Rated 3-A:10-B:C and UL/ULC Listed, it delivers reliable suppression across Class A (wood, paper, cloth), Class B (flammable liquids and gases), and Class C (electrical equipment) fire hazards. The unit is manufactured to ANSI/UL 299, ANSI/UL 711, CAN/ULC-S504, and CAN/ULC-S508 standards and carries U.S.C.G. approval, making it suitable for marine and vehicle mounting as well as standard wall installation. With a 6-year warranty and a temperature range of -65°F to 120°F, it is built to perform in demanding environments.

Strike First ABC Series — Full Model Comparison

The SF-ABC310 stands apart from single-class extinguishers by covering Class A, B, and C hazards in a single compact unit, eliminating the need for multiple extinguishers on a job site. Its modified universal valve body accepts both pin and fork wall hooks, and its U.S.C.G. approval extends its utility to marine and vehicle applications — a versatility that single-rated units cannot match. The super durable polyester powder paint finish with superior corrosion resistance and waterproof stainless steel gauge ensure long service life in harsh construction environments.

Key Features & Benefits

Modified Universal Valve Body

The valve body accepts both pin and fork wall hooks, giving contractors flexibility in mounting configuration without requiring additional hardware. This simplifies installation across a variety of job-site and vehicle bracket setups.

Steel Cylinder with Super Durable Polyester Powder Paint Finish

The steel cylinder is coated with a polyester powder paint finish engineered for superior corrosion resistance, protecting the unit in wet, dusty, or chemically active job-site conditions. This extends service intervals and reduces replacement costs over the life of the extinguisher.

Waterproof Stainless Steel Gauge

The stainless steel gauge is waterproof, ensuring accurate pressure readings are visible even after exposure to rain, wash-down, or high-humidity environments. Reliable gauge readability is critical for confirming the unit is charged and ready before an emergency occurs.

Reinforced Full-Grip Hardcoat Anodized Aluminum Handle

The handle is reinforced and features a full-grip hardcoat anodized aluminum construction, providing a secure hold under stress. For contractors wearing gloves or working in cold conditions, a positive grip can be the difference between effective deployment and fumbling during a fire event.

Oversized Pull Pin with Retaining Strap

The oversized pull pin with retaining strap is designed for easier and faster activation, reducing the time from grab to discharge. In a fire emergency, every second counts, and this design minimizes the chance of activation failure under pressure.

Color and Bar Coded Labels

Color and bar coded labels support accurate service tracking and inspection compliance. This is particularly valuable for contractors managing multiple extinguishers across job sites who need to maintain NFPA 10 service records efficiently.

Complies with NFPA 10 Standard and Meets D.O.T. Requirements

Compliance with NFPA 10 and D.O.T. requirements means the SF-ABC310 satisfies the regulatory standards most commonly required by general contractors, site safety officers, and insurance inspectors. Having a compliant unit on site reduces liability exposure and simplifies safety audits.

90% MAP Agent

The 90% mono ammonium phosphate (MAP) dry chemical agent is highly effective across all three fire classes, leaving a residue that can be cleaned up after use. This high MAP concentration maximizes suppression effectiveness per pound of agent carried.

Common Applications

Construction Job Sites

Job sites generate Class A combustibles (wood framing, paper, insulation) and Class B hazards (fuels, solvents, adhesives) alongside energized electrical equipment — all covered by the SF-ABC310's 3-A:10-B:C rating.

Vehicles and Equipment Cabs

U.S.C.G. approval and vehicle/marine bracket compatibility make the SF-ABC310 suitable for mounting in trucks, heavy equipment cabs, and service vehicles where a compact, multi-class extinguisher is required.

Marine and Watercraft Applications

U.S.C.G. approval (Type A Size II, Type B:C Size I) qualifies this unit for use aboard vessels where Coast Guard-approved fire suppression equipment is mandated.

Electrical and Mechanical Rooms

The Class C rating makes the SF-ABC310 appropriate for placement near electrical panels, generator rooms, and mechanical equipment areas where energized equipment fire risk is present.

Workshops and Storage Areas

Facilities storing flammable liquids, gases, or combustible materials benefit from the combined Class A and B coverage, providing broad protection from a single mounted unit.
