Understanding how lithium energy storage devices work is very important to be able to assess their hazard potential. There are many different energy stor- age systems where lithium is used in a pure or bonded form. Lithium cells are basically divided into primary (non rechargeable) and secondary (rechargeable) cells. A battery pack is made up of several cells depending on capacity. Each lithium cell has a positive and a negative electrode, the anode and the cathode. Between them, there is an ion-conducting electrolyte. This ensures the transport of the lithium ions between the electrodes during the charging and discharg- ing processes. The best known form of lithium energy storage device is the lithium-ion battery, in which a liquid electrolyte is used. The separator is also an important part of the device. It prevents direct contact between the anode and cathode and therefore prevents a short-circuit. During the discharging process lithium ions and electrons are released on the anode side. The electrons flow through the external circuit and perform the electrical work. At the same time, the lithium ions cross through the electrolyte fluid and the separator over to the cathode. When charging, the process is reversed. Depending on the system, the design of a lithium energy storage device and the materials used may vary. In a lithium polymer battery the electrolyte is bound in the molecular structure of a polymer foil. There is therefore no need for the special separator. Lithium polymer energy storage devices are only able to generate low discharge currents. The polymer foil however allows for a flat design, which is useful in mobile telephones and laptops for example. The thin film lithium cell is an energy storage device where the electrolyte is replaced by an ion-conductive glass. This allows lithium metal to be used and therefore provides an extremely high energy density. This technology is currently an important part of research into lithium energy storage devices.

While the German Federal Institute for Occupational Safety and Health (BAuA) regards lithium-ion batteries as products under the REACH regulation, the American Occupational Safety and Health Administration (OSHA) classifies batteries as mixtures. In practice, many companies prepare and make available safety data sheets for lithium batteries even without a legal obligation to do so. These usually provide valuable information on battery storage and handling. However, details of chemical composition can often also be found, which provide information on the hazard. Basically a lithium battery can be divided into the anode, electrolyte fluid and cathode. The conducting salt contains, among other things, fluorine (F). If hydrofluoric acid (HF) escapes in an unconcentrated form from a damaged lithium battery, various hazardous situations can arise. Various materials are used in the cathode, often including iron, manganese, cobalt or nickel. The exact composition of the cathode material significantly determines properties such as lifetime, charging times and performance. As a rule, graphite (C) is used as the anode material, which does not have to be labelled according to the CLP regulation. The electrolyte fluid consists of an organic solvent and a conducting salt. While there is a wide variety of possible solvents, lithium hexafluorophos- phate LiPF6 is almost exclusively used as the conducting salt. Electrolyte fluid = organic solvent + conducting salt LiPF6. The exact chemical composition of the respective solvent mixture is usually a manufacturer's secret. However, by looking through various data sheets, an overview of the components used can be obtained. The flashpoints of the solvent components range from +160 °C to partly below 0 °C. This explains the thermal instability of a lithium battery. More information can be found F R O M P. 1 0 . Chemical elements in lithium batteries and their hazard potential.

But according to VDE, this only applies as long as everyone handles them properly. As soon as there is a technical fault or a battery is damaged, the situation can quickly become critical. As a result, the German Insurance Association (GDV) calls for lithium batteries to be "treated as a hazardous substance in principle". The situation becomes especially dangerous when a lithium battery releases its stored energy in an uncontrolled manner. As soon as the heat created exceeds the melting point of the separator, an uncontrollable chain reaction is started, the dreaded "thermal runaway". This results in an explosive burning of the battery. These lithium-ion battery fires are difficult to control, spread quickly. Often, all the fire brigade do in such situations is protect the neighbouring areas.

Large batteries, for example from burning electric cars, regularly present fire brigades with enormous challenges. T H E S E F I R E S A R E H A R D T O C O N T R O L . W H Y I S T H A T ? This question can be answered by looking at the construction of a trac- tion battery. A large traction battery consists of many smaller cells that are connected together. If a single cell heats up, in the worst case in the middle of the module, the neighbouring cells will also inevitably heat up. This results in a chain reaction that leads to a considerably higher release of energy. If the chain reaction was triggered at the centre of the battery, it is almost impossible to reach it with an extinguishing agent, e.g. water, and thus stop or contain the reaction. If you now try to cool the module, the water only reaches the outer layers or the battery housing. The situation is different for smaller modules where fewer cells are used. Here, external cooling usually has a direct effect on the reacting cells. In the summer of 2019, the VdS published leaflet 3856 "Sprinkler protection of lithium batteries". For the first time a differentiation was made by energy content per storage unit and the risk was classified according to the follow- ing table: The recommendation is to store a maximum of 50 kWh per storage unit (e.g. one Euro pallet). This is equivalent to Hazard Level II. The sprinkler system H A Z A R D L E V E L ( H L ) I II III R I S K Low Medium High E N E R G Y C O N T E N T I N K W H / S T O R A G E U N I T < 1 1.0–50 > 50 must be designed in accordance with VdS CEA 4001. Tests by the Ameri- can property insurer FM-Global and the German Insurance Association (GDV) have shown that the spread of lithium battery fires in high racks can be pre- vented by a targeted sprinkler system. However, the findings from the tests are only valid for small lithium batteries packed in cardboard boxes. The sprinkling of large battery units is nevertheless advisable, as although the fire is not usually extinguished at the individual battery, the spread to neigh- bouring batteries can be slowed, if not prevented. Powder extinguishing agents such as aerosols suppress the fire at the bat- teries. Especially with smaller storage volumes, such as safety cabinets or emergency containers, valuable time can be saved. A cooling effect does not take place here, however. Extinguishing granules, which are often used in transport boxes for faulty lith- ium batteries, thermally insulate the battery. The extinguishing or insulation effect is immediately active and functions completely autonomously. A pre- requisite, however, is that the batteries are surrounded by a sufficient quan- tity of granules, which greatly restricts handling.

Country-specific, bureaucratic hurdles in the approval procedure are a thing of the past with the new European approval (ETA). DENIOS fire-rated stores are the first and so far only construction products of this kind with official ETA approval / CE marking in accordance with European Regulation (EU) No. 305/2011. In addition, they have been successfully tested and classified as a complete system in a fire test by the French testing institute Efectis, a body designated by the EU. E X C E L L E N C E I N F I R E P R O T E C T I O N . How can the safety of hazardous materials stores with fire protection be clearly demonstrated? By not only developing them on the basis of theoreti- cal information from suppliers, but by subjecting them to real fire tests. Our experience has shown that real fire tests always lead to product improve- ments. To ensure that the fire resistance required in the event of a fire is also maintained in the event of damage, our products go through a real baptism of fire at an independent testing institute. Step by step, our engineers follow each measurement from the sensors installed on the test object and draw decisive conclusions: do the matched components work or do they still need to be optimised? For some companies, it is sufficient if the test is completed after the 90 min- utes required in Germany. As an international supplier, however, DENIOS goes a step further and tests all products for 120-minute fire resistance in order to be able to guarantee the highest level of protection throughout Europe. Of course, the corresponding evidence for each product is provided in the documentation. DENIOS also pools knowledge group-wide in order to channel it into the development of innovative products and equipment, and to continuously improve the advice and services we offer. F I R E P R O T E C T I O N A S A S Y S T E M . The fire protection of a building product is not achieved by individual EI-120 components. Reliable fire protection results from the interaction of all the components in the system as a whole. At DENIOS, you'll receive a certificate with every hazardous materials store demonstrating that the entire system has been successfully tested. In addition, you'll benefit from our holistic approach: starting with advice, through development and production, to service, we'll find solutions together for your individual application. In this way, fire protection is ensured by a self-contained and coordinated system. F I R E P R O T E C T I O N A N Y W H E R E . Risks resulting from the storage of flammable media are the same all over the world. A fire does not care whether it breaks out in a hazardous materials store in Berlin or Beijing. That is why it is so important to have an interna- tional perspective on the issue. Local legislation decides how the risks are to be assessed and prescribes appropriate protective measures. As DENIOS is represented in over 20 coun- tries in Europe, Asia and North America, we are familiar with the local legis- lation. Our experts on site will design the optimal hazardous materials store for your application. F I R E P R O T E C T I O N I N N E W D I M E N S I O N S . The challenges you face as a customer drive our innovation. It's our mis- sion to make hazardous materials storage as safe, convenient and efficient as possible. Initially, DENIOS fire-rated stores were only equipped with wing doors, as sliding doors were not available as an alternative on the market. However, DENIOS recognised the advantages of the sliding door design for everyday work: larger room volume, protection against wind loads and electrical oper- ation from a forklift. Without further ado, an in-house development was started which, in contrast to the attempts of other manufacturers, success- fully passed the fire test and was classified as EI₁ 60/EI₂ 120.

S A F E T Y R U L E S F O R C H A R G I N G L I T H I U M B AT T E R I E S . When charging lithium batteries, the potential risk is significantly increased compared to storage. This is especially true if the batteries are damaged. The greatest danger is if a short circuit occurs in the battery when fully charged. This is when the stored energy is at its greatest and therefore the effects of thermal runaway S E E P. 8 . The self-reinforcing reaction of the lithium battery can lead to bursting. If safety rules are observed and the storage and are also at their highest charging conditions are optimally matched to the stored goods, this risk can be minimised. T H E C A R D I N A L R U L E : D O N O T C H A R G E A D A M A G E D B A T T E R Y ! A V O I D D E E P D I S C H A R G E ! VdS recommends that damaged or defective batteries be immediately removed from storage and production areas. However, it should be borne in mind that a defect is often not externally visible and it is therefore not easy to assess the condition of a battery. To be on the safe side, you should always store batteries whose condition is unknown in a separate quarantine store. This store must be taken into account in the operational fire protection design. The compact RFP 115 Li-Ion fire-rated store, for example, can be used as a quarantine store F R O M P. 2 6 . The charging of lithium-ion batteries is also critical if they have not been used for a long time or have been fully discharged. They can be permanently dam- aged by deep discharges, causing a chemical reaction during charging. This is why, for example, garden tools with rechargeable batteries have a trickle charge, which corresponds to a charge level of approx. 30 %. This reduces aging effects and prevents deep discharge. O N L Y C H A R G E L I T H I U M B A T T E R I E S I N A M O N I T O R E D E N V I R O N M E N T . Cold or high temperatures and high humidity can also cause damage to the cells. Therefore, only charge lithium batteries under supervision, at room temperature and in a fire-rated location.

S A F E S T O R A G E A N D C H A R G I N G C O N D I T I O N S . In most commercially available rechargeable batteries, the battery manage- ment system (BMS) integrated in the manufacturer's charger prevents over- charging and deep discharge. It is a safety feature that protects the performance of the battery and pre- vents defects. The BMS can also be part of the battery itself. The fire-rated store WFP Li-Ion already offers safety in case of fire thanks to its certified fire protection. By equipping the unit with air-conditioning tech- F R O M P. 7 8 and monitoring electronics nology for outdoor installation F R O M P. 7 6 , additional precautions for preventive fire protection can be taken.

Batteries weighing up to 700 kg and measuring 2,200 x 1,800 x 800 mm (W x D x H) are set via a double-wing door on the room system storage grid. An automatic door closing and hold-open system keeps the door open during loading and unloading. To close the doors, the retaining magnets are dis- connected from the power supply by means of a manual release button. In the event of a fire the fire detection system in the room automatically closes the door. The second, walk-in section of the room is equipped with a 1-wing door and storage shelves to store individual battery modules and cells. Removable grids suitable for pallet trucks form the base. An LED interior lighting system ensures good visibility in both sections of the room. Further useful features include a 230 V socket and an Ethernet connection. F U R T H E R C A S E S T U D I E S . The climate in the room is adjusted to the legal requirements for air quality and temperatures of 22 °C +/-2 K all year round. Excellent energy efficiency is ensured by the high insulation thickness of the fire protection panels of 100 mm and an interplay of air conditioning, heating and technical venti- lation, all optimally coordinated by control technology. The air condition- ing system is a heat exchanger with CFC-free refrigerant. An electric finned tube heater serves as a supporting heater for the air conditioning system. A circulating air fan distributes the temperature-controlled air evenly through- out the room system. The system is designed for 0.4-times air exchange, which is achieved by technical ventilation. Air inlet and extraction openings are protected from the weather and secured by fire protection flaps. Looking for a lithium room to suit your needs?

All safety-relevant components of the room system are recorded by sensors in the system control and stored for 12 months. Supplementary information on running times and maintenance intervals provides a comprehensive over- view. The modern, user-friendly control panel is connected to the high-per- formance controller via Modbus. This maintains its function even if the con- trol panel fails. The control software developed by DENIOS and coordinated hardware components are optimally designed for the application. The mail server included in the project scope of delivery is controlled via modem and enables fast intervention in the event of a fault by means of real-time alerts. The turnkey room system was developed by DENIOS at its production site in Bad Oeynhausen, North Rhine-Westphalia. This was immediately followed by transport, installation and commissioning, as well as customer training by the experienced DENIOS service personnel. DENIOS provided the lift- ing equipment and tools required for the process alongside the installation material and anchoring technology for fixing to the substrate, all of which were perfectly matched to the application. Only the on-site connections were made by the customer. F I R E E X T I N G U I S H I N G T E C H N O L O G Y I N T H E E V E N T O F A N I N C I D E N T .

The room system is equipped with a semi-fixed water extinguishing system for which DENIOS was responsible for project planning, installation and doc- umentation in accordance with VdS CEA 4001. Thermal runaway can be pre- vented by cooling the lithium storage medium as early as possible and for a sufficiently long time. If the reaction is already advanced, cooling can prevent or stop a chain reaction. In addition to the now sufficient storage capacity, the customer plans to add a test environment in the near future. This will initially comprise a room system with test chambers and a room system with measuring station. The DENIOS test rooms are perfectly suited to this purpose from p. 56.

Lithium energy storage devices such as batteries are now used in a wide variety of applications, including underwater robotics. Kraken Power GmbH, a special- ist in this field, deliberately wanted to invest in improved safety when handling lithium batteries in order to better meet the various requirements for storage and handling. The company chose DENIOS as its partner for this project. C H A L L E N G E A N D P R O J E C T . T H E P E R F E C T S O L U T I O N . Lithium batteries have a high risk potential. The causes of self-ignition are manifold and are mostly due to an invisible defect. The German Association of Insurers (VdS) recommends increased safety precautions, such as storage in separate fire protection areas, even for medium-power batteries and dam- aged energy storage devices. In order to ensure insurance cover and minimise the risk of fire, Kraken Power GmbH uses the special range of products from DENIOS SEfor the safe stor- age of lithium energy storage devices. Kraken Power also needed convenient handling for the separate storage of the lithium modules during production. In order to avoid unnecessary detours during storage, the SafeStore safety cab- inet with fire protection on both sides was selected, which could be placed directly at the production site. With the SafeStore from DENIOS, Kraken Power GmbH has received a new generation of safety cabinets with 90 minutes fire protection from inside and outside and equipment components specially designed for the safe storage of lithium batteries. What's special: conventional safety cabinets are only designed for fire pro- tection from outside to inside. SafeStore also protects against overheating or smoke development inside during storage. Fire resistance is 90 minutes from the inside to the outside and was proven by an additional fire test according to EN 1363-1. If a fire breaks out outside the cabinet, "SafeStore" also with- stands 90 minutes from the outside and is classified according to EN 14470-1 as Type 90. In addition, a liquid-tight floor spill pallet safely contains any leaks from burn- ing batteries. An integrated, self-closing door mechanism also ensures per- manent fire protection.

Storage and testing of lithium bat teries. Customised solutions. 60 | 61 C A S E S T U D Y . T E S T S T A N D F O R S T AT I O N A R Y E N E R G Y S T O R A G E D E V I C E S . Voltavision GmbH in Bochum, Germany is an independent R&D company, operating test equipment for high technology systems in the electromobility and renewable energy sectors. The size of the units tested ranges from lithium-ion batteries for electrical equipment right up to “large” energy storage systems. It was for these large applications that Voltavision and DENIOS developed a test room together, which had a customised test room volume and allowed testing of lithium energy storage devices over a wide temperature range. C H A L L E N G E A N D P R O J E C T . The energy revolution needs rethinking - in many respects. More and more energy is supplied by renewable sources such as wind farms or solar installa- tions. Energy is often produced at sites and at times of the day when it can't be used directly. This also means that electrical energy storage devices are becoming an increasingly relevant issue. Extensive tests, in which the effects of different environmental influences on the service life of the modules are analysed, are therefore all the more necessary. Although professional bodies have made many recommendations, there are no laws or regulations in the proper sense which constructors and operators can use as guidance. Safety designs are therefore based more on insights than standards. Based on the risk assessment, a separate fire compartment was necessary in this case, which was realized by enclosing the test stand. A fire-rated sys- tem which would resist a fire load from inside or outside for 90 minutes was required. Standard climate control chambers available on the market did not meet this requirement. W O U L D Y O U B E I N T E R E S T E D I N A S I M I L A R S O L U T I O N ? Do you need to test large lithium energy storage devices at various temperatures?

The result of this intensive cooperation is an innovative, turnkey solution offering repeatable measurement results at any time! All this was done with- out a separate climate chamber in the test room! Working together, Voltavision and DENIOS developed a fire-rated test stand (F 90/ REI 90) for stationary energy storage devices. Very large batteries, within the permitted test volume of up to 30 m³, can be subjected to defined thermal and electrical conditions. A temperature range of -20 °C to +60 °C, for example for artificial ageing processes, can be simulated under stand- ardised test conditions. The batteries are analysed for cycling stability and calendar life. In addition, a comprehensive safety design was taken into account in the planning. The inclusion of corresponding sensors allowed con- tinuous room monitoring. Whether it’s gas detection or temperature sensing - accident prevention is vital! A pressure relief panel in the roof area allows controlled pressure equalisa- tion in the event of an emergency. High performance technical ventilation also removes any harmful and potentially explosive gases. And if the worst should happen, contaminated cooling water is collected in a spill pallet. An acid resistant, anti-static inliner gives an additional level of safety. A sepa- rate connection is provided for emptying the WHG spill pallet. This ensures that cooling water can be properly disposed of.

Manufacturers of lithium-ion cells are expanding worldwide. In order not to waste valuable time when setting up new production facilities, the focus is on modular and turnkey solutions. A lithium cell manufacturer commissioned a test room from DENIOS to carry out product tests. The closed system had national technical approval, 90 minutes fire protection from inside and outside, a working environment that is climatically adapted to the sensitive technology and cus- tomer-specific equipment for demanding activities. I N T E G R A T E D D E H U M I D I F I C A T I O N M I N I M I S E S T H E R I S K O F F I R E . In order to ensure high product quality, the manufacturer plans to conduct regular tests. This also includes the dismantling of the lithium cells into their basic components. As contact with humidity in the air is sufficient for lithium compounds to catch fire, these tests must take place in a controlled working environment. In close cooperation with the customer, DENIOS has created a self-contained, technical room system for these demanding activities. A cus- tomer-specific solution has been developed on the basis of the standardised hazardous materials store WFP-X 22 Li-Ion, which already has F 90 fire pro- tection and flexible equipment options. The equipment is adapted to suit the planned activities and the room sys- tem is divided into an entrance and a dismantling area. The dismantling area is connected to a dehumidification system to keep humidity low and reduce the risk of fire to a minimum. Air conditioning generates a constant 20 °C +/- 2 K. A partition wall with a personnel air lock separates the two areas. Access authorisation is controlled by the level of humidity in the entrance area so as not to influence the climate in the dismantling room when the door is opened. An additional exit door in the working area serves as an escape route in an emergency. Four mobile hand-held fire extinguishers are mounted in different places for quick access. S A F E T Y I S I N E V E R Y C O M P O N E N T . All components of the test room are designed for safety. Windows in the doors and in the outer walls as well as video surveillance offer visual con- trol from outside, ensuring additional personal safety. The exterior cladding, including the windows and the cable and pipe breakthrough points, is fire-re- sistant (F 90). The floor is antistatic and resistant to chemicals. Emergency lighting makes it possible to complete work with care, even during power failures. Emergency signalling can be triggered by three manual call points and two fire detectors. Both audible and visible signals are given. In the event of an accident, further protective measures are provided by a complex control system.

Get in touch to arrange a consultation: 020 735 4960 w w w.denios.fi For the dismantling workstation, the customer opted for a DENIOS AT Com- pact worktable with air extraction. The work surface is specially made of plastic for this application. Powerful fans ensure an airflow from the envi- ronment towards the extraction vents. With air speeds up to 0.5 m/s at the entry, harmful substances and emissions in the work area are safely cap- tured, effectively retained and extracted. The Compact worktable’s folding front safety screen protects employees from emissions. A gas detector signals an alarm as soon as a hydrogen concen- tration is detected. Three additional worktables without air extraction for hazard-free activities extend the working area. Several 230 V sockets and dimmable LED lighting complete the individual room equipment. O N E O R D E R - F U L L S U P P O R T . As a rule, many different trades and contractors are involved in construc- tion projects. This means there is always a risk of coordination problems and information gaps. As a supplier and manufacturer of turnkey technical room systems, DENIOS has all the required expertise in-house. In the project described, the customer benefited from a central contact person right from the start. A project engineer coordinated the entire project for the customer, from requirements analysis to turnkey delivery. With direct communication and internal coordination between the various departments, the customer's requirements were recorded and implemented with no loss of information. The joint discussion made a decisive contribu- tion to the production of a meaningful and economical concept. The customer also made the decision to award the project to DENIOS because of our mar- ket leading position in hazardous material storage, our existing fire protection approvals and extensive references for storage and test rooms for lithium energy storage devices, going back many years.

When looking at the modern working environment, it's clear that digitalisation is bringing significant change to work processes, complexity is increasing and climate change is making us change our approach. But what kind of influence does this have on storage and process technology? We have set ourselves the goal of helping to promote the development of a modern work environment. In the new DENIOS equipment range for technical room systems you’ll find numerous options for creating a future-oriented workplace. Think Green: use your green fingers and increase the insulation value of your hazardous materials store at the same time. A living layer of insulation for the roof of the store makes a significant contribution to the environment, increasing insects, retaining rainwater and binding fine dust. The attractive appearance also increases the sense of well-being. The advent of digitalisation: keys, knobs, switches, paper? The modern world of work hasn’t been that way for a long time: digital access systems, touch panels, video monitoring, database services for condition monitoring or warehouse management and much more, have changed work processes, making them safer and more efficient. Digitalisation is also making its way into storage and process technology at DENIOS. D I G I T A L S E R V I C E S . The storage of hazardous substances is subject to strict regulations and laws for reasons of work safety and environmental protection. Planning, organising and operating a hazardous materials store entails a multitude of challenges and obligations for the operator. The digital services from DENIOS offer reliable and convenient support for these tasks. W W W . D E N I O S . F I

As an operator, you know that you must regularly check the proper condition of your fire-rated store, as required by law. This inspection must comply with the specific requirements of the Industrial safety regulation (BetrSichV) for the risk in question, e.g. in the case of fire and explosion hazards. DENIOS connect offers you optimum support so that you can complete all the necessary checks properly - with the help of practical data transmission and intelligent condition monitoring solutions. Regardless of whether you are on the move on your company premises or on standby duty: the active DENIOS connect sensors permanently monitor the status of your technical room system. If there is a leak, smoke or other fault, DENIOS connect sends you an alarm - in real time as an SMS or e-mail on your smart- phone, tablet or desktop PC. You can react immediately, saving valuable time and any subsequent costs for rectifying the situation. The incident report docu- menting the event can be easily downloaded as a PDF. In addition, a reminder function ensures that you never miss a maintenance appointment.

DENIOS connect is a user-friendly, cloud-based web app. It has been tested according to the latest security criteria and complies with the strict rules of the General Data Protection Regulation. NarrowBand IoT, currently the most efficient mobile network technology for applications such as DENIOS con- nect, is used for data transmission. Independent of your company network, you will have access to the relevant data and alarm messages from your hazardous materials store at any time and from practically anywhere in the world. Narrowband IoT is based on LTE and uses the associated 3GPP secu- rity mechanisms. The technology is specially designed for smaller data vol- umes and dispenses with unnecessary LTE functions. It therefore offers par- ticularly cost-effective and reliable mobile communication.

Due to its sturdy construction, the worktable is optimally designed for use in a tough industrial environment and is also ideal for use in a laboratory. F I R E P R O T E C T I O N . E A S E O F U S E . The liquid-permeable work surface of the test bench is mounted above a water basin and can be lowered into the basin by a motor in an emergency. High-quality actuators ensure a rapid lowering speed of up to 50 mm/s. The lithium battery is covered and cooled by the water bath. The water can flow out of the basin via the centrally located drain with stopcock. S M O K E E X T R A C T I O N . The smoke extractor can be switched on in an emergency or triggered by a smoke detector. Alternatively, the workstation can be permanently ventilated to provide continuous employee and room protection. The horizontal displacement flow applied allows the air to flow from the inlet opening to the extraction vents. This ensures an air speed of up to 0.5 m/s at the free cross-section at the inlet opening. In this way, improved workplace protection for both people and the room can be ensured.
