that burned last night. The engine company has cleared, and you have to decide whether it's safe to go in.
You read the safety chapter. But it's paragraphs: structural stability in one place, utilities in another, hazardous materials further on. Standing in the driveway, you can't line them up.
In the book, that check is one page: the house drawn from the curb, with structure, power, gas, hazmat, floor holes and toxic debris marked in order, and a box that says it plainly: never alone.
The same goes for flaming vs. smoldering, the four fire effects behind every pattern, area vs. point of origin, the four elements of cause and how to package an ignitable liquid sample. Each one has its own page.
You see the page, you run the check, and you walk in knowing what you've ruled out, without going back to the manual.
The job and the method, fire science, safety and documentation, fire patterns, origin, cause, evidence and the law, and the report and testimony: 71 pages, all illustrated
Think of it this way:
You're in the kitchen of a burned house. The V pattern on the wall points one way, the char depth on the cabinets points another, and you have to commit to an area of origin.
In the book you open the page on V patterns: the angle drawn next to the ventilation pattern it's often confused with, and when each one points to origin and when it doesn't.
The same with char depth, calcination, arc mapping, the four elements of cause and chain of custody: each one on its own page.
Fire Investigator Illustrated is 8 parts and 67 topics, all drawn, and it closes with a one-page scene checklist and the pairs most often confused.
What you see drawn, you don't have to memorize.
What the investigator does, NFPA 921 vs. NFPA 1033, the scientific method in seven steps, bias and the four cause classifications.
The fire tetrahedron, heat transfer, flash point and autoignition, heat release rate, the plume, flashover and ventilation-controlled fires.
Scene safety, legal entry, working from least to most damage, photography, sketches, notes, interviews and building systems.
Read a wall before you trust it: what a pattern is, V and its variants, clean burn vs. origin, char depth, calcination, spalling, glass and protected areas.
Commit to an origin you can defend: area vs. point, the four data sources, heat and flame vectors, arc mapping, debris layering and testing the hypothesis.
The four elements of cause, eliminating sources the right way, electrical evidence, appliances, smoking, spontaneous heating, fuel gases and natural causes.
Ignitable liquid samples, canines, chain of custody, spoliation, fatalities, incendiary indicators, vehicles, wildland and explosions.
The O&C report section by section, conclusions that hold up, Daubert and Rule 702, cross-examination and a one-page scene checklist.
At the end of the book: A one-page scene checklist, the pairs most often confused and NFPA 1033 mapped to the book.
Exam-style questions on origin, cause, patterns and evidence, each with the answer explained, so you can check what you know before the test.
The most frequent errors on scene and in the report, each drawn wrong and then right, so you catch them before an examiner or an attorney does.

Yes. It doesn't teach you fire from scratch: it puts what you know in the order NFPA 921 asks for, one drawn page per topic. Parts 5 to 8 cover what suppression rarely teaches: arc mapping, eliminating ignition sources, spoliation, Daubert and cross-examination.
It's checked against NFPA 921 (2024 edition) and NFPA 1033 (2022 edition), the standards behind US fire investigator certifications such as IAAI-CFI, NAFI-CFEI and Pro Board or IFSAC Fire Investigator. Each section reference is listed so you can check it in your own copy of the current edition.
No. It's independent study material. It isn't published, approved or endorsed by NFPA, IAAI, NAFI, the Pro Board or IFSAC, and it doesn't give you a certificate or continuing-education hours.
No. It's a visual companion for studying and reviewing. Your course, field training, the current NFPA 921 and your own professional judgment come first.
No. They're written for this book, in exam style, to check what you know. They aren't questions from any official exam.
