精萘是一种有毒的固态有机物，具有易燃和升华的特性。在处理精萘火灾时，应特别注意以下几点：

　　Naphthalene is a toxic solid organic compound with the characteristics of flammability and sublimation. When dealing with naphthalene fires, special attention should be paid to the following points:

　　灭火剂选择 ：

　　Fire extinguishing agent selection:

　　由于精萘与水反应，不能使用水灭火。

　　Due to the reaction between naphthalene and water, water cannot be used to extinguish fires.

　　使用泡沫灭火剂可能产生危险，因为泡沫中的水分可能与精萘反应。

　　The use of foam extinguishing agent may be dangerous because the moisture in foam may react with refined naphthalene.

　　使用干粉灭火器是较为安全的选择，特别是ABC类干粉灭火器，可以覆盖火源并隔绝空气。

　　Using dry powder fire extinguishers is a safer choice, especially Class ABC dry powder fire extinguishers, which can cover the fire source and isolate the air.

　　其他灭火方法 ：

　　Other firefighting methods:

　　使用沙土覆盖也可以隔绝空气，降低温度，从而扑灭火焰。

　　Covering with sand can also isolate the air, reduce temperature, and extinguish flames.

　　使用雾状水可以降低精萘的温度，但要注意不要直接将水射至溶融物上，以免引起流淌火灾或剧烈沸溅。

　　Using misty water can lower the temperature of refined naphthalene, but be careful not to directly spray the water onto the molten material to avoid causing flowing fires or severe boiling splashes.

　　注意事项 ：

　　matters needing attention:

　　在扑救精萘火灾时，应佩戴适当的防护装备，如呼吸防护装备。

　　When extinguishing naphthalene fires, appropriate protective equipment such as respiratory protection should be worn.

　　火场撤离时，应迅速并确保呼吸道通畅。

　　When evacuating from a fire scene, one should quickly and ensure that the respiratory tract is unobstructed.

　　若吸入精萘烟雾，应立即就医。

　　If inhaling naphthalene smoke, seek medical attention immediately.

　　请根据具体情况选择合适的灭火方法，并确保个人安全

　　Please choose the appropriate firefighting method based on the specific situation and ensure personal safety
