Fire Protection (United States) — NAICS 922160

1. Overview

Fire protection is one of the few "industries" that is not really a business. Under the North American Industry Classification System (NAICS — the U.S. government's standard code for industries), code 922160 covers government establishments primarily engaged in firefighting and fire prevention, including departments that combine fire protection with ambulance or rescue service [1]. In plain terms: the municipal, county, township, and special-district fire departments — the people who show up when you call 911 for a fire, a car crash, or, most often, a medical emergency.

Because the service is overwhelmingly delivered by governments and by unpaid volunteers, there is no stock you can buy that "is" the fire service. The investable question is different: who gets paid to equip, supply, build, service, insure, and increasingly to litigate around this roughly $79-billion-a-year government function [6]? The answer is a surprisingly deep supply chain — fire-truck makers, sprinkler and alarm firms, life-safety inspection roll-ups, breathing-apparatus and turnout-gear makers, private ambulance and wildfire-aircraft operators, chemical companies carrying multibillion-dollar liabilities, and the municipal-bond market that funds the departments themselves.

• Public-market ways in: apparatus (fire-truck) manufacturers; fire-protection-systems and life-safety-services companies; safety-equipment and detection makers; one small aerial-firefighting operator — plus municipal bonds as a fixed-income route.
• Private ways in: private-equity-backed fire-protection service platforms, privately held equipment makers and EMS/fire contractors, and direct purchases of municipal and fire-district debt.

This primer treats the government service as the demand engine and the private supply chain as the investable surface.

2. What it is and how it's structured

Scope. NAICS 922160 is a "Public Administration" industry: government units primarily engaged in firefighting and fire prevention — including prevention, inspection, public education, rescue, and, where combined with fire protection, ambulance service [1]. Delivery is fragmented and local, spread across roughly 29,000+ fire departments and a workforce of about a million firefighters (career plus volunteer) [3].

Ownership mix.

• Career (paid) departments are a minority by count — on the order of 18% of departments are all-career or mostly-career — but they protect about 70% of the U.S. population because they cover the cities and dense suburbs [3].
• Volunteer and mostly-volunteer departments are the large majority of departments and cover mostly small towns and rural areas; volunteers make up about 65% of all U.S. firefighters [3].
• Structures vary: city departments funded from the general budget, independent special fire districts with their own tax levy, county and township services, and a small number of private contract operators.

What NAICS 922160 excludes (and where those activities sit). This matters, because nearly everything an investor can actually buy shares in lives in the adjacent codes, not in 922160:

• Combined police-and-fire departments → NAICS 922120 (Police Protection) [1].
• Firefighting sold as a commercial service (private wildfire and industrial fire crews) → NAICS 561990 (All Other Support Services) [1].
• Ambulance service without fire protection → NAICS 621910 (Ambulance Services) [1].
• Security-alarm installation and monitoring → NAICS 561621; alarm installation without monitoring → NAICS 238210 [1].
• Fire-sprinkler installation → NAICS 238220 [1].
• Fire-extinguisher repair (without installation) → NAICS 811310 [1].
• Fire-detection and alarm manufacturing → NAICS 334290; fire trucks, pumps, and other hardware sit in their own manufacturing codes [1].

The government code itself is government-owned by definition; the private ecosystem around it ranges from small owner-operated shops to national and international platforms.

3. How big it is

Our federal ground-truth note. Histometrics has no ingested Census/SBA business statistics for NAICS 922160 — and that absence is itself the story. The standard federal business datasets (County Business Patterns, the nonemployer series, SBA small-business tallies) count private employer firms and self-employed workers; County Business Patterns explicitly excludes most government establishments [2]. Because 922160 is a government sector staffed largely by volunteers, those datasets structurally undercount it toward zero. The industry's real size shows up in government-finance and fire-service statistics instead:

• Government spending: state and local governments spent about $79.2 billion on fire protection in 2024 (U.S. Bureau of Economic Analysis) [6]. Inflation-adjusted local fire-protection spending roughly tripled between 1980 and 2019 [3]. Federal wildland-fire agencies spend billions more on suppression in a bad season, tracked separately by the National Interagency Fire Center [9].
• Departments and people: roughly 29,000+ fire departments and about 1.0–1.05 million firefighters (career plus volunteer), per NFPA's most recent U.S. Fire Department Profile [3]. (NFPA = National Fire Protection Association, the main U.S. fire-data and codes body.)
• Unpriced volunteer labor: NFPA values donated volunteer-firefighter time at roughly $140 billion a year [7] — a "cost" no budget records and no company books. This is the single biggest reason the sector looks small in dollar terms but is enormous in real terms.
• Workload: U.S. fire departments now field on the order of 35 million calls a year, of which only about 4% are actual fires and roughly two-thirds are medical/rescue [4]. (The U.S. Fire Administration's narrower NFIRS-reported base logged about 27 million incident runs in 2020, with EMS and rescue at 64% and fire at about 4% [4].) In 2022 there were about 1.5 million reported fires, causing roughly 3,790 civilian deaths and about $18 billion in direct property damage [5]; the U.S. Fire Administration estimated about 111,900 nonresidential building fires in 2024 [8].

The headline: demand is huge and growing, but it is a public cost center, not a profit pool. The profit pool is in the supply chain.

4. The investable universe

There is no clean U.S.-listed pure-play that "is" the fire service or even the full commercial fire-protection market. The tables below map how public and private capital actually touches the sector. Tickers and scale are for orientation, not recommendations. Where a company is diversified, segment revenue is not fire-only or U.S.-only unless noted.

Public companies

Major private owners and platforms

The buyers — fire departments — are governments, so the closest thing to owning the demand side is holding municipal, county, or special-fire-district bonds. Private equity is concentrated in the services layer, where it is building national inspection/testing/monitoring platforms:

• Pye-Barker Fire & Safety — extinguishers, suppression, alarms, sprinklers, inspection, monitoring, code compliance. Altas Partners is majority owner; Leonard Green & Partners retains a meaningful stake, with Abu Dhabi Investment Authority and GIC (Singapore's sovereign wealth fund) as minority holders [24].
• Summit Companies — integrated detection, suppression, life-safety. BDT & MSD Partners agreed in 2025 to acquire a majority stake from BlackRock Long Term Private Capital; management retained equity [25].
• Sciens Building Solutions — fire detection, security, design, installation, maintenance. Carlyle took a majority position in 2021 [26].
• Fortis Fire & Safety — commercial fire and life-safety platform backed by Imperial Capital [27].
• Encore Fire Protection — installs/inspects/maintains alarms, extinguishers, sprinklers. Permira acquired Encore in 2025 for $1.8 billion (including debt) from Levine Leichtman Capital Partners [28].
• KiddeFenwal — industrial/commercial suppression and detection; Pacific Avenue Capital Partners acquired substantially all assets in 2024 (part of Carrier's Fire & Security exit) [29].
• Global Medical Response / AMR (KKR-owned) — largest U.S. medical-transport operator; consolidated the private fire/EMS contracting layer, folding in Rural/Metro.

Family-owned and local operators remain important, especially in inspection, maintenance, emergency repair, and municipal work.

5. How the money works

Because the service itself is a government cost center, "how owners make money" means how each layer of the supply chain earns, and each layer has different economics:

• Fire-apparatus makers (REV, Oshkosh/Pierce, Rosenbauer). A long-cycle, backlog-driven, book-to-bill business, closer to specialty capital goods than consumer manufacturing. A modern pumper now costs around $1 million and a ladder truck around $2 million, up from roughly half that a decade ago, with order-to-delivery lead times stretched to two to four years [11]. The metrics that matter are backlog, order intake, unit pricing, and gross margin, plus a steady aftermarket on a 20–30-year truck life.
• Fire-protection systems and services (Johnson Controls/Tyco, APi Group, Honeywell). The money is in code-mandated installation plus recurring inspection, testing, and monitoring on a large installed base. Service and monitoring revenue is higher-margin and stickier than one-time equipment sales — the classic "installed base + service contract" annuity. Code and insurance requirements support recurring inspection demand, though the precise legal trigger varies by jurisdiction [13].
• Safety equipment and detection (MSA Safety, Resideo, ADT). Product sales into a replacement cycle (breathing apparatus, turnout gear, detectors) plus, for the monitoring names, recurring subscription revenue.
• Private fire/EMS contractors (Global Medical Response/AMR). These earn through municipal service contracts and fee-for-service transport billing; margins are thin and heavily exposed to payer reimbursement (Medicare/Medicaid and insurers).
• Aerial firefighting (Bridger Aerospace). Largely government standby-plus-flight-hour contracts — a daily availability rate plus more per hour flown. Drivers are guaranteed flight days, fleet utilization, and contract renewals [22].
• The government "owner." A fire department does not earn a return; it is funded by local property taxes, special-district levies, bond issues, some EMS transport billing, and federal grants (see §7). For a bond investor the relevant metrics are the tax base, the levy, pension load, and coverage — not profit.

For the private service layer, the most useful investor metrics are recurring-service mix, renewal/retention rates, route density, technician productivity and turnover, project backlog and gross margin, working-capital and cash conversion, customer concentration, warranty/liability exposure, and acquisition leverage [13]. The strategic point: durable, recurring profit sits in service (inspection/testing/monitoring) and aftermarket; cyclical, backlog-driven profit sits in apparatus and large installation projects.

6. What drives demand

• Codes and insurance. Building and fire codes force periodic inspection, testing, and maintenance, turning a sprinkler or alarm system into an annuity regardless of the fire count [13]. A community's ISO Public Protection Classification (a 1–10 fire-protection score used by property insurers) also ties fire-service quality to premiums, giving towns a financial reason to fund departments and equipment.
• Aging systems and building stock. More square footage plus aging alarm, sprinkler, suppression, and extinguisher systems expand the installed base that must be serviced or retrofitted.
• Critical-facility construction. New data centers, advanced manufacturing, warehouses, and healthcare facilities carry heavy fire-protection content [13][14].
• The aging population and the shift to medical calls. The fire service has quietly become an emergency-medical service — most calls are now medical, not fires [4]. An older population means more EMS volume, the steadiest structural driver.
• Wildfire and the wildland-urban interface. Longer fire seasons, drier fuels, and more homes built into fire-prone landscapes drive suppression spending and demand for aircraft, retardant, and defensible-space work [9][22]. This is the fastest-growing structural theme.
• The apparatus replacement cycle. Trucks last decades, then must be replaced; a wave of aging apparatus plus multiyear lead times has created a large, visible backlog [10][11].
• Municipal budgets and grants. Most spending ultimately rides on local property-tax revenue; FEMA grant programs (see §7) support apparatus, equipment, training, and staffing for eligible departments [33].

Forward-looking judgment: inspection, testing, maintenance, monitoring, and compliance work should be more defensive than new construction; large installation and retrofit projects remain more exposed to commercial-construction cycles, interest rates, and permitting delays.

7. Regulation

Fire protection is unusual because the industry is also a regulator — departments enforce fire codes. The sector itself is shaped by:

• NFPA consensus codes and standards. NFPA writes the model codes adopted (in whole or part) by most states and cities — e.g., NFPA 13 (sprinkler design), NFPA 1 (fire code), NFPA 25 (inspection, testing, and maintenance of water-based systems) [32], and the staffing/response-time standards NFPA 1710 (career) and 1720 (volunteer). These codes create much of the sprinkler, detection, and apparatus demand.
• OSHA (the federal Occupational Safety and Health Administration). Its Subpart L fire-protection rules cover portable extinguishers, automatic sprinklers, fixed extinguishing systems, fire-detection systems, and employee alarms, and require detection systems to be maintained, operable, and tested by trained personnel; OSHA also sets firefighter safety rules such as respiratory protection and "two-in/two-out" [30].
• Model codes and local adoption. The International Code Council (ICC) publishes model building and fire codes, but a model code is enforceable only after a state or local authority having jurisdiction (AHJ) adopts it, and jurisdictions may amend it [31]. Licensing, permitting, procurement, and inspection enforcement vary materially by state and locality — regulation supports demand but also creates geographic complexity and compliance risk.
• Federal grants. FEMA's AFG (Assistance to Firefighters Grants) and SAFER (Staffing for Adequate Fire and Emergency Response) help departments — especially volunteer and rural ones — buy apparatus and hire staff [33]. Their annual funding and reauthorization directly move the low end of the equipment and staffing market.
• EPA and PFAS rules. The phase-out of PFAS ("forever chemicals," per- and polyfluoroalkyl substances) in firefighting foam and turnout gear is reshaping both product demand and liability (see §9).
• FAA rules govern aerial firefighting; labor law and IAFF (International Association of Fire Fighters) collective bargaining shape career-department cost structures.

8. Competitive dynamics and consolidation

• Apparatus is a tight oligopoly. Three manufacturers — REV Group, Oshkosh (Pierce), and Rosenbauer — hold an estimated 70–80% of the U.S. fire-truck market, with REV alone around a third [10][11]. Years of roll-ups (REV absorbing E-ONE, KME, Ferrara, Spartan and others) drove that concentration.
• That concentration is now under political scrutiny. A September 2025 Senate subcommittee hearing, "Sounding the Alarm: America's Fire Apparatus Crisis," pressed the three makers on two-to-four-year delays and roughly doubled prices, and Senators Warren and Banks opened a bipartisan investigation into private equity's role in fire-truck manufacturing; the makers argue the backlog reflects demand and supply-chain constraints, not strategy [11]. The outcome — potential antitrust, procurement, or pricing pressure — is a live wildcard for the apparatus names.
• Services is highly fragmented and consolidating fast. APi describes competitors ranging from small local owner-operators to large national and international firms, competing on price, service quality, technical expertise, response time, reputation, and relationships, with limited barriers to entry in some lines [13]. Private-equity platforms (Pye-Barker, Summit, Sciens, Fortis, Encore) are using acquisitions to build geographic density, purchasing scale, centralized administration, and cross-selling; APi's own CertaSite acquisition (completed 2026) is a recent public example [13]. The durable advantages tend to be a large installed base and inspection history, qualified/certified technicians, route density, relationships with insurers and local AHJs, national-account coverage, and monitoring/compliance software.
• Private fire/EMS consolidated around Global Medical Response (which folded in Rural/Metro), leaving few independent private fire contractors.

Forward-looking judgment: consolidation should continue, but value creation depends on technician retention, service quality, pricing discipline, integration, and avoiding excessive acquisition leverage.

9. Risks

• PFAS/AFFF liability — the big one. AFFF (aqueous film-forming foam) used for decades in firefighting contains PFAS. Chemical makers have agreed to enormous settlements with public water systems — 3M for up to ~$10.3 billion and DuPont/Chemours/Corteva for ~$1.185 billion — while a separate mass of personal-injury lawsuits (roughly 10,000-plus in the federal MDL) from firefighters and residents is still being litigated [23]. Firefighter turnout-gear PFAS is a further, growing front. This is a liability overhang on the chemical names and a replacement-demand tailwind for foam and gear.
• Government-budget dependence. Demand rides on property-tax revenue and municipal fiscal health; downturns, pension costs, and tax-cap politics squeeze fire budgets and delay orders.
• Volunteer-staffing crisis. Volunteer numbers have fallen for years even as call volume rises [3], pushing communities toward costlier career departments and straining rural coverage; private contractors, in turn, depend on scarce qualified technicians.
• Apparatus cost inflation and delays strain municipal buyers and invite the regulatory scrutiny above [11].
• Project execution. Fixed-price installation contracts are exposed to material inflation, labor shortages, delays, and cost overruns [13].
• Quality and liability. A failed alarm, sprinkler, suppression system, or inspection can cause property damage, injury, litigation, and reputational loss.
• Wildfire catastrophe risk cuts both ways — it drives spending and aerial-firefighting demand [9][22] but exposes operators to weather-dependent, seasonal, safety-critical revenue.
• Roll-up and leverage risk. Acquisitions can destroy value through overpayment, weak integration, customer attrition, or excessive debt; technology/cyber risk rises as alarms and monitoring go connected.
• EMS reimbursement pressure squeezes private transport margins.

10. How to invest, and the outlook

Public-market routes.

• Fire-protection systems and services: APi Group (APG) is the closest listed service proxy; Johnson Controls (JCI) and Honeywell (HON) offer larger but diluted exposure — the recurring, code-driven, service-annuity angle [13][14][16].
• Fire apparatus: Oshkosh (OSK), REV Group (REV), Rosenbauer (Vienna: ROS) — a concentrated, backlog-rich, cyclical bet on the replacement cycle and municipal budgets, with regulatory overhang [10][11][12].
• Safety equipment / detection / distribution: MSA Safety (MSA), Resideo (REZI), ADT, Core & Main (CNM) — supplier and adjacent exposures; treat Carrier (CARR) as a negative comparator after its 2024 Fire & Security exit [17][18][19][20][21].
• Aerial wildfire suppression: Bridger Aerospace (BAER) — a small, high-beta, wildfire-season play [22].
• Municipal bonds: general-obligation, special-fire-district, and special-assessment bonds fund the departments themselves — the fixed-income way to lend into the demand side. Analyze the issuer's tax base, staffing/pension load, apparatus-replacement plan, interlocal agreements, debt burden, and grant dependence.
• Liability-exposed chemical names (3M, DuPont/Chemours/Corteva) are an AFFF/PFAS risk story, not a fire-service growth play [23].

A discipline for public names: segment revenue is not fire-protection revenue unless the company discloses it separately, so weigh valuation against the quality and durability of the specific exposure, not the total revenue of a diversified conglomerate.

Private routes. Private-equity-backed fire-protection service platforms (inspection/testing/monitoring), privately held equipment makers, private EMS/fire contractors, and direct purchase of municipal and fire-district debt. Diligence should emphasize service-contract renewal, customer concentration, inspection compliance and certifications, technician retention, route density, project backlog, working capital, warranty/claims history, acquisition integration, and debt terms — alongside the usual private-market caveats of limited liquidity, fees, and thinner disclosure.

Outlook (forward-looking judgment, not established fact). The base case is durable but moderate growth: an apparatus replacement supercycle slowly working down multiyear backlogs; steady growth in code-driven inspection/service revenue; rising wildfire spending favoring aircraft, retardant, and defensible-space work; aging-population EMS demand as the most durable driver; and a PFAS transition that is simultaneously a liability drag on chemical makers and a replacement tailwind for foam and gear. The main swing factors are federal grant funding (AFG/SAFER levels), municipal fiscal health, and the regulatory/antitrust outcome of the fire-truck pricing investigation. None of this makes fire protection a high-growth sector — it is a defensive, essential-service demand base whose value accrues to the companies that equip and service it, especially those combining dense local service networks with strong compliance, people management, and disciplined capital allocation.
