In ReviewIn Review2026-06-01 08:59:51management reviewTranscript summary: White-line marking of tank locations and photographic evidence: reminders issued and a handover sheet introduced; recent compliance has improved over the last couple of weeks. 2026-06-01: team confirmed reminders and handover sheet have improved recent compliance; ticket remains under review. Root cause check: partial - Behavioural reminders and a handover sheet have improved compliance but sustained change will need embedding into checklists and monitoring.
InitialIn Review2026-06-01 07:09:31management reviewTranscript summary: Install crews (Daniel and Stephen) not marking tank locations or providing photo evidence and signed RAMS. Identified that method statement requires white-line marking and photographic evidence prior to works but process not consistently followed. Discussed at May 6 meeting; Luke/Rob to address inclusion in communication flows and reinforce process with install leads and Sophie. Root cause check: strong - Direct discussion established that the method statement contains the requirement but it is not being followed; multiple examples cited.
