### sec.290 Signposting of ERZ boundaries Subsection (2) applies if a person or machine can physically pass through a boundary between— a NERZ and an ERZ1; or 2 ERZ1s; or a NERZ and an ERZ0; or an ERZ1 and an ERZ0. The underground mine manager for an underground mine must ensure the actual location of the boundary is signposted in each intake airway and machine access leading into— for a boundary mentioned in subsection (1) (a) —the ERZ1; or for a boundary mentioned in subsection (1) (b) —either of the ERZ1s; or for a boundary mentioned in subsection (1) (c) or (d) —the ERZ0.
