Final answer:
Class K extinguishers are best for fires in a deep fat fryer of a kitchen because they are specifically designed to combat fires involving cooking oils and fats.
Explanation:
A fire in a deep fat fryer of a dietary kitchen should be fought with a Class K extinguisher. Class K extinguishers are designed specifically for fires involving cooking oils and fats by releasing a wet chemical that helps cool the fire and prevent re-ignition. They are ideal for commercial cooking environments but can also be used in household kitchens. Using the wrong type of extinguisher, like water in a grease fire, can be very dangerous, as demonstrated by the anecdotal event where firefighters in Chicago faced a challenging situation. They tried to extinguish a kitchen fire by spraying water, but the fire would not go out, leading to a risky situation where they had to evacuate just before the floor collapsed. This exemplifies the importance of understanding the correct type of extinguisher to use for different classes of fires.
