Local Exhaust Ventilation (LEV) Systems
LEV systems (Local Exhaust Ventilation systems), also known as extraction or fume control, can be very effective in controlling airborne contaminants. The following article discusses Point Extraction Ducts, LEV Enclosures and the design features and performance criteria for both of them. Point Extraction Ducts LEV Point extraction systems can...
Biological Safety Cabinets
Biological safety cabinets (BSC) will provide both product and operator protection, this is achieved by recirculating HEPA-filtered air within the cabinet as well as providing an inflow at the face opening. Biological safety cabinets are specifically designed for the handling of samples that present a biological hazard. Design...

Mobile Fume Hoods: Design, Performance & Positioning
Mobile fume hoods are generally designed as a recirculatory system providing exposure protection from Volatile Organic Substances (VOC’s). Typical applications that a mobile system will be suitable for are: Titration, Karl Fischer analysis, General Solvent Handling, Solvent Disposal etc. Design Features & Performance Criteria Mobile Fume Hoods should perform to...
Ducted Fume Hoods: Design, Performance & Positioning
Ducted Fume Hoods, or built-in fume hoods, are the most commonly used containment devices within a laboratory, and for this reason often considered as the first option when containing any lab scale operation. Design Features & Performance Criteria for Ducted Fume Hoods The Fume Hood should perform to a...
Specific Engineering Controls for Potent Compound Handling
Strategically designed engineering controls should be selected and employed, as appropriate, as the primary means of reducing occupational health risks. Specific engineering controls for potent compound handling include Isolator/Glovebox technology, wherein work processes are physically contained within an isolation chamber that an operator may access via glove ports. Ventilated Balance...
Local Exhaust Ventilation Controls for Pharmaceutical Laboratories
General Guidance for Local Exhaust Ventilation Controls: Providing effective extraction and filtration for localized containment systems. Each laboratory should be equipped with enough fume cupboards and ventilated enclosures for the work anticipated. Fume cupboards should be connected to a high volume, low static, mechanical exhaust system. Emission control or stack...
Air Handling Recommendations for Pharmaceutical Laboratories
Air Handling Recommendations for Pharmaceutical Laboratories handling drugs category 3 & 4. HEPA filtration of exhaust air is recommended for areas handling Category 3 substances and required for areas handling Category 4 substances. The air leaving these areas must be clean and contamination-free. A minimum of 15 air changes per...
Building Design Criteria for Pharmaceutical Laboratories
Design criteria for laboratories - General Laboratory Design: Providing a basic level of safety design for the handling of Low-Intermediate toxicity compounds.In order to ensure that a potentially hazardous environment within the Laboratory does not affect areas outside the designated laboratory, a negative differential air pressure relative to the surrounding...
