the problem with stowing lithium-ion batteries on planes

Ban the use of most electronic devices in some American cabinsS. -
Binding flights may be designed to thwart terrorist attacks, but it also raises questions about the safest place to store lithium devices
Ion batteries on the plane
The Department of Homeland Security announced Tuesday that passenger cabins that fly to the United States will not be allowed to carry laptops and other large electronic devices. S.
10 airports from the Middle East and North Africa.
The move is in response to intelligence reports that terrorists are looking for new ways to place explosives in electronic equipment on the plane.
Passengers on these flights will now be required to pack the equipment in their checked baggage.
But because of lithium
Ion battery in laptopthough rarely—
The new rule raises the question: is it dangerous to put hundreds of laptops in suitcases on a plane?
Over the past few years, aviation safety experts have conducted extensive research on this issue.
There is a new view that yes, it would be safer if the laptop and similar equipment were placed in the passenger compartment rather than in the cargo compartment. Why?
First, if a laptop is on fire in the cabin, it will be noticed immediately and steps can be taken to put it out.
Although there is a fire safety system on the plane, they are not good-
Equipped to handle fire types of lithium-
Ion batteries are produced.
\"There\'s a balance here,\" said John Cox, a former pilot and CEO of the airline\'s security operating system.
\"When we put lithium-
Ion batteries in the cargo hold, if the crew does catch fire, they are no longer in areas that the crew can handle.
Fire Fighting System using only [
Common fire extinguishing agent. ]
Halon has not been shown to be effective for lithiumion fires. ”If a battery-
The power unit is on fire in the cargo hold, and the Halon in the airborne suppression system may extinguish the flame, but the battery will continue to heat up and may cause other fires.
\"If you have a cargo hold with a lot of lithium batteries, it can spread to more devices once you start the heating process,\" Cox said . \".
\"You have to re-ignite.
The Federal Aviation Administration is \"in a very, very difficult situation,\" Cox added . \"
\"He acknowledges the challenges faced in weighing the threat of terrorism and internal threats
Flying Battery Fire
\"I would like to see a risk analysis, but, at this point, I think we have reduced some of the risks and introduced some others.
At a news conference on Monday night, senior government officials acknowledged
The ion batteries from the cabin to the cargo compartment of the aircraft do cause some danger. “Lithium-
Ion batteries are a known safety risk, \"said Karen Walker, editor of the aviation industry trade publication Air Transport World.
\"If they are on fire, it is very hot.
The fire and the plane didn\'t mix very well.
According to James Dixon, chief science officer of the consumer report, when the battery fails, it is usually because the membrane of the separated charge in the battery is destroyed, it creates a short circuit, and the sudden release of energy.
This intense energy burst caused the battery to reach a temperature of close to 1,000 degrees Fahrenheit, which may disrupt the stability of the nearby battery, resulting in a situation called heat out of control. Lithium-
Ion batteries have become news in recent months, and spectacular videos of various devices have appeared on YouTube --
From hovercraft to headphones-
Burn up.
Last fall, the FAA banned Samsung Galaxy Note7 smartphones from entering the U. S. market. S.
After the flight was recalled due to reports of fire and explosions.
But given the millions of devices powered by rechargeable lithium, it\'s important to keep the danger in the long run
Ion batteries are put into use every day. Frequency (of fires)
This is fairly small compared to the number of batteries in use, but it is still a potential hazard, \"said Dickson, an expert in battery science.
He added that non-rechargeable batteries, such as AA and AAA batteries that you might find on the remote control, do not pose the same threat to consumers.
Last year, the FAA warned that lithium for transporting pallets
Lithium ion or non-rechargeable lithium-
If a battery is on fire, the metal battery in the cargo compartment of the aircraft may result in a \"catastrophic explosion \".
While there is no complete ban, the agency warns against packaging large quantities of batteries together --
Because the heat is out of control.
And warned that the battery should be separated from other hazardous materials.
International Civil Aviation Organization (ICAO)
Associated with the United Nations, which banned the transportation of lithium last year-
Ion batteries are used as cargo on passenger planes due to safety concerns.
As with the FAA restrictions, the move involves only commercial goods, not electronic equipment carried by passengers or hidden under the aircraft.
Although passengers on domestic flights are currently allowed to pack equipment containing lithiumion or lithium-
Metal Battery with you
When baggage is on or checked in, the FAA requires a spare battery-
Equipment not installed in the device-
Only carry-
On the bag, because the battery with an unprotected electrode has the potential to touch loose metal objects and short circuit, it is ignited.
The FAA postponed comments on Homeland Security on Tuesday.
The International Civil Aviation Organization issued a statement acknowledging the need to constantly respond to emerging threats, noting the importance of \"finding an effective balance between safety and security approaches.
\"According to government officials, the Department of Homeland Security is working with the FAA and airlines to determine the best way to implement new travel restrictions.
The State Council has been in contact with eight airport countries affected by these measures.
Smartphones and medical equipment belonging to passengers and electronic equipment carried by aircraft crew members are not subject to the ban.
Officials said there was no end date for the restrictions.
They continue to assess intelligence and open their doors to other airports for new security measures.
Currently, this initiative affects flights from specific airports in Jordan, Egypt, Turkey, Saudi Arabia, Kuwait, Morocco, Qatar and the UAE.
Nine foreign airlines and about 50 flights fly to the United States every day. S.
Will be affected. No U. S. -
Because no airline currently offers uninterrupted service from the affected airport to the United States. S.
Britain also announced a similar ban on Tuesday. The U. S.
Changes took effect at three in the morning. m.
On Tuesday Eastern time, airlines have 96 hours to comply.
Those who don\'t see their permission to land in the United StatesS.
Officials said it was revoked.
