Sets supplying safety services (such as fire and smoke control, evacuation equipment and lifts) and essential services (life-preserving, airport safety and traffic control and other essential equipment) must, where required, maintain supply long enough to evacuate everyone to safety; have enough fuel for the immediate emergency purpose; have fire resistance for an adequate time by construction or installation; be permanently connected; not be affected by failure of the normal supply; and not be used for other purposes unless permitted. Whether an emergency supply is needed at all is outside the Standard.
This control maps to 2 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 2 it maps to, and the evidence behind each claim, over MCP and REST.
