Sample NV C-3A Carpentry and Repairs Practice Questions

Try these sample questions to test your NV C-3A Carpentry and Repairs exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under OSHA 1926.501, at what height must a carpenter on an unprotected walking/working surface be protected from falling by a guardrail, safety net, or personal fall arrest system?
A.6 feet (1.8 m) or more above a lower level
B.4 feet (1.2 m) or more above a lower level
C.10 feet (3.1 m) or more above a lower level
D.15 feet (4.6 m) or more above a lower level
Explanation: OSHA 1926.501(b)(1) requires fall protection on construction walking/working surfaces with an unprotected side or edge 6 feet or more above a lower level. The same 6-foot trigger applies to holes, leading edges, and most carpentry work at floor and roof decks. Scaffolding uses a different 10-foot trigger under 1926.451(g)(1).
2What is the required top-edge height of an OSHA construction guardrail system above the walking/working level?
A.36 inches plus or minus 3 inches
B.42 inches plus or minus 3 inches
C.48 inches plus or minus 2 inches
D.39 inches exactly
Explanation: OSHA 1926.502(b)(1) sets the top rail at 42 inches plus or minus 3 inches (39 to 45 inches). Midrails go halfway between the top rail and the walking surface when there is no wall at least 21 inches high. The top rail must resist 200 pounds without failure.
3When a portable ladder is used to reach an upper landing, how far must the side rails extend above that landing unless the top is secured and a grasping device is provided?
A.1 foot (0.3 m)
B.2 feet (0.6 m)
C.3 feet (0.9 m)
D.4 feet (1.2 m)
Explanation: OSHA 1926.1053(b)(1) requires portable-ladder side rails to extend at least 3 feet above the upper landing used for access. If that extension is impossible, the top must be secured to a rigid support and a grab device provided. The 3-foot extension gives a worker something to hold while stepping on or off the ladder.
4What guard is required on a portable circular saw used for framing or finish cuts?
A.Guards above and below the base plate that automatically return to cover the blade
B.A fixed upper hood only, with the lower blade left exposed
C.A riving knife with no blade cover
D.No guard if the saw is used for less than 15 minutes
Explanation: OSHA 1926.304(d) requires portable, power-driven circular saws to be equipped with guards above and below the base plate or shoe. The lower guard must automatically and instantly return to the covering position when the tool is withdrawn from the work. Kickback and blade-contact injuries are among the most common carpentry tool injuries.
5When cutting treated lumber, composite trim, or gypsum with a power saw, which personal protective equipment is required in addition to a hard hat where falling-object hazards exist?
A.A cotton dust mask only, with no eye protection
B.Hearing protection only if the saw is used indoors
C.Steel-toe boots only
D.Eye and face protection meeting OSHA 1926.102
Explanation: OSHA 1926.102 requires eye and face protection when machines or operations present a flying-particle hazard. Circular saws, miter saws, and grinders throw chips, grit, and fastener fragments. Hearing protection under 1926.52 is also often needed, but eye protection is the first required control for cutting operations.
6A 24-inch by 24-inch floor opening is cut for a plumbing chase on a framed second floor. What does OSHA 1926.502 require of the hole cover?
A.Any scrap plywood is acceptable if it overlaps the hole by 1 inch
B.The cover must support twice the maximum intended load, be secured, and be color-coded or marked HOLE or COVER
C.The cover must support the weight of one worker only and may be left unmarked
D.A warning cone next to an uncovered hole meets the standard
Explanation: OSHA 1926.502(i) requires hole covers to support at least twice the weight of employees, equipment, and materials that may be imposed on them, to be secured so they cannot be displaced, and to be color-coded or marked with the word HOLE or COVER. 1926.501(b)(4) also requires protection from falling through holes more than 6 feet above a lower level.
7Unless designed by a qualified person with a safety factor of at least two, what minimum strength must a personal-fall-arrest anchorage have per attached employee?
A.1,800 pounds (8 kN)
B.3,600 pounds (16 kN)
C.5,000 pounds (22.2 kN)
D.10,000 pounds (44.5 kN)
Explanation: OSHA 1926.502(d)(15) requires each personal-fall-arrest anchorage to support at least 5,000 pounds per employee attached, or to be designed, installed, and used as part of a complete PFAS with a safety factor of at least two under a qualified person. Dee-rings and snaphooks are also 5,000-pound tensile components. Body belts have not been acceptable for fall arrest since January 1, 1998.
8At what height must each employee on a scaffold be protected from falling to a lower level?
A.More than 10 feet (3.1 m) above a lower level
B.6 feet (1.8 m) above a lower level
C.4 feet (1.2 m) above a lower level
D.15 feet (4.6 m) above a lower level
Explanation: OSHA 1926.451(g)(1) requires fall protection for each employee on a scaffold more than 10 feet above a lower level. That 10-foot scaffold rule is an exception to the general 6-foot construction trigger in Subpart M. Supported scaffolds with a height-to-base ratio greater than 4:1 must also be guyed, tied, or braced.
9A portable extension ladder reaches a 16-foot eave. Using the OSHA 4:1 setup, how far from the wall should the base of the ladder be placed?
A.2 feet
B.4 feet
C.6 feet
D.8 feet
Explanation: OSHA 1926.1053(b)(5)(i) requires non-self-supporting ladders to be used so the horizontal distance from the top support to the foot is about one-quarter of the working length (the 4:1 rule). For a 16-foot height to the support, the base is 16 ÷ 4 = 4 feet out. Side rails must still extend 3 feet above the landing used for access.
10A temporary job-built stair used during framing has four risers. What is the minimum height of a stairrail installed after March 15, 1991, measured from the tread at the nosing?
A.30 inches
B.34 inches
C.42 inches
D.36 inches
Explanation: OSHA 1926.1052(c)(1) requires a stairrail or handrail on stairways with four or more risers or more than 30 inches of rise. Stairrails installed after March 15, 1991, must be at least 36 inches from the top of the rail to the tread, in line with the riser face at the nosing. If the top of the stairrail also serves as a handrail, the height must be 36 to 37 inches.
