Sample NV C-5 Concrete Practice Questions

Try these sample questions to review concepts for the NV C-5 Concrete exam. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Per OSHA 1926.701(b), what must be done with protruding reinforcing steel that employees could fall onto or into?
A.Guard it to eliminate the impalement hazard
B.Paint the bar ends orange
C.Bend every bar to 45 degrees
D.Cover only bars taller than 6 feet
Explanation: OSHA 1926.701(b) requires all protruding reinforcing steel, onto and into which employees could fall, to be guarded to eliminate the impalement hazard. Manufactured rebar caps rated for impalement, wooden troughs, or bending bars out of the fall path are accepted methods when they actually prevent impalement. Color paint alone does not guard the steel.
2Under OSHA 1926.701(d), who may ride a concrete bucket?
A.The finish foreman only
B.No employee
C.Anyone wearing a harness
D.The crane signal person
Explanation: OSHA 1926.701(d) states that no employee shall be permitted to ride concrete buckets. The bucket is a material hoist, not a personnel lift. Use a personnel platform or access that meets Subpart L or M instead.
3On a typical C-5 building project, OSHA 1926.501 requires fall protection when an employee is exposed to a fall of how many feet or more?
A.6 feet
B.4 feet
C.10 feet
D.15 feet
Explanation: OSHA 1926.501(b)(1) sets the general construction trigger at 6 feet. That applies to wall-form work decks, elevated slabs, and leading edges unless a more specific Subpart Q or scaffold rule is stricter. Guardrails, personal fall arrest, or safety nets are the usual systems.
4When a handheld power saw is used to cut concrete, OSHA 1926.1153 Table 1 first requires which silica control?
A.A paper dust mask only
B.An integrated water feed that continuously wets the blade, or an equivalent listed dust-collection method
C.Dry cutting with no controls if the cut is under 1 minute
D.A fan aimed at the operator
Explanation: OSHA 1926.1153 Table 1 lists handheld power saws and requires a saw with an integrated water-delivery system that continuously feeds water to the blade, or a listed dust-collection alternative, operated per the manufacturer. Wet cutting is the ordinary C-5 control on slab and pavement saws. A loose paper mask is not Table 1 compliance.
5Per OSHA 1926.703(a)(2), what formwork documents must be available at the jobsite?
A.Drawings or plans, including all revisions, for jack layout, formwork (including shoring), working decks, and scaffolds
B.Only the ready-mix ticket
C.A verbal OK from the pump operator
D.The original bid estimate
Explanation: OSHA 1926.703(a)(2) requires the current formwork drawings — jack layout, forms, shoring equipment, working decks, and scaffolds, including revisions — to be on site. Inspectors and the crew use those drawings to confirm shores, braces, and pour-rate limits. A batch ticket does not replace the formwork plan.
6OSHA 1926.701(e) restricts work under elevated concrete buckets. Which statement is correct?
A.No employee shall work under concrete buckets while they are being elevated or lowered into position
B.Employees may stand under a loaded bucket if they wear hard hats
C.Only finishers may work under the bucket
D.The rule applies only to crane-and-bucket pours over 20 cubic yards
Explanation: OSHA 1926.701(e)(1) prohibits working under concrete buckets while they are being raised or lowered. 1926.701(e)(2) also requires routing elevated buckets so the fewest employees are exposed. A hard hat does not protect against a dropped bucket or a gate failure.
7Unless the excavation is in stable rock and a competent person finds no cave-in hazard, OSHA 1926.652 requires a protective system in trenches starting at what depth?
A.2 feet
B.5 feet
C.4 feet
D.8 feet
Explanation: OSHA 1926.652(a) requires cave-in protection in excavations 5 feet or deeper unless the excavation is entirely in stable rock. Shallower trenches still need protection if a competent person sees a cave-in hazard. C-5 footing and grade-beam trenches commonly hit this trigger.
8A 6-foot-deep footing trench is occupied. Per OSHA 1926.651(c)(2), a ladder or other safe egress must be located so that no more than how much lateral travel is required?
A.10 feet
B.25 feet
C.15 feet
D.50 feet
Explanation: OSHA 1926.651(c)(2) requires a stairway, ladder, ramp, or other safe means of egress in trench excavations 4 feet or more in depth, located so employees need no more than 25 feet of lateral travel. A 6-foot trench is past the 4-foot trigger, so a ladder is required at least every 50 feet of trench if people work the full length.
9OSHA 1926.702(j) requires bull-float handles to be nonconductive or insulated when they might contact which hazard?
A.Energized electrical conductors
B.Fresh concrete splash
C.Hot weather above 90°F
D.Epoxy-coated bars
Explanation: OSHA 1926.702(j) requires bull-float handles used where they might contact energized electrical conductors to be nonconductive or covered with a nonconductive sheath. Long metal handles on a wet slab are a shock path to overhead services and temporary power. The rule is electrical, not a finish-quality rule.
10OSHA 1926.703(e) allows removal of wall or elevated-slab forms only after which determination?
A.The employer determines the concrete has gained sufficient strength, based on the drawings/specifications or on appropriate ASTM strength tests
B.The surface is hard to a thumbnail
C.Four hours have passed, regardless of temperature
D.The pump hose has been washed out
Explanation: OSHA 1926.703(e)(1) forbids removing forms and shores (except slabs on grade and slip forms) until the employer determines the concrete can support its own weight and superimposed loads. That determination must follow the plans and specifications or appropriate ASTM tests that show enough strength. A thumbnail scratch is not an ASTM method. ACI 318-14 26.5.4 separately requires protection from freezing until at least 500 psi, which is a cold-weather durability floor, not a stripping strength for elevated work.
