Kitchen Fire #3

Kitchen Fire show #3  Quick Tip


Put out the fire by putting a lid on it. Shake baking soda on it. "The worst thing you can do is throw water on it." You should never transfer flaming alcohol from one pan to another. “When you go to pour that, the flame is still gonna want to come up.

Types of Fires

four components required for a fire to start – heat, fuel, oxygen, and chemical reaction – and fire extinguishers are designed to put out a fire by removing one or more of these elements.

Before we get to the different types of fire extinguishers, it’s important to understand the different types of fires that these extinguishers are designed to fight. 

  • Class A – a fire started with normal combustibles such as wood, paper, and cloth
  • Class B – a fire started with flammable and combustible liquids and gases such as gasoline and paints
  • Class C – a fire started by energized electrical equipment such as a short circuit in power transmission cables
  • Class D – a fire started by flammable metals such as sodium, potassium, and lithium
  • Class K – kitchen fires

Types of Fire Extinguishers

Many homes and offices will either use general-purpose or kitchen extinguishers, but other environments, like laboratories or warehouses, might need more specific extinguishers.

fire extinguisher Water-FoamWater & Foam

The water component of this extinguisher removes the heat of the fire, while the foam component removes the oxygen.

Works For: Class A fires only

 

fire extinguisher Carbon-DioxideCarbon Dioxide

Carbon dioxide replaces the fire’s oxygen and, as the gas is contained under pressure it creates a cold discharge upon release, which removes the heat of the fire too.

Works For: Class B and C fires

 

fire extinguisher Dry-ChemicalDry Chemical

This extinguisher removes the chemical reaction of a fire and is the most used of all fire extinguishers because of its versatility across multiple classes.

Works For: Class A, B, and C fires (multi-purpose); Class B and C (ordinary)

 

fire extinguisher Wet-ChemicalWet Chemical

This extinguisher removes heat and creates a barrier between oxygen and fuel so a fire cannot be re-ignited. The chemical is sprayed as a mist, cooling the fire’s heat and creating a blanket effect over the fuel.

Works For: Class K fires (particularly good for fires started by oils or fats)

 

fire extinguisher Clean-AgentClean Agent

Also called Halogenated extinguishers, these include halon agents and new, less ozone depleting halocarbon agents, which extinguish a fire by interrupting its chemical reaction.

Works For: Class B and C fires

 

fire extinguisher Dry-PowderDry Powder

This works similarly to the dry chemical extinguisher as the powder separates the fuel from oxygen or removes the heat, but this extinguisher is only used to fight combustible metal fires.

Works For: Class D fires

 

fire extinguisher Water-MistWater Mist

This extinguisher takes away the heat of the fire only.

Works For: Class A and C fires

 

fire extinguisher Cartridge-OperatedCartridge Operated Dry Chemical

This extinguisher interrupts the chemical reaction of the fire, and creates a barrier between the oxygen and the fuel and, as the dry chemical extinguishers, works well on a variety of fire types.

Works For: Class A, B, and C fires

It’s important to use the right extinguisher for the type of fuel – using the incorrect one can allow a fire to re-ignite, even when it seems to have been put out successfully. We’ve put together a simple chart to help you choose the right extinguisher for your fire needs.
