UNSPSC 39121331: Hazardous location box

An enclosure used in hazardous locations.

UNSPSC 39121331 Hazardous location box (Commodity) describes enclosures and assemblies that state and local governments procure for electrical equipment protection in demanding environments—control panels, switchboards, circuit breaker housings, and junction boxes designed to meet code and operational safety requirements in water and wastewater treatment facilities, utility substations, correctional institutions, and industrial settings. Recent solicitations show procurement focus on fabricated, custom-built control panels for pump stations in multiple configurations (duplex through hexaplex); motor control centers and switchboards for utility and water authority facilities; circuit breaker replacement assemblies and related electrical enclosures; and sealed bids for specialized electrical equipment housings that comply with National Electrical Code, NEMA standards, UL specifications, and Florida or state building codes. Issuing bodies span water and wastewater utilities (Kissimmee Utility Authority, Broward County Public Works and Environmental Services, City of Lavonia Water Treatment), county governments (Hillsborough County, Broward County, Fairfax County), correctional facilities (Texas Department of Criminal Justice, Illinois Department of Corrections), municipalities and utility authorities (Lubbock Power & Light, City of Ocala), and higher-education institutions (University of Mississippi). Repeat buyers include Broward County, which has issued multiple indefinite-quantity procurements for FEMA-compliant water and wastewater control panel fabrication and refurbishment, and Hillsborough County, which has solicited both pump station control panels and motor circuit protectors.

Procurement activity concentrates in Florida and the Southeast, with recent opportunities posted from Kissimmee and Broward County (Florida), Hillsborough County (Florida), Fairfax County and Alexandria (Virginia), and scattered activity in Texas (Lubbock Power & Light, Texas Department of Criminal Justice, City of Lavonia Georgia), Illinois (Department of Corrections), Wisconsin (Portage County), and Mississippi (University of Mississippi). Representative recent work includes the Kissimmee Utility Authority's IFB 17-003-CV for 15 kV circuit breaker replacement at Marydia Substation (response due November 15, 2016; two bids received at $74,710.27 and $77,500), Hillsborough County's ITB 26-00393 for pump station control panels and enclosures over two years at an estimated $3.66 million (response due September 29, 2026; ten bidders submitted with unit prices ranging $21,000–$112,000 per panel), Broward County's indefinite-quantity procurements PNC2132148B3 for fabrication and refurbishment of water and wastewater control panels with $80,000 annual pass-through allowances (response due June 22, 2026), and Fairfax County's IFB 2000004382 for switchgear testing and preventative maintenance on a five-year term (response due June 9, 2026). Set-asides and preferences vary by jurisdiction; Broward County does not apply Office of Economic and Small Business Development set-asides to control panel work, though certified SBEs and CBEs may match the lowest non-certified bid within ten percent and receive award consideration under local preference guidelines. Hillsborough County identified a Tampa-based SLBE-certified electrical supplier for motor circuit protector inventory. Work typically requires UL 508A Certification, Master Electrician licensing or state contractor licensing, comprehensive general liability insurance ($1–2 million per occurrence), compliance with prevailing wage where federally funded or applicable under state law, and factory acceptance testing with documented sign-off before shipment.
