UNSPSC 46191509: Toxic vapor detector

A device that detects and measures the toxic vapor which has not so high of boiling point and is relatively easy to liquefied and warn when it reached the risky level.

UNSPSC 46191509 Toxic vapor detector is a Commodity code that covers gas detection equipment and systems for industrial and municipal applications, including hydrogen sulfide (H2S) detection units, primary area gas detection control panels, and associated instrumentation and monitoring systems deployed across water treatment, wastewater, and oil and gas operations. State and local buyers under this code include regional water authorities, state energy agencies, and special-purpose districts managing critical infrastructure where toxic vapor hazards require continuous detection and monitoring. The work spans equipment procurement, system installation, integration with existing control systems such as SCADA platforms, commissioning, operator training, and warranty support.

Activity under this code appears primarily in the Upper Midwest and Texas. The Great Lakes Water Authority (GLWA) issued an IFB in March 2026 for a Primary Area Gas Detection System Upgrade and Switchgear replacement at the Water Recovery Facility in Wayne County, Michigan, with responses due April 27, 2026, including replacement of detection equipment across multiple scum buildings and pump stations, integration into the facility's Ovation control system, and a Not to Exceed price with a Provisional Allowance of $425,000. The Texas General Land Office issued an RFQ in April 2026 for high hydrogen sulfide well plugging and related services, reflecting state procurement of H2S detection and safety equipment for oil and gas asset management across the state, with OSHA H2S certification and relevant safety training required of contractors. Both solicitations emphasize compliance with diversity and small-business set-aside programs, including HUB Zone, ESBD, MBE, WBE, and DBE designations where applicable.
