What type of fire extinguisher would be used in a kitchen environment for grease fires?

In a kitchen environment, particularly for dealing with grease fires, a Class B fire extinguisher is the appropriate choice. Class B extinguishers are specifically designed to combat flammable liquids and gases, which includes cooking oils and greases that can ignite during cooking.

Grease fires burn at high temperatures and can be particularly dangerous if not handled correctly. Class B extinguishers contain agents like foam, CO2, or dry chemical, which are effective in suffocating the fire and preventing it from spreading. It's crucial to avoid using water on grease fires, as this can cause the flames to spread rapidly. Class B extinguishers help safely extinguish such fires by breaking the fire's triangle—removing fuel, oxygen, or heat from the equation.

Using the correct type of extinguisher is essential for safety in these situations, making Class B the optimal choice for a kitchen environment.
