When extinguishing systems protect against risks involving e.g. plastics or flammable liquids, the use of foam agents is almost indispensable. Using those, many materials can be extinguished more efficiently or even at all.
However, these foams often contain per/poly-fluorinated chemicals persistent and toxic, so manufacturers and users are actively looking for environmentally friendly solutions; also because of the increasingly tightened legal limits.
fluorine-free biodegradable extinguishing foam
Such solutions are offered by Fabrik chemischer Präparate von Dr. Richard Sthamer GmbH & Co. KG: The Hamburg-based company has received the world's first VdS-Approvals for fully fluorine-free and virtually completely biodegradable extinguishing foam concentrates.
The products are approved to effectively protect against the above-mentioned risks.

Frank Bzdega, head of the VdS laboratories for water extinguishing systems, explains, "We congratulate the Sthamer team on these innovative and above all ecological developments.”
“Efficiency tests with sprinkler-system like foam application, laboratory analyses of the performance ratings according to EN 1568 and biological as well as chemical tests down to the molecular components prove optimal effectiveness with equally high application safety for humans and environment," concludes Frank.
