These are real pages from the book. The table of contents is the full one: 8 parts and 63 topics.

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

You're standing under an open slab with a sealed pipe, a submittal binder and a GC waiting for a pass or a fail. And you don't know where to start.

The manual covers the check in paragraphs: system, assembly, penetrating item, annular space, materials and label, all mixed into ASTM text. Nothing tells you what comes first.

System, assembly, item, gap, materials, label: the 6-step circle used across the whole book.

In the book, that check is one page: a circle of 6 steps, drawn. System, assembly, item, gap, materials, label, always in that order.

Same with the system sheet, the F and T ratings, electrical boxes in rated walls, head-of-wall joints and E2174 sampling: each one has its own page.

You walk the floor, run the same 6 steps on every penetration and make the call without going back to the manual.

COMPARE FOR YOURSELF

The Same Topic, Two Ways to Study It

THIS
  • The manual: line after line
  • System sheets explained only in words
  • You reread Item 4 and still miss the minimum depth
Each listed through-penetration firestop system is identified by an alphanumeric designation and is presented with its applicable F and T ratings, followed by numbered elements describing the components of the tested assembly. Item 1 generally defines the floor or wall assembly, including minimum thickness and construction; Item 2 defines the penetrating item, its material, nominal size and any permitted sleeve; Item 3 addresses the packing or forming material and its required compression; Item 4 specifies the fill, void or cavity material and its minimum depth. Notes may further restrict application.
FOR THIS
  • The system sheet in one drawing
  • The ratings and items 1 to 4 in a box
  • Item 4's minimum fill depth, marked on the drawing
Ratings, items 1 to 4 and the notes: how a listed system sheet is organized.

One Page, One Topic, All Clear

Think of it this way:

It's the night before the exam, or the morning you walk a floor, and you need to know if a plastic pipe through a 2-hour wall matches its listed system.

You open the page for plastic pipe and see it drawn: the wall, the pipe, the intumescent device, the annular space with its min and max, and the label right next to it.

Cable fill limits range from about 11% to 100%: read the system

Same with metallic pipe, cable trays, head-of-wall joints, the T rating exceptions and E2174 sampling: each one on its own page.

Firestop Inspector Illustrated is 67 pages: 8 parts and 63 topics, all drawn, ending with the field defects, the numbers to keep at hand, an exam review map and a pocket jobsite checklist.

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

Frequently Asked Questions

Is it for me if I already inspect concrete or steel and now I'm being assigned firestop?

Yes. If you inspect concrete or steel and are new to firestop, it starts from the basics: the IBC firestop requirements, the F, T, L and W ratings, how to read a listed system, penetrations and joints, and E2174/E2393 inspection. It also covers what the International Firestop Council (IFC), FM and UL firestop exams have in common, with a page on FM 4991, the UL programs and the DRI. It isn't the official study guide for any of them, so check your exam's own reference list. If you already install firestop, you'll spend most of your time on the 6-step check and the field defect pages.

Where does the content come from?

Written against the 2024 International Building Code (Sections 714, 715 and 1705) and the current editions of ASTM E814/UL 1479, ASTM E1966/UL 2079, ASTM E2307, ASTM E2174 and ASTM E2393. If your jurisdiction adopted an earlier IBC, some section numbers and exceptions can differ, so check the edition that applies to your project.

Is this official material?

No. It's an independent illustrated study aid. It isn't published or endorsed by the IFC, FM Approvals, UL, ASTM or the ICC, and the system numbers in the drawings are teaching examples.

Does it replace a course or training?

No. It helps you study and review, but it doesn't give you a certificate, a credential or continuing education credits. It doesn't replace formal training, the code, the manufacturer's instructions or the actual listed system documents.

Are the practice questions the ones on the exam?

No. They're written for this book, in the style of the firestop exams, each with the answer and the page that explains it. They aren't official exam questions.

When and how do I get it?

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

Do I have to pay every month?

No. It's a one-time payment. No subscription.

Can I have it on paper?

Yes. The PDF is printable, so you can print the whole book or just the pages you want to keep on the jobsite.

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.

Before You Close This Page

No more rereading without anything sticking.

Annular space and fill depth: you see them drawn, and that's it.

You walk into the exam knowing where everything is.
