It's a passage composed of emergency light that is used to indicate an emergency. The passage lead to a door going into the Detention chamber. In the 2002 Remake of the original 1996 game, the passage was redesigned as stairs were added in which the door is located below.
GuideEditUpon rescuing Jill/Chris from the Detention chamber (depending on who the character that is played), the game will immediately respawn into this passage. Jill/Chris will temporary follow the player at this point until reaching the B3F west corridor. If player decides to head back into the Detention Chamber again, Jill/Chris will wait here.
