Fume cupboards with ejector technology or sash? The technology comparison.
In many laboratories, classic fume cupboards with front sash are used. In practice, however, working behind the pane often means considerable compromises. The alternative is called ejector technology: we have compared both systems and show you which one is ahead.
Anyone who handles, uses or "only" stores hazardous substances cannot avoid it: the risk assessment. For 25 years it has been the central element in occupational health and safety. In our FAQs we have put together the answers to the most frequently asked questions on the subject of "Risk assessment for hazardous substances".
The classification of Ex zones depends on the atmosphere of the respective zone. A distinction is made between gas and dust explosion hazard zones and these are divided into three zones each.
Zone zero to two concern gases, mists or vapors. In zone 0, there is a permanent explosion hazard. Zone 1 designates areas in which an explosive atmosphere may occasionally form during normal operation. In Zone 2, it can be assumed that no explosive atmosphere is present or occurs only briefly during normal operation.
The zone classification for dust explosions corresponds to that for gases. In zone 20, a permanently explosive atmosphere is present due to flammable substances in the air. In zone 21, explosive atmospheres are expected to occur only occasionally during normal operation, and in zone 22, explosive atmospheres are not present or are present only for a short time. Terms such as "normal operation" or "short-term" are not clearly defined by the European Union. These are defined in national regulations, which may result in differences in categorization in different countries.
