Supervision, Roles, and Regulatory Compliance
Who is accountable for what
The supervisor owns the field execution of the plan: verifying notification and locates, confirming the hazard assessment is current, ensuring workers are trained and competent, and stopping work when conditions change. Candidates must understand the roles of the excavator, the facility owner, the locator, and the regulator, and know that responsibility cannot be delegated away by contract language. Traps include assuming the locator's marks transfer liability to the facility owner, or believing a verbal instruction replaces a documented procedure.
Compliance is documented
Regulatory compliance means meeting the specific requirements of the applicable statute and regulation, keeping records of notifications, locates, hazard assessments, inspections, and training, and reporting incidents as required. Questions often test whether a candidate knows that the duty of care rests with the party causing the disturbance, and that stop-work authority is a supervisory obligation, not an option.
Traps to watch
- Assuming a contractor's safety program overrides regulatory minimums.
- Failing to verify worker competency and training records before assigning tasks.
- Treating incident reporting as optional when damage is minor.
- Relying on memory instead of written procedures and checklists.
Rule of thumb
If it is not documented, assume it did not happen. Keep the notification, the locate ticket, the hazard assessment, and the inspection log together for every job.
Worked example: A supervisor finds the locate ticket expired mid-job. They stop work, re-notify, document the delay, and brief the crew before resuming, preserving all records for the file.
