WORLDWIDE – For well over a decade we have written of the dangers of the carriage of lithium batteries, particularly as air cargo. Now comes a useful reminder to freight forwarders and the like of the steps necessary to ensure the safe transport of something which now permeates much of the technology we rely on.
Nothing illustrates the problems better than the Boeing Dreamliner situation, a plane entirely dependent on lithium technology, in which the entire fleet had to be grounded when the batteries started smoking on some aircraft. The, some might say all too simple solution? Put them in a metal box from where no fire could spread.
So now Suffolk based transport outfit Greencarrier has offered some advice to ensure the horrific cargo plane crashes of the past might be avoided in the future. Firstly it is damaged batteries which are the principal cause of problems. Shippers need to examine all cells to avoid them short-circuiting, causing fire and even explosion.
Used in laptops, smartphones, electric vehicles, and medical devices, they connect our world and help save lives but are still classified as dangerous goods. This has led to thousands of lithium battery shipments being stopped daily at airports around the world. Sometimes, shippers are not fully aware of the properties of lithium batteries and their classification. However most of the time, the complexity of the regulations is the obstacle.
It is the responsibility of the shipper to ensure lithium batteries are packed and shipped safely. It is essential to follow regulations, guidelines, and appropriate precautions when preparing the batteries for transportation. Failure to attend to these can lead to at best a suspension of shipment, perhaps a ban from exporting and, at worst, a fatal accident.
To mitigate these risks, here are Greencarrier’s four tips on how to ship your lithium batteries safely:
You may also need to have other documents and certificates in place prior to shipping. For example, your shipping company may ask you to sign a Dangerous Goods Contract, or the airline may require a Material Safety Data Sheet or a UN38.3 report before they accept your shipment. These types of documents often take time to process, so make sure you prepare well in time.
Regulations are especially strict when it comes to air freight. For example: Stand-alone batteries are prohibited as cargo on passenger airplanes. Unless you have a special permit, they must be shipped by cargo airplanes. Different airlines might also have further restrictions.
Stand-alone lithium-ion batteries can only be shipped by air with a state of charge of 30% or less. Also, damaged, defective, or recalled lithium batteries are forbidden to transport by air unless you have a specific permit from the national authority and airline.
All these regulations can be quite overwhelming. Therefore, make sure to really get your head around the regulations - or take help from someone. Just remember to choose wisely and make sure they have the knowledge required to ship lithium batteries safely - from documentation, packaging, and labelling to shipping and transportation.
Ensure no batteries can come in contact with other batteries, conductive surfaces, or metal objects; Protect batteries, terminals, and switches by using caps and fully-enclosed inner packaging; Cushion stand-alone batteries or pad the equipment containing batteries inside the package; If necessary, use specialised packaging such as thermal heat protection or vents to ensure safety. (If you choose to outsource the packaging of your lithium batteries, make sure you use someone with a HazMat (Hazardous Material) certification.)
There are mainly three labels you may need for your lithium battery shipment. The first one is the Lithium Battery Class 9 Hazard Label for dangerous goods. This label is required for all fully regulated lithium battery shipments. The second is the Lithium Battery Label that includes a UN identification number and a phone number for additional information about the shipment. You may also need to have the size (power rating) of the batteries on this label. The third is the Cargo Aircraft Only Label. This label must be applied if you ship lithium-ion batteries by air that are not contained or packed with equipment.
