Amerex Powder Fire Extinguisher (5 lbs, 10 lbs, 20 lbs)

Description

Product Overview

Amerex powder fire extinguishers use a dry chemical powder — typically mono ammonium phosphate — as the extinguishing agent. When discharged, the fine powder coats burning materials, interrupting the chemical reaction of a fire and preventing further combustion. This type of extinguisher is often referred to as an ABC fire extinguisher due to its effectiveness against:

• Class A – Ordinary combustible materials: wood, paper, textiles

• Class B – Flammable liquids: grease, gasoline, oils, solvents

• Class C – Electrical fires: energized electrical equipment

Amerex operates under industry‑trusted safety standards such as UL (Underwriters Laboratories) and FM Global approvals, ensuring proven quality and performance.

Key Features

1. Multipurpose Dry Chemical Agent

Amerex powder extinguishers use high‑quality dry chemical that provides fast thermal interruption, making them effective against multiple fire types (A, B, C).

2. Durable Construction

Each extinguisher features a rugged steel cylinder with a corrosion‑resistant exterior and durable finish designed for harsh environments.

3. UL/FM Certified

Amerex extinguishers are often UL listed and FM approved, meeting key safety and performance standards used in fire protection worldwide.

4. Pressure Gauge

A built‑in pressure gauge on every unit allows users to quickly check whether the extinguisher is within operating pressure range — ensuring readiness at all times.

5. Easy Operation

Amerex units are designed for straightforward use with a large handle, safety pin, and squeeze lever. The discharge hose or nozzle provides controlled dispersion of the powder.

6. Universal Mounting Bracket

Units come with a wall bracket or mounting strap, making it simple to install the extinguisher in visible and accessible locations.

Applications

Amerex powder fire extinguishers are suitable for a wide range of environments:

Residential

• Homes and apartments

• Garages

• Storage sheds

Commercial

• Offices and retail spaces

• Restaurants

• Hotels and hospitality

Industrial

• Warehouses

• Manufacturing facilities

• Workshops

Public Places

• Hospitals

• Schools and universities

• Airports and transit stations

Their versatility makes them a popular choice for general fire protection needs.

How They Work

Powder fire extinguishers suppress flames by performing several actions:

• Cooling the fuel surface
• Coating the fuel with a barrier between oxygen and heat
• Interrupting the chemical reactions occurring in the fire

When the safety pin is pulled and the handle squeezed, pressurized gas forces the dry chemical powder through the nozzle or hose. The agent travels toward the fire and forms a protective layer over the burning surface, quickly reducing flame intensity.

Safety & Proper Usage

Use the PASS method when operating:

1. P – Pull the safety pin

2. A – Aim at the base of the fire

3. S – Squeeze the handle to discharge

4. S – Sweep the nozzle side to side

Always aim at the base of the fire rather than the flames for more effective suppression.

Maintenance & Inspection

Proper maintenance includes:

•  Monthly visual inspection (gauge check, corrosion, damage)
•  Annual professional servicing
•  Checking mounting brackets for integrity
•  Recharging after any use

Powder extinguishers may require recharging if the pressure drops below normal range, even if unused.

Advantages

• Versatile — effective on A, B, C fires

• Fast‑acting

• Cost‑effective

• Wide range of sizes

• Durable and long‑lasting

• No special training required for basic operation
