Refined naphthalene, also known as naphthalene (refined), is a white volatile crystal with mild aromatic smell. Crude naphthalene has the smell of coal tar. The flash point is 80 ℃, the melting point is 80.1 ℃, and the boiling point is 217.9 ℃. It is insoluble in water and soluble in anhydrous ethanol, ether and benzene. Its density is heavier than water and its properties are stable. It is mainly used to synthesize phthalic anhydride. In the past, sanitary balls were made of naphthalene, but due to the toxicity of naphthalene, naphthalene has been banned as a component.

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。

Refined naphthalene belongs to class 4.1 dangerous goods, that is, flammable solid, which should be sealed and stored in a cool place. For such goods, the company controls them in the following ways: first, carefully check the goods packaging before admission to ensure that there is no leakage before admission; Second, strictly control fire sources to ensure that all fire sources are eliminated in the site; Third, strengthen patrol inspection, pay attention to the status of goods at all times, and ensure no leakage; Fourth, the advanced infrared temperature measurement system is used 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。

Even if the naphthalene does not have to panic at the site of the leakage of cargo, the duty guard will find the suspected leakage immediately after the site inspecting. The light duty protective clothing will be put in contact with the investigation to confirm the leakage. After that, the dispatcher will arrange the front crane to move the container to the emergency treatment area and start the on-site disposal plan.

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。通過以上措施的實(shí)施，我公司可以確保該貨物安全可控。

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 to extinguish the fire. Through the implementation of the above measures, our company can ensure that the goods are safe and controllable.
