　　如遇精萘泄露可采取以下措施進行急救：

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

　　眼睛接觸:提起眼瞼，用流動清水或生理鹽水沖洗。就醫。

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

　　吸入:迅速脫離現場至空氣新鮮處。保持呼吸道通暢。如呼吸困難，給輸氧。如呼吸停止，立即進行人工呼吸。就醫。

　　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:飲足量溫水，催吐，就醫。

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

　　滅火方法:滅火劑:霧狀水、二氧化碳、砂土。切勿將水流直接射至溶融物，以免引起嚴重的流淌火災或引起劇烈的沸濺。

　　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.
