暑期出行在即，旅客需要了解铁路和民航对携带物品的安检规定以避免行程延误。国铁南昌局鹰潭北站安检人员日前查获并没收了刀刃长度超过60毫米的刀具，以此为契机宣讲相关安检知识[1]。铁路禁止旅客随身携带刀刃长度超过60毫米的锐器类物品[1]，这是常见违禁品之一。
防晒喷雾、自热食品、充电宝等日常用品在携带时有明确限制。防晒喷雾单体容器容积不得超过150毫升，每种限带1件，所有喷雾累计不超过600毫升[1]。自热火锅和自热米饭禁止托运和随身携带[1]。驱蚊液、消杀用品等每种限带一瓶，单瓶容器容积不能超过100毫升[1]。铁路充电宝单块额定能量不超过100瓦时，仅能随身携带不能托运[1]。此外干冰禁止乘火车[1]。
民航对这些物品的规定略有差异。护肤品需盛放在单体容器容积不超过100毫升的容器内[1]。充电宝如具有3C标识且额定能量不超过100瓦时可直接携带，额定能量在100至160瓦时需获得航空公司批准，每位旅客最多携带两块[1]。民航点火器具一律禁止携带[1]，刀刃超过6厘米的剪刀不能随身携带只能托运[1]。
As the summer travel season approaches, transportation security authorities are reminding passengers of strict regulations governing prohibited and restricted items. China Railways Nanchang Bureau recently confiscated an oversized knife at Yingtan North Station, highlighting the importance of understanding these rules before traveling [1].
For rail passengers, regulations on common items are particularly stringent. Knives with blades longer than 60 millimeters are classified as prohibited sharp objects and cannot be carried aboard [1]. Sunscreen sprays are restricted to containers no larger than 150 milliliters per unit, with a maximum of one per type and a total limit of 600 milliliters across all sprays [1]. Self-heating hotpots and self-heating rice meals are banned from both checked and carry-on luggage [1]. Insect repellents and disinfectants are limited to one bottle per type, with individual containers not exceeding 100 milliliters [1]. Power banks are permitted only in carry-on baggage with a rated energy capacity not exceeding 100 watt-hours and cannot be checked [1]. Dry ice is completely prohibited on trains [1].
Civil aviation authorities maintain similarly strict protocols for passengers. Skincare products must be contained in individual bottles with a capacity not exceeding 100 milliliters [1]. Power banks with 3C certification and rated energy not exceeding 100 watt-hours can be carried directly; those rated between 100 and 160 watt-hours require airline approval, with a maximum of two units per passenger [1]. All lighters and ignition devices are banned from aircraft [1]. Scissors with blades longer than 6 centimeters cannot be brought through security checkpoints and may only be checked in luggage [1].
