The change made in this addendum allows the use of
R744 as a secondary coolant or refrigerant in certain situations.
It allows limited releases of R744 to the atmosphere during
unusual events, such as an extended power failure with
coincident heat gains that would otherwise cause system pressures
to rise above component design pressures. Refrigerant
vented to atmosphere during a power failure is likely to be a
"de minimus" quantity compared to losses from other causes
such as normal leakage in even the best maintained commercial
and industrial systems.
