,California C-38 - Refrigeration QUESTIONS
Question 1
Which shared area connects these two activities: “Preparing final bids and project
proposals” and “Estimating labor hours, crew sizes, and labor overhead”?
A. Refrigeration System Installation
B. Compliance with Cal/OSHA General Industry and Construction Safety Orders (Title 8)
C. Refrigeration System Repair
D. Planning and Estimating
Correct Answer: D
Full Explanation: Both activities contribute to Planning and Estimating. One concerns
Preparing final bids and project proposals; the other concerns Estimating labor hours, crew
sizes, and labor overhead. Their shared purpose is more specific than the alternative areas.
Question 2
Two responsibilities must be distinguished: (1) Emergency response procedures
and first aid protocols; (2) Cleaning and servicing condensate drains and filters.
Which pair names their respective areas in that order?
A. 1: Refrigeration System Maintenance; 2: Compliance with Cal/OSHA General Industry and
Construction Safety Orders (Title 8)
B. 1: Compliance with Cal/OSHA General Industry and Construction Safety Orders (Title 8); 2:
Compliance with Cal/OSHA General Industry and Construction Safety Orders (Title 8)
C. 1: Refrigeration System Maintenance; 2: Refrigeration System Maintenance
D. 1: Compliance with Cal/OSHA General Industry and Construction Safety Orders (Title 8); 2:
Refrigeration System Maintenance
Correct Answer: D
Full Explanation: For “Compliance with Cal/OSHA General Industry and Construction Safety
Orders (Title 8)”, the relevant focus includes “Emergency response procedures and first aid
protocols”. For “Refrigeration System Maintenance”, the relevant focus includes “Cleaning and
servicing condensate drains and filters”. The distinction is between the two stated
responsibilities; exchanging them would assign each requirement to the wrong focus.

Question 3
A reviewer is considering “Inspecting electrical terminals, wiring, and safety
controls” as an example of “Refrigeration System Maintenance”. Which additional
example provides a second, distinct contribution to the same focus?
A. Fabricating, bending, routing, and brazing refrigerant lines and piping
B. Analyzing system operating parameters, pressures, and temperatures
C. Determining load calculations, system sizing, and equipment specifications
D. Tracking refrigerant usage, recovery, and disposal records per EPA standards
Correct Answer: D
Full Explanation: Tracking refrigerant usage, recovery, and disposal records per EPA
standards adds another aspect of Refrigeration System Maintenance, alongside Inspecting
electrical terminals, wiring, and safety controls. Both contribute to that area, so the second
example expands the coverage without introducing an unrelated objective.
Question 4
Which pair of allocations would need to be exchanged to correct both of these
notes: “Planning and Estimating” has “Fabricating, bending, routing, and brazing
refrigerant lines and piping”, while “Refrigeration System Installation” has
“Calculating material quantities, equipment costs, and specialty parts”?
A. Move both activities to Refrigeration System Maintenance
B. Move Calculating material quantities, equipment costs, and specialty parts to Planning and
Estimating and Fabricating, bending, routing, and brazing refrigerant lines and piping to
Refrigeration System Installation
C. Keep Calculating material quantities, equipment costs, and specialty parts with Refrigeration
System Installation and move Fabricating, bending, routing, and brazing refrigerant lines and
piping to Refrigeration System Maintenance
D. Keep Fabricating, bending, routing, and brazing refrigerant lines and piping with Planning and
Estimating and move Calculating material quantities, equipment costs, and specialty parts to
Refrigeration System Maintenance
Correct Answer: B
Full Explanation: For “Planning and Estimating”, the relevant focus includes “Calculating
material quantities, equipment costs, and specialty parts”. For “Refrigeration System
Installation”, the relevant focus includes “Fabricating, bending, routing, and brazing refrigerant
lines and piping”. Exchanging the two activities restores both direct relationships; moving them
to Refrigeration System Maintenance would leave at least one of the original allocations
unresolved.

Question 5
A reviewer is considering “Pass The C-38 License Exam In 5 Easy Steps” as an
example of “Compliance with Cal/OSHA General Industry and Construction Safety
Orders (Title 8)”. Which additional example provides a second, distinct
contribution to the same focus?
A. Ensuring compliance with local building codes, environmental regulations, and energy
standards (Title 24)
B. Fabricating, bending, routing, and brazing refrigerant lines and piping
C. Ventilation requirements in enclosed or confined spaces during brazing and chemical usage
D. Ensuring ongoing compliance with Title 24 energy efficiency standards and mechanical codes
Correct Answer: C
Full Explanation: Ventilation requirements in enclosed or confined spaces during brazing and
chemical usage adds another aspect of Compliance with Cal/OSHA General Industry and
Construction Safety Orders (Title 8), alongside Pass The C-38 License Exam In 5 Easy Steps.
Both contribute to that area, so the second example expands the coverage without introducing
an unrelated objective.
Question 6
Which shared area connects these two activities: “Installing valves, gauges, filters,
driers, and controls” and “Installing refrigeration equipment”?
A. Planning and Estimating
B. Refrigeration System Maintenance
C. Refrigeration System Installation
D. Refrigeration System Repair
Correct Answer: C
Full Explanation: Both activities contribute to Refrigeration System Installation. One concerns
Installing valves, gauges, filters, driers, and controls; the other concerns Installing refrigeration
equipment. Their shared purpose is more specific than the alternative areas.
