Difficulty: MediumDirect Fact Retrieval

During scheduled maintenance of dry-chemical fire suppression canisters, technicians must inspect the nitrogen propellant pressure gauge. If the ambient temperature is 70°F, the gauge indicator must rest squarely within the green zone between 195 and 205 psi. A reading below this range indicates slow leakage through the discharge valve seal, requiring complete depressurization and cylinder replacement. Conversely, if ambient temperatures exceed 90°F, thermal expansion can cause a temporary pressure rise without indicating system failure.

According to the passage, what problem is indicated when the pressure gauge reads below the specified range at 70°F?

  1. A
    Thermal expansion of the nitrogen propellant
  2. Slow leakage through the discharge valve sealAnswer
  3. C
    Complete depletion of the dry-chemical agent
  4. D
    Clogging within the ambient temperature sensor

Answer

Slow leakage through the discharge valve seal
The passage explicitly declares that when the gauge indicator falls below the 195–205 psi range at 70°F, it indicates slow leakage through the discharge valve seal.

Step-by-Step Solution

1
Locate the condition specified in the stem within the passage text.
Found the phrase referring to readings below the normal range at 70°F.
Direct fact retrieval requires scanning for the exact situational context stated in the prompt.
2
Extract the explicit factual cause directly tied to that condition.
The text states that a reading below this range indicates slow leakage through the discharge valve seal.
The correct response must mirror the explicit factual claim made by the author without extrapolation.
