After a serious violent and terrorist case at Kunming Railway Station in Yunnan, Malaysia Airlines Flight MH370 lost contact three days later, and catastrophic accidents occurred frequently. What caused these misfortunes? We, who are always side by side with time, can hardly predict what will happen in the next second. Can we only bear it silently? the answer is negative. Unpredictable, but seek prevention. Improve security and ensure safety.
A bottle of water "hides" through Malaysia Airlines security check and was brought on board
It has been three days since the Malaysia Airlines flight lost contact, and the media broke out. A passenger who took the MH370 one day in advance did not find a bottle of water at the airport. Ms. Jiao took her parents and children to travel abroad to transfer in Kuala Lumpur. Because the child's visa expired on the 8th, she changed her flight to MH370 on the 7th. She recalled that when she took the same flight on the 7th, she discovered potential safety hazards. "We threw two bottles of water at the security check, but when we boarded the plane, we found that there was another bottle in the bag. They didn't find it."
Security inspection is an important step to ensure the safe driving of planes, trains and other vehicles. During this process, all prohibited items will be prohibited from being carried, otherwise, the possibility of traffic accidents will be greatly increased. Water is one of the prohibited items. Being able to "hide" the security check and get on the plane reveals that the airport security check system is in urgent need of upgrading.
How to quickly pass the security check?
In order for you to pass the security check as soon as possible, please do the following:
1. Please do not bring prohibited items;
2. Please put the living knives in the luggage for consignment or not to carry.
3. Please do not bring liquid items such as beverages and restricted items such as matches and lighters; 4. Check baggage as much as possible during the registration process; 5. Prepare relevant boarding documents before accepting the security check; 6. In case of difficulties, please Promptly submit to security personnel for help;
How to carry electronic equipment with lithium batteries?
Improper transportation of lithium batteries may cause air transportation accidents. In order to ensure the safety of life and property of you and others, please follow the relevant regulations when carrying lithium battery powered devices and lithium batteries, and pay attention to the following:
1. Please put electrical equipment (such as digital camera, video camera, walkie-talkie, electric shaver, etc.) in your hand luggage, not in checked baggage.
2. Please install the battery on the electric equipment and protect it to avoid accidental startup of the electric equipment during carrying.
3. If you carry spare batteries, please protect the single spare batteries against short circuit, such as sticking the exposed electrodes with adhesive tape or packing each battery separately in a plastic bag or protective bag.
What are the precautions for carrying liquid items on domestic flights?
1. Only a small amount of cosmetics for travel (except shampoo and shower gel) can be carried. Each cosmetic is limited to one piece. The volume of its container must not exceed 100 ml, and it should be placed in a separate bag for inspection. Please be sure to confirm the following when you are ready to travel:
i. Whether the cosmetics you carry are used during the flight, if not, please put them in the checked baggage.
ii. Whether the volume of each cosmetics container is 100 ml of light rain. If not, please replace it with a container of less than 100 ml, or put it in checked baggage.
iii. Whether the cosmetics do not want to be damaged because they will be given to others. Because the cosmetics that you carry with you are subject to bottle opening inspection, if you do not want the packaging to be damaged, please put it in your checked baggage. iv. Alcoholic articles are not allowed to be carried with you. Please check them in your checked baggage.
2. If you are accompanied by an infant, please apply to your airline at the time of ticket purchase. The airline will provide liquid dairy products for free. The liquid dairy products you prepare yourself will not be allowed to be carried with you, you can put them in checked baggage or check them out, or handle them yourself before undergoing a security check.
3. Diabetics or other patients may carry the necessary liquid items, such as liquid medicines, liquid sugar-free foods, etc., but the number should be limited to the amount used during the air travel, and show the hospital or doctor's certificate.
4. If you come from overseas and need to transfer to a domestic flight at an airport in China, and carry tax-free liquid items purchased overseas, please put the liquid items in a transparent plastic bag with the bag intact and sealed, and you need to show Shopping voucher. If the sealed plastic bag containing liquid items is damaged or you cannot present your shopping voucher, you will not be allowed to carry the corresponding liquid items with you on domestic flights unless the volume and type of the liquid items you carry meet the relevant requirements for taking domestic flights.
