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 smell. Crude naphthalene has a Coal tar odor, 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 absolute ethanol, ether, and benzene. Its density is heavier than water, and its properties are stable. It is mainly used to synthesize Phthalic anhydride, etc. In the past, sanitary balls were made of naphthalene, but due to its toxicity, the use of naphthalene as a component is now prohibited in sanitary balls.

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。對于此類貨物，公司通過以下方式進(jìn)行管控：一是入場前認(rèn)真檢查貨物包裝，確保無泄漏才允許入場；二是嚴(yán)格控制火源，確保場區(qū)內(nèi)消除一切火源；三是加強(qiáng)巡檢，時刻關(guān)注貨物狀態(tài)，確保無泄漏現(xiàn)象；四是利用先進(jìn)的紅外測溫系統(tǒng)對貨物進(jìn)行溫度監(jiān)控。

Refined naphthalene belongs to Class 4.1 dangerous goods, which are flammable solids and should be sealed and stored in a cool place. For such goods, the company controls them through the following methods: firstly, carefully inspect the packaging of the goods before entering the site to ensure that there are no leaks before allowing entry; The second is to strictly control fire sources and ensure the elimination of all fire sources 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.

即使精萘在場地發(fā)生貨物泄漏也不必驚慌，值班安全員在場地巡檢時發(fā)現(xiàn)疑似泄漏情況會立即報(bào)給控制中心，之后穿戴輕型防化服抵近偵查。

Even if there is a cargo leakage of refined naphthalene on the site, there is no need to panic. The on duty safety officer will immediately report the suspected leakage to the control center during the site inspection, and then wear light chemical protective clothing to approach for investigation.

確認(rèn)泄漏情況后，調(diào)度員會安排正面吊將該集裝箱搬移至應(yīng)急處理區(qū)，啟動現(xiàn)場處置方案，一旦內(nèi)部有異常高溫，會啟用應(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。

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 to keep the temperature down. After the fire brigade arrives, the dispatcher 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 will be preferred to extinguish the fire. Through the implementation of the above measures, our company can ensure the safety and controllability of the goods.

精萘的用途與應(yīng)急措施相關(guān)實(shí)現(xiàn)就講解到這里了，希望您在使用前后能夠好好做工作，預(yù)防危險(xiǎn)的發(fā)生危害到自身以及周圍人員的安全，還有產(chǎn)品的使用疑惑或者需求就來我們網(wǎng)站http://www.456nba.com咨詢了解看看吧!
