EXAM COVERAGE
Mobile Water Supply Operations & Water Shuttle Procedures (Core Exam Area)
This is the highest-weighted section of the Pro Board Driver/Operator – Mobile Water Supply
Certification Exam. Based on NFPA 1002 (2017 Edition), Chapters 4 and 10, candidates must
demonstrate the knowledge and skills required to safely operate a mobile water supply apparatus
(tanker/tender), establish fill and dump sites, and maintain a continuous water shuttle operation in
areas without hydrant systems. Both the written examination and practical skills evaluation emphasize
efficient rural water supply operations.
Topics include mobile water supply apparatus, tanker and tender operations, water shuttle operations,
fill site operations, dump site operations, portable tank operations, fold-a-tank deployment, jet siphons,
nurse tanker operations, relay water supply, rural water supply operations, apparatus positioning, water
transfer procedures, shuttle cycle management, and maintaining continuous water flow.
Apparatus Inspection, Preventive Maintenance & Readiness
A major exam domain emphasizing apparatus reliability and operational readiness.
Topics include daily apparatus inspections, preventive maintenance, pre-trip inspections, water tank
inspections, plumbing system inspections, pump inspections, brake inspections, tire inspections,
hydraulic system checks, lighting systems, warning devices, maintenance documentation, defect
reporting, and inspection requirements consistent with NFPA 1911.
Water Tank Construction & Apparatus Components
One of the most heavily tested apparatus knowledge areas.
Topics include water tank construction, tank capacities, baffle systems, surge control, dump valves, vent
systems, water tank plumbing, fill towers, direct tank fills, side dumps, rear dumps, jet dump systems,
piping layouts, apparatus weight distribution, center of gravity, and apparatus stability.
Pump Operations & Drafting
A major operational section covering water movement and pump operations.
Topics include centrifugal pump operation, drafting from static water sources, hard suction operations,
strainers, pump priming systems, water transfer, tank-to-pump operations, pump engagement, pressure
control, relay pumping, intake and discharge operations, pump troubleshooting, cavitation, and
maintaining water supply.
Rural Water Supply & Fire Hydraulics
A critical technical section emphasizing rural firefighting operations.
Topics include rural water supply planning, NFPA 1142 water supply concepts, fire flow requirements,
water shuttle calculations, tanker shuttle cycle calculations, flow rates, water demand calculations,
dump tank capacities, relay pumping calculations, friction loss basics, pump discharge pressure (PDP),
and sustained water supply operations.

Fill Site & Dump Site Management
One of the most important practical skill areas.
Topics include fill site layout, dump site layout, apparatus positioning, portable tank deployment, dump
valve operation, fill site safety, dump site safety, shuttle traffic flow, fill site communications, dump site
coordination, and maintaining uninterrupted water delivery.
Emergency Vehicle Driving
A heavily tested operational section emphasizing safe apparatus operation.
Topics include emergency response driving, defensive driving, braking techniques, backing procedures,
intersection safety, rural roadway operations, adverse weather driving, vehicle dimensions, vehicle
weight, liquid surge, apparatus stability, center of gravity considerations, emergency warning devices,
and safe driving practices.
Fireground Communications & Incident Coordination
Candidates must effectively communicate during water shuttle operations.
Topics include radio communications, Incident Command System (ICS), fill site communications, dump
site communications, tanker identification, shuttle coordination, accountability, emergency traffic,
standard terminology, hand signals, and communication with the incident commander.
Fireground Safety & Risk Management
A critical section emphasizing operational safety.
Topics include PPE requirements, apparatus safety zones, backing safety, spotter responsibilities,
roadway safety, scene hazards, rollover prevention, liquid surge hazards, personnel accountability,
emergency shutdown procedures, risk assessment, and operational safety during water shuttle
incidents.
NFPA Standards, Documentation & Professional Responsibilities
A regulatory and professional practice section.
Topics include NFPA 1002 Job Performance Requirements (JPRs), NFPA 1901 apparatus requirements,
NFPA 1911 inspection standards, NFPA 1142 rural water supply guidance, departmental SOPs/SOGs,
maintenance documentation, operator responsibilities, legal liability, and certification requirements.
Question 1: A mobile water supply apparatus is approaching an intersection with emergency lights and
siren activated. A vehicle approaching from the left does not appear to be yielding. What is the driver's
most appropriate action?
A) Proceed through the intersection and rely on the siren to warn the vehicle
B) Sound the air horn and proceed with caution while slowing
, Page 3 of 219
C) Stop and allow the non-yielding vehicle to pass
D) Increase speed to clear the intersection quickly
Answer: C
Rationale: The driver's primary responsibility is the safety of all persons on the roadway. When another
vehicle does not yield, the driver must stop and allow the vehicle to pass, regardless of emergency
status. This is consistent with NFPA 1002 Chapter 4 requirements for safe emergency vehicle operations
and defensive driving.
Question 2: A tanker is operating at a dump site with a 2,000-gallon portable tank. The tanker has a
2,500-gallon capacity and uses a rear dump valve with a 10-inch diameter. What is the approximate flow
rate of a 10-inch dump valve when fully open?
A) 500 gallons per minute
B) 1,000 gallons per minute
C) 1,500 gallons per minute
D) 2,500 gallons per minute
, Page 4 of 219
Answer: C
Rationale: A 10-inch dump valve typically flows approximately 1,500 gallons per minute. Large dump
valves (10-12 inches) are designed to rapidly offload water into portable tanks. Smaller valves (6 inches)
flow less, and larger valves may flow more. This is a critical concept for water shuttle cycle calculations
and maintaining flow.
Question 3: A driver/operator is preparing to draft from a static water source using hard suction hose.
What is the maximum recommended vertical lift for a pump under ideal conditions?
A) 5 feet
B) 10 feet
C) 15 feet
D) 25 feet
Answer: D
