What is a key safety procedure when working on AC equipment?

• A. Using a power supply unit
• B. Disconnecting power
• C. Testing voltage with a multimeter
• D. Simultaneously working with multiple technicians

Answer: (B)

A key safety procedure when working on AC equipment is disconnecting power. This step is critical because it ensures that there is no electrical current flowing to the unit, which minimizes the risk of electric shock or injury during maintenance or repair tasks. By disconnecting power, technicians can safely work on the equipment, inspect components, replace parts, or perform troubleshooting without the threat of accidental energization. Taking this precautionary step is a fundamental practice in maintaining a safe working environment. Other procedures, such as checking voltage with a multimeter or using a power supply, are important but should be performed only after ensuring that all power sources have been properly disconnected. Working with multiple technicians simultaneously can also introduce risks and is typically not recommended unless strict safety protocols are followed; however, the primary concern should always be addressing power disconnection first to ensure everyone's safety.
