8.2.1 A system
to monitor the well-being of crew members entering refrigerated spaces
is to be provided.

system is to be such that at a predetermined time, after initiation,
the crew member(s) receives warning that the Surveyors must indicate
their well-being by accepting the warning.
8.2.3 The
system is to be designed and arranged such that only an authorised
person has access for enabling and disabling it and setting the appropriate
intervals, and such that it cannot be operated in an unauthorised
manner.

to be possible to acknowledge the warning by means of illuminated
switches situated near the access doors or hatches of each refrigerated
space or chambers within the space.
8.2.5 In the
