FUMEFUME CUPBOARDSCUPBOARDS

ASHRAE 110-95 CERTIFIED

TOTAL LABORATORY SOLUTIONS

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 GENERAL OVERVIEW

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. Front End Fixture Panel Quickly and easily removed to provide convenient

to service fixture from the front of the hood. Side panel Convenient access to sash weight, service fixture

and plumbing lines. Inner Liner Fiberglass/stainless steel Sash 6mm double layered glass with safety lamination Exhaust Point 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.

Vapor Proof Light Casing Shielded with glass plate properly sealed. Lights Uses energy saving fluorescent light. Switches Two rocker switches located with easy reach of

the operator control both the internal lights and blower.

Service Fixtures Remote valve with side outlet Fixture Lines Water fixtures are plumbed with copper tubing

while gas is plumbed with tin-lined tubing Electrical Outlets 220V, 13Amp single-phase electrical outlets are

mounted on the front-end panel Table Top Epoxy table top specially designed to provide

chemical resistant inside the fume hood Table Top Material & Construction One-piece corrosion resistant from a special

formulated of epoxy resins to withstand chemicals. Dished and contoured

CERTIFICATION In providing a fume hood that serve the purpose as a protection shield to laboratory personnel from a hazardous chemicals and agents in laboratory, ASL fume hoods have been tested by independent laboratory and certified conformed to the international standards of ASHRAE 110-95 PROTOCOL.

Perchloric Acid Fume Hood is used when work with perchloric acid. 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.

Radioisotope fume hood should be designed too efficiently ventilate procedures using radio-chemicals. The fume hood must be able to provide a flow of air sufficient to extract the fumes from within the work area and keep away from the operator to avoid ingestion, inhalation or skin contact. Hood interior is constructed of seamless, ground and polished 304 or 316L stainless steel with covered interior corner. Free of joints, cracks or gaskets to protect against spills and radioactive build-up. The hood comes with integral cup-sink which can be used to dispose of liquids safely and may act as a drain during cleaning procedure.

FUME CUPBOARD – Radio Isotope Hood

All electrical component, semi-conductor or component that can produce spark should be isolated or at the external of the fume hood. Lights should be housed in an explosion proof casing. Sash material should be an explosion proof material.
