精萘可用染料，医药等领域，如生产2-萘酚、1-萘酚和甲萘胺等，也是生产樟脑的主要原料。

Refined naphthalene can be used in fields such as dyes and pharmaceuticals, such as producing 2-naphthol, 1-naphthol, and methylnaphthylamine, and is also the main raw material for producing camphor.

对环境的影响

The impact on the environment is also significant

健康危害

Health hazards

侵入途径：吸入、食入、经皮吸收。

Invasion routes: inhalation, ingestion, percutaneous absorption.

健康危害：具有刺激作用，高浓度致溶血性贫血及肝、肾损害。

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

急性中毒：吸入高浓度萘蒸气或粉尘时，出现眼及呼吸道刺激、角膜混浊、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、肾损害，甚至发生急性肾功能衰竭和肝坏死。

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：反复接触萘蒸气，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。

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.

应急处理

Emergency response

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，穿一般作业工作服。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运至废物处理场所处置。

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.

防护措施

Protective measures also include

呼吸系统防护：高浓度蒸气接触可应该佩戴过滤式防毒面具（半面罩）；可能接触其粉尘时，建议佩戴自吸过滤式防尘口罩。

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.

眼睛防护：戴化学安全防护眼镜。

Eye protection: Wear chemical safety goggles.

身体防护：穿防毒物渗透工作服。

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

手防护：戴防化学品手套。

Hand protection: Wear chemical resistant gloves.

其它：工作现场禁止吸烟、进食和饮水。工作毕，淋浴更衣。
