10LB Ansul Redline Cartridge (FORAY)

The Ansul Red Line I-A-10-G-1 is a 10 lb cartridge-operated hand-portable fire extinguisher charged with FORAY (monoammonium phosphate) ABC dry chemical, featuring the Indicator Fill Cap as standard equipment. The "I" in the model designation identifies this as the Indicator Fill Cap variant — the fill cap pops up a red stem when the unit is pressurized, providing an immediate visual readiness check without requiring a separate gauge. Rated 1-A:20-B:C, it provides Class A, B, and C coverage in a 10 lb cartridge-operated platform built to the Red Line's industrial standard.

As part of the Red Line cartridge-operated family, the I-A-10-G-1 stores the nitrogen propellant in a separate external cartridge, keeping the agent tank at atmospheric pressure until activation. This eliminates the slow pressure loss that can silently compromise stored-pressure units during extended standby in demanding industrial environments. The carbon steel cylinder is finished with Ansul's polyester powder coat, and the unit can be recharged on-site without shop pressurization equipment. It carries a 12-year limited warranty and is approved by UL, ULC, FM, and USCG.

The Indicator Fill Cap: What It Does and Why It Matters

The Indicator Fill Cap (the "I" in I-A-10-G-1) is a pressure-indicating fill cap that provides a passive visual readiness check. When the nitrogen cartridge is installed and the unit is pressurized, a red stem protrudes visibly from the fill cap — confirming at a glance that the unit is charged and ready. When the unit is at atmospheric pressure (standby mode), the stem is flush. This allows inspectors and operators to confirm readiness in seconds during monthly visual checks without any tools or gauge reading. It is particularly useful in high-unit-count facilities and remote industrial installations where rapid inspection status is operationally important.

FORAY ABC Agent: Triple-Class Coverage

FORAY is monoammonium phosphate (MAP) dry chemical — Ansul's multipurpose ABC agent and the only dry chemical in the Red Line portfolio rated for all three standard fire classes:

• Class A (Ordinary Combustibles): MAP undergoes sintering at approximately 350°F, melting to form an oxygen-excluding crust over wood, paper, and textile fires that prevents deep-seated re-ignition after initial knockdown.
• Class B (Flammable Liquids): The fluidized chemical cloud interrupts the free-radical chain reaction in the flame zone, providing rapid knockdown on gasoline, oil, solvent, and fuel fires.
• Class C (Electrical Equipment): The non-conductive agent allows safe suppression of energized electrical panels, motors, and control systems without risk of electrical shock to the operator.

Red Line Platform Features

• Cartridge-Operated Reliability: Nitrogen propellant stored separately — agent tank at atmospheric pressure until activation, eliminating slow-leak pressure loss and making every moving part accessible for annual maintenance inspection.
• Carbon Steel Cylinder: Tough carbon steel shell with polyester powder coat resists impact, vibration, and corrosion. Meets or exceeds ANSI/UL 299 and 711 or ULC S504 and S508.
• Field Recharge: Can be recharged on-site by a certified technician using Ansul-approved modified technical FORAY agent (pail part no. 434906). No shop pressurization equipment required.
• 12-Year Limited Warranty: Ansul's 12-year limited warranty from date of delivery.

The I-A-10-G-1 is the right specification for mixed-hazard industrial environments where the Indicator Fill Cap provides a meaningful inspection efficiency advantage:

• High-Unit-Count Facilities: Manufacturing plants, warehouses, and large industrial campuses where monthly inspection of many extinguishers benefits from the cap's instant visual confirmation of pressurization status.
• Remote Industrial Sites: Mining operations, oil and gas pumping stations, and construction sites where extinguishers may go longer between formal inspections and the indicator provides a quick self-check capability for operators.
• Paint Lockers and Dip Tanks: Mixed-hazard manufacturing environments where FORAY's ABC coverage addresses ordinary combustible, flammable liquid, and electrical fire risks from a single unit.
• Fuel Loading Racks and Pumping Stations: Industrial fuel handling areas where the Red Line's field recharge capability is essential and mixed fire classes are present.
• Trucks, Buses, and Fleet Vehicles: USCG approved with proper bracket for marine vessels. Also suitable for vehicle mounting in fleet and heavy equipment applications where ABC coverage is specified.

To maintain NFPA 10 compliance, the I-A-10-G-1 must follow a documented maintenance schedule:

• Monthly Visual Inspection: Verify the nitrogen cartridge safety seal is intact, the pull pin and tamper seal are in place, and the indicator fill cap red stem is not protruding (unit should be at atmospheric pressure at rest). Confirm inspection tags are current and the hose and nozzle are free of obstruction.
• Annual Maintenance: A certified technician must inspect all components, verify nitrogen cartridge condition, check hose assembly, and confirm FORAY agent has not packed. Document on the inspection tag.
• 6-Year Internal Examination: Full internal inspection per NFPA 10 including agent removal, cylinder interior inspection, and component replacement as needed. Recharge only with Ansul-approved modified technical FORAY agent (pail part no. 434906).
• 12-Year Hydrostatic Test: The carbon steel agent tank must undergo hydrostatic pressure testing per NFPA 10 and DOT requirements to verify structural integrity.

What is the difference between the I-A-10-G-1 and the standard RL-A-10-G?

Both are 10 lb FORAY ABC Red Line cartridge-operated units with the same 1-A:20-B:C rating and identical specs. The I-A-10-G-1 adds the Indicator Fill Cap — a fill cap that pops up a red stem when the unit is pressurized, providing an instant visual readiness check without any tools. Specify the I model when the inspection efficiency benefit of the indicator matters for your facility — particularly in high-unit-count or remote site installations.

Why does this unit have a lower B:C rating than the 20 lb and 30 lb FORAY Red Line models?

UL Class B ratings reflect the size of the burning fuel pan that a trained operator can suppress — a larger agent volume with a longer discharge time means a larger pan can be suppressed. The 10 lb model's 9-second discharge and 11-foot range result in a 1-A:20-B:C rating, while the 20 lb model achieves 40-B:C and the 30 lb model achieves 80-B:C. For applications where a higher B:C rating is required, specify the 20 lb or 30 lb FORAY model.

Can this unit be recharged with standard FORAY agent?

No. All Red Line Class A extinguishers must be recharged with Ansul's modified technical FORAY dry chemical (pail part no. 434906), specifically formulated for the Red Line platform. Do not substitute standard Sentry-grade FORAY agent — it will not maintain the unit's listed performance and may affect reliability.
