Level One: Clean and isolate active work areas in accordance with Section 3.01. Wet all mold containing materials with an approved biocide solution using equipment capable of providing a fine spray mist, to reduce airborne concentrations when the material is disturbed. Keep all removed material wet enough to prevent release until it can be containerized for disposal. Removal and cleaning: ALL acoustic ceiling tiles, ALL carpet throughout the entire building are to be removed and properly disposed of. Non-Porous Materials - All non-porous surfaces are to be cleaned using a detergent solution or solution of contractor's choice that will re move mold. HEPA vacuums may be used along with the solution for cleaning. All materials need to be dried. Examples of non-porous materials include: Metal Glass Hard plastics Plumbing fixtures All HVAC diffusers are to be removed, thoroughly cleaned (as detailed above) and set aside per Owner s direction to be re-installed later. Semi-Porous (e.g. wood doors, unsealed concrete) All semi-porous surfaces are to be cleaned using a detergent solution or solution of contractor's choice that will remove mold. This solution must be approved by owner. HEPA vacuums may be used along with the solution for cleaning. All materials need to be dried. Examples of semi-porous materials include: Wood Concrete Porous Materials - Remove all porous materials where visible mold growth or evidence of moisture is present. The materials should be removed, bagged and discarded. Examples of porous materials include: Drywall Insulation of all types Carpet (all being removed, regardless of evidence) Acoustic ceiling tiles (all being removed, regardless of evidence) Containers (6 mil polyethylene bags) shall be sealed when full. Bags shall not be overfilled. They should be securely sealed to prevent accidental opening and leakage by tying tops of bags in an overhead knot or by taping in gooseneck fashion. Do not seal bags with wire or cord. Bags shall be decontaminated on exterior surfaces by wet cleaning and HEPA vacuuming. Large components removed intact may be wrapped in 2 layers of 6 mil Polyethylene sheeting secured with tape for transport to the landfill. Mold containing waste with sharp edged components (e.g., nails, screws, metal lath, tin sheeting) will tear the polyethylene bags and sheet and shall be reinforces with extra bags or wrapping. CLEANUP PROCEDURE Remove and containerize all visible accumulations of mold containing material and mold contaminated debris utilizing rubber dust pans, rubber squeegees, HEPA vacuums, etc. Remove all containerized waste from the work area and waste container pass out airlock. Decontaminate all tools and equipment and remove at the appropriate time in the cleaning sequence. Inspect the work area for visible residue. If any accumulation of residue is observed, it will be assumed to be mold and the work area must be re-cleaned. The work area shall be cleaned until it in compliance with criteria agreed upon by the Contractor and Owner prior to initiation of remediation activities. Following the satisfactory completion of clearance criteria remaining barriers may be removed and properly disposed of. A final visual inspection by the Owner shall ensure that no contamination remains in the work area. Unsatisfactory conditions may require additional cleaning and air monitoring (see Section 3.11, Reestablishment of the Work Area). CLEARANCE TESTING Following the completion of cleanup operations, the Remediation Contractor shall notify the Owner (or Industrial Hygiene consultant selected by owner) when the building area is ready for clearance testing. Remediation Contractor will not be responsible for performing clearance testing. The Owner (via contracted Industrial Hygienist) shall arrange for collecting samples. 3.10 DISPOSAL PROCEDURES General: As the work progresses, to prevent exceeding available storage capacity onsite, sealed and labeled containers of mold containing waste shall be removed and stored in the dumpster on-site until it is transported to the prearranged disposal location. All Waste Shipment Records shall be delivered to the Owner. A recommended record keeping format utilizes the Waste Shipment Record (WSR) which includes the names and addresses of the Generator (Owner), Contractor, Transporter, and Disposal Site, the estimated quantity of the mold waste and the type of containers used. Transportation to the Landfill: Once drums, bags and wrapped components have been removed from the work area, they shall be loaded into an enclosed truck or dumpster for transportation. Any debris or residue observed on containers or surfaces outside of the work area resulting from cleanup or disposal activities shall be immediately cleaned up using HEPA filtered vacuum equipment and/or wet methods as appropriate. Large metal dumpsters are sometimes used for mold waste disposal. These should have doors or tops that can be closed and locked to prevent vandalism or other disturbance of the bagged mold debris and wind dispersion of mold fibers. Bags shall be placed, not thrown, into these containers to avoid splitting. Disposal at the Landfill: Upon reaching the landfill, trucks are to approach the dump location as closely as possible for unloading of the mold containing waste. Bags, drums, and components shall be inspected as they are off loaded at the disposal site. Waste containers shall be placed on the ground at the disposal site, not pushed or thrown out of the trucks. Following the removal of all containerized waste, the truck cargo area shall be decontaminated using HEPA vacuums and/or wet methods to meet the no visible residue criteria. 3.11 RE-ESTABLISHMENT OF THE WORK AREA AND SYSTEMS Re-establishment of the work area shall only occur following the completion of cleanup procedures and after clearance criteria have been met and documented to the satisfaction of the Owner. The Contractor and Owner shall visually inspect the work area for any remaining visible residue. Evidence of contamination will necessitate additional cleaning requirements in accordance with Section 3.07. Following satisfactory clearance of the work area, remaining polyethylene barriers may be removed and disposed of as mold contaminated waste. At the discretion of the Contractor, mandatory requirements for personal protective equipment may be waived following the removal of all barriers. Re-secure mounted objects removed from their former positions during area preparation activities. Relocate objects that were removed to temporary locations back to their original positions. Reestablish HVAC, mechanical and electrical systems in proper working order. Remove contaminated HVAC system filters and dispose of as mold contaminated waste. Decontaminate filter assembly using HEPA vacuums and wet cleaning techniques. Install new filters in HVAC systems. Dispose of old filters. Repair all areas of damage that occurred because of remediation activities.
