Mandatory compliance for the 56th edition of the Dangerous Goods Regulations has been in effect since January 1, 2015 but the International Air Transport Association (IATA) has just issued Addendum 2, which focuses primarily on the transportation of lithium metal and lithium-ion cells and batteries. Many carriers have already banned those items unless they are contained inside equipment. Other items included in this addendum are carrying/charging of electronic cigarettes, carrying of safety devices, dry ice, environmentally hazardous substances, internal combustion engines and radioactive materials. Many of the changes pertain to both passenger and cargo only aircraft.
