When fighting aircraft fires, it is crucial to keep the aircraft fuselage intact for as long as possible to maximize the time available for passenger escape and rescue. Therefore, the foam generated from vaPUREx® LV ICAO C 3% F-5 #7371 must not only quickly and reliably cover kerosene spills on the ground, but also be usable for cooling the fuselage. The resulting foam-water mixture foams up exceptionally well at foam pipes and nozzles, and the highly fluid foam quickly covers large spills. When the foam jet is directed at the fuselage, the cooling foam blanket forms on the outer shell. It flows downwards around the fuselage until it drips off, covering any remaining hotspots beneath or in the immediate vicinity of the fuselage. Thanks to its excellent foaming properties, foam coverage heights can be achieved that reliably cover kerosene spills even on uneven terrain away from the runway, quickly reducing heat exposure to the aircraft fuselage. We offer suitable user training for airports.

Airport fire trucks were historically designed for use with low-viscosity AFFF. Switching to a foam extinguishing agent manufactured without PFAS necessitates a system check. After the vehicle has been professionally cleaned, the foam extinguishing agent can be added. A field test allows for verification of the proportioning rate and the resulting foam quality. Sampling should be carried out under the most critical operating conditions, i.e., at minimum and maximum flow rates. Since vaPUREx® ICAO C 3% F-5 #7371 is a water-like, Newtonian foam extinguishing agent, all commercially available proportioning systems can dose the agent into the extinguishing water. Foam production and quality then depend on the nozzle used. If foam quality testing is not possible, we recommend using monitors with foam tubes. We have already achieved excellent results with many monitors using hollow jet nozzles. A fire-fighting foam must exhibit a minimum expansion rate while maintaining good flow properties. vaPUREx® LV ICAO C 3% F-5 #7371 allows for universal use with a wide variety of monitor and nozzle types, combined with maximum extinguishing performance. We offer vehicle inspections as a service. We also support conversion projects and conclude them with "foam user training.".

Worldwide, the ICAO standard applies to civil aviation. In Europe, EASA guidelines for the safe operation of airfields and airports are currently being introduced in parallel and as a supplement. For foam extinguishing agents, the certification standard according to ICAO Annex 14 applies, with a fire performance test according to Levels A, B, and C. Level C represents the highest performance requirement. A kerosene fire must be extinguished under test conditions with the smallest possible application rate within a specified time frame. Levels B and A allow for an increase in the application rate, but the maximum extinguishing time remains the same. Often, further standards are considered necessary. However, Mil-Spec or other NATO regulations are not a prerequisite for the use of foam extinguishing agents at civil airports. What is important is that the foam extinguishing agent is comprehensively tested and certified according to ICAO standards. Our vaPUREx LV ICAO C 3% F-5 #7371, with its achieved fire performance level of Level C, thus meets the most stringent requirement and allows airport operators to extinguish fires involving aircraft very quickly.

The first ban was imposed by EC 2006/122 and prohibited the placing on the market of products with a PFOS content of >50ppm from December 12, 2006 for “placing on the market”. Use was then permitted until June 27, 20011 for those extinguishing agents that had already been placed on the market before the date of entry into force (i.e. in the inventory of fire departments).

The WHG (Water Resources Act) requires every person within its scope of application to “avoid any detrimental change in the characteristics of water bodies” (WHG §5, Para. (1), 1.). The discharge of substances into bodies of water is generally subject to authorization and is bound by certain regulations. These are set out in various legal ordinances (including the AwSV (Ordinance on Installations for the Handling of Substances Hazardous to Water)). Since the introduction of the WHG, there has been a fundamental duty of care (which also includes the duty to provide active information) for the handling of substances hazardous to water, which includes all foam extinguishing agents and, in particular, extinguishing water.
