1. Which OSHA regulation primarily governs fall protection
requirements for ironworkers engaged in structural steel erection?
A. OSHA 29 CFR 1910 Subpart D
B. OSHA 29 CFR 1926 Subpart R
C. OSHA 29 CFR 1926 Subpart K
D. OSHA 29 CFR 1910 Subpart S
Answer: B. OSHA 29 CFR 1926 Subpart R
Rationale: OSHA 29 CFR 1926 Subpart R specifically addresses steel
erection activities, including fall protection, hoisting, connectors,
decking, and structural stability requirements unique to ironworking.
2. During steel erection, what is the primary purpose of drift pins?
A. Permanently secure structural members
B. Weld structural members together
C. Align bolt holes before installing bolts
D. Tighten high-strength bolts
Answer: C. Align bolt holes before installing bolts
Rationale: Drift pins temporarily align bolt holes in connected members
to facilitate bolt installation. They should never be used as permanent
load-bearing devices.

, 3. Which bolt installation method requires tightening until the nut
rotates a prescribed amount after snug-tight condition is achieved?
A. Turn-of-nut method
B. Torque wrench method
C. Calibrated wrench method
D. Direct tension indicator method
Answer: A. Turn-of-nut method
Rationale: The turn-of-nut method develops the required bolt pretension
by rotating the nut a specified fraction of a turn after reaching snug-
tight condition.
4. A structural beam measures W24×84. What does the number 84
represent?
A. Beam depth in inches
B. Beam flange width
C. Weight per linear foot
D. Steel yield strength
Answer: C. Weight per linear foot
Rationale: In the designation W24×84, "84" indicates the beam weighs
84 pounds per foot.
5. Which welding process is most commonly used for field welding
structural steel?
A. Gas welding
B. Shielded Metal Arc Welding (SMAW)
C. Resistance welding
D. Friction welding
2
,Answer: B. Shielded Metal Arc Welding (SMAW)
Rationale: SMAW is widely used because it performs well outdoors,
tolerates moderate wind, and requires relatively simple equipment.
6. What is the minimum number of bolts generally required to secure
a structural member before releasing the crane load?
A. One bolt
B. Two bolts
C. Four bolts
D. Six bolts
Answer: B. Two bolts
Rationale: OSHA generally requires at least two bolts per connection,
properly installed before releasing the load, unless engineering
specifications require more.
7. What instrument is commonly used to verify structural column
plumbness?
A. Vernier caliper
B. Transit or total station
C. Micrometer
D. Thickness gauge
Answer: B. Transit or total station
Rationale: Survey instruments such as transits and total stations provide
precise measurements for column alignment.
8. Which steel shape is primarily designed to resist bending loads?
3
, A. Angle
B. Wide-flange beam
C. Plate
D. Rod
Answer: B. Wide-flange beam
Rationale: Wide-flange beams efficiently resist bending due to their
large section modulus and moment of inertia.
9. A beam camber is intentionally fabricated to:
A. Reduce steel weight
B. Increase bolt strength
C. Offset anticipated deflection
D. Improve corrosion resistance
Answer: C. Offset anticipated deflection
Rationale: Camber provides an upward curve so the beam becomes
level under expected service loads.
10. What does the term "snug-tight" mean for structural bolts?
A. Maximum bolt tension
B. Finger tight only
C. Tightened until connected parts are firmly in contact
D. Tightened with hydraulic equipment
Answer: C. Tightened until connected parts are firmly in contact
Rationale: Snug-tight is the initial condition before final pretensioning
methods are applied.
11. Which rigging component has the highest efficiency?
