Guys the problem is not just in cargo, there have been many instances of the Lithium batteries in Personal Electronic Devices (PED's) catching fire. Trouble is you do not fight them as you would a conventional chemical, electric or metal fire as they can easily catch fire after you have knocked down the fire. The best fire extinguisher to use on them is water not Halon, as water not just puts out the fire but also cools the battery cells.
We have produced a free short online course that we have made available to anyone. The course is aimed at Flight & Cabin Crew but is also recommended for personnel that handle baggage and cargo. You can view the course at
