Room Ventilation
The room ventilation should preferably be a ventilation system that complies with the
national requirements for the application.

The inlet air and exhaust air openings of the room ventilation must be located so that
drafts are prevented from impairing the function of the safety cabinet air system.
Correct Location
Choose a draft-free location where the safety cabinet does not interfere with the plant traffic.
Figure 1 Correct Location
This figure shows preferred locations for safety cabinets and unsuitable locations, not in
accordance with the safety requirements.
Unsuitable locations: The locations [1], [2] and [3] are not suitable because they are
exposed to drafts from windows and doors.
Location [5] is undesirable because it is in range of plant traffic and within the exhaust air
range of a ventilation system [4].
Preferred locations: Preferred locations [6], [7], and [8] are correct because they are in
a draft-free section of the room and not exposed to plant traffic.
