The Problem Isn't You. It's How It Was Explained to You.

You're standing in a burnt-out front room. The window glass is crazed, there's spalled concrete by the door, and the officer next to you asks: does that mean an accelerant was used?

You know you've read about it. But the manual gives it three pages of paragraphs, buried between old investigation beliefs and a list of studies. At the scene, none of it comes back in order.

Crazing comes from cooling water; spalling has many causes; neither proves accelerant.

In the book it's one page. Crazed glass drawn next to a hose stream: crazing comes from cooling water. Spalled concrete with its many causes. And a box underneath: neither one proves an accelerant.

The same goes for the V pattern and its angle, char depth measured with a probe, arc beads against fire melt, the plume and the ceiling jet, and sampling for ignitable liquids. Each one has its own page.

So you answer the officer calmly, note it properly and carry on with the scene. You understand it, and you do it without going back to the manual.

The Same Topic, Two Ways to Study It

THIS
  • The manual: line after line
  • Flashover and fire dynamics explained only in words
  • You walk into the exam still unsure
Flashover is generally described as the transition from a fire in which only the first item or a limited number of items are burning to a condition in which all exposed combustible surfaces within the compartment become involved. Although no single criterion is universally accepted, the literature commonly associates its onset with upper layer gas temperatures in the region of 500 to 600 °C and a radiant heat flux at floor level of approximately 20 kW/m², subject to considerable variation with compartment geometry, ventilation and fuel load.
FOR THIS
  • Flashover in one drawing
  • The guide values in one box
  • You see it and you understand it

One Page, One Topic, All Clear

Think of it this way:

You're in a kitchen gutted by fire. The heaviest damage is on the ceiling above the fridge, not by the cooker, and you need to know whether that's really where it started.

You open the book at the plume and ceiling jet page and see it drawn: the plume rising, the hot gases running along the ceiling, and why the worst damage can sit away from the origin.

Low points, protected areas and porous materials, plus a comparison sample of the same material

The same with flashover and its guide values, the V pattern, arc beads against fire melt, and where to take samples for ignitable liquids: each one on its own page.

Fire Investigation Illustrated is 66 illustrated pages in 9 parts, ending with the whole method on one page, the numbers and terms to have to hand and a checklist before you sign your report.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I've been in the fire service for 20 years?

Yes. It isn't a beginner's book: it puts what you already know into one order, from least to most damage to the signed report, with UK practice throughout. It also works for loss adjusters and scene examiners.

Where does the content come from?

Written for UK practice, not a translated American book. It follows the topic areas of the IFE Level 3 and Level 4 Certificate in Fire Investigation, the Forensic Science Regulator's Code of Practice, the Fire and Rescue Services Act 2004, CrimPR Part 19 and CPR Part 35. NFPA 921 appears only where UK practice refers to it, such as the cause classes. Court rules cited are those of England and Wales: if you work in Scotland or Northern Ireland, check your own procedure. Every legal reference comes with its source, so you can look up the current version.

Is it official material?

No. It's an independent study book, not produced, endorsed or approved by the IFE, any Fire and Rescue Service, the police or the Forensic Science Regulator. It doesn't come with a certificate: the IFE certificate comes only from passing the IFE exam.

Does it replace the course or my training?

No. It doesn't replace your course, supervised scene work or your organisation's procedures. It helps you study and revise them in order.

Are the practice questions the ones in the exam?

No. They're written for this book, in exam style, to help you find your weak spots. They aren't official IFE questions.

When and how will I get it?

The book and the 2 free books arrive as a PDF by email, at the address you enter at checkout.

Do I have to pay every month?

No. It's a one-off payment, with no subscription.

Can I have it on paper?

Yes. The PDF is ready to print: print it at home or at a print shop and keep it in the van.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.
