健康危害

Health hazards

侵入途徑：吸入、食入、經(jīng)皮吸收。

Invasion routes: inhalation, ingestion, percutaneous absorption.

健康危害：具有刺激作用，高濃度致溶血性貧血及肝、腎損害。

Health hazards: It has a stimulating effect and high concentrations can cause hemolytic anemia and liver and kidney damage.

急性中毒：吸入高濃度萘蒸氣或粉塵時(shí)，出現(xiàn)眼及呼吸道刺激、角膜混濁、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?？诜卸局饕鹑苎透?、腎損害，甚至發(fā)生急性腎功能衰竭和肝壞死。

Acute poisoning: When inhaling high concentrations of naphthalene vapor or dust, eye and respiratory irritation, corneal opacity, headache, nausea, vomiting, decreased appetite, lower back pain, frequent urination, and the appearance of protein and red and white blood cells in urine may occur. Optic neuritis and retinitis can also occur. Severe cases can lead to toxic encephalopathy and liver damage. Oral poisoning mainly causes hemolysis, liver and kidney damage, and even acute renal failure and liver necrosis.

慢性中毒：反復(fù)接觸萘蒸氣，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。

Chronic poisoning: Repeated exposure to naphthalene vapor can cause headaches, fatigue, nausea, vomiting, and damage to the blood system. Can cause cataracts, optic neuritis, and retinopathy. Skin contact can cause dermatitis.

應(yīng)急處理

Emergency response

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，穿一般作業(yè)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?；蛟诒ＷC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運(yùn)至廢物處理場(chǎng)所處置。

Isolate the contaminated area and restrict entry and exit. Cut off the fire source. It is recommended that emergency response personnel wear self-contained breathing apparatus and general work clothes. Do not come into direct contact with leaks. Small leakage: Avoid dust and collect in a dry, clean, and covered container using spark free tools. Transport to an open area for detonation. Or, while ensuring safety, burn on site. Large leakage: Cover with plastic or canvas to reduce scattering. Use spark free tools to collect and recycle or transport to waste disposal sites for disposal.

防護(hù)措施

Protective measures also include

呼吸系統(tǒng)防護(hù)：高濃度蒸氣接觸可應(yīng)該佩戴過(guò)濾式防毒面具（半面罩）；可能接觸其粉塵時(shí)，建議佩戴自吸過(guò)濾式防塵口罩。

Respiratory protection: When exposed to high concentrations of steam, a filtered gas mask (half face mask) should be worn; When in contact with its dust, it is recommended to wear a self-priming filter dust mask.

眼睛防護(hù)：戴化學(xué)安全防護(hù)眼鏡。

Eye protection: Wear chemical safety goggles.

身體防護(hù)：穿防毒物滲透工作服。

Body protection: Wear work clothes that prevent the penetration of toxins.

手防護(hù)：戴防化學(xué)品手套。

Hand protection: Wear chemical resistant gloves.

其它：工作現(xiàn)場(chǎng)禁止吸煙、進(jìn)食和飲水。工作畢，淋浴更衣。

Other: Smoking, eating, and drinking are prohibited at the workplace. After work, take a shower and change clothes.
