All 17 Fire Extinguisher Classes & PASS flashcards. Free.
The whole deck, not a sample — Fire Extinguisher Classes & PASS is 17 cards, which is no longer than the 30 we give away on every deck, so there is nothing left to charge for. 11 pages, US Letter, black and white. Grades 9–12 / CTE and workplace-safety coursework.
No account, no email, no card details.
11 pages, and the backs are already right
Every front sheet is followed by its own back sheet with the rows reversed. Print double-sided, flip on the long edge, and answer number 7 is behind question number 7. Print a deck you built yourself, flip on the short edge, and every answer lands on the wrong card — which nobody finds out until sixty cards have been cut apart.
- 17 cards — counted out of the file, not rounded up
- Eight cards a sheet, with cut guides
- US Letter PDF, black and white, photocopier-friendly
- Print a set per student, every class, every year
17 cards. The lettered fire classes are a closed set in each country — five in the United States, five in Europe, six in Australia — plus the PASS mnemonic and the two numbers on a US rating label. Everything past that would be padding.
Every card here is cited to two independent sources
Two different organisations — not a standards body and a website reprinting it — and a script refuses the card if the two disagree, so the check runs on every card rather than on the ones somebody remembered to look at. A second specialist then re-verified this deck from sources of their own, without reading our citations first. A further 5,420 cards across 30 other decks were read end to end by a subject specialist instead, and we say which is which on every deck rather than averaging the two into one flattering word.
What 17 printed cards do that a screen does not
A phone deck is one card at a time. A printed deck is a pile you can split: the ones you know, the ones you nearly know, and the ones you keep missing. That third pile is the entire study session, and it is the thing a scrolling app hides from you.
- Print once, use all year. The licence covers a set per student, every class, every year.
- No device, no login, no data. Works in a cover lesson, on a bus, or at a kitchen table. Grades 9–12 / CTE and workplace-safety coursework, filed under career, tech & modern.
- Change what you disagree with. Every card loads into the free maker on this site. Reword it, drop it, add your own, reprint.
Here are all 17 cards
Check them against your own textbook before you spend anything.
- What a fire 'class' letter describes
- The fuel a fire involves — but the letters are assigned differently in different countries
- The class letters used in the United States
- A, B, C, D, K — NFPA 10's set. OSHA's own rule defines only A to D; K came from NFPA in 1998
- The class letters used in Europe (BS EN 2)
- A, B, C, D, F — there is no K, and no letter at all for electrical
- The class letters used in Australia and New Zealand
- A, B, C, D, E, F — E is electrically energised equipment
- Class A in the United States
- Ordinary combustibles — paper, wood, cloth, and some rubber and plastics
- Class A in Europe (BS EN 2)
- Fires involving solid materials such as wood, paper or textiles
- Class B in the United States
- Flammable or combustible liquids, flammable gases and greases — gases are inside Class B here
- Class B in Europe (BS EN 2)
- Flammable liquids — petrol, diesel, oils. Gases are not in Class B here; they are Class C
- Class C in the United States
- Energized electrical equipment — the rating is about the agent being non-conductive
- Class C in Europe (BS EN 2)
- Gases — methane, butane, hydrogen. It is not the US Class C, which is energized electrical
- Class D on both sides of the Atlantic
- Combustible metals in both systems — magnesium, titanium, zirconium, sodium, lithium, potassium (US wording)
- Class K
- A US class — cooking oils and fats in cooking appliances. Europe and Australia letter this F
- Class F
- A European and Australian class — cooking oils and fats, as in deep-fat fryers. The US letters it K
- Where electrical fires sit in the European scheme
- Nowhere in the letters — EN 2 classes fires by fuel, so electrical risk is described outside A–F
- PASS
- Pull, Aim, Squeeze, Sweep — the US mnemonic (OSHA, USFA) for operating a portable extinguisher
- What the number before the A means on a US extinguisher label
- Class A capacity — each point is about 1.25 gallons of water equivalent (US rating scheme)
- What the number before the B means on a US extinguisher label
- The square footage of flammable-liquid fire a non-expert should be able to put out (US rating)
Questions
- How do I print them double-sided?
- Double-sided, flip on the long edge. Every front sheet is followed by its own already-mirrored back sheet, so print them in the order they come and every answer lands on its own card.
- Can I edit the cards?
- Yes, and that is half the point. Once you own the deck, the "Buy & edit" button here opens all 17 cards in the free flash card maker on this site — reword a definition, delete the ones you do not teach, add your own, and print at anything from two to nine cards a page, rather than the fixed eight of the PDF.
- Can I print a set for every student?
- Yes. Personal and classroom licence: unlimited printing, every class you teach, every year you teach it. It does not cover reselling the file or passing it on to a colleague.
- What if I find a card that is wrong?
- Tell us and we fix it, and we publish what changed. We have withdrawn a whole deck from sale for being out of date rather than quietly patch it.
- Do I need an account?
- No. The file downloads straight away — no account, no email, no card details.
