It is used especially in fires of combustible solid materials, natural area fires such as forests, wood, paper and tire industries where solid material fires frequently occur. Benefits of Class A Foam:
- Reflects radiant heat and is highly visible
- Insulates fuels and excludes oxygen
- Absorbs maximum energy due to large surface area
- Attaches to vertical surfaces and acts as a water reservoir
- Allows water to penetrate fuels due to low surface tension
- Used in CAFS – Compressed Air Foam Systems
