Gloves and eye protection should be worn. <br /> o Applicable federal, state and local administrative codes,rules and statutes must be <br /> identified and followed. <br /> • IICRC S520 Condition 2 (settled spores or fungal fragments)—an indoor environment which <br /> is primarily contaminated with settles spores or fungal fragments that were dispersed directly or <br /> indirectly from, and reflective of,the fungal ecology of a Condition 3 area,which may have <br /> traces of actual growth. <br /> o The primary work area is defined as any Condition 3 areas mentioned in the conclusions <br /> above; however,the HVAC duct systems may also require some level of cleaning to <br /> remove settled and airborne fungal material. The surfaces in any Condition 2 areas should <br /> be cleaned and extra focus should be attended to porous items. <br /> o Any content items such as electronics, furniture or personal items will need to be cleaned <br /> by a professional remediation contractor before they are moved to a non-contaminated <br /> area. <br /> o As mentioned above,the HVAC equipment may need to be cleaned and sanitized as part <br /> of this remediation if determined Condition 2 or 3. Heating,ventilation and air- <br /> conditioning systems(HVAC)play an important role(both positive and negative)in <br /> fungal infestation and dissemination as follows: 1)as a dispersal pathway for airborne <br /> fungal spores; and 2)as growth locations for fungi that enter the systems(e.g., drip pans, <br /> chill coils, and ductwork). Any HVAC system remediation should be cleaned by a <br /> NADCA(National Air Duct Cleaning Association)certified duct cleaner. If the interior <br /> of the ductwork contains insulation it will need to be removed and/or replaced. <br /> o Remediation should be conducted by personnel trained on proper clean-up methods, <br /> personal protection, and potential health hazards to comply with requirements of the <br /> OSHA Hazard Communication Standard(29 CFR 1910.1200).Respiratory protection in <br /> accordance with the OSHA respiratory protection standard(29 CFR 1910.134)is <br /> recommended. Gloves and eye protection should be worn. <br /> o Applicable federal, state and local administrative codes,rules and statutes must be <br /> identified and followed. <br /> • IICRC 5520 Condition 1 (normal fungal ecology)—an indoor environment that may have <br /> settled spores, fungal fragments or traces of actual growth whose identity,location, and quantity <br /> is reflective of a normal fungal ecology for a similar indoor environment. <br /> Preparatory Steps (to be performed by the remediation contractor): <br /> o Use blue painter's tape under duct tape to prevent unnecessary damage to walls;use <br /> staples and duct tape and/or spray tack to seal the protective barriers. <br /> o Seal all exterior wall penetrations and window seals in the building with blue painter's <br /> tape to keep outdoor air from being pulled into the building during depressurization <br /> (note: it will be necessary to remove the blue tape to clean under it. Replace with new <br /> tape after cleaning). <br /> o It may be necessary to remove certain content items before the remediation process <br /> begins. <br /> Environmental Solutions Group • 7 Maple Leaf Drive,Ste 104, Greensboro, NC 27410 • 336-373-1538 25 <br /> www.Go-ESG.com <br />
