　　4. 運(yùn)輸時(shí)謹(jǐn)防遇鋒利物，以防止破包受潮。運(yùn)輸過(guò)程中用雨布遮蓋防止受潮。搬運(yùn)時(shí)輕裝輕卸，保持包裝完整。

　　4. Be careful to avoid sharp objects during transportation, so as to prevent damage and damp. Cover with rain cloth to prevent damp during transportation. Handle with care, keep package intact.

　　5. 粉體與空氣可形成爆炸性混合物，當(dāng)達(dá)到一定的濃度時(shí)，遇火星會(huì)發(fā)生爆炸。

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

　　安全防護(hù)：

　　Safety protection:

　　具有刺激作用，高濃度致溶血性貧血及肝、腎損害。

　　It can stimulate hemolytic anemia and damage liver and kidney.

　　1.急性中毒：吸入高濃度萘蒸汽或粉塵時(shí)，出現(xiàn)眼及呼吸道刺激、角膜渾濁、頭痛、惡心、嘔吐、食欲減退、腰痛、尿頻、尿中出現(xiàn)蛋白及紅白細(xì)胞，亦可發(fā)生視神經(jīng)炎和視網(wǎng)膜炎。重者可發(fā)生中毒性腦病和肝損害。口服中毒主要引起溶血和肝、腎損壞，甚至發(fā)生急性腎衰竭和肝壞死。

　　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：反復(fù)接觸萘氣，可引起頭痛、乏力、惡心、嘔吐和血液系統(tǒng)損害?？梢鸢變?nèi)障、視神經(jīng)炎和視網(wǎng)膜病變。皮膚接觸可引起皮炎。

　　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.接觸到眼睛，提起眼瞼，立即用大量清水或者生理鹽水清洗，及時(shí)就醫(yī)。

　　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.接觸到皮膚，脫去被污染的衣著，用肥皂水和清水徹底清洗皮膚。

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

　　5.吸入。迅速脫離現(xiàn)場(chǎng)至空氣新鮮處，保持呼吸道暢通。如呼吸困難，給輸氧。如呼吸停止，立即進(jìn)行人工呼吸，及時(shí)就醫(yī)。

　　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.嚴(yán)禁食用。

　　6. Do not eat.

　　環(huán)境保護(hù)：

　　environmental protection:

　　嚴(yán)禁外流及隨處傾倒，以免影響環(huán)境。

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

　　隔離泄漏污染區(qū)，限制出入。切斷火源。建議應(yīng)急處理人員戴自給式呼吸器，穿一般工作服。不要直接接觸泄漏物。小量泄漏：避免揚(yáng)塵，使用無(wú)火花工具收集于干燥、潔凈、有蓋的容器中。運(yùn)至空曠處引爆。或在保證安全情況下，就地焚燒。大量泄漏：用塑料布、帆布覆蓋，減少飛散。使用無(wú)火花工具收集、回收或者運(yùn)至廢物處理場(chǎng)所處置。

　　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、高熱可燃。燃燒時(shí)放出有毒的刺激性煙霧。與強(qiáng)氧化劑如鉻酸酐、氯酸鹽和高錳酸鉀等接觸，能發(fā)生強(qiáng)烈反應(yīng)，引起爆炸或燃燒。粉體與空氣形成爆炸性混合物，當(dāng)達(dá)到一定濃度時(shí)，遇火星會(huì)發(fā)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.

　　滅火劑：二氧化碳、霧狀水、砂土。切勿將水流直接射至熔融物，以免引起嚴(yán)重的流淌火災(zāi)或者引起劇烈的沸濺。

　　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.
