ABC Dry Chemical Extinguishers

ABC extinguishers are multipurpose units designed for Class A (ordinary combustibles), Class B (flammable liquids), and Class C (energized electrical) fires. They are the traditional go-to choice for broad coverage in a single extinguisher.

• Best for: homes, offices, warehouses, vehicles, light industrial spaces
• Consideration: dry chemical agent leaves residue that requires cleanup
• Popular Buckeye formats: 2.5 lb, 5 lb, 10 lb, and 20 lb

CO2 (Carbon Dioxide) Extinguishers

CO2 extinguishers are designed for Class B and Class C fires. They discharge carbon dioxide gas and leave no residue, which is important where sensitive equipment must remain clean.

• Best for: electrical panels, server rooms, laboratories, clean commercial areas
• Consideration: not intended for deep-seated Class A fires
• Common sizes: 5 lb, 10 lb, 15 lb, 20 lb

Water (Stored Pressure) Extinguishers

Water extinguishers are Class A units intended for ordinary combustibles such as wood, paper, and cloth. They are economical and effective where flammable liquids and electrical hazards are not present.

• Best for: schools, churches, corridors, assembly spaces
• Do not use on: electrical equipment or grease fires
• Typical sizing: larger units for public areas and facilities

Wet Chemical (Class K) Extinguishers

Wet chemical extinguishers are engineered for commercial kitchen hazards involving cooking oils and grease. They cool burning oil and create a foam blanket that helps prevent re-ignition.

• Best for: restaurants, institutional kitchens, food trucks, catering operations
• Common requirement: often required by code near fryers and cooking lines
• Typical model: Buckeye Class K units designed for kitchen systems

How to Choose the Right Size

Extinguisher size affects discharge time and coverage. Small spaces and vehicles typically use 2.5 lb or 5 lb models. Commercial and industrial facilities often require 10 lb or 20 lb units to meet hazard levels and spacing requirements.

A proper extinguisher selection supports both safety and compliance.

UL Ratings and Code Compliance

UL ratings indicate extinguishing capability under standardized tests. Local fire codes and insurance requirements may dictate minimum ratings, spacing, and mounting height.

Mounting Hardware: What to Use

• Wall Hook: Standard fixed installation for offices, facilities, and warehouses
• Vehicle Bracket: Secure mounting for fleet vehicles and service trucks
• Specialty Mounts: Cabinets, marine brackets, or environmental requirements
