Which method is NOT used for controlling stored energy?

• A. Bleeding hydraulic lines
• B. Leaving vents or drains open
• C. Disconnecting the power supply
• D. Locking the equipment in a storage area

Answer: (D)

Locking the equipment in a storage area is not an effective method for controlling stored energy. While securing equipment may prevent unauthorized access or use, it does not address the potential hazards associated with stored energy. Proper control of stored energy involves methods that actively neutralize or mitigate the energy present in the system, such as bleeding hydraulic lines to release pressure, leaving vents or drains open to allow for safe discharge, and disconnecting the power supply to eliminate electrical energy. Each of these methods serves to ensure that any stored energy is safely discharged or removed, minimizing the risk of accidental release during maintenance or service work.
