The forced ventilation can be carried out by one of our standard extraction fans or by a suitable in-house air extraction system. The exhaust air is to be discharged from the building into a hazard-free zone. The operation of safety cabinets for the storage of flammable liquids as per DIN EN 14470-1 is governed by TRGS 510. When operating the cabinets without technical forced ventilation, additional replacement measures have to be taken to ensure comparable explosion protection. The herfore required risk assessment we suggest to undertake as per BGR 104 (EX-RL) example collection 2.2.8. For this reason, and also to avoid the presence of hazardous vapors in the atmosphere near the cabinet, we always recommend that safety cabinets are operated with an extraction fan (min. air exchange rate 10 times per hour) for proper operation in accordance with TRGS 510, annex 1! If an extraction fan is to be used in an EX-endangered zone then it is essential that an EX-proof version is used! If the safety cabinet is used together with an extraction fan then it is no longer necessary to set up and maintain an EX-zone around the safety cabinet!
