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 />individuals enter the vacant building during the duration of the fungal remediation <br />project (Rule § 295.322, Minimum Work Practices and Procedures for Mold <br />Remediation: (d) Containment is not required if only persons who are licensed or <br />registered under this subchapter occupy the building in which the remediation takes <br />place at any time between the start-date and stop-date for the project). <br />b) The remedial work areas will have a minimum of four (4) air changes per hour and <br />will be operated continuously for the duration of the project. The duration of the <br />Fungal-Biological Hazard Remediation project for the purposes of this requirement <br />will be considered from the time containment is established through the time <br />acceptable post remediation clearance results are provided by the Mold Assessment <br />Consultant (MAC). The containment/critical barriers must remain in place until <br />interim written notification of post remediation clearance has been received from the <br />MAC. The contained works will be exhausted to the outdoor environment and not <br />operated under recirculation mode unless the MAC has given approval of short-term <br />recirculation due to building security issues or extended worker absence. Prior to <br />Final Clearance air sample collection the contained work areas will have been <br />operating under exhaust for a minimum of 72 hours. <br />7.0 VENTILATION <br />a) The Phase II remediation work area will be ventilated with the previously established <br />ventilation system as defined for the ACM-LBP abatement as referenced in Scope of <br />Work for Hazardous Materials Abatement, Terracon Project No. 94107645, June 4, <br />2012. Containment/critical barriers must remain in place until interim written <br />notification of post remediation clearance has been received from the MAC. <br />b) The Phase II containment must be maintained at a negative pressure differential of 5 <br />Pascal, or, 0.02 inches of water, with HEPA filtered negative air machines (NAMS) <br />that are exhausted to the immediate outdoor environment. The containment should <br />have a minimum of four (4) air changes per hour and shall be operated continuously <br />for the duration of the project. The negative pressure differential will be continuously <br />monitored with a manometer. The containment/critical barriers must remain in place <br />until interim written notification of post remediation clearance has been received from <br />the MAC. <br />8.0 PPE DURING FUNGAL REMEDIATION <br />Workers will wear personal protective equipment consisting of, at a minimum, full face N-100 <br />respirators, disposable heavy duty work gloves and full body disposable coveralls while <br />performing remedial work.
