Fungal-Biological Hazard Remediation Protocol-Phase II Irerracon <br />Grand Theater ■ 21 Lamar Street, Paris, Texas <br />February 24, 2011 ■ Terracon Project No. 94117645 <br />remedial work the worker should leave containment as previously described and clean, <br />disinfect and securely bandage the injury prior to returning to the remediation work area. <br />It is the Contractor's responsibility to ensure that his employees are afforded the respiratory <br />protection as required by the OSHA standard for respiratory protection (29 CFR 1910.134, <br />December, 2008) or the respiratory protection requested by the employee. The Contractor <br />shall ensure the workers are instructed and trained in the proper use, maintenance, and <br />care of respiratory protection in accordance with Title 29 CFR 1910.134. It is the <br />contractor's responsibility to ensure that workers on scaffold platforms or working from <br />ladders or other elevated platforms should be safe and secure from slipping or falling. <br />9.0 CLEANING/DECONTAMINATION <br />The gross removal of PRD will consist of pre-wetting the PRD with a quaternary ammonium <br />chloride disinfectant solution to reduce hydrophobicity and mitigate dust generation prior to <br />handling. The PRD will be continuously wetted using an airless spray pump as desiccated <br />layers are uncovered during the removal process. The PRD should not be saturated but <br />lightly misted with the quaternary ammonium chloride disinfectant solution. Examples of <br />approved biocide/disinfectants include Fosters 40/800 (quaternary ammonium chloride), <br />Shockwave0 (quaternary ammonium chloride), or an equivalent product when approved by <br />the MAC prior to application. Material Safety Data Sheets for all chemicals used during the <br />remediation must be maintained onsite by the MRC. <br />PRD will be cleaned from remaining environmental surfaces by mechanical cleaning and <br />decontamination procedures using HEPA vacuuming and wet wiping. After gross removal <br />of PRD, surfaces should be HEPA vacuumed to remove loose materials and provide the first <br />stage of decontamination. The second stage of decontamination and disinfection of the <br />substrate is wet wiping, which will be performed with water amended with an appropriately <br />labeled and EPA registered biocide, and used on non-porous or semi-porous substrates. A <br />wire brush or other abrasive techniques will be required to clean non-porous and semi- <br />porous surfaces. Removal of PRD and fungal growth from the referenced surFaces will <br />continue until no PRD or fungal growth is visible. Stains on the surFace of wood, concrete or <br />other building materials left in place should be lightly sanded or wire brushed to remove the <br />first layer of the substrate. Run off of aqueous cleaning solutions must be controlled and <br />contained within the defined work areas. <br />The environmental surfaces within the containment area, including floors, walls and other <br />environmental surfaces, will be re-cleaned prior to the Post Remedial Verification (PRV). <br />Responsive ■ Resourceful ■ Reliable 4 <br />MAC # 0107/11-10-12 <br />
