In June 2025, the first water mist system in the world received FM Approvals certification for use in buildings classified as hazard category 2 (HC-2) and hazard category 3 (HC-3). The low-pressure water mist system from VID FIREKILL successfully passed tests according to the new FM Approvals Standard 5560 for water mist systems.
What does this certification bring?
Until now, it was only possible to use water mist systems approved by FM Approvals for HC-1 (low-risk) premises. The new certification allows systems approved by FM Approvals to be installed in buildings with a higher fire hazard level (HC-2 and HC-3). This opens up the possibility of protecting various types of facilities — from production and commercial operations to data centers.
Difference between classification HC-2 (hazard category 2) and HC-3 (hazard category 3)
HC-2 (medium hazard): Areas with moderate quantities of combustible materials —
for example, warehouses, mechanical workshops, or food processing facilities.HC-3 (higher hazard): Areas with higher quantities of combustible materials, plastics, or flammable liquids. Typical examples include industrial halls or food manufacturing plants.
Traditional sprinklers require a large volume of water to protect these categories effectively. Thanks to its design, VID FIREKILL’s water mist fire protection system consumes up to 50 times less water, while maintaining high efficiency in extinguishing fires.
Protecting data centers with water mist
One of the most significant modern applications of water mist systems is the protection of data centers. These facilities contain thousands of servers, cables, and sensitive IT equipment, where high energy density increases the risk of overheating and fire. A fire in a data center can cause massive financial losses — from data loss to prolonged operational downtime.
The low-pressure water mist system offers several benefits:
Fast and effective fire suppression.
Minimal water use, reducing the risk of damage to electronics.
Compatibility with battery systems (BBU), which have become standard components in data centers in recent years.
“Our mission is to protect assets and ensure business continuity through environmentally responsible solutions.
FM Approvals certification guarantees that our technologies meet the highest standards.” Alex Palle (CEO VID FIREKILL)
A New Era of Sustainable and Efficient Fire Safety
Water mist represents a modern and ecological approach to fire protection. It provides fast fire suppression, cools the environment, and minimizes damage to technology and equipment. Thanks to FM Approvals, it is now possible to use this highly efficient and safe fire protection solution — including in data centers and industrial facilities.
As VID FIREKILL continues its mission to protect property and prevent fire-related losses while promoting sustainable technology, its water mist fire suppression system is ready to set new standards for safety and efficiency. Together with 3MON and within the framework of the FireTec Concept, new and innovative solutions are being prepared for the future. Safety is no accident – it’s the result of collaboration.
