Final answer:
In the case of a kitchen grease fire, you should turn off the heat source and cover the pan with a lid to smother the fire, not pour water on it. Use a fire extinguisher if necessary and evacuate if the fire persists.
The correct option is B) Use a fire extinguisher.
Step-by-step explanation:
If you have a kitchen grease fire in a pan on a stove, you should indeed turn off the heat source first. The immediate reaction might be to pour water on the fire, but doing so with a grease fire is a dangerous mistake, as it can cause the fire to spread more rapidly.
The correct action to take would be to cover the pan with a lid or another pan to smother the fire, which cuts off the oxygen supply and helps to extinguish the blaze.
As a secondary measure if the fire is too large to be smothered, using a fire extinguisher specifically designed to fight grease fires (Class K in the US or Class F in Europe) is the appropriate option. Only after attempting these methods, if the fire does not subside, should you call 911 and evacuate the building.
A kitchen grease fire is unlike other fires because grease is a fuel that can spread if not properly managed. That's why water, which can cause hot grease to splatter, must never be used to try to extinguish it – this can lead to a larger, more uncontrollable fire, as seen in the scenario provided.
Additionally, it's crucial to be aware of how to handle flammable materials and fire safety equipment like extinguishers in various settings such as a kitchen or a laboratory. Knowing what to do beforehand can prevent panic and mitigate damage should an emergency arise.
The correct option is B) Use a fire extinguisher.
