Uniformat D3060
Gas detector
A gas detector lasts about 10 years, as stated by the one published source on file.
Also listed as Gas detection system, CO detector, NO2 detection, refrigerant leak detector
This is version 0.5.0. The latest is 0.6.0.
Service life
Years in service. One stated life so far; the band will widen as sources are added.
Work out when yours is due for replacement
One source. This value rests on a single document (UFM 3-601-02 Fire Protection Systems Inspection, Testing, and Maintenance (Unified Facilities Manual, 13 March 2026), p32). Treat it as that source's figure, not a settled life, until others confirm it.
Basis
- 10 years · UFM 3-601-02 Fire Protection Systems Inspection, Testing, and Maintenance (Unified Facilities Manual, 13 March 2026), p32 · Table 2-1 “Fire Detection and Alarm System ITM Tasks, frequency "10 Years": "Carbon Monoxide Detectors" - "Replace detectors."” — U.S. Department of Defense (Unified Facilities Criteria program) (planning life)Printed page 25. CO detectors connected to the building fire alarm system (section 3-4 distinguishes these from single-station CO alarms). Covers the CO detector heads only; NO2, refrigerant and combustible-gas detectors and the gas detection controller are not addressed.

Municipal lives for HVAC (D30)
48 municipalities in Ontario, British Columbia and Alberta state a life for HVAC as a whole, in 39 distinct tables: 10–50 years, median 20. 65 rows come from capital asset policies (accounting lives, used for amortization) and 6 from asset management plans (planning lives, used to forecast replacement). They describe the system rather than this component, and none is a measured life.
Years. Each dot is one stated life and each bar a stated range; equal values stack. Hollow marks are planning lives from asset management plans; filled marks are accounting lives from policies. The dashed line is the median. Policies that copy the same table count once.
