FIRE SAFETY | WATER MIST SUPPRESSION SYSTEM
FOGMAKER GAINS FM APPROVAL FOR FIRE-
SUPPRESSION SYSTEM Last September Fogmaker International announced it had received FM approval for its high pressure heavy duty mobile equipment (HDME) fire-suppression system. The testing and approval were performed with the company’s new Eco 1 suppressant
– a water-based liquid for use under high pressure that is 100% PFAS-Free and GreenScreen certified at the Silver level. The FM 5970 Approval adds to certifications, such as the UL mark, SPCR 197 and 199, and AS 5062:2016, that the company already held for its fire suppression systems for vehicles, machines, and enclosed spaces. The Sweden-based company develops, manufactures, and markets fire suppression
systems with high-pressure water-based mist for vehicles and machines. CEO Lars Alrutz said, in a in a statement, that the product had stood up to rigorous
testing and the FM Approval would allow Fogmaker to better serve its customers in the mining segment. He added: “This is a significant step towards achieving our vision of creating safer
environments globally.” Fogmaker has partners in more than 60 countries, two subsidiaries and over 350,000
systems installed. Mario Flores, key account manager and responsible for the Mining, Tunnelling and

Construction Equipment segment, said: “We’re not just certified, we’re approved at the highest level and verified by the most respected certification bodies in the world.”
SETTING A NEW STANDARD
The fire suppressions system described can simultaneously attack all three elements of the fire triangle: heat, oxygen, and fuel. They do so while offering the following features: ● Rapid Cooling and Re-Ignition Prevention - Unlike foam or powder-based alternatives, the fine cloud of water mist absorbs massive amounts of heat in seconds, reducing temperatures to prevent re-ignition, which is essential in confined tunnel environments.
● Environmentally Sustainable - Traditional suppression systems often leave corrosive residues or require extensive clean-up, leading to costly downtime. The PFAS-free ECO1 water-based fluid, certified by GreenScreen, is non-toxic, leaves
no destructive residues, and aligns with global sustainability initiatives.
● Compact, Scalable, and Versatile - The system’s compact design allows it to be installed in various applications, from TBMs and small locomotives used in tunnel works to transformers and ventilation shafts, which ensures that protection is not limited to vehicles alone.
A NEW CHOICE FOR TUNNEL OPERATORS For decades, tunnel operators have had only two main suppression options: powder-based systems or foam- based systems. The introduction of high-pressure water mist now provides a third option that combines rapid- fire suppression, cooling, and oxygen displacement in a way that traditional systems cannot match. The question is no longer whether fire suppression
is necessary. Regulations and safety demands have already determined those necessities. The real question, therefore, when seeking the best protection for people and assets while ensuring operational efficiency is: which system? Tunnel operators can choose from:
Right: Mario Flores
● Powder-based fire suppression, which creates extensive contamination, leading to high maintenance costs.
● Foam-based fire suppression, which offers limited cooling and is sometimes environmentally concerning.
● High Pressure Water Mist, which cools, displaces oxygen, and suppresses fuel—all in a single solution.
The high pressure, water mist fire suppression system has been rigorously tested and validated.
