safety worries lead us airline to ban battery shipments - lithium ion rechargeable battery
United Airlines has become the second largest airline in the United States, announcing that it will no longer ship a large amount of lithiumion batteries.
Delta stopped mass shipping of batteries in February.
Aviation officials believe lithium
Two Boeing 747 freighters caught fire with ion batteries and all four crew members were killed.
A Federal Aviation Administration test found that overheating of the battery could cause a major fire.
During the test, the FAA filled a container with 5,000 lithium.
Ion batteries and cartridge heaters have been added to simulate overheating of a single battery.
The heat of the cartridge causes a chain reaction in other batteries, and the temperature reaches about 600C.
A subsequent explosion opened the container door and caught fire.
A few months later, the second test produced similar results, despite the increase in fire
Inhibitor.
"When transporting dangerous goods, our primary problem is the safety of the customer, the customer's goods and the environment," United Airlines said in a statement . ".
Experts believe that in recent years, the fire of several cargo machines is caused by batteries.
In 2010, a Boeing 747 freighter operated by UPS Airlines
The plane caught fire and crashed in an uninhabited area of Dubai.
Two crew members were killed.
In the subsequent investigation, the FAA highlighted a large number of lithium-
There are ion batteries on board.
On 2011, one carrying 880lb (400kg)
Two crew members crashed in the South Korean Strait.
The cause of the fire has never been determined, but the International Civil Aviation Organization does recommend new safety standards for the transportation of such batteries.
On 2006, a UPS cargo plane landed urgently after a fire at Philadelphia International Airport.
In this case, all the crew escaped unscathed.
The cause of the fire has never been determined, but the proposals of the National Transportation Safety Board include proposals on lithium transportion batteries.
It is reported that Malaysia Airlines Flight 370 also carries 440 of lithium-
Its cargo contains ion batteries, adding another theory to the mystery of last year's disappearance.
The growing focus on battery safety will put pressure on other airlines to follow suit and also put pressure on the tech industry to come up with safer modes of transport. Lithium-
Ion batteries power mobile phones, laptops and other digital devices. An estimated 4.
8 billion lithium
Ion batteries were manufactured in 2013 and production is expected to reach 8 billion by 2025.
According to the safety standards set by the United Nations International Civil Aviation Organization, the shipment of rechargeable batteries on passenger planes should be limited to no more than a few in a box.
But a loophole allows many small boxes to be packed into a batch of cargo, which means that thousands of batteries may be packed into pallets and loaded into the cargo hold of the passenger plane.
Passenger Airlines did not have a cargo fire caused by batteries.
American Airlines stop accepting certain types of lithium.
Ion battery shipments in February
It continues to accept small packaged batteries grouped together or packed in a cargo container.
However, this caused a safety problem due to the large number of batteries in a container.
The FAA test also showed that lithium
The metal battery is not a rechargeable and power unit like a camera and a calculator, it fires much faster than other versions of the battery.
The United Nations banned the delivery of these batteries on passenger planes last year, which came into effect on January.
About 10% of 2.
5 billion lithium
Metal Batteries made every year are flown by air. Lithium-
The frequency of air transport for ion batteries is much higher.
All three American Airlines will continue to accept shipments when batteries are installed inside or equipped with equipment such as laptops or power tools.
