Fire protection for automated high-bay warehouses

The effective alternative to sprinkler systems

A high density of goods packed into a tight space, easily combustible packaging material, and electrical equipment all increase the risk of fire in automated high-bay warehouses. High-bay warehouses’ typical structural design and high density of goods mean that fire outbreak or spread can result in enormous losses. When fires occur in high-bay warehouses, a chimney effect often occurs, which helps the fire spread rapidly into higher areas and accelerate the spread of the fire. Suppressing such fires is very difficult as well. They represent a danger to people, the environment, goods, and logistics processes.

Fires need oxygen, heat, and fuel to develop. Highly combustible packaging materials represent an ideal fuel source.

A high degree of warehouse automation is synonymous with an increased risk of fire, because, statistically speaking, technical defects and the resulting short circuits or equipment overheating can lead to fire outbreak. The carriers of fire risk in automated high-bay warehouses include conveyor belts, storage and retrieval machines, packaging machines, rolling doors, and building systems such as electricity, lights, and HVAC. As such, the fire protection requirements for automated high-bay warehouses are particularly high: planners need to ensure that fires will be detected immediately upon outbreak and prevented from spreading, so that stored goods are protected and delivery bottlenecks, downtime and resulting costs are avoided. The problem with conventional sprinkler systems is that they result in significant, costly extinguishing process-related and water damage, so downtime is unavoidable. WAGNER’s professionally engineered systems for high-bay warehouses represent an alternative to sprinkler systems, one relying on active fire prevention rather than damage control. With its OxyReduct® oxygen reduction system, WAGNER has established an innovative protective solution that minimises the risk of fire from the outset.

Risk minimisation and active protection

Fire prevention as a solution for partly or fully automated high-bay warehouses

The OxyReduct® active fire prevention system relies on preventing fires rather than damage control. The principle behind the system is a simple one: Feeding nitrogen into the protected area removes the supporting oxygen that any potential fires would need in order to spread.
