Health Risk Assessment of Building 801 Rev_Redacted.pdf

This document is a memorandum from the 179th Cyberspace Wing (179 MDG/SGPB) at Mansfield Air National Guard Base in Ohio, dated May 28, 2026, reporting on a health risk assessment conducted for Building 801 following reports of rodent infestation.

The assessment identified rodent droppings in multiple areas including the kitchen, breakroom, cubicle offices, SIPR room, vehicle maintenance area, and services cage. Visual evidence under blacklight confirmed contamination on breakroom countertops and drawers, with a bucket trap yielding visible mice inside. The memorandum details health hazards associated with rodent infestations, specifically highlighting Hantavirus transmission through dried droppings, urine, and saliva that can cause flu-like illness progressing to respiratory failure if untreated. The document recommends hiring a State of Ohio-licensed pest management professional to conduct remediation activities including inspection of walls and HVAC systems, sealing entry points, eliminating active mice, removing droppings and nests, disinfecting contaminated areas, replacing materials as needed, and performing follow-up monitoring. Until professional cleaning is completed, Building 801 personnel are prohibited from eating, drinking, or preparing food in the breakroom. All workers must be informed of the assessment results and the information must be posted on the safety bulletin board with all employees briefed accordingly. Attachment 1 contains photographs documenting the contamination in various locations throughout the building.
