　　如遇精萘泄露可采取以下措施进行急救：

　　In case of naphthalene leakage, the following measures can be taken for first aid:

　　眼睛接触:提起眼睑，用流动清水或生理盐水冲洗。就医。

　　Eye contact: Lift the eyelids and rinse with flowing water or saline solution. Seek medical attention.

　　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。如呼吸停止，立即进行人工呼吸。就医。

　　Inhalation: Quickly leave the scene and move to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, administer oxygen. If breathing stops, immediately perform artificial respiration. Seek medical attention.

　　食入:饮足量温水，催吐，就医。

　　Ingestion: Drink sufficient warm water, induce vomiting, seek medical attention.

　　灭火方法:灭火剂:雾状水、二氧化碳、砂土。切勿将水流直接射至溶融物，以免引起严重的流淌火灾或引起剧烈的沸溅。

　　Fire extinguishing method: Fire extinguishing agent: misty water, carbon dioxide, sand. Do not directly spray water onto the molten material to avoid serious flowing fires or severe boiling splashes.
