Each segment is a 25 m chainage band coloured by its governing TARP state (worst credible condition across Ventilation, Ground, Water and Events). Click a segment to open the chainage popup. The highlighted segment is the current critical location.

CRITICAL LOCATION None — no monitoring data yet
Record readings in the module pages and the governing chainage will be highlighted on the strip.

Spec Module 7 — integrated longitudinal view · each chainage links Ventilation, Ground, Water, Events and governing TARP · evidence and governing reasons, not an unexplained risk score
