精萘又名萘（精），白色易挥发晶体，有温和芳香气味，粗萘有煤焦油臭味，闪点80℃，熔点 80.1℃ 沸点217.9℃，不溶于水，溶于无水乙醇、醚、苯，密度比水重，性质稳定，主要用于合成邻苯二甲酸酐等。

　　Refined naphthalene, also known as naphthalene (refined), is a white volatile crystal with a mild aromatic odor. Crude naphthalene has a coal tar odor, with a flash point of 80 ℃, a melting point of 80.1 ℃, and a boiling point of 217.9 ℃. It is insoluble in water but soluble in anhydrous ethanol, ether, and benzene. Its density is heavier than water and its properties are stable. It is mainly used for the synthesis of phthalic anhydride, etc.

　　以往的卫生球就是用萘制成的，但由于萘的毒性，现在卫生球已经禁止使用萘作为成分精萘属于4.1类危险品即是易燃固体，应密封贮存在阴凉处。

　　In the past, sanitary balls were made of naphthalene, but due to the toxicity of naphthalene, it is now prohibited to use naphthalene as a component. Fine naphthalene belongs to Class 4.1 dangerous goods and is a flammable solid. It should be sealed and stored in a cool place.

　　对于此类货物，公司通过以下方式进行管控：

　　For such goods, the company controls them through the following methods:

　　一是入场前认真检查货物包装，确保无泄漏才允许入场；

　　Firstly, carefully inspect the packaging of the goods before entering to ensure there are no leaks before allowing entry;

　　二是严格控制火源，确保场区内消除一切火源；

　　The second is to strictly control the source of fire and ensure that all sources of fire are eliminated within the site;

　　三是加强巡检，时刻关注货物状态，确保无泄漏现象；

　　Thirdly, strengthen inspections, constantly monitor the status of goods, and ensure that there are no leaks;

　　四是利用先进的红外测温系统对货物进行温度监控即使精萘在场地发生货物泄漏也不必惊慌，值班安全员在场地巡检时发现疑似泄漏情况会立即报给控制中心，之后穿戴轻型防化服抵近侦查，确认泄漏情况后，调度员会安排正面吊将该集装箱搬移至应急处理区，启动现场处置方案，一旦内部有异常高温，会启用应急喷枪进行持续降温，待消防队赶来后，与消防队配合灭火，根据精萘的理化性质，优选干粉或二氧化碳灭火。

　　Fourth, the advanced infrared temperature measurement system is used to monitor the temperature of the goods. Even if refined naphthalene leaks at the site, there is no need to panic. The safety officer on duty will immediately report the suspected leakage to the control center when patrolling the site, and then wear light chemical protective clothing to approach the control center for investigation. After confirming the leakage, the dispatcher will arrange a front crane to move the container to the emergency treatment area, and start the on-site treatment plan. Once there is abnormal high temperature inside, the emergency spray gun will be used for continuous cooling. After the fire brigade arrives, it will cooperate with the fire brigade to extinguish the fire. According to the physical and chemical properties of refined naphthalene, dry powder or carbon dioxide is preferred for extinguishing.

　　通过以上措施的实施，我公司可以确保该货物安全可控。

　　By implementing the above measures, our company can ensure the safety and controllability of the goods.
