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

You're in the van between jobs, looking at a 9-litre water unit with last year's label on it, and you can't say for sure whether it's due a basic or an extended service.

You went through the intervals last night. But the code of practice sets them out in paragraphs, clause after clause, with the exceptions in between, and by morning basic, extended and overhaul have blurred into one.

Day 0, monthly, every 12 months, year 5, year 10: the BS 5306-3 calendar on one line

In this book the whole calendar is one page: day 0, monthly, every 12 months, year 5 and year 10 on a single line, with what each stage involves drawn underneath.

Every other topic gets the same treatment: the extinguisher in exploded view, stored pressure versus cartridge, the discharge test, siting from the risk, the fire blanket. Each one has its own page.

You look, you get it, and you do the job without going back to the standard.

COMPARE FOR YOURSELF

The Same Topic, Two Ways to Study It

THIS
  • The standard: line after line
  • Stored pressure and cartridge units explained in words only
  • You turn up to the assessment still unsure
Portable extinguishers are classified according to the means by which the expellant gas is retained. In stored pressure extinguishers, the expellant gas, typically nitrogen or dry air, is contained within the body together with the extinguishing medium, and the internal pressure is generally indicated by a pressure gauge. In cartridge operated extinguishers, the expellant gas is contained in a separate cartridge, which is punctured upon operation, thereby pressurising the body. It follows that the procedures applicable at basic service, including internal examination and cartridge weighing, differ materially between the two types.
FOR THIS
  • Both units in one cutaway drawing
  • The checks for each type in one box
  • You see it and you get it
Stored pressure vs cartridge operated: two cutaways, one difference that changes the whole service.

One Page, One Topic, All Clear

Think of it this way:

It's Monday morning in a school kitchen. The CO2 by the door is ten years old and the site manager wants to know what happens to it now.

You open the book at the CO2 overhaul page and the unit is drawn with each stage of the overhaul set out in order, next to the service timeline.

Extended service every 5 years for water and powder; 10 for primary-sealed powder (BS 5306-3).

Same with the powder discharge test, the 30 m rule for Class A, wet chemical by the fryer, the service label and the fire blanket: each one on its own page.

Extinguisher Servicing Illustrated is 68 illustrated pages in 8 parts, one topic per page, and it ends with checklists for every service, the most frequent mistakes side by side and a last read for assessment day.

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

Frequently Asked Questions

Is it for me if I'm moving into extinguisher servicing from another trade?

Yes. It starts from what a fire needs to burn and builds up to the service and siting rules. It doesn't treat you as a beginner with tools: it shows you the standard in the order you work.

Where does the content come from?

From the current editions of BS 5306-3 and BS 5306-8, cross-checked with BS EN 2, BS EN 3, BS 7863, BS EN 1869, BS ISO 7010 and the Regulatory Reform (Fire Safety) Order 2005. It's written for the UK, not from American NFPA rules.

Is it official? Do I get a certificate?

No. It's an illustrated study book, not a qualification. It doesn't give you a certificate and it isn't a competence assessment: that comes from your employer or training provider. It isn't published or endorsed by BSI, BAFE or any certification body, and it doesn't replace the standards themselves.

Does it replace my training course?

No. It goes alongside your employer's training or your course provider and your supervised work on site, so you can go over everything in the same order.

Are the practice questions the ones in the assessment?

No. They're written for this book in the style of an assessment, and each answer points to the page that explains it.

When and how does it arrive?

As a PDF by email, to the address you enter at checkout. The 2 bonus books arrive the same way.

Do I have to pay every month?

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

Can I have it on paper?

Yes. The PDF is ready to print, so you can keep a copy 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.

Before You Close This Page

No more rereading the standard with none of it sticking.
