During valve operation testing, which practice helps prevent accidental discharge?

• A. Wear PPE during testing
• B. Maintain area clear
• C. Lockout/tagout if required
• D. Verify discharge outlets are unobstructed and safe

Answer: (C)

Preventing accidental discharge during valve operation testing comes from isolating the energy that could move or release the valve. Lockout/tagout involves securing the energy sources so the valve cannot be actuated while you’re testing, and it requires the authorized person to remove the lock or tag after verifying the work is complete. This directly stops a valve from being opened or released unintentionally, which is the main risk during testing. Wearing PPE protects you if something does release, but it doesn’t stop the discharge from happening. Keeping the area clear and ensuring discharge outlets are unobstructed are important safety measures for overall conduct and flow, but they don’t provide the control needed to prevent a discharge caused by accidental actuator movement. Lockout/tagout is the focused control that addresses the risk at the source.
