Airports' Hunt For Lithium Batteries: Strategies And Challenges

Lithium-ion batteries are commonly found in everyday products, such as smartphones, laptops, tablets, and electric vehicles. Given their widespread use, it is not surprising that lithium-ion batteries often make their way into airports and aircraft. However, these batteries pose safety risks, as they are capable of overheating and undergoing thermal runaway, which can lead to fires. As a result, airports have implemented various procedures to identify and manage the safe transportation of lithium-ion batteries. This includes regulations on the quantity, size, and placement of batteries within carry-on or checked baggage, as well as safety protocols for flight crews to handle potential battery-related incidents. Understanding how airports address the challenges associated with lithium-ion batteries is crucial for ensuring the safety of passengers and mitigating potential hazards.

Lithium-ion batteries are used in everyday products like smartphones, laptops, and tablets

In addition to consumer electronics, lithium-ion batteries are used in renewable energy, transportation, and medical fields. They power electric vehicles, drones, and marine propulsion systems. In the medical field, they are used in portable ultrasound machines, ECG monitors, motorized wheelchairs, and implantable devices like pacemakers.

Despite their widespread use, lithium-ion batteries have been linked to a growing number of fire incidents. All lithium-ion batteries use flammable materials, and if not used correctly or if damaged, they can cause fires or even explosions. This poses a safety risk, especially in airplanes, where lithium-ion batteries are commonly found in passengers' electronic devices.

To ensure safety, airlines have implemented measures to manage the risks associated with lithium-ion batteries. Passengers are often asked about these batteries during check-in or boarding. There are quantity and size limits for lithium-ion batteries on airplanes, and passengers may be required to carry them in carry-on baggage only. Additionally, flight attendants are trained to recognize and respond to lithium-ion battery fires, using fire containment bags, buckets, and pouring water or soda to extinguish them.

Lithium batteries are capable of overheating and catching fire if damaged

Lithium-ion batteries are commonly used in everyday products such as smartphones, laptops, tablets, and electric vehicles. They are popular because they can store more energy in a smaller and lighter package. However, lithium batteries are susceptible to overheating and catching fire if damaged, which poses a safety risk. This process is known as "thermal runaway", which can occur without warning due to various factors, including physical damage, manufacturing defects, overcharging, or improper packing. In extreme cases, thermal runaway can lead to the battery catching fire or even exploding.

To prevent lithium-ion batteries from overheating and catching fire, several precautions must be taken. Firstly, it is essential to protect the battery terminals from short circuits by covering them with tape, using a battery case, or placing them in a plastic bag. Additionally, passengers are usually limited to carrying only two spare larger lithium-ion batteries or lithium metal batteries, and these must be stored in carry-on baggage only. This is because lithium batteries are required to undergo safety testing, and in the event of a fire, the flight crew is trained to respond and contain it.

The dangers of lithium-ion battery fires lie not only in the flames but also in the toxic fumes they emit. These fires release dangerous gases such as carbon monoxide, hydrogen fluoride, and hydrogen chloride, which can be hazardous to health when inhaled. Therefore, it is crucial to notify the flight crew immediately if a lithium battery or device is exhibiting any signs of overheating, expanding, smoking, or burning.

While lithium-ion battery fires are rare, they can have severe consequences. To minimize the risk of fires, it is essential to follow safety precautions and properly handle and store lithium-ion batteries. By taking these necessary precautions, we can ensure the safe use of lithium-ion batteries in our everyday lives.

Flight attendants are trained to deal with lithium battery fires

Flight attendants are often the first line of defence against lithium battery fires, so it is imperative that they are properly trained to deal with them. A lithium battery fire can occur at any time, and these batteries can overheat, emit smoke, burst into flames, or even explode, causing a serious risk to the aircraft and its crew and passengers.

Flight attendants are trained to fight lithium battery fires by cooling the batteries inside the device. This can be done by submerging the device in liquid, such as in a sink or metal trash can. This is the only way to halt thermal runaway, and it requires a significant amount of liquid. Flight attendants must get within arm's length of the unstable device, which can be unsafe, so it is recommended that they are provided with protective equipment, such as fireproof gloves and a face shield.

In addition to this training, flight attendants are also instructed on the use of specialised containment bags, which can be used to store devices containing lithium batteries. These bags can help to contain a fire and prevent it from spreading. It is important that flight attendants are aware of the location of these bags and any other relevant equipment, and that they are trained to use them effectively.

Public awareness and education about the dangers of lithium-ion batteries are also crucial. Passengers should be instructed to monitor their devices during a flight and to notify the crew immediately if a device becomes warm, discoloured, or bulged. Additionally, passengers should follow directions from the flight crew regarding the use of electronic devices, such as turning off laptops and unplugging chargers during take-off and landing.

Lithium batteries must be stored in carry-on baggage and protected from damage

Lithium batteries are commonly used in everyday items such as smartphones, laptops, tablets, cameras, flashlights, and even electric vehicles. Given their prevalence, it is inevitable that airline passengers will bring such devices on board. However, lithium-ion batteries pose certain risks, particularly when damaged, short-circuited, overheated, or exposed to water. In such cases, they can undergo "thermal runaway", which may result in the battery overheating, expanding, smoking, or even catching fire.

Due to these risks, lithium batteries must be stored in carry-on baggage to ensure they remain within the passenger's control and can be promptly addressed if any issues arise. This is a safety measure as flight crews are trained to recognize and respond to lithium battery fires in the cabin. Passengers should immediately notify the flight crew if their lithium battery or device exhibits any abnormal behavior, such as overheating, expanding, smoking, or burning.

To prevent issues with lithium batteries, it is essential to protect the batteries from damage and accidental activation during the flight. This includes ensuring that the battery terminals are protected and do not come into contact with other metal objects to prevent short circuits. Passengers can achieve this by leaving the batteries in their original packaging, covering the terminals with tape, using a battery case or sleeve, or placing them in separate plastic bags or protective pouches. Additionally, spare batteries, including power banks, should not be recharged while on board the aircraft, and power banks should not provide power to any devices during the flight.

It is worth noting that some devices, such as small lithium battery-powered personal transportation devices (hoverboards, self-balancing devices, or gravity boards), pose a higher risk and may be restricted by certain airlines. Therefore, it is advisable to leave such items at home when traveling by air. By following these guidelines and storing lithium batteries in carry-on baggage, passengers can help ensure their safety and the safety of those around them.

Lithium batteries must be for personal use, not for sale or distribution

Lithium batteries are commonly used in everyday items such as smartphones, laptops, tablets, and cameras. Due to their high energy density, they can pose safety risks, particularly during air travel. As such, airports have specific guidelines for passengers travelling with lithium batteries.

Passengers are allowed to carry lithium batteries for personal use, but there are quantity and size limits. For most batteries, there are no quantity restrictions, but batteries must be intended for personal use only. Batteries intended for further sale or distribution are prohibited. Each passenger is limited to two spare larger lithium-ion batteries (101-160 Wh) or lithium metal batteries (2-8 grams). These larger batteries are typically used in after-market extended-life laptop computer batteries and professional audio/visual equipment.

To ensure safety, lithium batteries must be protected from damage and short circuits. Battery terminals should be covered with tape or placed in a separate plastic bag to prevent contact with other metal objects. Additionally, passengers should carry spare batteries in their carry-on baggage only. When a carry-on bag is checked at the gate or planeside, spare batteries and power banks must be removed and kept with the passenger in the aircraft cabin.

It is important to note that damaged, recalled, or defective batteries that may create sparks or generate dangerous heat must not be carried aboard an aircraft. If a battery needs to be transported, it must be removed or made safe according to the manufacturer's guidelines. Passengers should also be aware of any signs of overheating, expansion, smoking, or burning during the flight and notify the flight crew immediately. Flight crews are trained to handle lithium battery fires and take necessary safety precautions.
