精萘作为一种具有特殊性质的化学品，其储存需严格遵循安全规范，结合自身特性做好全方位防护，以避免发生安全事故。

　　As a chemical with special properties, refined naphthalene must be stored strictly in accordance with safety regulations and protected in all aspects based on its own characteristics to avoid safety accidents.

　　储存容器的选择是基础。精萘为白色晶体，易升华，且具有可燃性，因此需选用密闭性良好的容器，如镀锌铁桶或陶瓷罐，容器盖需配备密封垫圈，防止萘蒸气挥发。容器应无破损、锈蚀，内壁光滑无毛刺，避免精萘晶体在储存过程中因摩擦产生静电。对于大剂量储存，可使用专用的封闭式储罐，储罐材质需耐萘的轻微腐蚀，接口处采用螺纹加密封胶的方式密封，定期检查密封性能，防止蒸气泄漏。

　　The selection of storage containers is fundamental. Naphthalene is a white crystal that is easily sublimated and flammable. Therefore, it is necessary to use containers with good sealing properties, such as galvanized iron drums or ceramic cans. The container lid should be equipped with a sealing gasket to prevent naphthalene vapor from evaporating. The container should be free of damage and rust, with smooth inner walls and no burrs, to avoid static electricity generated by friction during storage of naphthalene crystals. For high-dose storage, a dedicated closed storage tank can be used, and the tank material should be resistant to slight corrosion by naphthalene. The interface should be sealed with threaded encrypted sealant, and the sealing performance should be checked regularly to prevent steam leakage.

　　储存环境的控制至关重要。存放地点需保持阴凉、通风，远离明火、热源（如暖气、火炉），环境温度不宜超过 30℃，因为精萘的熔点较低，高温易使其熔化并加速升华。同时，储存区域应避免阳光直射，可通过加装遮阳板或放置在阴凉仓库内实现。由于精萘蒸气与空气混合可能形成爆炸性混合物，储存场所需严禁吸烟，配备防爆型通风设备，通风口应设置在仓库底部，以利于密度较大的萘蒸气排出。

　　The control of storage environment is crucial. The storage location should be kept cool, ventilated, and away from open flames and heat sources (such as heaters and stoves). The ambient temperature should not exceed 30 ℃ because the melting point of refined naphthalene is low, and high temperatures can easily cause it to melt and accelerate sublimation. At the same time, the storage area should avoid direct sunlight, which can be achieved by installing sun visors or placing it in a cool warehouse. Due to the potential formation of explosive mixtures when naphthalene vapor mixes with air, smoking is strictly prohibited in storage areas. Explosion proof ventilation equipment should be equipped, and ventilation openings should be located at the bottom of the warehouse to facilitate the discharge of denser naphthalene vapor.

　　堆放方式需合理规范。桶装精萘应放置在平整的地面上，避免倾斜或堆叠过高，通常堆叠高度不超过两层，防止底层容器受压变形导致泄漏。容器之间需预留不少于 0.5 米的间距，便于通风和检查，同时避免相互碰撞产生火花。若使用托盘堆放，托盘需坚固耐用，防止坍塌，且托盘底部需垫放防潮板，避免地面潮气影响精萘质量。此外，储存区域内不得存放氧化剂、强酸、强碱等化学品，因为精萘与这些物质接触可能发生化学反应，引发危险。

　　The stacking method should be reasonable and standardized. Bottled refined naphthalene should be placed on a flat surface to avoid tilting or stacking too high. The stacking height should not exceed two layers to prevent leakage caused by deformation of the bottom container under pressure. A distance of no less than 0.5 meters should be reserved between containers for ventilation and inspection, while avoiding collisions and sparks. If using pallets for stacking, the pallets should be sturdy and durable to prevent collapse, and moisture-proof boards should be placed at the bottom of the pallets to avoid moisture on the ground affecting the quality of refined naphthalene. In addition, chemicals such as oxidants, strong acids, and strong bases must not be stored in the storage area, as contact between refined naphthalene and these substances may cause chemical reactions and pose a danger.

　　安全防护措施必不可少。储存场所需配备足够的消防器材，如干粉灭火器、灭火砂，严禁使用水基型灭火器，因为精萘不溶于水，用水灭火可能导致火势蔓延。工作人员进入储存区域时，需穿着防静电工作服和防滑鞋，避免产生静电，操作时轻拿轻放，防止容器碰撞。同时，储存区应设置明显的安全警示标识，注明 “易燃物品”“禁止烟火” 等字样，限制无关人员进入。

　　Security measures are essential. The storage area should be equipped with sufficient fire-fighting equipment, such as dry powder fire extinguishers and fire extinguishing sand. The use of water-based fire extinguishers is strictly prohibited because naphthalene is insoluble in water, and using water to extinguish the fire may lead to the spread of the fire. When entering the storage area, staff should wear anti-static work clothes and non slip shoes to avoid generating static electricity. When operating, handle with care to prevent container collisions. At the same time, clear safety warning signs should be set up in the storage area, indicating words such as "flammable materials" and "no smoking", to restrict unrelated personnel from entering.

　　日常检查与应急处理需常态化。定期检查储存容器的密封情况，观察是否有萘蒸气泄漏（可通过闻到煤焦油气味判断），若发现泄漏，需立即疏散周围人员，穿戴防护用具后进行处理，用沙土覆盖泄漏的晶体，收集后放入新的密封容器中。储存区域的地面应保持清洁，若有散落的精萘晶体，需及时清扫，避免其升华后浓度过高。此外，需建立储存台账，记录进出库数量、储存时间，定期轮换库存，优先使用储存时间较长的精萘，防止因长期储存导致品质变化。

　　Daily inspections and emergency response need to be normalized. Regularly check the sealing of storage containers and observe for any naphthalene vapor leaks (which can be determined by smelling coal tar). If a leak is found, immediately evacuate the surrounding personnel, wear protective equipment, and handle it. Cover the leaked crystals with sand and collect them and place them in a new sealed container. The ground of the storage area should be kept clean. If there are scattered naphthalene crystals, they should be cleaned up in a timely manner to avoid excessive concentration after sublimation. In addition, it is necessary to establish a storage ledger to record the quantity and storage time of incoming and outgoing inventory, regularly rotate inventory, prioritize the use of refined naphthalene with longer storage time, and prevent quality changes due to long-term storage.
