- Description
- Create service openings in the system as necessary in order to accommodate cleaning of otherwise inaccessible areas. Mechanically clean all duct systems to remove all visible contaminants, such that the systems are capable of passing Cleaning Verification Testings (see NADCA Standards). Health and Safety Safety Standards: Cleaning contractors shall comply with all appli cable federal, state, and local requirements for protecting the safety of the contractors' employees, building occupants, and the environment. In particular, all applicable standards of the Occupational Safety and Health Administration (OSHA) shall be fol lowed when working in accordance with this specification. Occupant Safety: No processes or materials shall be employed in such a manner that they will introduce additional hazards into occupied spaces. Disposal of Debris. All Debris removed from the HVAC System shall be disposed of in accordance with applicable federal, state and local requirements. Mechanical Cleaning Methodology Source Removal Cleaning Methods: The HVAC system shall be cleaned using Source Removal mechanical cleaning methods designed t o extract contaminants from within the HVAC system and safely remove contaminants from the facility. It is the contractors responsibility to select Source Removal methods which will render the HVAC system Visibly Clean and capable of passing cleaning ver ification methods (See applicable NADCA Standards) and other specified tests, in accordance with all general requirements. No cleaning method, or combination of methods, shall be used which could potentially damage components of the HVAC system or negativ ely alter the integrity of the system. All methods used shall incorporate the use of vacuum collection devices that are operated continuously during cleaning. A vacuum device shall be connected to the downstream end of the section being cleaned through a predetermined opening. The vacuum collection device must be of sufficient power to render all areas being cleaned under negative pressure, such that containment of debris and the protection of the indoor environment is assured. All vacuum devices exhausti ng air inside the building shall be equipped with HEPA filters (minimum efficiency), including hand-held vacuums and wet-vacuums. All vacuum devices exhausting air outside the facility shall be equipped with Particulate Collection including adequate filtra tion to contain Debris removed from the HVAC system. Such devices shall exhaust in a manner that will not allow contaminants to re-enter the facility. Release of debris outdoors must not violate any outdoor environmental standards, codes or regulations. A ll methods require mechanical agitation devices to dislodge debris adhered to interior HVAC system surfaces, such that debris may be safely conveyed to vacuum collection devices. Acceptable methods will include those which will not potentially damage the integrity of the ductwork, nor damage porous surface materials such as liners inside the ductwork or system components. Cleaning of coils: Any cleaning method may be used which will render the Coil Visibly Clean and capable of passing Coil Cleaning Verification (see applicable NADCA Standards). Coil drain pans shall be subject to Non-Porous Surfaces Cleaning Verification. The drain for the condensate drain pan shall be operational. Cleaning methods shall not cause any appreciable damage to, displacement of, inhibit heat transfer, or erosion of the coil surface or fins, and shall conform to coil manufacturer recommendation s when available. Coils shall be thoroughly rinsed with clean water to remove any latent residues. Biocidal Agents and Coatings:Biocidal agents shall only be applied if active fungal growth is reasonably suspected, or where unacceptable levels of fungal contamination have been verified through testing. Application of any biocidal agents used to control the growth of fungal or bacteriological contaminants shall be perf ormed after the removal of surface deposits and debris. Only biocidal agents registered by the U.S. Environmental Protection Agency (EPA) specifically for use within HVAC system shall be used. Biocidal agents shall be applied in strict accordance with manu facturers instructions. Biocidal coating products for both porous and non-porous surfaces shall be EPA registered, water soluble solutions with supporting efficacy data and MSDS records. Biocidal coatings shall be applied according to manufacturers instr uctions. Coatings shall be sprayed directly onto interior ductwork surfaces, rather than fogged downstream onto surfaces. A continuous film must be achieved on the surface to be treated by the coating application. Application of any biocidal coatings sh all be in strict accordance with manufacturers minimum millage surface application rate standards for effectiveness. Cleanliness Verification General: Verification of HVAC System cleanliness will be determined after mechanical cleaning and before the application of any treatment or introduction of any treatment-related substance to the HVAC system, including biocidal ag ents and coatings. Visual Inspection: the HVAC system shall be inspected visually to ensure that no visible contaminants are present. If no contaminants are evident through visual inspection, the HVAC system shall be considered clean; however, the Governm ent reserves the right to further verify system cleanliness through gravimetric or wipe testing analysis testing as specified herein. If visible contaminants are evident through visual inspection, those portions of the system where contaminants are visible shall be re-cleaned and subjected to re-inspection for cleanliness. Gravimetric Analysis: At the discretion and expense of the Government, sections of the HVAC system may be tested for cleanliness using the NADCA Vacuum Test (gravimetric analysis) as spe cified in applicable NADCA Standards. Levels of debris collected shall be equal to or less than acceptable levels defined in applicable NADCA Standards. If gravimetric analysis determines that levels of debris are equal to or lower than those levels specified in applicable NADCA standards, the system shall be considered clean and shall have passed cleanliness verification. If gravimetric analysis determines that levels of debris exceed those specified in applicable NADCA standards, the system shall not be considered clean and those sections of the system which failed cleanliness verification shall be re-cleaned at the expens e of the HVAC system cleaning contractor. Gravimetric analysis shall be performed by a qualified third party experienced in testing of this nature. Cleanliness verification shall be performed immediately after mechanical cleaning and before the HVAC system is restored to normal operation. Verification of Coil Cleaning: Cleaning must restore the coil pressure drop to within 10 percent of the pressure drop measured when the coil was first installed. If the original pressure drop is not known, the coil will be considered clean only if the coi l is free of foreign matter and chemical residue, based on a thorough visual inspection (see NADCA Standards). Post-Project Report: At the conclusion of the project, the Contractor shall provide a report to the C.O.R. indicating the following: Success of the cleaning project, as verified through visual inspection and/or gravimetric analysis. Areas of the system fou nd to be damaged and/or in need of repair. Applicable Standards and Publications -- The following current standards and publications of the issues currently in effect form a part of this specification to the extent indicated by any reference thereto: National Air Duct Cleaners Association (NADCA) : NADCA 1992-01, Mechanical Cleaning of Non-Porous Air Conveyance System Components 1992 National Air Duct Cleaners Association (NADCA): Understanding Microbial Contamination in HVAC Systems, 1996.
