Safety cabinets according to DIN EN 14470 must be provided with supply and exhaust air connections in order to prevent dangerous vapors from escaping into the work area with the help of a technical exhaust air system. The ventilation must be routed to the outside at a safe point. Alternatively, ATEX-compliant (2014/34/EU) circulating air filter systems have proven themselves in practice for safety cabinets for solvents. Safety cabinets without technical ventilation must be grounded according to TRGS 510 due to the increased risk potential.
YOUR BENEFIT FROM TECHNICAL VENTILATION!
In order to ensure maximum safety for your employees, connection to the technical exhaust air is strongly recommended for many chemicals. DÜPERTHAL offers various solutions to prevent hazardous vapors escaping into the work area. All fans and device parts comply with the 2014/34/EU (ATEX) directive and thus meet the highest safety standards.
Air conditioning systems according to DIN 1946-7
Safety cabinets are exhaust air systems as soon as they are operated with exhaust air or circulating air. Exhaust air systems are to be planned, set up and operated in such a way that there is no risk of a hazardous, potentially explosive atmosphere. Released gases, vapours, aerosols must be discharged and diluted to such an extent that health hazards via the breathing air are avoided. Only continuous monitoring of the ventilation enables the operator to take suitable technical or organizational measures to avoid the hazards that may arise in the event of a ventilation failure. When designing the systems, it must be taken into account that the sound pressure level of 52 dB(A) in the room is not exceeded.
