T 2.6 Unauthorised admission to rooms requiring
protection
If unauthorised persons enter protected rooms, hazards may be entailed not
only by deliberate acts, but also by inadvertence. Disruption is caused merely
by the fact that checks must be made for potential damage as a result of the
unauthorised access. In this context, domestic rooms used for business
purposes should also be considered as security areas.
Example:
Temporary help is employed to substitute for cleaning staff on vacation. The
stand-in cleaner, without any instructions to this effect, decides to clean the
computing centre. She opens the emergency exit and thus trips the alarm.
