fitted into devices, respectively, may be carried aboard an aircraft.
PHMSA received one comment from the FCHEA requesting that we amend
§ 175.10(a)(19) to allow fuel cell cartridges containing flammable gas in Division 2.1 and
fuel cells containing water reactive materials in Division 4.3 in checked passenger
baggage. PHMSA did not propose changes to the provisions allowing for the checking of
limited types of fuel cells in the NPRM, and consider this request to be outside the scope
of this rulemaking.
PRBA noted in their comments to the NPRM that the 2013-2014 ICAO Technical
Instructions contain a provision that authorizes passengers to carry portable medical
electronic devices aboard passenger aircraft with lithium metal batteries containing up to 8
grams of lithium metal. While this amendment should be added to the HMR it was not
included in the August 15, 2012 NPRM and the public has not been provided notice of any
intent to add a new exception for lithium battery-containing portable medical devices in §
175.10 or afforded the opportunity to provide us with written data, views, or arguments to
aid our decision. As the FAA Modernization and Reform Act of 2012 requires
harmonization in this instance, we will propose to adopt this exception in a future
rulemaking.
Part 176
Section 176.2
Section 176.2 provides definitions of terms specifically as they pertain to Part 176.
In this final rule, PHMSA is adopting various revisions to the vessel stowage and
segregation requirements specified in Part 176. As part of these changes certain
terminology must be defined.
