Question 1 of 27070

Q

What is the primary means by which an electrical maintenance worker is protected from electrical hazards while performing work on an electrical circuit?

🔍 Key Concepts

• Hierarchy of controls for electrical safety (elimination, substitution, engineering controls, administrative controls, PPE) • Purpose and steps of lock-out/tag-out (LOTO) procedures • Difference between personal protective equipment (PPE) and actually removing the hazard

💭 Think About

• Among the choices, which option most effectively removes or isolates the electrical hazard itself rather than just warning about it or protecting the worker from its effects? • How does a proper lock-out/tag-out procedure change the status of an electrical circuit compared with simply turning equipment off? • If one control fails (for example, warning signs are ignored), which remaining control would still ensure the circuit cannot unexpectedly become energized?

✅ Before You Answer

• Verify which method actually ensures the circuit cannot be re-energized accidentally while work is being performed. • Check which option is considered an administrative/engineered safety control, not just a warning or last-line protection like PPE. • Confirm which procedure is specifically required by most electrical safety programs before maintenance on energized equipment.
