What Is It?

Vorbeck O3™ is a 3% fluorine-free foam concentrate engineered to extinguish and control both Class A combustible fires and Class B hydrocarbon fuel fires. The foam is specifically formulated to provide effective fire suppression while eliminating intentionally added fluorinated chemicals, supporting evolving environmental requirements and operational needs.

How Is It Used?

Vorbeck O3™ is proportioned with water and discharged through approved firefighting equipment to generate finished foam. The resulting foam blanket suppresses vapors, cools burning materials, and helps prevent reignition.

Common applications include:

• Hydrocarbon fuel fires
• Industrial fire protection
• Municipal firefighting operations
• Airport emergency response
• Storage tank protection
• Vehicle and transportation incidents
• Wildland and structural firefighting operations requiring Class A foam

Who Uses It?

• Municipal fire departments
• Industrial fire brigades
• Petrochemical facilities
• Energy and utility operators
• Military installations
• Marine and port facilities
• Emergency response teams
• Fire protection contractors

Maintenance Information

• Store in original containers with covers securely closed.
• Protect from contamination and extreme temperatures.
• Periodically inspect concentrate and storage containers.
• Follow departmental foam testing and maintenance procedures.
• Verify proportioning equipment calibration according to manufacturer recommendations.
• Rotate stock following local inventory management practices.

Performance Characteristics

Vorbeck O3™ is engineered to provide effective foam performance across both Class A and Class B fire applications. The concentrate can be proportioned at rates ranging from 0.1% to 1.0% for Class A fires and 1.0% to 3.0% for Class B fires, offering flexibility for a variety of firefighting scenarios. The finished foam delivers an expansion ratio of 7:1 to 10:1 and a 25% drain time of 60 to 85 minutes, supporting foam stability, vapor suppression, and burn-back resistance during firefighting operations.
