3-Cyanoumbelliferone實驗注意事項：
1.實驗前需戴好防護眼鏡，穿戴防護服和口罩，佩戴手套，避免與皮膚接觸。
2.實驗過程中如遇到有毒或者刺激性物質及有害物質產生，必要時實驗操作需要手套箱內完成以免對實驗人員造成傷害
3.實驗后產生的廢棄物需分類存儲，并交于專業(yè)生物廢氣物處理公司處理，以免造成環(huán)境污染。
Experimental considerations:
1. Wear protective glasses, protective clothing and masks, gloves, and avoid contact with the skin during the experiment.
2. The waste generated after the experiment needs to be stored separately, and handed over to a professional biological waste gas treatment company to avoid environmental pollution.
