First Alert AF400 EZ Fire Spray — 18 oz Aerosol Extinguisher

The First Alert AF400 EZ Fire Spray provides 18-ounce aerosol fire extinguishing spray for residential kitchen and home fire first response — delivering First Alert's EZ Fire Spray formulation in the 18 oz single-unit format for household point-of-purchase placement in the kitchen, living area, or anywhere immediate fire suppression accessibility is the primary priority. The AF400 is the single-unit entry point for First Alert's EZ Fire Spray line — the 18 oz aerosol can that provides the EZ Fire Spray formula in one unit for households equipping a single location with accessible fire suppression, or evaluating the aerosol spray format before committing to multi-unit coverage. The aerosol spray format delivers First Alert's fire suppression agent in the intuitive deployment mechanism that household aerosol products provide: no pin to pull, no trigger to engage, no discharge technique to learn — aim at the base of the fire and spray, the same as any household spray product. First Alert's residential fire safety heritage brings brand confidence to the formulation: the same company that has manufactured smoke alarms for residential fire safety since the 1950s applies that fire safety focus to the EZ Fire Spray's formulation for residential first-response applications. The 18 oz size provides meaningful discharge volume for initial attack on small fires — sized for the kitchen stovetop fire scenario where a directed spray during the first seconds of ignition can suppress the fire before it spreads to adjacent surfaces. Single-unit purchase makes the AF400 the appropriate choice for households outfitting one location with kitchen-accessible fire spray, or for those who want to evaluate the aerosol fire spray format's fit for their kitchen and home fire safety approach before purchasing multi-unit coverage.

First Alert EZ Fire Spray: Single-Unit Kitchen Aerosol for Immediate First Response

Kitchen fires account for the largest share of residential structure fire incidents in NFPA statistics — and cooking fires that start small are fires that can be suppressed quickly if a fire suppression tool is immediately at hand. The window for effective first-response extinguishment is brief: a stovetop fire that is still contained to the burner and pan can be suppressed in seconds with a directed spray; the same fire ten seconds later, once it has reached the range hood, cabinet faces, and exhaust system, has grown beyond what any household aerosol can address. The First Alert AF400 positions fire suppression at the kitchen — in a format that fits there. The 18 oz aerosol can stores in a kitchen cabinet door, on a countertop, in an under-cabinet bracket, or in a pantry within seconds of the cooking area. It doesn't require a wall bracket installation, a mounting template, or a designated location with clearance for a cylinder — it stores like any other kitchen product of comparable size. When a stovetop fire ignites, the AF400 is immediately at hand without retrieval from another room, without operating a pin-and-trigger mechanism under stress, without technique that an untrained household member might not execute correctly. First Alert's residential fire safety expertise — smoke alarms, carbon monoxide detectors, and fire safety products for residential use — informs the EZ Fire Spray formulation for the kitchen fire scenarios where the AF400 is positioned. The 18 oz size distinguishes the AF400 from smaller aerosol formats: greater discharge volume means more spray available for initial attack on small fires, providing a larger margin for fires that require more than a brief burst to suppress. For the household establishing kitchen fire safety with a single-location spray product, or for those adding dedicated kitchen fire suppression alongside a traditional extinguisher mounted elsewhere in the home, the AF400 single unit provides First Alert's aerosol fire spray in the straightforward single-purchase format appropriate for one-location outfitting.

Compliance and Standards

• First Alert EZ Fire Spray — residential fire safety aerosol product
• NFPA 10 — portable fire extinguisher standard reference for residential kitchen fire preparedness

Real-World Benefits

18 oz single-unit provides immediate kitchen fire suppression with more agent volume than smaller aerosol formats — the larger discharge capacity of the AF400 compared to compact aerosol sprays means more agent available during initial attack on fires that require sustained spray to fully suppress.

First Alert brand formulation quality in aerosol spray format — the residential fire safety manufacturer behind First Alert smoke alarms applies the same fire safety focus to the EZ Fire Spray formulation, providing household confidence in the product's performance for kitchen fire first response.

Applications and Use Cases

• Kitchen countertop fire spray — AF400 single unit for primary kitchen fire first response — AF400 stored on countertop or under-cabinet in the kitchen for immediate deployment on stovetop, microwave, and small appliance fires where accessibility at the cooking area is the key first-response enabler
• Kitchen fire safety supplement — aerosol spray alongside traditional extinguisher elsewhere in home — AF400 for households with a traditional extinguisher in garage, hallway, or utility room who want dedicated kitchen-accessible spray suppression without relocating the primary extinguisher from its current location
• Single-location home aerosol fire spray — one unit for focused placement — AF400 for households outfitting a single high-risk location with aerosol fire suppression, where one unit in one location serves the primary fire preparedness need

Frequently Asked Questions

What is the difference between the AF400 and the AF400-2?

The AF400 is the single-unit version — one 18 oz EZ Fire Spray can for a single location. The AF400-2 is a two-pack — two 18 oz cans for multi-location coverage, typically one for the kitchen and one for the vehicle, at better per-unit pricing than two individual purchases. For households equipping one kitchen location, the AF400 single unit is the appropriate choice. For households wanting kitchen and vehicle coverage simultaneously, the AF400-2 two-pack provides both units in one purchase.

Can the AF400 be used on grease fires?

Aerosol fire sprays vary in their rated fire class coverage — review the product's specific fire class certifications on the packaging to confirm the fire types the AF400 is rated to address. For hot cooking oil and deep fryer fires (Class K), a K-class wet chemical extinguisher provides more appropriate suppression than aerosol sprays not specifically formulated for high-temperature oil fires, as water-based agents on burning hot oil can cause violent steam expansion that scatters burning material. The AF400 is primarily positioned for initial attack on small cooking fires — stovetop pan fires and small appliance fires in the early stages where immediate spray deployment can suppress the fire while it remains small. Always consult current product labeling for fire class ratings and use limitations.
