Fungal-Biological Hazard Remediation Protocol Irerracon Grand Theater ® 21 Lamar Street, Paris, Texas April 11, 2011 a Terracon Project No. 94117645 clothing worn by remediation workers in the containment will be HEPA vacuumed prior to exit through the two-stage decontamination unit. Except for the doorway and the make-up air provision for the enclosure, the worker decontamination system shall be sealed against leakage of air. All personnel must enter and exit the containment area through the decontamination area. No contaminated individuals or items shall enter the clean room. 6.0 CONTAINMENT/CRITICAL BARRIERS a) The first floor lobby will have the majority of the required critical barriers in place from the previous ACM-LBP abatement as referenced in Scope of Work for Hazardous Materials Abatement, Terracon Project No. 94107645. The TMARR stipulates that a vacant building with controlled access does not require negatively pressurized, contained work areas, if only licensed individuals enter the vacant building during the duration of the fungal remediation project (Rule § 295.322, Minimum Work Practices and Procedures for Mold Remediation: (d) Containment is not required if only persons who are licensed or registered under this subchapter occupy the building in which the remediation takes place at any time between the start-date and stop-date for the project). The polyethylene sheeting on the ceiling of the first floor lobby will be removed to provide access to the wood ceiling deck for decontamination. A critical barrier will be installed at the second floor east demarcation wall from floor level to the ceiling deck prior to beginning any remedial work on the wood ceiling deck. b) The second floor remediation work area will be isolated from the adjacent, attached building by a double layer of six (6) millimeter polyethylene sheeting creating a containment that will be negatively pressurized. The openings between the contained areas and adjacent areas, including but not limited to doorways, corridor entrances, ventilation openings (both supply air and return air), drains, ducts and wall penetrations shall be sealed with a double layer of six (6) mil polyethylene sheeting. The penetrations that could permit air infiltration or air leaks through the barrier shall be sealed, with exceptions of the make-up air and the entry and exit. A two-stage, dry decontamination unit shall provide entrance to the containment work areas as previously described. The containment area must be maintained at a negative pressure differential as described in Section 7.0. The containment should have a minimum of four (4) air changes per hour and shall be operated continuously for the duration of the project. The duration of the Fungal-Biological Hazard Remediation project for the purposes of this requirement shall be considered from the time a containment area is established through the time acceptable post remediation clearance results are provided by the Mold Assessment Consultant (MAC). The containment/critical barriers must remain in place until interim written notification of post remediation clearance has been received from the MAC. n Reliable MAC r 0107/11-10-12 ~150
