近日武漢肺炎疫情於香港持續擴散，市面上的清毒用品及口罩供不應求，好多市民都紛紛自製消毒酒精搓手液或口罩，以備不時之需。不過原來DIY酒精搓手液亦有不少注意事項，用錯塑膠容器裝消毒酒精搓手液或有機會釋出有毒物質！即睇邊款塑膠適合裝消毒酒精。
首先要在瓶底尋找三角形回收標誌，標誌內有不同號碼，代表不同種類的塑膠，塑膠普遍分為1至7號，而不同種類的塑膠有不同特性，並不是每種都適用於盛載消毒酒精。
1號塑膠為最普遍的塑膠，大部分水樽亦為1號塑膠所製造，按下圖睇塑膠特性。
2號塑膠是高密度聚乙烯(HDPE)，按下圖睇是否適合用作消毒酒精容器。
3號塑膠是聚氯乙烯PVC，按下圖睇聚氯乙烯危險性。
4號塑膠聚乙烯LDPE，按下圖睇聚乙烯是否適合用作消毒酒精容器。
5號塑膠聚丙烯。
6號塑膠為聚苯乙烯，其中發泡聚苯乙烯即是發泡膠。
7號塑膠是有不同種類的塑膠，賽先生不建議用作消毒酒精容器。
最後賽先生亦表示，如果家中沒有2號及5號塑膠，亦可以選擇相對較安全的1號及4號塑膠作後備方案。
