Annex A 7.11
Supporting utilities
Facilities are protected from power failures and other disruption caused by failures of supporting utilities.
What an assessor looks for
Show protection appropriate to your dependence, and evidence it is tested. An untested generator is an assumption.
Where it usually fails
Uninterruptible power supplies are installed and their batteries have never been load tested.
