NFPA 10
Standard for Portable Fire Extinguishers
NFPA 10 is a standard issued by National Fire Protection Association covering selection, installation, inspection, maintenance, recharging, and testing of portable fire extinguishers.

Who enforces this, and how it reaches you
Enforced through OSHA 1910.157 at federal level and through state fire marshal offices and local AHJs at the point of inspection. In practice the inspector citing you works for the local jurisdiction, not NFPA, and cites the adopted code rather than the standard itself.
How this differs from the neighbouring standards
OSHA 29 CFR 1910.157 adopts much of NFPA 10 by reference, which is why the two read similarly. The practical split: OSHA is the enforceable federal obligation on an employer, and NFPA 10 is the technical standard describing how the work is done. A citation is written against OSHA; the method is argued from NFPA.
What you have to be able to show
NFPA 10 splits the work into a quick recurring check and a deeper periodic service, and the evidence for each looks different. The recurring check is fast and frequent, and it is the one that produces a visible mark on the tag attached to the extinguisher. The periodic service is performed by someone qualified to open and examine the unit, and it produces both a tag entry and a service record. Layered on top are the long-interval events - internal examination and hydrostatic testing - which recur on multi-year cycles and are usually evidenced by a collar around the neck of the cylinder rather than by the tag itself. The practical consequence is that a single extinguisher accumulates three different kinds of proof on three different clocks, and they are all supposed to be legible on the unit at the same time.
What the record adds that the tag cannot
The awkward part of a multi-year cycle is that the evidence has to survive longer than the thing carrying it. A six-year internal examination is proved by a collar that has to stay legible and attached through six Florida summers, or six winters of a cold warehouse. A twelve-year hydrostatic interval is worse. Tags get replaced annually, and every replacement is a chance for the history to reset to whatever the current tag says. A serialised record breaks that dependency: the serial is bound to the extinguisher, not to the piece of card currently hanging off it. Replace the tag next year and the six-year and twelve-year clocks are still there, still readable, with the dates that were actually recorded rather than the dates someone reconstructed from the oldest surviving collar.
The mechanics are the same for every standard, and they are set out on how inspection records work.
Why this is a different purchase from ordering the same item printed
A label printer will sell you NFPA 10 tags, and if all you need is card stock with your licence number on it they will do that perfectly well. The difference is where the transaction ends. Theirs ends when the box arrives. The tag then has to carry the entire evidentiary burden on its own, in the field, for a year. Here the tag arrives already knowing which record it belongs to, so the card is the index into the history rather than the whole of it. You were going to buy tags regardless. The question is whether the thing you buy is inert.
Choosing a substrate for this environment
Card stock is the default and it is the right default: most extinguishers live indoors, the tag is replaced annually, and card takes a ballpoint signature better than plastic does. The exception is anything mounted outside or in a wash-down area, where a year of humidity turns card soft and the initials bleed. UV cured plastic costs roughly twice as much per unit and is worth it exactly where the tag is exposed and nowhere else. The six year collar is a different decision, because it has to stay legible far longer than any tag: it is a moulded band sized to the cylinder neck rather than printed card on a punch hole.
Substrate and rating are stated on every product page. If you are not sure, compare the options or order the hundred unit minimum and see how it survives before committing a fleet to it.

Questions people ask about NFPA 10
Does a serialised tag replace the paper inspection tag?
No. It is the same physical tag, printed on the same substrate, with the same imprint and the same space for initials and dates. The serial and QR are added to it. Anyone can still read and sign it exactly as they do now, with no phone and no account. The scan is an addition to the tag, not a replacement for it, which matters because the inspector standing in front of the extinguisher may not be the person who bought it.
What happens to the record when the tag is replaced at the annual service?
The record belongs to the extinguisher, not to the tag. When a new tag goes on, it is bound to the same device and the history continues on the same timeline. This is the specific reason serialisation matters under NFPA 10 rather than under a standard with a single annual cycle: the six-year and twelve-year intervals outlive several generations of tag, and reconstructing them from whatever collar survived is how those dates drift.
Do you certify that our extinguishers comply with NFPA 10?
No, and you should be wary of any supplier that says otherwise. We manufacture the artifact and host the record. Whether a given extinguisher is compliant is a determination for the qualified person performing the service and, ultimately, for the authority having jurisdiction. What we can do is make sure the evidence of what was actually done is legible, durable, and still there in six years.
