NIGP 22020: Hazardous Environment Detection and Measuring Equipment

NIGP 22020 Hazardous Environment Detection and Measuring Equipment, an Item code, encompasses sealed detection equipment, sensors, calibration services, and maintenance contracts that state and local governments procure to monitor atmospheric and chemical hazards across fire departments, transit authorities, environmental compliance facilities, and emergency response operations. Recent solicitations show state and local buyers purchasing methane detection systems with associated calibration and repair services, chemical and biological hazard detection meters with annual maintenance and preventive service contracts, hydrogen sulfide well monitoring equipment for oil and gas operations, and gas detection sensors with replacement parts and sustainment services.

State departments, county governments, cities, transit authorities, and special-purpose districts all solicit under this code. The Orange County Transportation Authority (California) issued IFB 250322 on June 4, 2026 for methane detection system service and maintenance across five transit facilities, with bids due June 1, 2026 and an estimated contract value of $260,000 over four years; the City of Phoenix Fire Department solicited IFB 26-0111 for hazardous detection equipment, accessories, and preventive maintenance services commencing June 1, 2026; and the Texas Facilities Commission issued RFP 0007615 on May 28, 2026 for remediation and restoration services including hazard detection and testing across multiple state-owned facilities throughout Texas. The Texas General Land Office issued RFQ 455-26-1020 for high hydrogen sulfide well services, and Collier County, Florida issued a Notice of Intent to single-source gas detection and air sampling equipment from TriNova, Inc. Recent activity concentrates in California, Texas, Florida, Arizona, and Ohio, with activity also present in Washington state through Sourcewell's cooperative procurement for law enforcement equipment. Most solicitations impose prevailing wage requirements, compliance certifications (IICRC, OSHA H2S, EPA Lead-Safe, NADCA, TDLR mold licensing), and disadvantaged business enterprise or HUB subcontracting plan obligations where federal funds or state set-aside policies apply.
