2.3 Proper use
2.3.1 General rules for all laboratory fume cupboards
The fume cupboards may be used only for the following purposes/applications:
• use in buildings.
• for the extraction and discharge of harmful gases produced in a conventional laboratory during chemical
processes. Each laboratory fume cupboard may only be subjected to chemical, thermal and mechanical
stress according to its prescribed purpose (authorization) and material selection.
• under normal laboratory conditions. The additional information regarding the T032 laboratory fume
cupboards: construction types and safe operation of the BG RCI - Professional Association of the Raw
Materials and Chemical Industry - must be strictly observed.
• The sash must be kept closed at all times. Exceptions to this are inspections and short-term
interventions, assembly, dismantling and loading, as well as loading/feeding of an apparatus, whereby
the opening of the sash must be limited to the extent necessary for the activity. In this case the work
should preferably be carried out through the laterally movable parts of the sash.
• No subsequent changes or modifications may be made to the construction of the fume cupboard
(e.g. modification of the rear panel, additional openings in the side panels for pipelines, gas hoses, etc.).
Warning of toxic substances
Warning of electrical voltage

14 User Manual | Laboratory Fume Cupboard | Safety
Such changes may impair the flow behaviour and thus the protective effect of the laboratory fume
cupboard.
• Underneath larger structures by which, due to their surfaces, a kind of “slipstream” is created on the
worktop, sufficient clearance (at least 5 cm) (floor clearance) to the worktop, as well as a sufficiently
large clearance to the sash (at least 10 cm) must be observed.
The fume cupboard may not be used in a potentially explosive atmosphere. Wesemann GmbH offers EX fume
cupboards for such areas.
2.3.2 All-purpose fume cupboards
All-purpose fume cupboards are table fume cupboards, fume cupboards for low ceilings/spaces, low work-
level cupboards and walk-in fume cupboards. The all-purpose fume cupboards are not special fume cupboards
according to DIN EN14175-7:2012. They are therefore:
• not fume cupboard for high thermal loads
• not fume cupboards for high thermal loads in conjunction with acid digestions
• not perchloric acid fume cupboards
• not hydrofluoric acid fume cupboards
• not micro-biological safety work benches
• not suction boxes with air recirculation
• not radionuclide fume cupboards
They may not, therefore, be used as the said special fume cupboards and their applications.
2.4 Improper use
Any use which is not mentioned in the section 2.3 Proper use is considered to be improper use.
2.5 Obligation of the operating company
The operating company undertakes only to allow persons to work on fume cupboards:

15

the respective field, as well as the experience in the activities to be carried out.
• who have been trained.
• who have read this user manual carefully.
2.6 Obligation of the personnel
All persons working on the fume extractors or their components undertake:
• to observe the basic regulations regarding occupational safety and accident prevention.
• to have read this user manual carefully.
Furthermore, appropriate protective clothing is to be worn when working on the fume cupboard.

of the following causes:
• Improper use of the laboratory fume cupboard.
