What Class Fire Extinguisher For Computers: Safeguarding Your Tech from Hazards

In the ever-evolving digital realm, our computers stand as the gateways to a world of information, innovation, and interconnected possibilities. However, in this electronic haven, lurking dangers can pose serious threats to our prized tech companions.  

What class fire extinguisher for computers? Class C fire extinguishers are suitable for computers and other electronic equipment. It is designed to extinguish fires caused by electrical equipment without causing harm to the devices.

Let’s unveil the perfect match for your valuable hardware. From smoldering circuitry to electrical fires, understanding the right class of fire extinguishers is crucial to protect against unforeseen mishaps.

What Class Fire Extinguisher For Computers

What Is a Class C Fire Extinguisher?

A Class C fire extinguisher is specifically designed to combat fires involving electrical equipment, such as computers, appliances, and power tools. These fires are fueled by electricity, making them extremely dangerous to extinguish with water-based extinguishers. 

Class C extinguishers use non-conductive agents, such as dry chemicals or carbon dioxide, to smother the fire and interrupt the electrical current. These extinguishers are essential in workplaces and areas where electronic devices are present to ensure safety. 

Why Use Type C Fire Extinguishers for Computers?

Here are the reasons why Type C fire extinguishers are the preferred choice for combating computer fires:

  • Non-Conductive Agents: Type C fire extinguishers use non-conductive agents, such as dry chemicals or carbon dioxide, which do not conduct electricity. This is crucial when dealing with fires on or near electrical equipment, as using water-based extinguishers could cause electrical shock hazards.
  • Electrical Fire Safety: Computers and other electronic devices can pose a significant risk of electrical fires due to the presence of live electrical currents. Type C extinguishers are safe to use on these fires, as they are specifically designed to interrupt the electrical current and smother the flames without further damage.
  • Minimal Residue: The extinguishing agents used in Type C fire extinguishers leave minimal residue, reducing the risk of damage to sensitive computer components and making cleanup easier.
  • Fast Response: In the event of a computer fire, a Type C fire extinguisher allows for a quick response, minimizing the potential spread of the fire and preventing further damage to the equipment.

How to Use Type C Fire Extinguishers During an Electrical Fire?

When facing an electrical fire, it is crucial to use a Type C fire extinguisher, designed specifically for such hazards. Follow these steps to safely and effectively deploy the extinguisher:

  • Assess the Situation: Ensure your safety and evacuate the area if the fire is spreading rapidly or beyond your control.
  • Verify Electrical Source: Confirm that the power to the affected area is turned off or disconnected to minimize the risk of electric shock.
  • Aim at the Base: Stand at a safe distance from the fire and aim the Type C extinguisher’s nozzle at the base of the flames, not at the electrical equipment directly.
  • Squeeze the Handle: Firmly squeeze the handle to release the extinguishing agent, typically a non-conductive substance like carbon dioxide (CO2).
  • Sweep the Flames: Using a sweeping motion, move the extinguisher’s nozzle from side to side to cover the entire fire until it is fully extinguished.
  • Monitor the Area: Even after extinguishing the flames, remain vigilant and watch for any signs of re-ignition.

The Danger of Using Other Types of Fire Extinguishers

There are several good reasons for opting for Type C and some crucial reasons not to use other types of fire extinguishers.

Type of Fire ExtinguisherPotential Danger for Computers
Class AIneffective against electrical fires, may cause damage to computer components due to water or foam.
Class BNot suitable for electrical fires, may not fully extinguish the fire, causing re-ignition.
Class DShould not be used on non-metal fires or computer-related combustibles, may lead to increased fire spread.
Class KNot appropriate for electrical fires, can cause damage to computer equipment.
Water-BasedSerious risk of electrical shock and potential damage to computer hardware.
CO2 (Carbon Dioxide)Safe for electrical fires, but may not fully extinguish larger computer-related fires. Risk of frostbite if mishandled.
Dry Chemical (ABC)Effective for most fires, but can leave corrosive residues damaging to computer components.
FoamCan damage computer hardware and electronics, best used for Class A fires not involving computers.


Selecting the appropriate class fire extinguisher for computers is paramount to ensuring the safety of individuals, protecting valuable electronic equipment, and effectively combating fire incidents involving live electrical circuits.

Always adhere to proper fire safety protocols and seek professional assistance when dealing with fire incidents.
