Sentence 4.6.8.2.(5)

Intent 1:

To exempt certain operations at stations from the application of Sentence 4.6.8.2.(2), which would otherwise implicitly require the attendant to be continuously on duty at the control console, if certain measures are taken.

These measures are to limit the probability that the attendants will be delayed in carrying out their duties in the event of an emergency, which could lead to:

• the escape or spread of liquid, which could lead to the ignition of vapour from a nearby ignition source, which could lead to harm to persons, and
• a fire or explosion hazard, which could lead to the ignition of vapour from a nearby ignition source, which could lead to harm to persons.
