Respond to and record a third party strike on a polyethylene main
You are the First Response Technician on the Wodonga roster.
What has happened
At 10:40 am on 2 September a member of the public called the control centre to report a loud hissing and a strong smell of gas outside a house on Wilson Street, Wodonga. A fencing contractor had augered a post hole and struck the 63 millimetre polyethylene main. The control centre dispatched you as Priority 1. On arrival you found gas venting freely from a broken pipe, the contractor's crew still on site, and a resident standing beside the excavation. Twelve customers on the street depend on that main. The escape log and the incident register hold only the dispatch entry; the rest of the response now needs to be carried out and recorded properly.
Deliverables
- Completed escape log entry GE-26-2201
- Completed Incident and Hazard Report Form
- Permit to work application for the emergency repair
- Debrief note with recommendations

Evidence guide
Look for correct sequencing (life safety, site control, make safe, isolate, repair, restore), exclusion zone reasoning tied to detector readings and wind, a proven isolation recorded on the permit rather than assumed, accurate classification of the event as notifiable third party damage, and complete times in the log. The debrief note must identify at least one gap and a specific corrective action.
