What basic observation should an Operator make with his ears?
Listen for vibration, walkie-talkie, abnormal noise, housekeeping
Listen for vibration, radio, abnormal leaks, fire & alarms
Listen for leaks, radio, abnormal smell, vibration & alarms
Listen for leaks, walkie-talkie, abnormal noise, vibration & alarms
What basic observation should an Operator make with his nose?
Smell the inside of a confined space
Be aware of unusual smells
Smell the inside of an unmarked drum
Be aware of lubricating oil leak
Problems on the Plant must be reported immediately either to the Control Room Operator or to Supervisor.
True
False
At the end of the shift, a field operator should drain the battery of the walkie-talkie and allow the next shift to charge the battery.
True
False
Most operations must be shutdown or start-up in a any random order
TRUE
FALSE
What will happen if the operator fails to follow the right procedures?
Oxygen release
Natural disaster
Unqualified samples
Catastrophic release or system failure
During a routine field inspection, the pressure indicated on a process line gauge is significantly lower than the normal operating range, while upstream equipment appears to be running normally. What is the MOST appropriate first action?
Increase the pressure by adjusting the control valve immediately
Verify the gauge accuracy and check for possible blockage or leakage
Ignore the reading if no alarm is activated
Shut down the entire process line immediately
During a walk-on-line inspection, which observation requires IMMEDIATE reporting?
Missing equipment tag
Slight rust on pipe support
Dust accumulation on cable tray
Liquid dripping from a flange joint
Which of the following is considered an abnormal operating condition that should be logged and reported?
Stable flow rate with no vibration
Equipment running within design temperature
Repeated minor alarms that reset automatically
Normal operating noise level
While checking running equipment, which parameter combination is MOST critical for early fault detection?
Equipment color and label condition
Temperature, vibration, and noise
Equipment installation date
Manufacturer nameplate data
An intern notices abnormal noise from a running pump, a warm bearing housing, and a low discharge pressure. What is the BEST conclusion?
Normal operational variation
Potential mechanical failure or internal leakage
Instrumentation error only
Electrical supply instability
An intern reported abnormal vibration on a pump during his shift. On the next shift, what is his primary responsibility?
Re-adjust the pump alignment
Assume the issue has been resolved
Ignore the issue if the pump is still running
Verify whether corrective action has been taken
Which of the following radio messages is the BEST example of clear, concise, and brief communication?
“Something seems wrong with the pump and I think it’s not working properly.”
“Pump P-201 sounds different than usual, maybe vibration or something.”
“The pump is making noise and I’m not sure what to do about it.”
“Control Room, Pump P-202 showing high vibration and temperature above trend. Request instruction.”
Which situation represents a potential safety hazard that should be addressed even if no incident has occurred?
Clearly marked walkways with anti-slip surfaces
Warning signs properly displayed
Temporary hose routed across a walkway without protection
Equipment operating within design limits
Why is good housekeeping in a plant environment critical for safety?
It improves plant appearance only
It prevents slips, trips, fire hazards, and access obstruction
It increases production efficiency directly
It reduces maintenance workload
An intern observes maintenance personnel working on equipment without visible lock-out/tag-out (LOTO). What is the MOST appropriate action?
Assume LOTO is applied elsewhere
Take photos for future reference
Ignore the situation to avoid confrontation
Stop the work and report immediately to the Supervisor or Control Room
An intern notices a pressure gauge needle fluctuating rapidly beyond its usual behavior. What should he do?
Report the abnormal behavior to the Control Room or Supervisor
Ignore it if pressure returns to normal
Tap the gauge to stabilise the needle
Replace the gauge himself
Why is it dangerous to smell inside a confined space?
The air might be stale
It wastes time
The confined space may contain toxic gases or oxygen-deficient air
It affects your ability to concentrate
What is the MAIN purpose of maintaining a written log during plant operations?
To track personal tasks completed
To comply with auditing requirements only
To reduce verbal communication
To provide a record of operational data, events, and abnormal conditions for future reference
Which of the following is considered an early warning sign from plant readings?
Sudden shutdown due to trip
Gradual increase in bearing temperature over several shifts
Equipment operating at normal limits
Routine vibration within historical trend
A field reading shows a pressure increase. What is the MOST appropriate action before taking corrective steps?
Assume the instrument is faulty
Check with CCR if the change is due to process adjustments
Adjust the pressure locally
Ignore it if no alarm is active
Why should operators use their senses in addition to instrument readings?
It replaces CCR monitoring
Instruments are rarely accurate
Instruments are only for documentation
Human senses can detect issues not yet shown by instruments
An operator increases cooling water flow to reduce high lube oil temperature. What MUST be done afterward?
Assume the issue is resolved
Recheck the parameter later to confirm it returns to normal
Inform maintenance immediately
Shut down the equipment
An operator observes:
1. Rising bearing temperature
2. Slight burning smell
3. Higher vibration trend
What is the BEST conclusion?
Normal operation
Instrument malfunction only
Process change from CCR
Developing mechanical problem requiring reporting and monitoring
Why should work carried out during the shift be discussed during handover?
To demonstrate productivity
To allow the incoming operator to understand recent changes and potential follow-up actions
To avoid repeating work
To reduce written logging
