　　包装及储存：

　　Packaging and storage:

　　1. 采用内衬塑料袋，外编织袋包装，规格为25㎏。

　　1. It is packed with lined plastic bag and outer woven bag, with the specification of 25kg.

　　2. 与强氧化剂如铬酸酐、氯酸盐和高锰酸钾等接触，能发生强烈反应，引起燃烧或爆炸。

　　2. Contact with strong oxidants such as chromic anhydride, chlorate and potassium permanganate, strong reaction can occur and cause combustion or explosion.

　　3．储存于阴凉、通风库房内。远离火种、热源，防止阳光直射。保持容器密封。遇明火、高热可燃。燃烧时放出有毒的刺激性烟雾。

　　3. Store in cool and ventilated warehouse. Keep away from fire, heat source and direct sunlight. Keep the container sealed. Combustible in case of open fire and high heat. Toxic and irritating smoke is emitted when burning.

　　4. 运输时谨防遇锋利物，以防止破包受潮。运输过程中用雨布遮盖防止受潮。搬运时轻装轻卸，保持包装完整。

　　5. 粉体与空气可形成爆炸性混合物，当达到一定的浓度时，遇火星会发生爆炸。

　　5. Powder and air can form explosive mixture, when reaching a certain concentration, it will explode when meeting Mars.

　　安全防护：

　　Safety protection:

　　具有刺激作用，高浓度致溶血性贫血及肝、肾损害。

　　It can stimulate hemolytic anemia and damage liver and kidney.

　　1.急性中毒：吸入高浓度萘蒸汽或粉尘时，出现眼及呼吸道刺激、角膜浑浊、头痛、恶心、呕吐、食欲减退、腰痛、尿频、尿中出现蛋白及红白细胞，亦可发生视神经炎和视网膜炎。重者可发生中毒性脑病和肝损害。口服中毒主要引起溶血和肝、肾损坏，甚至发生急性肾衰竭和肝坏死。

　　1. Acute poisoning: when inhaling high concentration naphthalene vapor or dust, eye and respiratory tract irritation, corneal turbidity, headache, nausea, vomiting, anorexia, low back pain, frequent urination, protein and red and white cells in urine may occur, and optic neuritis and retinitis may also occur. Toxic encephalopathy and liver damage may occur in severe cases. Oral poisoning mainly causes hemolysis, liver and kidney damage, and even acute renal failure and liver necrosis.

　　2.慢性中毒：反复接触萘气，可引起头痛、乏力、恶心、呕吐和血液系统损害。可引起白内障、视神经炎和视网膜病变。皮肤接触可引起皮炎。

　　2. Chronic poisoning: repeated exposure to naphthalene can cause headache, fatigue, nausea, vomiting and blood system damage. It can cause cataract, optic neuritis and retinopathy. Skin contact can cause dermatitis.

　　3.接触到眼睛，提起眼睑，立即用大量清水或者生理盐水清洗，及时就医。

　　3. In case of contact with eyes, lift the eyelids, wash them immediately with plenty of water or normal saline, and seek medical advice in time.

　　4.接触到皮肤，脱去被污染的衣着，用肥皂水和清水彻底清洗皮肤。

　　4. When touching the skin, take off the contaminated clothes and wash the skin thoroughly with soapy water and water.

　　5.吸入。迅速脱离现场至空气新鲜处，保持呼吸道畅通。如呼吸困难，给输氧。如呼吸停止，立即进行人工呼吸，及时就医。

　　5. Inhalation. Leave the scene quickly to a place with fresh air and keep the respiratory tract unblocked. If breathing is difficult, give oxygen. If breathing stops, artificial respiration should be carried out immediately and medical treatment should be taken in time.

　　6.严禁食用。

　　6. Do not eat.

　　环境保护：

　　environmental protection:

　　严禁外流及随处倾倒，以免影响环境。

　　It is strictly forbidden to drain and dump everywhere, so as not to affect the environment.

　　隔离泄漏污染区，限制出入。切断火源。建议应急处理人员戴自给式呼吸器，穿一般工作服。不要直接接触泄漏物。小量泄漏：避免扬尘，使用无火花工具收集于干燥、洁净、有盖的容器中。运至空旷处引爆。或在保证安全情况下，就地焚烧。大量泄漏：用塑料布、帆布覆盖，减少飞散。使用无火花工具收集、回收或者运至废物处理场所处置。

　　Isolate the contaminated area and restrict access. Cut off the fire. It is suggested that emergency treatment personnel should wear self-contained breathing apparatus and general working clothes. Do not come into direct contact with the leakage. Small amount of leakage: avoid dust and collect in dry, clean and covered containers with non sparking tools. It's transported to an open area and detonated. Or in the case of ensuring safety, local incineration. Large amount of leakage: cover with plastic cloth and canvas to reduce scattering. Use non sparking tools to collect, recycle or transport to the waste disposal site for disposal.

　　消防指引：

　　Fire protection guidelines:

　　遇明火、高热可燃。燃烧时放出有毒的刺激性烟雾。与强氧化剂如铬酸酐、氯酸盐和高锰酸钾等接触，能发生强烈反应，引起爆炸或燃烧。粉体与空气形成爆炸性混合物，当达到一定浓度时，遇火星会发生爆炸。

　　Combustible in case of open fire and high heat. Toxic and irritating smoke is emitted when burning. Contact with strong oxidants such as chromic anhydride, chlorate and potassium permanganate can cause strong reaction and cause explosion or combustion. Powder and air form explosive mixture, when reaching a certain concentration, it will explode when it meets Mars.

　　灭火剂：二氧化碳、雾状水、砂土。切勿将水流直接射至熔融物，以免引起严重的流淌火灾或者引起剧烈的沸溅。

　　Fire extinguishing agent: carbon dioxide, fog water, sand. Do not spray water directly into the molten material, so as to avoid serious flowing fire or severe boiling splash.
