Cause & Consequence
- Contact with something fixed or stationary
Umbilical / pipe laying
WHAT CAUSED IT:
The power cable was not identified as a significant hazard on the Critical Work Permit or Job Safety Analysis (JSA).
CORRECTIVE ACTIONS: To address this incident, this company did the following:
Identify Work Management Scope Changes: Finding an unexpected power cable while excavating may warrant a work scope change. Once found, work should be stopped and the power cable indicated on the critical work permit or JSA to prompt additional mitigation measures (e.g. Deenergize, hydro-excavation);
Standard for Excavating Power Cables: Develop an explicit procedure for exposing an underground power cable to be included in the procedures for ground disturbance;
Never approach or touch a power cable after it has been contacted. Contact an electrician to deenergize before inspecting damage.
