Foam fire extinguishers contain a specialized mixture of water and foam concentrate engineered to produce stable, effective foam. When activated, the foam is expelled under pressure, creating a thick protective layer that covers burning fuel surfaces. This advanced formulation not only smothers flames by cutting off oxygen supply but also provides significant cooling effects to reduce fuel temperature and prevent fire spread.

• Situation Assessment: Evaluate fire conditions before use. For large, rapidly spreading fires, or situations involving explosion risks or toxic fumes, evacuate immediately and contact emergency services.
• Extinguisher Selection: Ensure foam fire extinguishers are appropriate for Class A (combustible materials) and Class B (flammable liquids) fires. Not suitable for electrical equipment or flammable metal fires.
• Application Technique: Aim foam stream at the base of flames. Use sweeping side-to-side motion to ensure complete coverage of the fire area for maximum effectiveness.
