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