Belgian workplace regulations (the Code on well-being at work) require every storage area for hazardous substances to be adequately ventilated. Our safety cabinets have air ducts ready for connection to mechanical extraction to the outside.
Where an exhaust duct is not possible, a recirculating filter such as the Asecos UFA.025.030 filters the vapours with activated carbon and returns the cleaned air to the room. Your risk assessment determines whether recirculation is sufficient.
When extraction is needed and what Brussels Environment requires is explained in our guide under extraction and ventilation.
