The frequency of cable strikes in Tithegrove has been too high. Striking cables creates a serious risk of harm – serious burns and even loss of life are potential outcomes. We need to do something different to eliminate avoidable strikes from Tithegrove activities.
• Permit procedure changed to ‘Permit to break ground’ rather than dig. We have often hit unmapped very shallow cables in minor earth moving activities
• High risk excavations including around HV cables, ‘spaghetti junction’ service areas, high pressure gas and water pipes must use vacuum excavation unless not physically practical. This should eliminate the most serious risks.
• Migrating all Cat scanners to eCAT4 or gCAT4 to give us automatic recording of up to 2 years’ worth of usage data. This will help us improve operator use (mode, swing etc) and eliminate doubt regarding how the equipment was used should a strike occur.
• Absolutely no mechanical excavation within 500mm of a known service – strictly hand dig or vacuum excavation if practicable. • Increase use of sand and slab technique for connecting plot services to mains
• Be more rigorous on all sites about using and updating as built drawings of services.
• Buried Services Induction video shown to all site staff in June/July 2017
Simply fewer cable strikes, as currently measured and reported monthly in our SHE stats.
