How should a grease fire be put out?

• A. With water
• B. With a lid, baking soda/salt or fire extinguisher
• C. By throwing flour on it
• D. With a fire blanket

Answer: (B)

A grease fire should be extinguished by covering it with a lid or using substances like baking soda or salt, or by employing a fire extinguisher specifically designed for that type of fire. The reason for this method is that water can cause the flames to spread, as it reacts violently with the hot grease. Covering the fire with a lid can help suffocate it by cutting off the oxygen supply, and baking soda or salt can help smother flames because they do not ignite and can absorb some of the heat. Fire extinguishers labeled for grease fires (Class K or Class B) are also crucial tools that can effectively put out such fires safely.

Using flour is dangerous, as it is flammable and can actually worsen the fire situation. A fire blanket may help in certain circumstances by smothering smaller fires but is not the most effective or recommended method for grease fires specifically. It's essential to understand the right tools and techniques to tackle different types of fires to prevent further danger and damage.
