FUME CUPBOARDS ASHRAE 110-95 CERTIFIED TOTAL LABORATORY SOLUTIONS FUME CUPBOARD GENERAL OVERVIEW GENERAL OVERVIEW Fume hoods are one of the most important components used to protect laboratory personnel from exposure to hazardous chemicals and agents used in the laboratory. When used properly, they can provide an effective backup safety device for the containment and exhaust of toxic, offensive or flammable materials when the containment of an experiment or procedure fails and vapors or dusts escape from the apparatus used. Average face velocity is the main criterion that is used to determine if a hood is functioning satisfactorily as a safety device for the containment and elimination of airborne contaminants. Factors that can affect face velocity and thus hood performance include baffle position, cross drafts, air volume, hood features, hood location, foot traffic and user work practices. STANDARD CONFORMANCE AND COMPLIANCE The design and performance of fume hoods are generally conform to the following international standards: SEFA 1-2002 ASHRAE 110-95 AS2243-8 EN 14175 BS 7258 FUME HOOD CONSTRUCTION Fume Hood Superstructure In general, the fume hood shall come with worktop, sash, base storage cabinet, control and display panel, electrical distribution board, lighting encased with a vapor proof casing and utility facilities. Where the construction material used is concern, it must be selected with a predominant view to safety in a hazardous environment. The fume hood shall have dual wall construction with an air gap within for safety. Materials used must be resistant to chemicals, heat abrasion, impact vandalism and fungi. The fume hood design needs to have access for easy decontamination, cleaning and maintenance. All electrical fittings shall be properly insulated and exposed surface shall be electrically earthed to the earth terminal of the isolator. Typically construction acceptable for fume hood shall have an external wall of powder coated epoxy steel material or fire resistant glass-fiber reinforce plastic and an internal chamber molded, one piece, fire resistant fiberglass material. It shall be furnished with clear lamination, safety glass of 6mm thickness, tampered proof sash assembly with counter balanced weight. The fume hood shall be constructed with a well designed baffle and internal lining with coved corners. Materials used in the construction of the fume cupboard working space shall be able to minimize resistant to air flow and to avoid turbulence, backflow and air eddied. Fluctuation in the sash velocity as the sash is raised or lowered should be minimal. FUME CUPBOARD GENERAL OVERVIEW Work Top The epoxy table top shall be dished at certain angle to prevent spill over. The worktop shall be 900mm form final floor level and have resistant to solvents, acids, heat and impact. A suitable sink shall be recessed in the left corner beneath the gooseneck faucets. General Purpose Base Cabinet The storage cabinet shall be of metallic type and come with removable shelf and rear panels to provide access to service plumbing. The shelf and bottom shall be lined ribbed rubber matting. The toe space shall be protected by coved rubber molding. Doors shall be close fitting type and no parts of the cabinet shall support combustion. Air vent piping shall be provided to extract any escaped fume from within the base cabinet storage area. Air vent pipe shall be permanently connected to the main exhaust PVC pipe from the fume hood. Polypropylene material sheet or drip tray shall be provided in base cabinet shelf to protect shelving from coming into contact with any split chemical solution. Fume Hood Utility All service valves or devices shall be fitted to the sides of the fume hood fascia. All handles shall be fitted with international coding system. FUME CUPBOARD Performance/ Specification/ Certification FUME HOOD PERFORMANCE The fume hood shall be of a demonstrable aerodynamic design capable of containing effluent generated within the hood at a face velocity of at least0.5 m/sec. The interior lighting shall have a minimum of 700 lux at worktop level. GENERAL SPECIFICATION Material Hood Exterior is epoxy coated steel Front Panel Easily removed without tools for easy accessibility to electrical wiring facilities. Quickly and easily removed to provide convenient to service fixture from the front of the hood. Convenient access to sash weight, service fixture and plumbing lines. Fiberglass/stainless steel 6mm double layered glass with safety lamination The exhaust outlet reduces static pressure loss to ensure smooth, efficient airflow. The integral condensation collection rings prevents condensed vapors in the ductwork from entering the work area and channels them to drain or collection container via the rubber tubing supplied. Shielded with glass plate properly sealed. Uses energy saving fluorescent light. Two rocker switches located with easy reach of the operator control both the internal lights and blower. Remote valve with side outlet Water fixtures are plumbed with copper tubing while gas is plumbed with tin-lined tubing 220V, 13Amp single-phase electrical outlets are mounted on the front-end panel Epoxy table top specially designed to provide chemical resistant inside the fume hood One-piece corrosion resistant from a special formulated of epoxy resins to withstand chemicals.

The inner line should be seamless to prevent potential trap of the fume / particles that will crystallized. Fume from the hood will go through a scrubber unit that will wash down the fume before it goes to the ducting system. These type of fume hood need dedicated ducting and exhaust system. VSD or VAV system can be used together with the fume hood to increase protection of the operator.
