UNSPSC 81141802: Industrial hygiene or ventilation

UNSPSC 81141802 Industrial hygiene or ventilation is a Commodity code under which state and local governments procure on-call industrial hygiene testing, air quality monitoring, hazard assessment, and facility maintenance services supporting compliance with occupational safety and environmental regulations. The code captures both standalone industrial hygiene consulting and embedded hygiene services within larger facilities-management scopes—ranging from air quality assessments at correctional facilities and state office buildings to MEP and fire protection maintenance serving IT infrastructure at airports and detention centers where ventilation and hazard control are operational imperatives.

Issuing bodies span state departments (California Department of Transportation, California Department of Water Resources, California Department of Corrections and Rehabilitation, Texas Department of Transportation, Washington Department of Commerce), county governments (Volusia County, Galveston County, Williamson County), cities (Phoenix, Atlanta, Detroit, Salt Lake City, Columbus), universities (Texas State University), transit authorities (Atlanta Department of Aviation at Hartsfield-Jackson), and independent school districts (Salt Lake City School District). State agencies and large municipal departments dominate the activity, with Atlanta Department of Aviation appearing multiple times for maintenance of MEP systems supporting IT infrastructure. Representative recent opportunities include the California Department of Transportation's restricted small-business IFPQ for statewide industrial hygiene and laboratory analysis services at materials-testing facilities (quote deadline June 23, 2026), the California Department of Corrections and Rehabilitation's IFB for industrial hygiene and laboratory analysis services across correctional facilities statewide (proposals due June 9, 2026), the City of Detroit's RFP for HVAC, plumbing, electrical, and fire protection maintenance at the Detroit Detention Center with 24/7 emergency response and criminal-justice background-clearance requirements (proposals due October 27, 2026), and the City of Atlanta Department of Aviation's two-step prequalification and IFB process for MEP and fire protection maintenance supporting IT infrastructure across terminal complexes and support facilities at Hartsfield-Jackson (prequalification conference July 22, 2026; questions due July 31, 2026). Geographic activity concentrates in California (state agencies and utilities), Georgia (Atlanta airport and municipal facilities), Michigan (state and county projects), and Texas (state transportation and municipal departments), with sporadic activity across Washington, Florida, and the upper Midwest. The code shows material recent activity tied to facilities-operations contracts where industrial hygiene, ventilation maintenance, and emergency response are mission-critical or compliance-driven requirements.
