High rack storage shelves are up to 50m high and are mostly designed for the intake of Europallets. Their capacity ranges from a few thousand to several hundred thousand pallet storage positions. On a very small surface area they offer space for extremely large quantities of goods and products. Between every two rows of storage shelves there is an alley in which rack feeders move up and down.

• Rapid spreading of fire in a vertical direction due to stacked pallets
• Chimney effect, i.e. flames and fire gases are drawn upward through the shafts

Sprinkler systems have been proven to work well in high rack storage facilities. In the conventional version, sprinklers are installed both under the ceiling and in the shelves. However, the installation of shelf sprinklers is rendered unnecessary if ESFR (Early Suppression Fast Response) sprinklers, which are installed only in the ceiling, can be deployed. Fire detection systems for the early detection of fires are also used to supplement sprinkler systems in high rack storage facilities. In these cases, Minimax recommends the use of HELIOS AMX5000 aspirating smoke detectors with a vertical installation of the suction lines in the shelves and mounting the evaluation units in easily accessible locations. The advantage of such a solution over punctiform smoke detectors is, for example, that they can be serviced very easily without having to interrupt business operations.

As a rule, paper rolls are stored in block storage facilities. Some warehouses are equipped with mechanical gripping systems - in other words, automatic paper roll depots.

• Chimney effect through shafts between the paper rolls
• The use of water as an extinguishing agent is impeded in cases where absorbent sanitary paper is stored.

In principle, the same fire protection systems described for block storage facilities can be used in these cases too. Protection concepts based on ESFR sprinklers or – in the case of warehouses with greater heights – a carbon dioxide extinguishing system are viable alternatives for situations where the storage of absorbent sanitary paper prevents the use of water-based fire extinguishing systems. In this case, too, carbon dioxide has the advantage – compared to other extinguishing gases – that it is also suitable for fighting deep seated smoldering fires. In large-dimension storage areas that require large quantities of carbon dioxide, we recommend storing the extinguishing agent in low-pressure containers for reasons of cost. For automated paper roll depots, Oxeo Prevent fire prevention systems are a viable alternative. The system is triggered by a fire detection system, HELIOS AMX5000 aspirating smoke detector, to allow for early detection.

Refrigerated storage is widespread especially in the food industry and in the related, downstream commercial operations. The goods and products are stored for purpose at temperatures of up to -40 °C. The necessary heat insulation often consists of non-flammable or flammable insulation materials with varying fire performance, often in the form of sandwich elements. Rack storage is predominant in refrigerated storage facilities

• Dry air promotes the rapid spread of fire
• Additional fire loads when using flammable insulation material
• Extinguishing water without antifreeze additives will freeze over very quickly.

Oxeo Prevent fire prevention systems are the ideal solution for refrigerated storage facilities, since the conditions for their use — no permanent presence of people in the storage facility, a well-sealed building shell and very low infiltration of fresh air caused by bringing in and removing goods — are also required to maintain the desired temperature level. Moreover, they offer perfect protection for the storage of foodstuff that is sensitive to smoke and temperatures. Oxeo Prevent fire prevention systems are mostly used in combination with HELIOS AMX5000 aspirating smoke detectors with a highly sensitive setting to ensure earliest fire detection. Heated aspirating outlets ensure their proper operation in refrigerated areas. Though Oxeo Prevent can only prevent a smoldering fire from turning into an open fire, the fire and the cause of fire would remain permanently undetected in the absence of an earliest fire detection system. Alternatively, sprinkler systems can be installed in such conditions — here ideally fitted with ESFR sprinklers. If there is a sufficiently spaced, frost-free intermediate area above the ceiling available, we recommend pendent Viking ESFR dry sprinklers. Combined with a Minimax PipeGuard Antifreeze system, sprinkler systems can be used in refrigerated storage facilities at a temperature of up to -40 °C.

Server rooms are important, sensitive areas. In these rooms, data of high importance for business operations is stored, managed and exchanged over the network. The irretrievable loss of this data through a fire may have considerable economic consequences for productivity or even the future of a company.

• Overheating of technical equipment
• Defects such as short circuits
• Considerable damage even in the case of small fires

For small and medium-sized server rooms, the MX 1230 extinguishing system is the ideal solution. It gives residue-free extinguishing using the innovative FK 5-1-12 extinguishing agents and requires very little space. Oxeo inert gas extinguishing systems are ideal for large server rooms. The MX 1230 extinguishing system and Oxeo inert gas extinguishing systems are triggered, and fires are detected, by a fire detection system using a HELIOS AMX5000 smoke aspirating system.
