Safe Zone

From Zelda Wiki.org

Link running towards a Safe Zone

In the Temple of the Ocean King and in the Ghost Ship, there are areas called Safe Zones in Phantom Hourglass. While in these Safe Zones, the Phantoms lurking the dungeon cannot harm Link, and time does not drain from the Phantom Hourglass. There are red jars, however, that when broken, create a small Safe Zone. Link must make full use of these to complete his quest.

One known false floor disguised as a safe zone can be found on B8 of the Ocean Temple^[1].
