Ventilation planning in the laboratory must meet various requirements. Below, you will find the most important standards and guidelines that ensure the safety of laboratory personnel at all times and prevent potential health hazards.

VENTILATION SYSTEMS IN LABORATORIES: TS 17441
TS 17441 provides an overview of the most important exhaust air equipment in the laboratory and lists all types of air that must be taken into account during planning (fresh, supply, extract, recirculation, exhaust and, if necessary, secondary air). Rooms that are related to or connected to the laboratory (e.g., pressurised gas cylinder rooms) must also be included in the overall organisation of the ventilation system. Furthermore, the risk assessment may result in further safety-related requirements for the supply and extract air.
The EN 14175 standard regulates constructional aspects of fume cupboards and specifies protection goals and safety requirements. In addition, reference is made to the consideration of disturbing influences, such as draughts in the room or passenger traffic. Among other things, the following shall be guaranteed:
This standard specifies the safety requirements for laboratory cabinets. This includes safety cabinets for flammable liquids and cabinets for pressurised gas cylinders.
DIN 12925 also covers the testing and operation of these laboratory facilities.
EN 1822 regulates the classifications of industrial air filters. A distinction is made between three groups of filters:
Our TROX systems have fire dampers, volume flow controllers and special fans for potentially explosive atmospheres, the safety of which has been confirmed by ATEX certificates. Even before a potentially dangerous gas concentration arises, the laboratory air is cleaned and removed by automatic controls.
ATEX defines essential health and safety requirements and conformity assessment procedures to be applied before products are placed on the EU market.
The GMP rules are laid down in national and international regulations. The core points of GMP include the requirements for hygiene, premises, equipment, documentation and controls.
Laboratories work with a wide variety of substances, organisms and toxins. When handling such demanding materials, safety and compliance with applicable (hygiene) rules are paramount in order to avoid health hazards. The protection of people is the focus at all times. Depending on the security level of the laboratory, the type and scope of the applicable regulations vary. The respective premises are classified into so-called Biosafety Levels (BSL), which build on each other: BSL 1 is the lowest and BSL 4 the highest safety level.
The different requirements of different laboratory types and safety levels must also be taken into account when planning air management. We are happy to be your reliable partner when it comes to equipping your premises with fully comprehensive and individual corresponding systems. Benefit from the many years of experience of our TROX experts and receive the best support from laboratory planning to maintenance, even for demanding hygiene and safety requirements.
Biosafety Level 1 laboratories deal with known substances and work equipment that pose a minimum risk potential to laboratory personnel and the environment.
Most laboratories in Germany belong to the Bio-Safety Level 2 category. Infectious substances or toxins with a medium risk for employees and the environment are worked with in corresponding premises. The corresponding substances become dangerous if they are accidentally inhaled, swallowed or brought onto the skin.
In addition to the regulations for BSL 1, the following further safety standards are observed in BSL 2:
Biosafety level 3 is used for laboratories that work with hazardous substances. The substances can cause severe and potentially fatal diseases via the respiratory tract.
Therefore, in addition to the safety measures of BSL 1 and 2, the following points are added:
Laboratories with Biosafety Level 4 are high-security laboratories. Here, micro-organisms are studied that are transmitted by aerosols and can cause severe to fatal diseases in humans for which there are no vaccines or treatments yet.
In addition to the measures in BSL 1-3, the following factors must be observed:
