Fire Extinguisher Inspection (NFPA 10)
An extinguisher that fails the moment someone reaches for it isn't a safety tool — it's a liability, and your inspection tag is the evidence. We handle monthly, annual, 6-year maintenance, and hydrostatic testing of portable fire extinguishers to NFPA 10 (2022) across Texas, with on-truck recharge capability and inventory tracking. TX SFM ECR #2370364.
What it is
NFPA 10 — the Standard for Portable Fire Extinguishers — requires monthly visual inspections, annual maintenance inspections with a service tag, 6-year internal maintenance for dry-chemical and certain other types, and hydrostatic pressure testing at intervals ranging from 5 to 12 years depending on extinguisher type. Texas Administrative Code Title 28, Chapter 35 adopts these requirements and requires that annual maintenance be performed by a licensed Texas SFM extinguisher contractor (ECR license). Zion holds ECR #2370364.
A portable fire extinguisher is the first-response tool for a contained fire. The problem is they look fine even when they're not. A dry-chemical extinguisher can pass a visual inspection while the agent inside is compacted, the pressure gauge reads acceptable, and yet the unit will not discharge correctly when the pin is pulled. NFPA 10's 6-year internal maintenance requirement exists precisely because external appearance is not a reliable indicator of serviceability. The 6-year service opens the extinguisher, inspects and replaces the valve components, and confirms the agent is not caked or stratified.
Zion services all extinguisher types: ABC dry chemical, CO2, wet chemical (Class K), clean agent (Halotron, FE-36), water-mist, and dry-powder (Class D). We carry replacement units and recharging equipment on every truck, so failed units are serviced on-site rather than tagged-out and removed, leaving your building coverage gap open for weeks.
What code governs it
NFPA 10 — Standard for Portable Fire Extinguishers (2022 edition) — Adopted under TAC Title 28, Chapter 35 for Texas commercial buildings
Texas adoption: TAC Title 28, Chapter 35 — annual inspection and maintenance must be performed by a TX SFM extinguisher contractor (ECR license). Zion: TX SFM ECR #2370364.
International Fire Code reference: IFC §906.2 requires portable fire extinguishers to be inspected and maintained per NFPA 10. IFC §906.1 specifies placement and quantity requirements.
Required inspection & test frequency
NFPA 10 (2022) inspection, maintenance, and testing intervals for portable fire extinguishers.
| Activity | Frequency | Code reference |
|---|---|---|
| Visual inspection — pressure gauge, tamper indicator, physical damage | Monthly | NFPA 10 §7.2.2 |
| Annual maintenance inspection — full examination, service tag | Annual | NFPA 10 §7.3.1 |
| 6-year internal maintenance — dry chemical, dry powder, halon, clean agent types | Every 6 years | NFPA 10 §7.4.3 |
| Hydrostatic test — stored-pressure dry chemical | Every 12 years | NFPA 10 §8.3.1 |
| Hydrostatic test — CO2 | Every 5 years | NFPA 10 §8.3.1 |
| Hydrostatic test — wet chemical (Class K) | Every 5 years | NFPA 10 §8.3.1 |
| Recharge after use or discharge | Immediately after any use | NFPA 10 §7.5.1 |
What you'll receive from Zion
Every visit ends with documentation your AHJ and insurance carrier will accept on the first review:
- Physical service tag (NFPA 10-compliant) affixed to each extinguisher showing date, technician, and Zion ECR license number
- Inventory report listing every extinguisher at the address by location, type, size, and service status
- Deficiency report for any unit failing inspection, with repair-or-replace recommendation and cost
- Certificate of compliance for the building's extinguisher inventory
- Electronic inspection record in customer portal; available for AHJ review on demand
- 6-year maintenance documentation and hydrostatic test certifications with cylinder manufacturer tracking numbers
Common deficiencies we find
If you're inheriting a building or evaluating an incumbent service provider, these are the issues we see most often — and what they cost to fix when found before an AHJ visit:
- Service tags expired — the single most common AHJ citation; many buildings have extinguishers that were installed and never tagged by a licensed ECR contractor
- Dry-chemical agent compacted or caked — detected only during 6-year internal maintenance; unit reads normal pressure but agent will not flow on discharge
- Missing tamper seals — indicates the pin was pulled at some point; extinguisher may have been partially discharged and not recharged
- Incorrect extinguisher type for hazard class — CO2 extinguisher in a Class A (ordinary combustibles) area where an ABC dry chemical is required; or ABC dry chemical in a kitchen where a wet chemical Class K unit is required by NFPA 10 §5.5.4
- Extinguishers mounted too high — NFPA 10 §6.1.3.1 specifies max handle height of 5 ft (for units ≤40 lbs), commonly exceeded when extinguishers are hung on existing hardware without adjustment
- No extinguisher within required travel distance — NFPA 10 requires no more than 75 ft travel to an extinguisher for Class A hazards; new tenant walls or rearranged occupancy creates violations after renovation
- CO2 extinguisher weight below minimum — CO2 units lose charge through normal diffusion; a unit not weighed annually may appear full but contain insufficient agent
Why Zion for this work
ECR licensed — statewide Texas
Zion ECR #2370364 covers every county in Texas. The technician who tags your extinguisher is an employee, not a day-labor sub-contractor. We maintain your service records and know your building's inventory from year to year.
On-truck recharge capability
Our service trucks carry dry chemical, CO2, and wet chemical recharging equipment plus common-size replacement cylinders. Failed units get recharged or swapped on-site — we don't leave your building partially uncovered while a cylinder goes off for shop service.
Inventory tracking
Every extinguisher in your building is logged by location, type, size, and service history in our system. When the AHJ asks which units were replaced and when, you have an answer in 30 seconds — not a search through paper tags.
Frequently asked questions
Does Texas require annual fire extinguisher inspections?
Yes. Texas Administrative Code Title 28, Chapter 35 requires that portable fire extinguishers in commercial buildings be inspected and maintained annually by a licensed ECR contractor. The AHJ verifies compliance through service tags — a missing or expired tag is a citable violation.
What's the difference between a monthly inspection and an annual inspection?
A monthly inspection (NFPA 10 §7.2) is a visual check: is the unit in its designated place, is the gauge in the operable range, is the tamper seal intact, is there obvious physical damage? It can be performed by trained building staff and does not require a licensed contractor. The annual maintenance inspection (NFPA 10 §7.3) requires a licensed ECR contractor, involves a full mechanical examination of the extinguisher, and results in a service tag affixed to the unit. Staff monthly checks don't replace the annual.
What is the 6-year internal maintenance?
For dry-chemical, dry-powder, halon, and clean-agent stored-pressure extinguishers, NFPA 10 §7.4 requires that every 6 years the unit be emptied, the internal surfaces and valve components inspected, the agent examined for condition, and everything reassembled and recharged. The purpose is to catch agent caking, valve corrosion, and tube blockages that aren't visible externally. A unit last serviced more than 6 years ago with no 6-year record has not been properly maintained.
How do I know if my extinguishers are the right type?
Extinguisher type is matched to the hazard class of the area: Class A (ordinary combustibles), Class B (flammable liquids), Class C (energized electrical), Class D (combustible metals), Class K (cooking oils/fats). NFPA 10 Chapter 5 establishes the selection requirements by hazard class. Common mismatches we find: CO2 extinguishers (Class B/C only) in Class A office areas, and ABC dry chemical in commercial kitchens where Class K wet chemical is required.
Can I buy my own extinguishers and have Zion service them?
Yes. Zion services extinguishers regardless of who supplied them, provided they are listed UL/ULC and appropriate for the hazard. If you've purchased extinguishers independently and need them brought into NFPA 10 compliance (correct placement, initial tag, service record), we can do a first-service inspection and establish the ongoing ITM schedule.
