Difficulty: HardDirect Fact Retrieval

During standard replenishment of naval damage control breathing apparatuses, operators must verify that the high-pressure charging manifold maintains an intake flow rate between 18 and 22 cubic feet per minute. If the primary moisture separator filter exceeds 140 degrees Fahrenheit, technicians are instructed to engage the auxiliary cooling jacket rather than shutting down the compressor. According to standard operating procedures, desiccant cartridges must be replaced after every 50 hours of continuous pressurization, whereas particulate filter elements are inspected every 200 operational hours.

According to the passage, what specific action must technicians take if the primary moisture separator filter surpasses 140 degrees Fahrenheit?

  1. A
    Shut down the high-pressure compressor immediately
  2. Engage the auxiliary cooling jacketAnswer
  3. C
    Replace the desiccant cartridges
  4. D
    Inspect the particulate filter elements

Answer

Engage the auxiliary cooling jacket
The passage explicitly directs technicians to engage the auxiliary cooling jacket whenever the primary moisture separator filter exceeds 140 degrees Fahrenheit.

Step-by-Step Solution

1
Locate the key condition in the stem regarding the primary moisture separator filter exceeding 140 degrees Fahrenheit.
Identified the relevant sentence: 'If the primary moisture separator filter exceeds 140 degrees Fahrenheit, technicians are instructed to engage the auxiliary cooling jacket rather than shutting down the compressor.'
Direct fact retrieval requires scanning the passage specifically for the stated condition.
2
Extract the explicit mandatory procedure assigned to this condition while discarding contrasting actions and unrelated maintenance cycles.
The mandated action is engaging the auxiliary cooling jacket.
The text clearly uses 'rather than' to contrast the correct action against shutting down the compressor.
