For a boundary between an ERZ1 and an ERZ0, into which zone should the signpost face?

Explanation:
Signs at a boundary should guide people toward the safer area. Between ERZ0 and ERZ1, ERZ0 is the lower-risk zone, while ERZ1 carries a higher potential hazard. Because the aim is to direct movement away from the more hazardous area and toward safety, the signpost should be oriented to face into ERZ0. Facing into ERZ1 would point people toward the higher-risk area, which isn’t protective. The boundary exists and the guidance is to lead into the safer zone, hence the correct orientation is toward ERZ0.
