Answer 2

Answer:

Explanation:

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

• Water & 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

• Carbon 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

• Dry 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)
• Wet 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)

• Clean 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

• Dry 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

• Water Mist

This extinguisher takes away the heat of the fire only. Works For: Class A and C fires

• Cartridge Operated Dry Chemical

This extinguisher interrupts the chemical reaction of the fire, and creates a barrier between the oxygen and the fuel and, like the dry chemical extinguishers, works well on a variety of fire types. Works For: Class A, B and C fires
