Plant Operator Selection System Test Plant Operator Selection System Reading Comprehension 2

Question 1

Read the following passage and answer the question.

"Before starting the pump, the operator must verify that the inlet valve is fully open, the discharge valve is partially open, and the seal water is flowing. Failure to confirm these conditions may result in equipment damage."

What must the operator check LAST before starting the pump?

Accepted Answer

Seal water is flowing

Answer

The passage lists three checks in order: inlet valve, discharge valve, then seal water — seal water is the last item listed.

Question 2

Read the following safety notice and answer the question.

"Lockout/tagout procedures MUST be followed whenever maintenance is performed on electrical equipment. No exceptions are permitted. Workers who bypass these procedures are subject to immediate termination."

Which statement is best supported by this notice?

Accepted Answer

Lockout/tagout compliance is mandatory with no exceptions

Answer

The notice explicitly states 'No exceptions are permitted,' making compliance unconditionally mandatory.

Question 3

Read the following passage and answer the question.

"The cooling tower operates most efficiently when water temperature entering the tower does not exceed 95°F. When inlet water temperature rises above this threshold, fan speed should be increased incrementally until the temperature returns to the acceptable range."

According to the passage, what should an operator do when inlet water temperature is 98°F?

Accepted Answer

Increase fan speed incrementally

Answer

The passage states that when temperature exceeds 95°F, fan speed should be increased incrementally to restore acceptable range.

Question 4

Read the following procedure excerpt and answer the question.

"Step 1: Don personal protective equipment. Step 2: Isolate the chemical feed line. Step 3: Open the drain valve. Step 4: Collect a sample in a clean container. Step 5: Close the drain valve and restore the line."

What happens immediately AFTER the drain valve is opened?

Accepted Answer

A sample is collected in a clean container

Answer

Step 4 — collecting a sample — immediately follows Step 3, which is opening the drain valve.

Question 5

Read the following passage and answer the question.

"Boiler feedwater quality must be monitored continuously. High dissolved oxygen content accelerates corrosion of boiler tubes, while excessively low pH causes acid attack on metal surfaces. Both conditions shorten equipment lifespan significantly."

According to the passage, which TWO factors are harmful to boiler tubes?

Accepted Answer

High dissolved oxygen and low pH

Answer

The passage specifically identifies high dissolved oxygen (causing corrosion) and low pH (causing acid attack) as harmful to boiler equipment.
