Who regulates fire extinguisher service companies in Wyoming?

Wyoming State Fire Marshal's Office is the agency the research identified for this trade in Wyoming. Requirements and license classes change, so confirm the current rules with them directly.

How do I confirm the exact Wyoming requirements before my first job?

Contact Wyoming State Fire Marshal's Office and confirm, in writing, the company license or registration, the technician certification, and any surety bond or insurance filing your scope needs. Requirements vary by jurisdiction — verify with your AHJ (authority having jurisdiction) before you take paid work. This page is a starting point, not legal advice.

If Wyoming has no state company license, can I just start?

Not without checking. Even where there is no state license for the trade, you typically still need a business license, sales-tax registration, liability insurance, and possibly a local registration — and the NFPA service standards still govern the work. Verify the full picture locally before you quote a job.

What must a fire extinguisher service tag say in Wyoming?

This research pass could not read a Wyoming service-tag rule, so this page states none. There is no national tag standard to fall back on and no national colour code: NFPA 10 mandates no tag colour, and the per-state rules that do exist disagree with each other. Ask Wyoming State Fire Marshal's Office what a tag must carry here before you print one.

What the research found

State: Wyoming (WY)
Regulating agency: Wyoming State Fire Marshal's Office
Notes from the source: This pass found no primary source for any Wyoming fire-extinguisher or hood-suppression credential; the fire-prevention pages it reached cover adopted codes, inspectors and plan review, and the licensing surface it reached is electrical. Ask the State Fire Marshal's office before you take paid work.
Service tag: Verify with the agency
Adopted code: Wyoming's State Fire Marshal lists the 2024 International Fire Code among the codes that apply statewide.

Verify with your AHJ. This is a research-derived starting point, not legal advice. Rules change, and local requirements stack on top of state ones, so the only answer that governs your work is the one you get from Wyoming State Fire Marshal's Office and from your AHJ, the local authority having jurisdiction, before you take a paid job.

Which code edition applies in Wyoming

An NFPA standard is a private consensus document. It carries no legal force anywhere until a jurisdiction adopts it, and jurisdictions adopt different editions, years apart, with local amendments on top. So the useful question is never "what does NFPA 10 say". It is "which edition has my authority adopted, and what did they change".

For Wyoming the research found this adoption record: Wyoming's State Fire Marshal lists the 2024 International Fire Code among the codes that apply statewide. The record is linked in the at-a-glance table above and in the sources below.

Read that as the floor, not the ceiling. Your local fire marshal may enforce a later edition, an amended one, or a local ordinance the state record does not mention, and an adoption record can be superseded between one job and the next. Confirm the edition in force with Wyoming State Fire Marshal's Office and with the authority having jurisdiction where the work is.

What a service tag must carry in Wyoming

This research pass could not read a Wyoming service-tag rule, so this page states none. There is no national tag standard to fall back on: NFPA 10 mandates no tag colour, the popular "the colour tells you the year" rule is a vendor convention rather than law, and the state rules that have been read do not match each other. Ask Wyoming State Fire Marshal's Office what a tag must carry here, in writing, before you print a run of them.

The per-state picture, and why the colour folklore is wrong, is laid out in the state-by-state tag requirements guide and what a fire extinguisher tag colour actually means.

The cadence underneath all of it

Whether or not Wyoming licenses this trade, the intervals your customers owe are set somewhere else, and one layer of them is federal. Under OSHA's portable fire extinguisher regulation, an employer subject to OSHA has to have extinguishers visually inspected monthly and put through an annual maintenance check, wherever the building is. The state's adopted edition of NFPA 10 and the local fire marshal stack on top of that floor.

The interval that surprises people is the pressure test, because it is not one number: it depends on the agent and the shell, and a unit on the wrong assumption reads as current for years when it is not. The full picture, with the section of the federal regulation each interval comes from, is in the federal extinguisher intervals guide, and the by-type test schedule is in hydrostatic test intervals by extinguisher type. To put dates against a specific unit, the free cadence lookup takes a manufacture date and an equipment type and returns the next dates due. It is a planning aid, never a verdict on a building.
