精萘又名萘（精），白色易揮發(fā)晶體，有溫和芳香氣味，粗萘有煤焦油臭味，閃點(diǎn)80℃，熔點(diǎn) 80.1℃ 沸點(diǎn)217.9℃，不溶于水，溶于無水乙醇、醚、苯，密度比水重，性質(zhì)穩(wěn)定，主要用于合成鄰苯二甲酸酐等。以往的衛(wèi)生球就是用萘制成的，但由于萘的毒性，現(xiàn)在衛(wèi)生球已經(jīng)禁止使用萘作為成分。

　　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. In the past, sanitary balls were made of naphthalene, but due to the toxicity of naphthalene, the use of naphthalene as an ingredient in sanitary balls is now prohibited.

　　精萘屬于4.1類危險(xiǎn)品即是易燃固體，應(yīng)密封貯存在陰涼處。對(duì)于此類貨物，公司通過以下方式進(jìn)行管控：一是入場(chǎng)前認(rèn)真檢查貨物包裝，確保無泄漏才允許入場(chǎng)；二是嚴(yán)格控制火源，確保場(chǎng)區(qū)內(nèi)消除一切火源；三是加強(qiáng)巡檢，時(shí)刻關(guān)注貨物狀態(tài)，確保無泄漏現(xiàn)象；四是利用先進(jìn)的紅外測(cè)溫系統(tǒng)對(duì)貨物進(jìn)行溫度監(jiān)控。

　　Naphthalene belongs to Class 4.1 dangerous goods and is a flammable solid. It should be stored in a sealed and cool place. For such goods, the company controls them through the following methods: firstly, carefully inspect the packaging of the goods before entry to ensure that there are no leaks before allowing entry; The second is to strictly control the source of fire and ensure that all sources of fire are eliminated within the site; Thirdly, strengthen inspections, constantly monitor the status of goods, and ensure that there are no leaks; The fourth is to use advanced infrared temperature measurement systems to monitor the temperature of goods.

　　即使精萘在場(chǎng)地發(fā)生貨物泄漏也不必驚慌，值班安全員在場(chǎng)地巡檢時(shí)發(fā)現(xiàn)疑似泄漏情況會(huì)立即報(bào)給控制中心，之后穿戴輕型防化服抵近偵查，確認(rèn)泄漏情況后，調(diào)度員會(huì)安排正面吊將該集裝箱搬移至應(yīng)急處理區(qū)，啟動(dòng)現(xiàn)場(chǎng)處置方案，一旦內(nèi)部有異常高溫，會(huì)啟用應(yīng)急噴槍進(jìn)行持續(xù)降溫，待消防隊(duì)趕來后，與消防隊(duì)配合滅火，根據(jù)精萘的理化性質(zhì)，優(yōu)選干粉或二氧化碳滅火。

　　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. When 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.
