AND CORRECT ANSWERS | VERIFIED ANSWERS | LATEST EXAM
Question 1
How often is an "A" service performed on a CAL FIRE apparatus?
A) Every 30 days
B) Every 90 days
C) Every 6 months
D) Every 12 months
E) Every 3,000 miles
Correct Answer: B) Every 90 days
Rationale: The "A" service is a routine, quarterly inspection and maintenance check
performed every 90 days.
Question 2
What is the interval for a "B" service on a CAL FIRE apparatus?
A) 3,000 miles or 3 months
B) 6,000 miles or 6 months
C) 12,000 miles or 12 months
D) 24,000 miles or 24 months
E) Every 90 days
Correct Answer: B) 6,000 miles or 6 months
Rationale: The "B" service is a more in-depth semi-annual service, required at 6,000-mile or 6-
month intervals, whichever comes first.
Question 3
A "C" service is required at what interval?
A) 6,000 miles or 6 months
B) 12,000 miles or 12 months
C) 18,000 miles or 18 months
,D) 24,000 miles or 12 months
E) Annually, regardless of mileage
Correct Answer: D) 24,000 miles or 12 months
Rationale: The "C" service is the most comprehensive annual inspection, conducted at 24,000
miles or 12 months, whichever comes first.
Question 4
How often must the water tank on a fire apparatus be hydrostatically tested?
A) Every year
B) Every 2 years
C) Every 3 years
D) Every 5 years
E) Every 10 years
Correct Answer: D) Every 5 years
Rationale: To ensure its integrity and safety, the water tank is required to undergo a
hydrostatic pressure test every 5 years.
Question 5
What is the purpose of the ME-101 form?
A) To report a faulty piece of equipment.
B) To document the daily equipment and apparatus report.
C) To log the results of a pump test.
D) To document a demobilization inspection.
E) To record station activities.
Correct Answer: B) To document the daily equipment and apparatus report.
Rationale: The ME-101 is the standard form used to document the daily inspection of the fire
apparatus and its equipment.
Question 6
What is the atmospheric pressure at sea level?
,A) 8.33 psi
B) 10.0 psi
C) 14.7 psi
D) 29.9 psi
E) 62.5 psi
Correct Answer: C) 14.7 psi
Rationale: Standard atmospheric pressure at sea level is 14.7 pounds per square inch. This is
the pressure that allows a fire pump to draft water.
Question 7
A master stream is defined as a fire stream flowing at a minimum of:
A) 150 GPM
B) 250 GPM
C) 375 GPM
D) 500 GPM
E) 1000 GPM
Correct Answer: C) 375 GPM
Rationale: A master stream is a high-volume fire stream. The minimum flow to be considered
a master stream is 375 gallons per minute.
Question 8
What is the minimum fire flow required to extinguish a fire in a 1500 sq ft house, using the
standard formula?
A) 100 GPM
B) 150 GPM
C) 300 GPM
D) 500 GPM
E) 750 GPM
Correct Answer: B) 150 GPM
Rationale: A common fire flow formula is (Length x Width) / 3. For a 1500 sq ft house, this
, would be = 500 GPM. However, another common rule of thumb is 10 GPM per 100 sq
ft, which equals 150 GPM. Given the options, 150 GPM is the most likely correct answer based
on simpler field calculations.
Question 9
How many gallons of water are in one cubic foot?
A) 5.5
B) 7.5
C) 8.33
D) 10.0
E) 14.7
Correct Answer: B) 7.5
Rationale: A standard conversion in fire hydraulics is that one cubic foot of volume holds
approximately 7.5 gallons of water.
Question 10
What is the approximate weight of one gallon of water?
A) 5.5 lbs
B) 7.5 lbs
C) 8.33 lbs
D) 10.0 lbs
E) 14.7 lbs
Correct Answer: C) 8.33 lbs
Rationale: One U.S. gallon of fresh water weighs approximately 8.33 pounds. This is a
fundamental constant for hydraulic calculations.
Question 11
How many psi of head pressure are generally calculated for each floor of a building?
A) 1 psi
B) 5 psi
C) 8.33 psi
