UNSPSC 46191622: Fire extinguishing ball or patch

A passive fire suppression or extinguishing device consisting of a hard foam shell or ball wrapped in fuses that lead to a small black powder charge within. The ball bursts shortly after contact with flame at a specific temperature, dispersing a cloud of ABC dry chemical powder which extinguishes the fire. The coverage area is about 5 m2 (54 sq ft). One benefit of this type is that it may be used for passive suppression. The ball can be placed in a fire-prone area and will deploy automatically if a fire develops, being triggered by heat.

It may also be manually operated by rolling or tossing into a fire. Most modern extinguishers of this type are designed to make a loud noise upon deployment.

UNSPSC 46191622 Fire extinguishing ball or patch is a Commodity code that captures a narrow range of specialized fire safety hardware, yet state and local procurement activity under this code reflects demand for comprehensive portable fire extinguisher and fire suppression system services — inspections, maintenance, testing, recharging, hydrostatic certification, repairs, and equipment replacement. The code's name does not align well with the actual solicitations posted; the recent work being bought is anchored in portable extinguisher servicing compliance with NFPA 10 standards and fire suppression system maintenance across educational facilities, municipal buildings, airports, transit hubs, and public safety infrastructure.

State and local issuers soliciting under this code span school districts, counties, cities, transit authorities, and independent public authorities. The geographic spread includes activity in Texas (Texas Department of Public Safety, Harlingen Consolidated ISD), Florida (Hillsborough County, Pinellas County, Brevard County, Greater Orlando Aviation Authority, City of Tallahassee), Georgia (Cobb County School District, Bibb County School District, Rockdale County, City of South Fulton, Kennesaw State University), Colorado (Boulder County Housing Authority), Wisconsin (Waukesha County), California (City of Palo Alto, Orange County Transportation Authority), Washington D.C. (Events DC), Connecticut (City of New Haven Board of Education), and scattered other jurisdictions. The coding concentration suggests portable extinguisher work dominates the activity. Representative recent opportunities include the Texas Department of Public Safety's IFB for Irving Fire Extinguisher Maintenance Services (due July 30, 2026) covering annual inspections, recharging, and hydrostatic testing of ABC, CO2, and Halon extinguishers at a single facility under NFPA 10 compliance; the Hillsborough County Board of County Commissioners' ITB for Janitorial and Operational Supplies (due July 24, 2026) estimated at $765,679.84 annually and tagged to fire rescue operations across 47 stations; the City of Palo Alto's IFB for Automatic Fire Extinguishing System Inspection, Testing, and Repair (due March 23, 2026) covering sprinkler and standpipe systems at 33 municipal facilities under a three-year contract estimated at $500,000; and the Cobb County School District's RFP P26108 for Fire Alarm, Sprinkler, and Fire Suppression Inspection Services (due April 23, 2026) with an estimated annual value of $535,000 across 112 school sites. Activity is active and ongoing across multiple tiers of government.
