Locator Selection, Checks and Use
Select, check and operate suitable locating equipment in appropriate modes and interpret signals cautiously.
How to prepare for Street Works operative assessment
Connect technical knowledge to observable performance: check the jurisdiction and plan, select and inspect resources, carry out each stage safely, verify the result and stop when reality departs from the applicable code.
Core concepts
Concept 1
Different locator modes and accessories detect different signals and service types, each with limitations.
Exam cue: Select the mode and accessory for the expected apparatus.
Concept 2
Equipment needs pre-use checks, current calibration or service status and a trained user.
Exam cue: Sweep beyond the proposed excavation and trace the service route.
Concept 3
Systematic sweeps, repeated scans and signal tracing are stronger than a single pass.
Exam cue: Rescan as surface and excavation conditions change.
Risk pitfalls and guardrails
Using only passive power mode.
Guardrail: Do not use a certificate, generic course note or familiar past site as a substitute for current plans, code, permission and physical verification.
Assuming no signal means no service.
Guardrail: Do not use a certificate, generic course note or familiar past site as a substitute for current plans, code, permission and physical verification.
Operating an unverified locator after a failed self-test.
Guardrail: Do not use a certificate, generic course note or familiar past site as a substitute for current plans, code, permission and physical verification.
Memory anchors
Check, Sweep, Trace
Verify the locator, search systematically and follow signals.
More Than One Mode
Use complementary detection methods where appropriate.
Signal Is Evidence
Interpret it with plans and site features.
Rescan as You Go
New exposure changes what can be detected.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
