萘的危害和紧急处理方法

来源:http://www.jnjdbc.cn/ 日期:2022-01-06 发布人:admin
萘是简单的稠环芳烃,分子式为C10H8,是由2个苯环共用2个相邻碳原子稠合而成。无色,有毒,易升华并有特殊气味的片状晶体。从炼焦的副产品煤焦油和石油蒸馏中大量生产,主要用于合成邻苯二甲酸酐等。以往的卫生球就是用萘制成的,但由于萘的毒性,现在卫生球已经禁止使用萘作为成分。暴露的萘与溶血性贫血,导致肝脏和神经系统损伤、白内障和视网膜出血。萘的合理预期是人类的致癌物,并且可能与喉癌和大肠癌的风险增加有关。
Naphthalene is a simple polycyclic aromatic hydrocarbon with molecular formula of C10H8. It is fused by two benzene rings sharing two adjacent carbon atoms. Colorless, toxic, easy to sublimate and have a special smell of flake crystals. It is produced in large quantities from coal tar and petroleum distillation, which are by-products of coking, and is mainly used for the synthesis of phthalic anhydride. In the past, sanitary balls were made of naphthalene, but due to the toxicity of naphthalene, naphthalene has been banned as a component. Exposed naphthalene and hemolytic anemia lead to liver and nervous system damage, cataract and retinal hemorrhage. Naphthalene is reasonably expected to be a human carcinogen and may be associated with an increased risk of laryngeal and colorectal cancer.
健康危害
Health hazards
侵入途径:吸入、食入、经皮吸收。
Invasion route: inhalation, ingestion and 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 hazard: it has stimulating effect, and high concentration will 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、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
Acute poisoning: eye and respiratory tract irritation, corneal opacity, nausea, vomiting, anorexia, low back pain, frequent urination, protein and red blood in urine when inhaling high concentration naphthalene vapor or dust White blood cells. Can also occur
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。
Optic neuritis and retinitis. In severe cases, toxic encephalopathy and liver damage may occur. 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 fatigue, nausea, vomiting and blood system damage. It can cause cataract, optic neuritis and retinopathy. Skin contact can cause dermatitis.
应急处理处置方法:
Emergency handling methods:
一、泄漏应急处理
1、 Leakage emergency treatment
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
Isolate the leakage contaminated area and restrict access. Cut off the fire source. It is recommended that emergency treatment personnel wear self-contained breathing apparatus and general work clothes. Do not touch the leakage directly. Small leakage: avoid dust and use non sparking workers
具收集于干燥、洁净、有盖的容器中。运至空旷处引爆。或在保证没有危险的情况下,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
The utensils are collected in dry, clean and covered containers. Transport to the open area and detonate. Or incinerate on site when there is no danger. Massive leakage: cover with plastic cloth and canvas to reduce flying. Collect the oil with a non sparking tool
收或运至废物处理场所处置。
Received or transported to waste disposal site for disposal.
二、防护措施
2、 Protective measures
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: filter gas mask (half mask) should be worn in case of high concentration vapor contact; when it may be exposed to its dust, it is recommended to wear self-priming filter dust mask.
眼晴防护:戴化学防护眼镜。
Eye protection: wear chemical protective glasses.
身体防护:穿防毒物渗工作服。
Body protection: wear anti poison work clothes.
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。
Others: smoking, eating and drinking are prohibited at the work site. Shower and change clothes after work.
三、急救措施
3、 First aid measures
皮肤接触:脱去被污染的衣着,用把皂水和清水完全冲洗皮肤。
Skin contact: take off the contaminated clothes and completely wash the skin with soap and water.
眼睛接触:提起眼险,用流动清水或生理盐水冲洗。就医。
Eye contact: lift the eye danger and wash it with flowing water or normal saline. See a doctor.
吸入:迅速脱离现场至空气新鲜处。保持呼吸道通畅。如呼吸困难,给输氧。
Inhalation: quickly leave the site to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, give oxygen.
如呼吸停止,立即进行人工呼吸。就医。
If breathing stops, perform artificial respiration immediately. See a doctor.
食入:饮足量温水,催吐,就医。
Ingestion: drink enough warm water, induce vomiting and seek medical attention.
