1. INTRODUCTION

This Specification defines the requirements for the design, procurement, materials, fabrication, assembly, testing, and shipment of a Ventilated Modular Wet Cleaning Bench (also referred to as the

Bench) that will provide the capability to perform cleaning of equipment using chemicals and mechanical processes while protecting the worker from chemical fumes which will be exhausted via the facility exhaust system. The ORNL facility exhaust system is a VAV (Variable Air Volume) system. The Bench will utilize moveable sashes to limit chemical fumes escaping into the surrounding room while providing access for workers to clean parts and equipment and provides flow alarm(s) if exhaust ventilation is not adequate. The Bench also provides for the collection of any rinse water in suitable containers, provision for future fire sprinkler installation, lighting for the interior work area, 120V 60Hz convenience outlets, compressed air connections, process water connections and overhead exhaust connections. The Bench has been conceptually designed to fit in a designated space and footprint in a facility at the Oak Ridge National Laboratory (ORNL), hereafter referred to as the Company. Chemicals anticipated to be used in the Bench include typical laboratory chemicals such as detergents, acetone, alcohol, nitric acid, etc.

2. REFERENCE DOCUMENTS

The Ventilated modular Wet Cleaning Bench shall conform to the requirements in the following document list. Additional requirements are found in the General Project Specification, EX-00-

5. DESCRIPTION

The Ventilated Modular Wet Cleaning Bench is conceptualized as a four-side access rectangular shaped bench-type fume hood with combination sashes and additional features to facilitate chemical and mechanical cleaning of equipment as well as collection and storage of chemical rinse fluids for disposal. The external dimensions of the entire assembly shall be approximately 120 inches wide x

60 inches deep x 96 inches high. Chemicals anticipated to be used in the Bench include typical laboratory chemicals such as detergents, acetone, alcohol, as well as <3-4 molar nitric acid, etc. The

Bench shall provide the user ready access to facility supplied fluids including water for cleaning and rinsing, compressed nitrogen for part blow-off, and compressed air for pneumatically powered rotary tools. Self-contained work surface and storage cabinet lighting is required, as well as electrical convenience outlets. The ORNL Facility exhaust system is a VAV based system which provides two drops in close proximity to the Ventilated Modular Wet Cleaning Bench. The two drops are a 14-inch diameter with design capacity of 1650 cfm and a 12-inch diameter with design capacity of 1250 cfm. The exterior of the Ventilated Modular Wet Cleaning Bench shall be chemically resistant finish which meets tests and requirements of SAE AMS-STD-595 with color #27769, or Company approved equal.

The Ventilated Modular Wet Cleaning Bench will be fabricated at the Seller’s facility and shipped in three or more primary sub-assemblies to the Company’s facility for installation by the Company or a designated sub-contractor. The three sub-assemblies are the Ventilated Enclosure, the Work Top and the Base Cabinets.

Protection for Laboratories Using Chemicals. Additionally, all materials interior to the enclosure shall have a flame spread rating of 25 or less when tested in accordance with ASTM

E84, Standard Test Method for Surface Burning Characteristics of Building Materials or UL

723, Test for Surface Burning Characteristics of Building Materials.

5.1.2 The exterior shall be finished to match the base cabinets. The jambs shall be designed to reduce the turbulence as the air enters the unit in order to eliminate backdraft out of the enclosure. The area between the double walls shall be used to house utility services, sash counterbalances, etc.

Ventilated Modular Wet Cleaning Bench Page 9 of 17

5.1.3 The Ventilated Enclosure shall be equipped with baffles as required and shall be made of material suitable for chemical resistance. Baffles may initially be fixed or adjustable as deemed necessary by the Seller to ensure proper performance of the Enclosure but shall be fixed after successful testing and balancing prior to shipment to the Company. Baffles shall be designed and positioned to provide an average air velocity of 100 feet per minute at any point on the face opening with any two vertical sashes positioned open and the horizontal sliding sashes closed, or with all vertical sashes closed and any two horizontal sliding sashes set fully open. For this purpose and measurement, the vertical sash open position is set at 18 inches.

5.1.4 The Ventilated Enclosure shall provide a clear interior work volume of 108 inches wide (front access) x 42 inches deep x 30 inches high. Rear access opening may be reduced to 108 inches wide to provide space for utility chases and counterweights (see Dwg SE-02-00310). The overall exterior size of the Ventilated Enclosure should not exceed 120 inches wide x 60 inches deep x 60 inches high including the duct connection and upper shroud but excluding the Base
