Onboard battery fires underscore need for meaningful action

Rotation

This week, a battery caught fire in the overhead bins on a KLM 777, Qantas became the third airline to refuse freight carriage of lithium battery shipments, and Air France’s new safety video has started warning passengers not to move their seat if they lose their phone between the cushions. It’s time to talk about lithium batteries in PEDs.

With images and video circulating from yet another battery fire in an airline cabin — this time on board KLM 876 from Amsterdam to Bangkok — air safety regulators don’t seem to be on top of the problem. A compounding factor: the cabin crew actions in the video are not entirely in accordance with IATA safety guidelines.

Answers to an in-depth series of questions from Runway Girl Network to the US Federal Aviation Administration (FAA), UK Civil Aviation Authority (CAA) and European Aviation Safety Administration (EASA), as well as to the International Air Transport Association (IATA) and the International Civil Aviation Organization (ICAO), provoked more concerns than they resolved.

RGN asked each of the regulators, the trade association and the UN body about their research into: the number and capacity of these batteries carried on board by passengers, the safety implications, any trends concerning the regulator, known airline work to ensure safety or improve passenger education, the role of airport security, work concerning the onboard response to battery fires, questions about whether locations along the lines of the Least Risk Bomb Location (LRBL) have been identified for battery fires, and what actions passengers should be taking.

To be crystal clear, our questions at this stage concerned the safety implications of lithium-ion batteries carried by many passengers for their own PED use, not their shipment as underfloor cargo on passenger jets or via dedicated cargo carriers. Equally, the specific use of batteries for mobility equipment for passengers with mobility restrictions — which is a significantly rarer occurrence with specific and understood guidelines — is not at hand here.

Paraphrasing, all regulators and stakeholder groups say they have concerns about PEDs, and in a few cases have recently started working on crew education, but are seemingly not concerned enough to be taking meaningful or effective action to raise passenger awareness.

No regulator has recent data on how many PED batteries passengers are carrying

Part of our concern is that none of the organizations RGN queried know how many batteries are taken on board aircraft.

The FAA gave a non-answer to the question of whether it has research about the number of batteries on board, which we take as a ’no’. It referred RGN to 2012 data that was the result of an APEX-CEA survey around understanding of the rules in place at that time around PED use below 10,000 feet. That report contained no information about the number of devices carried on board.

The FAA’s recent partnership with the UK CAA on a series of industry-focused education videos suggests the two principal Anglophone regulators’ work is in alignment, however.

IATA's idea that cellphones look like this is perhaps telling about the industry's level of understanding.

IATA’s idea that cellphones look like this is perhaps telling about the industry’s level of understanding.

“We have not done any research, but anecdotally it is clear the number of spare Li-ion batteries being carried by passengers is increasing,” the UK CAA told RGN. EASA also confirms it has not done research, but suggests most passengers board with between 4-5 battery-powered PEDs. ICAO did not answer the question.

IATA noted that “We don’t have any specific data for passengers, but 3-4 probably is a reasonable number. Laptop, mobile, tablet and maybe a power bank to charge the mobile phone.” 

Both those ranges seem very low for a modern traveller. US airline Delta lists 18 different types of PED on its website.

RGN invites readers to participate in a straw poll of the number of lithium-ion batteries they generally carry on board an aircraft, including (but not limited to) laptops, tablets, e-readers, phones, music players, handheld video games, noise reducing headsets, still cameras, video cameras, pocket Wi-Fi devices, fitness bands, smart watches, spare batteries, external ‘power bank’ batteries and so on, using the Twitter hashtag #HowManyPEDs

Crew information appears to be the current focus, mainly through IATA

Airline trade association IATA appears to be taking a significant lead on crew education, with its 45-page Lithium Batteries Risk Mitigation Guidance for Operators (PDF) an updated and useful guide.

New cabin crew “procedures have been developed by the IATA Cabin Safety Task Force in conjunction with ICAO and will be incorporated into the 2015 – 2016 edition of the Red Book [ICAO Emergency Response Guidance for Aircraft Incidents Involving Dangerous Goods, Doc 9481], although it is strongly recommended the new material is introduced into cabin crew procedures with immediate effect,” IATA says, including the procedures in its guide.

IATA’s guide also includes stills from a video jointly produced by the US FAA and UK CAA, aimed at airline cargo handlers and cabin crew. Released on YouTube a couple of months ago, it is educational, though perhaps a trifle stilted and with some bemusing stock video. Notably, it features some demonstrations by Virgin Atlantic crew in the airline’s cabin training mockups, and Virgin is to be praised for its participation here.

Notably, none of the organizations RGN queried were working on identifying a lithium-ion battery incident equivalent to the LRBL (Least Risk Bomb Location). Given the prospect of uncontained fire, it seems incredulous that there is not a standardised place of least risk where it is safest to fight a battery fire and secure a device under observation, all other factors taken into account.

Screen Shot 2015-03-19 at 16.36.44IATA’s guidance suggests using “a pot, jug, galley unit or toilet waste bin” as a reasonable ad hoc container, but consideration should surely be given to a standard receptacle — perhaps fireproof, fold-out and large enough — for use in containing, inundating and securing devices, and for a few standard locations within the cabin by aircraft type.

Indeed, video from the recent KLM fire would seem to show extinguishant being applied to an item on a seat rather than an item being doused or submerged as per the IATA guidance. A review of the incident needs to be conducted to determine whether procedures were followed, or whether the on-the-ground timing of the fire was just a lucky break for a 777-load of people who were put in danger by an incorrect response.

At the end of the day, crew aren’t the entire answer to the issue. Every single one of the organizations RGN queried stated that security screening of cabin baggage was not part of the solution. Yet as one of the very few touchpoints all passengers must pass, and the only point at which cabin baggage is usually screened, is this a missed opportunity?

Furthermore, “it’s likely that you will first become aware of a problem by being notified by a passenger,” the UK CAA’s video says to crew.

Of course, as anyone who’s ever struggled to get a refill on a glass of water onboard will know, levels of cabin awareness and monitoring vary widely between and within airlines. 

In the same way that crew now expect passengers to deal with disruptive or dangerous passengers, the focus needs to be on educating passengers on how to reduce the risk of a battery fire and what to do in the event one occurs.

Passenger education is still woefully inadequate

EASA told RGN that “Passengers should be aware of the potential risks posed by batteries and comply with the battery-use instructions when travelling. If they see signs of a battery being defective, they should immediately discontinue its use and properly dispose it.” 

Yet how and why do passengers develop that awareness? How many people bring their battery instructions with them — or even received instructions? What are the signs of a battery being defective? What is the ‘off off’ rather than sleep mode setting to “discontinue its use”? What is proper disposal?

IATA’s risk mitigation guidance identifies 22 ways in which airlines can inform passengers about lithium battery risk from batteries they are carrying, yet remarkably few effective campaigns have been implemented. 

Unusually, Air France’s new “flying is chic” safety video tells passengers what to do if their device falls into their seat.

“In case of the loss of an electronic device,” the airline says starting at about 3m20s in the video, “please avoid manipulating your seat and call a crew member”.

Air France’s notification is of particular interest given the known issue with the airline’s angled flat business class seats crushing phones that slip between the cushions.

And that’s it. Apart from an occasional “do you have any batteries in your checked luggage”, even frequent flyers aren’t exposed to standardised messaging or any particular public awareness campaign.

Regulators and IATA are using different measurements than manufacturers 

A good first step in passenger education would be to start measuring batteries in the same way that manufacturers and retailers do. Where any advice or warning is present, it measures batteries in watt-hours (Wh), a unit of energy, rather than milli-ampere hours (mAh), the unit of charge. 

RGN followed up with the UK CAA about the reasoning behind the decision to outline energy in Wh rather than charge in mAh as the measurement for batteries.

The UK’s CAA argued that: “Wh is the official measurement for lithium batteries, manufacturers must use it. Some retailers also use mAh however,” pointing us to this page that includes the tricky conversion between the two units that also requires the voltage of a battery — though surely even fewer people will know the voltage of their internal battery than know its charge in mAh.

Whatever its electrical engineering reasons for choosing Wh over mAh, the CAA clearly isn’t in the same reality as manufacturers or retailers, who quote charge in mAh and not energy in Wh to customers, even on the UK-specific sites with which the CAA should surely be familiar.

Samsung lists only charge. Motorola lists only charge. HTC lists only charge. And in the strongest argument of all that education is required, Apple — known for keeping “things consumers don’t really need to know” opaque — doesn’t list either energy or charge. And any search of Amazon or similar retailers for “external battery” will bring up listings with mAh and not Wh as the common currency of capacity.

IATA’s currently issued passenger pamphlet — which is dated 2010 but which this constantly travelling author has never seen in the wild — similarly lists Wh as the units of measurement. (It could also do with using a representation of a mobile phone produced in the last ten years.)

The bottom line: Passengers aren’t going to stop carrying PEDs. Batteries are getting more powerful and more numerous. Flights are getting longer and ETOPS times are being extended. The industry needs to act now before an aircraft is put in serious danger.

    As always, very interesting article.

    I can comment on a few things.

    Airbus has put in place procedures for the cabin crew on how to deal with PED lithium battery fire in the cabin. Two themes: how to deal with it, and what to do after. The first one follows IATA’s recommandations (pour water).

    The second one advise the flight crew to submerge the PED in water, in a container, and place it in a lavatory (which will be closed to the pax, for obvious reasons). This is your LRBL-like.
    My guess on the reason for that is that it’s not in the way for an evacuation, lavatories are equipped with smoke detectors which would alert the crew in case of re-ignition (which is unlikely since the device is in the water).

    Some manufacturers of equipment have been working on a foldable container that would take virtually no room in the cabin, and would come in handy when it comes to store a device after a lithium battery fire. I don’t know if any of them proposed anything at this point.

    I don’t know if Boeing published anything regarding those risks.

    I agree with you with the fact that pax should be educated. Actually, they should be educated on so many levels…
    How to store the batteries, the devices, and so on. On how to react to a fire, however, I do feel that the best reaction should be to ask for the F/As help. What we might not want is a pax pouring water on an IFE box…

    In France, we have a training course called “Equipier de Première Intervention” (which could be translated as “First Response Teammate”). It’s 90 minutes long, and you have to take it every year to keep your qualification. Basically, you learn how to use fire extinguishers (the different types against the different types of fire), and you also learn that the first thing to do is to call for help.

    While reading your article, I thought “why not have a distress call button”? But I dismissed the idea on the fact that an unruly pax would use it just to get his/her third vodka-martini. Or maybe threaten people of fines in case of misuse… I don’t know.

    A few years ago, I came across videos on youtube about aircraft maintenance. The airline was Astraeus, and the pilot representing the airline was Capt Bruce Dickinson (yeah… up the Iron!). I found these videos quite interesting and educational (and not only from an avgeek point of view). Basically, it was Bruce saying “ok, here, we are doing that on the 757, because…..”

    Maybe that could be a solution. Maybe videos in the waiting lines at the airport. You can’t have a 2-hours breifing before a flight, so I guess that pax education could be done through such “ground” solutions.

    But clearly, as you say, the industry needs to find solutions.

      Good day,

      I have read @dPm comment and find it very interesting. I think is from France and involved in aviation business. I would like, if possible, to contact him about safety / security issues on A/C and airport. Regards.

  3. FCB1200 is the original fire containment bag for Lithium-Ion battery fires in PEDs. This product was demonstrated at an IATA Cabin Conference in London in June 2012. We would be happy to discuss again the value and security of having a FCB1200 bag on all aircraft. Many corporate operators have decided to not wait for government regulation on this subject and have already put FCB1200 on board. For more information on FCB1200 or a copy of the IATA FCB1200 bulletin contact Randy Steenholdt at randy@fcb1200.com

  4. Thermal runaway is scary stuff! Cheap battery cells or inappropriate charger/cable use on the wrong device can cause it. Since most of the airplanes carry portable halon 1211 fire extinguishers, what most don’t realize is that type isn’t very effective at all at suppressing those types of fires. Halon 1301 is more affective but is typically used in fixed systems (cargo hold) and is used as a flooding agent. Lithium fire potential in the air scares me more than any other type of HAZMAT I’ve carried (including explosives, oxidizers and corrosives).

  5. The HOT-STOP® L Laptop Fire Containment Bag was first tested successfully at the FAA Tech Center in 2007. In 2008 The HOT-STOP L bag was the only containment device the FAA deemed worthy to call back for another live fire test.
    http://youtu.be/d5YssdhEt1I
    The HOT-STOP L Fire Containment bags are being used by flight departments in Corporate, Charter and Commercial airlines across North America, Europe, Asia and the Middle East. Bags are available to contain oversize laptops, standard laptops, ipads for flight decks as well as smart phones. Over 1500 kits have been put in service. Each bag comes with a lifetime performance warranty. If and HOT-STOP L kit is deployed to contain a PED simply return it with the corresponding incident report and it will be replaced free of charge
    For sales contact ray@baker-aviation.com

  6. Patent process for FCB 1200 was started in February 2007. At that point the details of the product were open for public review for any possible patent infringement. It unfortunately leaves the product open for duplication. When the FAA issued the SAFO promoting dousing the PED in water only FCB1200 discontinued the patent process knowing that all the major carriers that FCB 1200 had visited up that point would opt for the most economical approach to the problem. Since then other corporate operators have decided that the lack of government regulation was not going to stop them from being proactive and protecting their passengers and crew.

    The recent KLM incident has resulted in a flurry of inquiries into the FCB 1200 fire containment bag again. FCB has decided to place it’s full unedited Live Fire Test that was conducted in a FAA/DoD certified test facility on YouTube.

    FCB 1200 LLC. developed their fire containment bag drawing on decades of commercial, corporate, & general aviation engineering and experience. All factors from service life to ease of use & safety for a flight attendant to weight/fuel burn were considered. As stated previously we welcome the opportunity to place FCB1200 on your fleet.

  9. Fire Containment Concepts recently released the Emergency Fire Containment System (EFCS) to combat the dangers posed by lithium ion battery fires. It is not only fire containment bag it is a complete fire containment System. The EFCS is designed to not only contain extreme temperatures within it and all if not a majority of the toxic smoke, it also incorporates an automatic, self-contained suppression system which monitors the temperatures within the EFCS and deploys an lithium-ion extinguishing medium within it, only if a true fire is experienced. The EFCS is the only product which allows its user to be proactive in dealing with a potential overheating device without needlessly destroying it. The EFCS is designed and manufactured in the USA by experienced and licensed aircraft technicians. If you are looking to truly protect your aircraft, crew and passengers you have an obligation to do your research and purchase a quality Fire Containment System to deal with this obvious danger. Compare us to the other fire containment bags and make an make the best educated decision to protect your aircraft.
