UNSPSC 41114426 Baroswitch is a Commodity code covering lightning detection, protection, and weather monitoring systems and components that state and local governments procure to safeguard infrastructure and personnel. Recent solicitations show the code encompasses both hardware and installation services — lightning protection system installation at military facilities, lightning detection and severe weather monitoring equipment with preventative maintenance and upgrades, temperature and weather sensor hardware supplied FOB Destination to state agencies, and lightning prediction and detection systems integrated with existing airport and park infrastructure. Issuing bodies range across military departments, county governments, airport authorities, and special districts; the Texas Military Department, Hillsborough County, Texas Water Development Board, Broward County, and the City of Fort Lauderdale have posted opportunities in the past five months. The work reflects a mix of capital installation (comprehensive lightning rod and grounding systems meeting Underwriters Laboratories and National Fire Protection Association standards), recurring maintenance and monitoring services (preventative station maintenance, firmware updates, testing, and commissioning), sole-source vendor relationships for proprietary system compatibility, and commodity procurement of exact specified sensors and components.

Recent activity concentrates in Texas and Florida. The Texas Military Department's IFB for lightning protection system installation at Camp Swift in Bastrop, Texas closed September 26, 2026, with a mandatory pre-bid site visit on September 16; work required two to five years of commercial lightning protection systems installation experience and comprehensive insurance including Commercial General Liability of $1,000,000 per occurrence. Hillsborough County issued a sole-source procurement notice for Earth Networks hardware, software, and maintenance of its lightning detection and severe weather monitoring system, with challenges due September 11, 2026 and an estimated contract value of $47,627.54 over two years. The Texas Water Development Board's IFB for temperature sensors, cables, and mounting equipment specified exact brand names and model numbers under a single-source statutory framework, with bids due August 25, 2026. Broward County and the City of Fort Lauderdale posted an RFI in May 2026 to determine sole-source justification for the Thor Guard, Inc. TG-360 Lightning Prediction and Detection System, which would integrate with and upgrade existing systems at County Parks and Fort Lauderdale-Hollywood International Airport.
