UNSPSC 41114426 Baroswitch, a Commodity code, covers lightning detection and protection equipment and related systems that state and local governments procure to safeguard facilities, critical infrastructure, and personnel. Recent solicitations show state and local agencies buying lightning prediction and detection systems for airports and parks, weather observation equipment for transportation operations, and lightning protection installations at courthouse facilities. The work ranges from integration of specialized detection hardware (such as the Thor Guard TG-360 system) to comprehensive lightning protection system design and installation complying with NFPA 780, UL, and electrical code standards. Issuing bodies include county purchasing departments, state transportation agencies, and county facility management offices—primarily facilities, public works, and infrastructure protection functions rather than a single dominant buyer type.
