Operator, Rigger and Signalman Authority
Verify competent people, role separation, site briefing, machine authorization and stop-work authority before any lift.
How to study crane and rigging decisions
Practice like a lift supervisor: verify competent people, calculate the actual lift, protect the ground, inspect every lifting point, control the load path, stop for communication or weather failures, and document defects before the next shift inherits them.
Core concepts
Concept 1
Use only a competent and authorized rigger after the load, gear and lift plan are briefed.
Exam cue: competent rigger assignment
Concept 2
Stop crane movement until one designated signaler or agreed communication method is confirmed.
Exam cue: single signal authority
Concept 3
Brief the operator on the approved plan, route, hazards, ground controls, communication, exclusion zones and emergency stop signals.
Exam cue: operator site briefing

Risk pitfalls and guardrails
Treating verbal permission as written authorization.
Guardrail: Avoid verbal approval, copied readings, skipped isolation, and after-the-fact record traps.
Proceeding without recording readings, isolation, PPE, or exposure-control evidence.
Guardrail: Avoid verbal approval, copied readings, skipped isolation, and after-the-fact record traps.
Choosing a generic answer without checking state variation or the latest official notice.

Memory anchors
competent rigger assignment
Use only a competent and authorized rigger after the load, gear and lift plan are briefed.
single signal authority
Stop crane movement until one designated signaler or agreed communication method is confirmed.
operator site briefing
Brief the operator on the approved plan, route, hazards, ground controls, communication, exclusion zones and emergency stop signals.
pre-lift approval signature
Review and sign required lift-plan approvals before the lift, with changes reapproved before work continues.
Official source check
Verify eligibility, forms, fees, validity, and safety requirements with State Factories Inspectorates / Directorate of Industrial Safety and Health / Sector skill and lifting-equipment safety authorities or the current state authority notice.
Stop-work cue
If identity, authorization, isolation, PPE, exposure limits, or emergency controls are unclear, stop work and escalate.
Record cue
Exam-safe answers protect written records, competent sign-off, instrument readings, and traceable corrections.
Shortcut trap
Fast results, verbal approval, copied certificates, and undocumented adjustments are common trap answers.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
Knowledge Check (after reading)

Check-up Questions
A forklift operator is asked to attach slings for a mobile-crane lift while the assigned rigger is at lunch. The operator has no documented rigging assessment. What should the lift supervisor do?
Two workers begin giving different hand signals to the crane operator during a lift. Neither has been identified as the designated signaler. What is the operator's safest response?
Answer all questions to submit.
