What Is Inside A Fire Extinguisher Ball

A fire extinguisher ball, also known as a fire suppression ball, is a relatively new innovation designed to provide quick and easy fire suppression in emergency situations. The device is typically small in size, making it convenient to store in various locations for immediate access. Let's explore what is inside a fire extinguisher ball and how it works.

What Is Inside A Fire Extinguisher Ball

Components Inside a Fire Extinguisher Ball:

  1. Outer Shell:
    • The outer shell of a fire extinguisher ball is usually made of a lightweight, durable material such as hard plastic or glass-reinforced plastic (GRP). This shell is designed to withstand impact and heat to protect the contents inside.
  2. Fire Suppressant Powder or Chemical:
    • The main active ingredient inside a fire extinguisher ball is a fire suppressant powder or chemical. This substance can vary depending on the manufacturer and the intended use of the ball. Common substances used include monoammonium phosphate, sodium bicarbonate, or other proprietary powders that are effective against Class A, B, and C fires.
  3. Activation Mechanism:
    • Fire extinguisher balls are designed to activate automatically in the presence of flames. They typically have an activation mechanism such as a fuse or a heat-sensitive element inside. When exposed to high temperatures, this mechanism triggers the ball to burst open and release its contents.
  4. Fuse or Heat Sensor:
    • A fuse or heat sensor inside the ball detects the temperature rise associated with a fire. This triggers the activation process, ensuring that the fire extinguisher ball deploys its suppressant effectively when needed.
  5. Dispersal Mechanism:
    • Once activated, the fire extinguisher ball disperses the fire suppressant powder or chemical rapidly in the surrounding area. The dispersion is designed to cover a wide area quickly, extinguishing the flames and reducing the oxygen supply to the fire.

How It Works:

  • Automatic Activation: When a fire breaks out and reaches a certain temperature threshold, typically around 70-90 degrees Celsius (158-194 degrees Fahrenheit), the fire extinguisher ball activates on its own.
  • Rapid Deployment: Upon activation, the ball bursts open within 3-5 seconds and disperses the fire suppressant powder or chemical over an area of approximately 3-5 cubic meters (about 100-175 cubic feet).
  • Effectiveness: The fire suppressant material inside the ball works by smothering the flames and interrupting the chemical reaction of the fire, thereby extinguishing it quickly. This makes fire extinguisher balls effective for controlling small to moderate fires in homes, offices, workshops, and other enclosed spaces.


  • Ease of Use: No training is required to use a fire extinguisher ball; simply place it near a potential fire hazard and it will activate automatically if needed.
  • Compact and Portable: Fire extinguisher balls are small and lightweight, making them easy to store and deploy in various locations.
  • Maintenance-Free: Unlike traditional fire extinguishers, fire extinguisher balls require minimal maintenance and have a long shelf life (usually 5-10 years).

In conclusion, a fire extinguisher ball contains specialized fire suppressant powder or chemical inside a durable outer shell. It operates through an automatic activation mechanism triggered by heat, providing rapid and effective fire suppression in emergency situations. This innovative device continues to gain popularity for its simplicity, effectiveness, and convenience in fire safety measures.

Frequently Asked Questions

A fire extinguisher ball is a spherical device designed for fire suppression. It contains fire suppressant powder or chemical inside a durable outer shell and is designed to activate automatically when exposed to flames.

Fire extinguisher balls work by automatically activating when they detect a certain temperature (typically around 70-90 degrees Celsius). Upon activation, the ball bursts open and disperses the fire suppressant material, smothering the flames and extinguishing the fire.

Fire extinguisher balls are effective against Class A, B, and C fires. Class A fires involve ordinary combustibles like wood and paper, Class B fires involve flammable liquids, and Class C fires involve electrical equipment.

Fire extinguisher balls should be placed in areas prone to fire hazards, such as kitchens, workshops, electrical panels, and near any potential sources of ignition. They should be mounted or placed in a location where they are easily accessible and visible.

Fire extinguisher balls require minimal maintenance. They should be checked periodically to ensure they are not damaged or expired. Most fire extinguisher balls have a shelf life of 5-10 years and do not require refilling or servicing during this period.
