Survitec, a global leader in survival technology, has successfully conducted comprehensive performance tests on new alcohol-resistant fluorine-free firefighting foam concentrates. The results indicate that these new foam concentrates are compatible with marine mixing systems and prove that a safe transition from PFAS (Per- and PolyFluoroAlkyl Substances) based products is both feasible and technically sound for operational use on various vessel types. The recent performance tests are part of Survitec’s ongoing due diligence concerning the new fluorine-free formulas. Previous laboratory tests by Survitec’s fire safety specialists confirmed the foam’s stability and effectiveness across multiple types of fire sprinkler nozzles and burning media, even with challenging fuels such as methanol.
However, a unique challenge presented itself with the high viscosity of these new foam concentrates, as they utilize different active ingredients, making them denser than traditional formulations. Maciej Niescioruk, Product Manager for Foam Systems at Survitec, explained that standard foam proportioners are often not designed to accommodate this new type of fluid. Therefore, rigorous testing was essential to ensure compatibility and dosing accuracy. Survitec opted to modify existing systems rather than replace them entirely, leading to varied outcomes for different setups.
Some configurations needed significant redesigns to ensure accurate dosing. Moreover, suitable pump selection is critical. Standard centrifugal pumps designed for low-viscosity fluids may fail with the new non-Newtonian fluorine-free formulas, potentially leading to system malfunctions. The urgency for these modifications intensifies as new regulations, specifically the IMO’s MSC.532(107), will ban the use of foams containing PFOS from January 1, 2026, due to health and environmental concerns.
This transition to fluorine-free alternatives is crucial for shipowners and operators for compliance and safety reasons. Niescioruk highlighted that the new fluorine-free foams are particularly advantageous for chemical tankers and methanol-fuelled vessels, where both environmental performance and fire safety are crucial. Successful performance testing allows Survitec to offer a reliable solution, facilitating a compliant transition to fluorine-free technology. The findings are currently being incorporated into projects, including one in Turkey.
As PFAS restrictions tighten globally, Survitec’s testing results offer reassurance that compliance does not compromise safety. However, careful planning and OEM support are essential for successful implementation. Niescioruk advised that any substantial changes to these systems be approached cautiously, with ample time for engineering assessments and approvals. He emphasized the importance of early testing and collaboration with knowledgeable OEM partners to navigate the complex regulatory landscape.
