The executive summary of the FAA report explains the recommended changes in regulations (much of which is harmonizing the regulations with the UN Model Regulations):
In this final rule, PHMSA is revising requirements in the HMR applicable to the transport of lithium cells and batteries consistent with the UN Model Regulations, the ICAO Technical Instructions and the IMDG Code. The final rule:
(1) Replaces equivalent lithium content with Watt-hours for lithium ion cells and batteries;
(2) adopts separate shipping descriptions for lithium metal batteries and lithium ion batteries;
(3) revises provisions for the transport of small and medium lithium cells and batteries including cells and batteries packed with, or contained in, equipment;
(4) revises the requirements for the transport of lithium batteries for disposal or recycling;
(5) harmonizes the provisions for the transport of low production and prototype lithium cells and batteries with the ICAO Technical Instructions and the IMDG Code; and
(6) adopts new provisions for the transport of damaged, defective, and recalled lithium batteries.
PHMSA is not adopting proposals to: (1) Modify provisions for what constitutes a change to a battery design in the UN Manual of Tests and Criteria; (2) require lithium cells and batteries to be marked with an indication that the cell or battery design passed each of the appropriate tests outlined in the UN Manual of Tests and Criteria; or (3) limit the locations on board aircraft where shipments of lithium cells and batteries could be stowed.
@DrQuine: "(1) Replaces equivalent lithium content with Watt-hours for lithium ion cells and batteries;"
What is the limit set for the maximum "watt-hours" of Lithium batteries that could be carried in bulk in the cargo?
What about the batteries carried by the passengers inside their gadgets? There is a threat from those individual batteries as well, however small that would be...isn't it? How the fire or exposion of the batteries could be prevented?
