IR Thermography <br /> Amec Foster Wheeler utilized a Fluke TiR infrared (IR) camera to examine building materials for <br /> thermal gradients that could represent areas of possible excess moisture. Accessible building <br /> materials that appeared to be relatively cold in an IR image were assessed directly using a moisture <br /> meter and by manually examining materials. <br /> ' Moisture Testing <br /> Moisture content was measured in remaining gypsum wallboard (GWB) using a direct-reading <br /> moisture meter' and a non-penetrating moisture meter2. Moisture content readings were collected to <br /> identify building materials that contained sufficient moisture to support and amplify mold growth. The <br /> instruments used are designed for quantitative measurement of moisture content in wood, gypsum <br /> wallboard, plaster, and concrete. <br /> Wood with a moisture concentration of 20 percent or greater is considered "wet" and capable of <br /> supporting mold growth. Moisture content in gypsum wallboard is measured on a relative percent <br /> scale using the Delmhorst BD-2100. A moisture content of 0 to 0.4 percent is considered "dry,"0.5 to <br /> 0.9 percent is considered "borderline" and 1.0 percent and greater is considered "excess moisture" <br /> and capable of supporting mold growth. <br /> FINDINGS <br /> Visual Observations <br /> • <br /> Time Observation <br /> 8:39 AM Derrick from ESI, Mel from ESI arrive at 8:55.Also Assistant Chief Brian Burkeen, Mark Hill, <br /> Attorney, Beth Martin, opposing council. <br /> 9:00 Commence visual inspection, representative from newspaper with camera taking pictures. <br /> No mold odor detected on entry into fire station. <br /> 9:05 Attorney for union asked for ladder. Not available from County. <br /> 9:10 Ladder brought in by ESI. <br /> 9:11 Derrick takes photos and begins inspections. <br /> Inspecting furnace,filter photos. <br /> Did not observe SVG,just a little dust on furnace filters and a few spider webs. Dirt in furnace <br /> area. <br /> 9:20 Inspection by Derrick on-going, using flashlight,taking photos in kitchen and living room. <br /> 9:40 Mel brought out IR camera(Fluke model) <br /> 1 Delmhorst BD-2100. <br /> 2 Tramex Digital MRX. <br /> 5 <br /> 18 <br />
