Fire Classes: The Extra for Safety and Environment

For more than 100 years, we have been developing and producing top-class foam agents and special extinguishing agents for all fire classes, of outstanding quality for all requirements and areas of modern firefighting. 

Focus on environmental compatibility and sustainability in all fire classes
The responsible handling of the environment and its scarce resources poses high demands on modern fire protection. The development of environmentally friendly and efficient extinguishing agents based on renewable raw materials has been our focus since the early 1960s. With us, you receive not only a qualitatively outstanding foam agent with large reserves but also our expertise, support, accessibility, and commitment.

Brandklasse A-Schaummittel are designed for extinguishing solid fuel (class A) fires, such as wood, paper, textiles, coal, hay, cotton, some types of plastics, tyres.

The use of Class B foam agents can quickly and reliably extinguish fires involving liquid and liquefiable substances. Fuels of Class B must be differentiated into non-polar (not miscible with water) liquids (e.g., gasoline, diesel, kerosene, oil, etc.) and polar (miscible with water) liquids (methanol, ethanol, isopropanol, etc.). The polarity of the fuels is crucial for the selection of applicable foam agents.

Brandklasse F-Schaummittel are used to extinguish burning food grade oil and fat in private and commercial kitchens easily and safely.
