The standards that drive your equipment decisions
NFPA renumbered most of the fire service standards between 2024 and 2026, and a lot of dealer websites still quote the old ones. Here are the current numbers, what changed, and what it means when you're buying or retiring gear.
Current numbers at a glance
| Topic | Current standard | What it replaced | What it means for you |
|---|---|---|---|
| Turnout gear, SCBA, PASS, station wear | NFPA 1970, 2025 edition (effective Sept 2024) | NFPA 1971, 1975, 1981, 1982 | New gear and SCBA are built and certified to 1970. The last 1981-2018 SCBA shipped in March 2026. |
| Care, maintenance, and retirement of gear and SCBA | NFPA 1850, 2026 edition (effective Sept 2025) | NFPA 1851, 1852 | Turnout gear still retires at 10 years from manufacture. SCBA can stay in service up to 20 years with manufacturer upgrades. Retired SCBA must be destroyed, not resold. |
| Apparatus design and construction | NFPA 1900, 2024 edition | NFPA 1901, 1906, 1917, 414 | Applies to apparatus contracted on or after Jan 1, 2024, including fill-station containment requirements on new rigs. |
| Apparatus inspection, testing, refurbishment, retirement | NFPA 1910, 2024 edition | NFPA 1911, 1912, 1925, 1071 | The annual pump and aerial tests, refurbishment levels, and the 15/20/25-year retirement guidance live here now. |
| Breathing air quality | NFPA 1989, 2019 edition | (NFPA 1989 is scheduled to merge into NFPA 1985) | Quarterly lab testing of compressor air, plus retests after repairs, filter changes, relocation, or suspected contamination. |
| SCBA cylinder retest | DOT / PHMSA 49 CFR 180 and the cylinder's special permit | — | Composite cylinders: 5-year hydro, 15-year life (20 or 30 on newer permits). Aluminum: 5-year hydro, no life limit. Only a DOT-registered retester (RIN holder) may requalify. |
Standards get revised. This page reflects editions in effect as of October 2026; for a purchase or a grant application, confirm the current edition on nfpa.org and ask us for the manufacturer's certification letter.
What the breathing-air test checks
NFPA 1989 sets limits for the air that comes out of your fill station. The ones that fail most often are water and carbon monoxide.
| Contaminant | NFPA 1989 limit |
|---|---|
| Oxygen | 19.5–23.5% |
| Carbon monoxide | 5 ppm maximum |
| Carbon dioxide | 1,000 ppm maximum |
| Water vapor | 24 ppm maximum (dew point at or below −65°F) |
| Oil and particulate | 2 mg/m³ maximum |
| Non-methane hydrocarbons | 25 ppm maximum |
| Odor | None pronounced |
Oil-lubricated compressors also need a tamper-proof CO monitor that shuts the compressor down above 5 ppm. If yours doesn't have one, we can add it on an air-check visit.
SCBA cylinder service life
| Cylinder | Hydro retest | Service life |
|---|---|---|
| Carbon-fiber composite, standard DOT special permit (most 4500 psi cylinders) | Every 5 years | 15 years from manufacture |
| Carbon-fiber composite, extended-life permits (newer cylinders, label will say) | Every 5 years | 20 or 30 years from manufacture, per the permit on the label |
| Hoop-wrapped fiberglass composite (older low-pressure) | Every 3 years | 15 years |
| Aluminum DOT 3AL (2216 psi) | Every 5 years | No DOT limit while it passes |
The permit number, manufacture date, and retest interval are all printed on the cylinder label. When in doubt, the label wins over any rule of thumb, including this one. We coordinate hydro testing and will inventory your dates for you.
Rapid intervention and the universal air connection
Every SCBA certified since the 2002 edition of NFPA 1981 has a universal air connection (UAC) so a rescue crew can refill a downed firefighter's cylinder from an independent air source. A RIT/RIC pack needs the matching UAC fill hose. If your department still runs pre-2002 packs, that's the first thing an upgrade fixes.
Buying with these numbers in mind
- Spec new gear and SCBA to NFPA 1970 (2025). If a quote says 1971 or 1981, ask why.
- Used SCBA is fine to buy when it has years left under NFPA 1850's 20-year window and the manufacturer still supports it. Ask for the manufacture date on the backframe, not just the cylinders.
- Used turnout gear must be under 10 years from manufacture, with the date label intact, or it can't be placed in service.
- Used apparatus is judged under NFPA 1910: a current pump test and a documented inspection matter more than the year on the title.
Every quote we write names the standard each item meets, so your board, your grant reviewer, and your insurer see the same thing.
