Question

In a commercial kitchen, which fire extinguisher is recommended to put out a grease fire. Question 1 options: Class A Class B Class K Class ABC

Answer 1

The recommended fire extinguisher to put out a grease fire in a commercial kitchen is Class K. Class K fire extinguishers are specifically designed for extinguishing fires involving cooking oils and fats.

Step-by-step explanation:

In a commercial kitchen, the recommended fire extinguisher to put out a grease fire is Class K. Class K fire extinguishers are specifically designed to extinguish fires involving cooking oils and fats, making them ideal for grease fires.

Unlike other fire extinguishers, Class K fire extinguishers use a special extinguishing agent that reacts with the hot cooking oils and fats to smother the fire and prevent reignition.

It is important to remember that using water to put out a grease fire can actually make the fire worse, spreading the burning grease and potentially causing injury. Therefore, it is crucial to have a Class K fire extinguisher readily available in a commercial kitchen to ensure the safety of the employees and the surrounding area.

Answer 2

Class B

Fire extinguishers with a Class B rating are effective against flammable liquid fires. These can be fires where cooking liquids, oil, gasoline, kerosene, or paint have become ignited. Two commonly used chemicals are effective in fighting these types of fires. Monoammonium phosphate effectively smothers the fire, while sodium bicarbonate induces a chemical reaction which extinguishes the fire.
