transport. Trained personnel must know
exactly what to do with containers to
ensure quality assurance.
PCR’s Chapter 4 notes that cargo-hold temperatures are often difficult to
predict. “Contrary to the common
myth, air transportation temperatures in
the cargo holds are not necessarily cold.
In fact, they are in many cases quite
high, despite the fact that at 10,000 ft
altitude the aircraft structure is exposed
to very cold air of about –55ºC.”
The capacity for aircraft cargo bin
temperature control varies by aircraft
type, so shippers have to know the
plane’s configuration and available
locations beforehand.
Boeing’s new Dreamliner 787s can
be equipped with segmented temperature-controlled cargo compartments
for heating and cooling, but the cost
may be prohibitive. According to one
industry source, a control system is a
$250,000 investment, with another
$250,000 for fuel consumed keeping
it airborne.
Mohr says Continental has evaluated cargo bin temp control options for
various aircraft types. The standard version of the 787 has the ability to manage temps to a certain degree in the rear
pit, with an option for front pit control. “You have to determine whether
there will be enough perishable cargo
to make that investment in the forward temperature control pit. One of
the hazards is you don’t want to
restrict your capacity to load other
cargo.”
The carrier is affixing temperature
sensors to containers in ongoing temperature studies in warehouses, on the
ramp, and in aircraft. “This is a value-added service to provide customers
with the documentation they need for
demonstrating product storage conditions,” Mohr says.
Pharma firms are in the market for
such specialized services, for meeting
FDA drug storage requirements and
best practice guidance from the U.S.
Pharmacopoeia and the Parenteral
Drug Association. In defining air carrier requirements for GMP, GSP, and
GDP, the PCR’s Chapter 17 references
the drug industry’s need for maintenance of product quality throughout
the logistics chain.
“Loss of quality is a cumulative process whereby every little break adds up.
A question that everybody involved in
the cold chain should ask is this: ‘Is the
required transit temperature well maintained during the whole process or
whilst in my custody?’” the PCR states.
The whole idea is to make sure that
all involved are aware and know what is
expected of them. ■
