Can 150ml sunscreen spray pass the security check of the train?

150ml sunscreen spray cannot pass the security check of the train. Passengers can carry no more than 20 ml of nail polish, polish remover, and hair dye; no more than 120 ml of self-spray pressure containers such as cold perm, mousse, hair spray, insecticides, and air fresheners can be carried; and only 2 small boxes of safety matches can be carried. ; Ordinary lighters can only carry 2.

"The smoke detectors of high-speed rail are all set with a 'dimmer coefficient' (ranging between 0.1-0.19). When the data detected by the detector reaches the set alarm value, an alarm will be triggered. The light reduction coefficient set on the train is 0.16, which is within a reasonable range.”

Because the train toilet space is closed and narrow, a large number of “smoke particles” are generated when spraying sunscreen spray, and the smoke detector detects the smoke. If the concentration "exceeds the standard", it will trigger the fire alarm system and force the high-speed train to stop, which is very dangerous.

In terms of publicity, the ban on smoking on high-speed railways has been heavily promoted, basically to the extent that it has been widely advertised and known to women and children. However, the ban on carrying and using perfume has not been so vigorously promoted. This is related to the concentration and dosage of the perfume. A low concentration or a small amount of use will not be enough to stop the train.

One day, on the high-speed train from Zhengzhou East to Anyang East, a female passenger used sunscreen spray in the train bathroom At that time, a large number of "smoke particles" were generated. After the smoke detector alarm system was triggered, the train was delayed for 3 minutes and subsequent trains were also affected and delayed one after another.

News about trains being forced to stop is not uncommon, but it is rare for passengers to be forced to stop because they use sunscreen spray. Therefore, in the face of the crew members who rushed to deal with the situation, the female passenger involved While apologizing, he was also surprised at the serious consequences of his inadvertent behavior.

In fact, although forcing the train to stop is of great importance, the female passengers cannot be entirely blamed for their ignorance. Many netizens also expressed ignorance about this, and some even questioned whether the high-speed train's smoke detector was too sensitive. .

The train was delayed because a female passenger used sunscreen spray. This incident may seem a bit dramatic at first glance, but the railway system’s lack of common sense on safe transportation and passenger behavior regulations has led to a weak safety awareness among the public. Get attention.

The "Railway Passenger Transport Regulations" clearly stipulates prohibited and limited items, but there are no clear regulations for daily necessities such as sunscreen spray and toilet water. Therefore, the implementation standards of security inspections at railway stations in various places are Not the same.

Some people believe that "most sprays contain volatile organic solvents such as ethanol and alkanes, which are easily ignited" and restrict passengers from taking them on the train, while others only "recommend not to carry them with you" , requiring “bringing small bottles”. Passengers also have no way of knowing the more detailed safety regulations such as the prohibition of using sunscreen spray in enclosed train spaces.

As for whether the female passenger involved who forced the train to stop could bring the spray on the train, or whether it exceeded the limit, the news did not mention it.

In daily life, when people take public transportation such as trains, many people do not know whether the items they carry comply with safety regulations. They often need to search online, but they can obtain information based on this The information is not authoritative either.

Many people are not willing to spend more time and cost to proactively inquire. Often they only find out that the items exceed the regulations when they go to the train station for security inspection, and they can only hand it over to security inspection for processing. This has not only caused economic losses to passengers, but also increased the workload of the railway system. If the security check is temporarily neglected, it will even cause a small probability event such as using sunscreen spray to force the train to stop.

Nothing is trivial in the operation of high-speed rail. The railway system might as well make a more detailed list of items, which can be used and which cannot be used, and inform passengers on the train by broadcasting or posting slogans to prevent passengers from violating regulations and making mistakes. Fog.

At the same time, we should strengthen the publicity of items that are prohibited from being carried on the train, and move the "security check" from the front of the train station to the dissemination of daily life, reducing the cost for the public to obtain such information. The railway system ensures that safety regulations are as detailed as possible to ensure the safe travel of people to the greatest extent.
