Fire extinguishing foam concentrate Class A

Overview
Foam concentrates designed for suppression of Class A combustible-material fires. Suitable for structural, wildland and industrial firefighting involving wood, paper, coal, rubber and plastics. Formulated to reduce water surface tension for enhanced wetting and penetration while producing a dense foam blanket that insulates fuel from air.

Features

• Effective on deep-seated Class A incidents including tire, paper, coal, structure and wild fires.
• Reduces water surface tension to improve wetting and penetration into fuels.
• Foam solution forms a dense insulating blanket and adheres to vertical surfaces for structure protection.
• Proportioning ranges typically 0.1% to 1% for Class A firefighting concentrates.

Benefits

• Approved formulations available for wildland firefighting (e.g., US Forest Service where specified).
• Consistent performance for fire and vapor suppression through controlled formulation and quality processes.
