As a fire safety expert with years of experience in dealing with various fire incidents, I feel it's crucial to address the question of what should never be put on a grease fire. Grease fires are among the most dangerous types of fires in a kitchen setting, and they require specific knowledge to handle safely and effectively.

First and foremost, never use water on a grease fire. Water and oil do not mix, and when water is poured onto a grease fire, it can cause the oil to splatter and spread the fire rapidly. This can lead to a much larger and more dangerous situation.

Another common misconception is that you can use a metal lid to smother a grease fire. While covering a fire with a lid can help to cut off the oxygen supply, it's not always the safest or most effective method, especially if the fire is large or the lid is not large enough to completely cover the pan. Additionally, using a glass lid is not recommended as it can shatter due to the intense heat, potentially causing injury.

Pouring baking soda on a grease fire is another method that has been suggested. While baking soda can help to put out small grease fires by releasing carbon dioxide, it requires a significant amount to be effective. For larger fires, this method may not be sufficient, and attempting to use baking soda could be dangerous.

Using a Class B Dry Chemical Fire Extinguisher is often recommended as a last resort for grease fires. These extinguishers are designed to put out fires involving flammable liquids and gases, which includes cooking oils. However, they should only be used when absolutely necessary, as they can leave a residue that can contaminate food and make the kitchen unusable until it is thoroughly cleaned.

It's also important to note that you should never try to move a flaming pan or attempt to extinguish the fire with your hands. This can lead to severe burns and make the situation worse.

In addition to knowing what not to do, it's equally important to understand the correct steps to take when dealing with a grease fire:


1. Turn off the heat source immediately to prevent the fire from growing.
2. If the fire is small and manageable, carefully place a metal lid over the pan to smother the fire, ensuring that the lid is large enough to cover the entire pan.
3. Keep a safe distance and do not attempt to move the pan.
4. If the fire does not subside within a few minutes, or if it grows larger, evacuate the area and call emergency services.
5. If you have a fire extinguisher rated for Class B fires and you are trained in its use, you may consider using it as a last resort.

Remember, the best way to prevent a grease fire is to always be vigilant when cooking with oil. Keep the area around your stove clean, avoid overheating oil, and never leave a pan unattended.

Now, let's move on to the translation of the above response into Chinese.

作为一位拥有多年处理各种火灾事件经验的消防安全专家，我认为有必要回答关于在油脂火中不应该放置什么的问题。油脂火是厨房环境中最危险的一种火灾类型，它们需要特定的知识来安全有效地处理。

首先，也是最重要的一点，永远不要在油脂火上使用水。水和油不相溶，当水倒在油脂火上时，可能会导致油溅出并迅速扩散火势。这可能导致更大、更危险的情况。

另一个常见的误解是，你可以用金属盖子来闷灭油脂火。虽然用盖子覆盖火源可以帮助切断氧气供应，但这并不总是最安全或最有效的方法，特别是如果火势很大或者盖子不够大以完全覆盖平底锅。此外，不建议使用玻璃盖子，因为它可能会因为高温而破裂，可能导致受伤。

向油脂火上倒小苏打是另一种被建议的方法。虽然小苏打可以通过释放二氧化碳来帮助扑灭小的油脂火，但它需要大量的小苏打才能有效。对于更大的火，这种方法可能不够，尝试使用小苏打可能是危险的。

使用B类干化学灭火器通常被推荐作为油脂火的最后手段。这些灭火器设计用于扑灭涉及易燃液体和气体的火灾，包括烹饪油。然而，它们应该只在绝对必要时使用，因为它们可能会留下残留物，污染食物并使厨房在彻底清洁之前无法使用。

同样重要的是要注意，你不应该试图移动燃烧的平底锅或用手扑灭火焰。这可能导致严重烧伤并使情况变得更糟。

除了了解不应该做什么之外，了解处理油脂火时的正确步骤同样重要：


1. 立即关闭热源以防止火势增长。
2. 如果火势小且可控，小心地将金属盖子覆盖在平底锅上以闷灭火焰，确保盖子足够大以覆盖整个平底锅。
3. 保持安全距离，不要试图移动平底锅。
4. 如果火势在几分钟内没有减弱，或者变得更大，撤离该区域并呼叫紧急服务。
5. 如果你有用于B类火灾的灭火器并且你受过使用培训，你可能会考虑将其作为最后的手段使用。

记住，预防油脂火的最佳方法是在烹饪时始终保持警惕。保持炉灶周围的区域清洁，避免油过热，并且永远不要离开无人看管的平底锅。
