精萘有哪些毒性?

来源:http://www.jnjdbc.cn/ 日期:2020-07-13 发布人:guanli
  精萘的水溶性较小,而且不易被吸收,故其毒性不太强。吸入浓的萘蒸气或萘粉末时,能促使人呕吐,不适,头痛。特别是损害眼角膜,引起小水泡及点状浑浊,还能使皮肤发炎,有时还能引起肺的病理改变,还可损害肾脏,引起血尿,但没有致癌性。工作场所萘的大容许浓度为10×10-6。生产设备及容器应密闭,防止蒸气粉末外逸,操作现场强制通风。若发生中毒现象,要立即移至新鲜空气处,多饮热水,使之呕吐,进行人工呼吸,严重者送医院治疗。

  The water solubility of refined naphthalene is small, and it is not easy to be absorbed, so its toxicity is not very strong. Inhalation of dense naphthalene vapor or naphthalene powder, can promote vomiting, discomfort, headache. In particular, damage to the cornea, causing small blisters and spotty turbidity, but also can make skin inflammation, sometimes can cause lung pathological changes, can also damage the kidney, causing hematuria, but not carcinogenic. The maximum allowable concentration of naphthalene in the workplace is 10 × 10-6. The production equipment and containers should be sealed to prevent steam powder from escaping, and the operation site should be forced to ventilate. If poisoning occurs, immediately move to fresh air, drink more hot water, make it vomit, and carry out artificial respiration. If serious, send to hospital for treatment.
  液体精萘用槽车运输、固体精萘用牛皮纸袋装,净重25kg。运输贮存过程中,防止火种。
  The liquid refined naphthalene is transported by tank car, and the solid refined naphthalene is packed in kraft paper bag with a net weight of 25kg. Prevent fire during transportation and storage.
