Which of these will be accomplished on a daily inspection?

• A. Verify system air pressure
• B. Replace the air filter
• C. Inspect the anti-fog coating
• D. Recalibrate the timing mechanism

Answer: (A)

Daily inspections focus on quickly confirming that essential operating parameters are within the required range. Verifying system air pressure is the best choice because the pneumatic system that powers controls, actuators, and safety devices relies on a stable, within-spec pressure. Checking the pressure daily helps detect leaks, regulator issues, or compressor problems before they impact operation or safety. If the pressure reads low, maintenance actions can be taken promptly to prevent equipment malfunction. Replacing the air filter is a maintenance task tied to a schedule or differential pressure, not a daily check. Inspecting an anti-fog coating isn’t a standard plant parameter inspection and pertains more to visibility aids than to normal operating readiness. Recalibrating the timing mechanism is a calibration activity that requires specific procedures and isn’t something performed during routine daily checks.
