QA Attach 1 IH REPORT 2018_Redacted.pdf

This document is a DFAS Cleveland Safety Office Industrial Hygiene Report dated March 23, 2018, documenting environmental testing results for indoor air quality (IAQ) at the DFAS facility in Cleveland, Ohio.

The report presents comprehensive IAQ screening data collected on February 27 and March 1, 2018, across multiple floors and the sub-basement training room. Testing parameters included temperature, relative humidity, carbon dioxide (CO2), carbon monoxide (CO), airborne particulate matter, airborne fibers, and microbial spore sampling. Results indicate temperature readings ranged from 72.1 to 77.6 degrees Fahrenheit, relative humidity from 24.2 to 26.1 percent, CO2 from 610 to 950 ppm (below the 1,000 ppm industry standard), and CO from 0.0 to 2.1 ppm (well below EPA guidelines). Airborne particulate concentrations indoors ranged from 380 to 2,400 particles per cubic centimeter, significantly lower than outdoor readings. Airborne fiber sampling showed levels below the asbestos standard of 0.01 fibers per cubic centimeter. Microbial air sampling detected total spore counts lower indoors than outdoors, with identified species including Ascospores, Aspergillus/Penicillium, Basidiospores, and Cladosporium. Visual inspection detected no musty odors, moisture staining, or mold growth. The report concludes that no actions are recommended for carbon dioxide, carbon monoxide, ambient particulate, fibers, or microbial IAQ parameters, with minor recommendations regarding relative humidity adjustment during winter months at the facility's discretion.
