What the research found
- State
- Tennessee (TN)
- Regulating agency
- Tennessee Department of Commerce & Insurance — Division of Fire Prevention
- Notes from the source
- Every Tennessee primary host failed this pass, on certificate errors or refused requests, so no claim about the requirement is made here. Ask the department's fire-prevention division directly before you take paid work.
- Service tag
- Verify with the agency
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 Tennessee Department of Commerce & Insurance — Division of Fire Prevention and from your AHJ, the local authority having jurisdiction, before you take a paid job.
Which code edition applies in Tennessee
An NFPA standard carries no legal force until a jurisdiction adopts it, and jurisdictions adopt different editions, years apart, with local amendments. So the useful question is never "what does NFPA 10 say". It is "which edition has my authority adopted".
This research pass did not reach an adoption record for Tennessee, so this page names no edition. That is a gap in what we could read, never a finding that the state adopts nothing. Ask Tennessee Department of Commerce & Insurance — Division of Fire Prevention which edition of NFPA 10 and which fire code are in force, and ask your authority having jurisdiction the same question, because the two answers are not always the same one.
What a service tag must carry in Tennessee
This research pass could not read a Tennessee 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 Tennessee Department of Commerce & Insurance — Division of Fire Prevention 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 Tennessee 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.
