1What is the primary purpose of a firefighter breathing-air replenishment system (FARS) installed in a building?
A.To provide a permanently piped source of breathing air so firefighters can refill SCBA cylinders inside the structure
B.To supply standpipe water to firefighter hose lines on upper floors
C.To pressurize stairwells as a smoke-control system
D.To replace the building fire-sprinkler system in high-rise occupancies
Explanation: A FARS is a building-installed high-pressure air standpipe. It delivers breathing air to interior fill panels or fill stations so firefighters can refill self-contained breathing apparatus (SCBA) cylinders during operations instead of hauling bottles up and down the building. It is not a water standpipe, smoke-control system, or sprinkler substitute.
2The official allowed reference for the Nevada C-1J Systems to Replenish Breathing Air for Firefighters examination is which document?
A.International Fuel Gas Code, 2021
B.NFPA 13 Standard for the Installation of Sprinkler Systems, 2019
C.Uniform Plumbing Code, 2018
D.International Mechanical Code, 2018
Explanation: PSI Candidate Information Bulletin 270 lists Uniform Plumbing Code, 2018 as the allowed in-center reference for the open-book C-1J examination. Firefighter breathing-air replenishment systems are treated in UPC Appendix F. Study from that edition, not from later UPC printings or from unrelated fire-sprinkler or mechanical codes.
3A FARS is best described as which of the following?
A.A building-installed high-pressure air standpipe that delivers breathing air to interior fill points
B.A portable cascade of SCBA bottles carried on the first-due engine
C.A medical-oxygen manifold serving patient rooms
D.A low-pressure shop-air system for pneumatic tools
Explanation: Industry practice and UPC Appendix F treat FARS as a fixed, building-installed distribution system — an air standpipe. Exterior fire-department connection panels, stainless distribution tubing, and interior fill panels or stations make breathing air available throughout the structure. It is not a truck-mounted cascade, a medical-oxygen system, or ordinary shop air.
4Per 2018 UPC Appendix F Section F 501.2, each building or structure with a firefighter breathing-air replenishment system shall have how many exterior fire-department connection panels?
A.A minimum of two panels
B.One panel, located at the main entrance
C.One panel per stairwell, with no other minimum
D.Four panels, one on each building face
Explanation: F 501.2 requires a minimum of two exterior fire-department connection panels. The two-panel rule gives the mobile air operator a second hookup if fire, collapse, or apparatus placement blocks one side of the building. A single main-entrance panel does not meet the appendix.
5Per UPC Appendix F Section F 501.6, the front of an exterior fire-department connection enclosure shall be marked with which wording?
A.FIRE DEPARTMENT CONNECTION
B.SCBA FILL — AUTHORIZED PERSONNEL ONLY
C.FIREFIGHTER AIR SYSTEM
D.HIGH-PRESSURE NITROGEN
Explanation: F 501.6 requires the front of the enclosure to be marked FIREFIGHTER AIR SYSTEM in contrasting letters not less than 2 inches high with a 3/8-inch brush stroke. Ordinary FDC water-connection lettering, a generic SCBA warning, or a nitrogen label would misidentify the panel to arriving companies.
6Per UPC Appendix F Section F 501.3, each exterior fire-department connection panel shall be located on opposite sides of the building and within what distance of an approved roadway or driveway, unless the Authority Having Jurisdiction approves another location?
A.50 feet
B.25 feet
C.100 feet
D.150 feet
Explanation: F 501.3 places the two exterior panels on opposite sides of the building and within 50 feet of an approved roadway or driveway, or at other locations the AHJ approves. The 50-foot limit keeps the mobile air unit hose lay short and the operator in a defendable, accessible position.
7Per UPC Appendix F Section F 501.3, clear, unobstructed access to the front of an exterior fire-department connection panel shall include at least which of the following?
A.A 3-foot radius and a 90-degree approach
B.A 4-foot-wide sidewalk with no radius stated
C.A 6-foot radius and 180-degree clear access
D.Firefighter access from a ladder only
Explanation: F 501.3 requires a minimum 6-foot radius and 180-degree clear, unobstructed access to the front of the panel. That space lets the mobile air operator stage hoses and fittings without working in traffic or against a wall. A 3-foot radius or a ladder-only approach does not meet the appendix.
8Per UPC Appendix F Section F 501.3, an exterior fire-department connection panel may be installed in which of the following ways?
A.Attached to the building, or on a remote monument at the exterior, and weather-resistant or inside a weather-resistant enclosure
B.Only inside the fire-pump room
C.Only on the roof, to keep it away from vehicle traffic
D.Only below grade in a vault to conceal the high-pressure fittings
Explanation: F 501.3 allows the panel to be attached to the building or set on a remote exterior monument. The panel itself must be weather-resistant or secured inside a weather-resistant enclosure. Roof-only, pump-room-only, and below-grade-vault-only placements are not the appendix locations.
9Per UPC Appendix F Section F 501.4, the exterior fire-department connection cabinet shall be constructed of what minimum material?
A.Not less than 18-gauge carbon steel or equivalent, with a coating or other means to protect the cabinet from corrosion
B.22-gauge galvanized sheet metal
C.3/4-inch plywood lined with drywall
D.Cast-iron valve box with a plastic lid
Explanation: F 501.4 requires a metal cabinet of not less than 18-gauge carbon steel or equivalent, plus a coating or other corrosion protection. Light 22-gauge sheet, wood, and cast-iron valve boxes do not meet the cabinet construction rule.
10Per UPC Appendix F Section F 501.5, when an exterior fire-department connection panel is located in an area subject to vehicle traffic, what is required?
A.Impact protection
B.A painted stripe on the pavement only
C.A speed bump 50 feet away
D.Relocation of the panel to the roof
Explanation: F 501.5 requires impact protection where the panel is exposed to vehicle traffic. Bollards or an equivalent barrier keep a delivery truck or fire apparatus from crushing the high-pressure cabinet. Paint stripes and distant speed bumps are not impact protection.
