NCCER CORE INTRODUCTION TO BASIC
CONSTRUCTION SKILLS QUESTION BANK EXAM
ACTUAL QUESTIONS AND ANSWERS
1.
When identifying potential hazards on a construction site, which of
the following is a primary question a worker must ask to assess
equipment safety?
A. How much did the equipment cost to lease for this project?
B.How can this situation or equipment cause harm to myself or
others?
C.Is the equipment manufactured by a well-known industry
brand?
D.Has the equipment been cleaned within the last twenty-four
hours?
Rationale: Safety assessment requires evaluating the potential for
harm and the energy sources present that could cause an incident.
2. Under the Hazard Communication (HAZCOM) standard,what is the
primary responsibility of an employee regarding hazardous materials?
A.Creating the safety data sheets for all new chemicals brought to the
site.
B.Knowing the exact location of Safety Data Sheets (SDS)on the job
site.
C.Testing the chemical composition of unmarked containers
before use.
D.Training the site supervisor on the proper storage of flammable
materials.
Rationale:Employees are responsible for knowing where to find
and how to read the SDS for chemicals they use.
3. Which of the following is a fundamental rule of "Good
Housekeeping" on a construction project to prevent slips and falls?
A.Stacking all lumber in a single pile regardless of size or type.
B. Removing all scrap material and lumber with
protruding nails from work areas.
, C.Leaving spills for the specialized cleaning crew to handle at the end
of the shift.
D.Keeping all tools on the ground near the walkway for quick
access.
Rationale: Proper housekeeping involves removing hazards like
protruding nails and keeping walkways clear of debris.
4. A worker is preparing to usea power tool and needs to ensure it is
safe. What is the critical first step before connecting the tool to a power
source?
A. Checking the expiration date of the tool's original warranty.
B.Confirming that the power switch on the tool is set to the OFF
position.
C.Wiping the exterior of the tool with a damp cloth to remove dust.
D.Asking a co-worker if they have used the tool earlier that
day.Rationale: To prevent accidental startup, always ensure the switch
is OFF before plugging in a power tool.
5. When using a circular saw, why is it essential to cut on the "waste
side" of the cut mark?
A. To ensure the blade does not overheat during the cutting
process.
B.To allow for the kerf, which is the width of the cut made by
the blade.
C. To make it easier for the saw'sblade guard to retract properly.
D.To prevent the saw from vibrating excessively while in
operation.
Rationale: The "kerf" is the material removed by the blade; cutting on
the waste side ensures the final piece is the correct dimension.
6. Which component of a drill is responsible for holding the drill bit
securely in place?
A.The trigger lock mechanism.
B.The chuck.
C.The carbon brushes.
D.The torque adjustment collar.
Rationale:The chuck is the part of the drill that tightens around the
shank ofthe bit.
,7. In construction rigging, what is the specific term for the distance it
takes for one strand of wire rope to make a complete turn around the
core?
A.A splice length.
B.A lay.
C.A birdcage.
D.A braid.
Rationale: In wire rope terminology, one full rotation of a strand
around the core is defined as one lay.
8. What is the minimum passing score required to successfully
complete an NCCER knowledge assessment?
A.60%
B.70%
C.80%
D.90%
Rationale: NCCER standardized testing requires a minimum
score of 70 to pass.
9.When using a hammer drill or rotary hammer to drill into
concrete,what safety standard must be reviewed to protect against
respiratory hazards?
A.The standard for lead-based paint exposure.
B.Silica exposure standards.
C.Asbestos abatement protocols.
D.Volatile Organic Compound (VOC) regulations.
Rationale: Drilling into concrete produces silica dust,which is a
significant health hazard requiring specific safety measures.
10. A worker needs to make delicate and intricate cuts in a piece of
trim. Which type of saw is best suited for this specific task?
A.A heavy-duty reciprocating saw.
B.Ajigsaw.
C.A handheld circular saw with a framing blade.
D.A demolition saw with a diamond blade.
Rationale: Jigsaws use fine blades and are designed for intricate,
curved, or delicate cutting.
11.Which of the following defines a "combustible" liquid according to
safety standards?
A.A liquid with a flashpoint below 100°F(38℃C).
, B. A liquid with a flashpoint at or above 100°F (38℃C).
C.A liquid that remains solid at room temperature.
D.A liquid that cannot be ignited by an open flame.
Rationale: Safety classifications distinguish between flammable
(low flashpoint) and combustible (higher flashpoint) liquids.
12.What is the primary purpose of Personal Protective Equipment
(PPE) on a construction site?
A.To identify the specific trade or craft of the worker.
B.To prevent or reduce the severity of injuries from site hazards.
C.To ensure all workers look uniform while on the clock.
D.To replace the need for engineering and administrative
controls.Rationale: PPE is the final line ofdefense designed to protect
workers from physical or health hazards.
13.When climbing or descending a ladder, what is the essential safety
practice to maintain stability?
A.Carrying all necessary tools in one hand while climbing.
B.Maintaining three-point contact at all times.
C.Skipping every other rung to increase speed and efficiency.
D.Leaning as far as possible to the side to reach work areas.
Rationale: Three-point contact (two hands/one foot or two feet/one
hand) is a critical ladder safety requirement.
14.In the context of construction drawings, which type of drawing
represents the actual components and dimensions of a building
project?
A.A conceptual sketch.
B.Construction drawings (blueprints).
C.A site survey map.
D.A decorative rendering.
Rationale: Construction drawings provide the technical details needed
to build the structure.
15.What is the main connection fitting typically used for chain slings
in rigging operations?
A.A shackle.
B.A master link.
C.A turnbuckle.
