erection activities on construction sites and outlines requirements for structural steel
assembly.
Q2. What does the acronym PPE stand for?
A. Professional Precaution Ensemble
B. Protective Personnel Equipment
C. Personal Protective Equipment
D. Physical Protection Equipment
E. Procedural Protective Ensemble
CORRECT ANSWER: C. Personal Protective Equipment
RATIONALE: PPE stands for Personal Protective Equipment, which includes hard
hats, safety glasses, gloves, high-visibility vests, and other gear used to minimize
worker exposure to hazards.
,Q3. The minimum height at which fall protection is required during steel erection
is:
A. 4 feet
B. 6 feet
C. 10 feet
D. 15 feet
E. 25 feet
CORRECT ANSWER: C. 10 feet
RATIONALE: Per OSHA 1926.760, fall protection is required for ironworkers
engaged in steel erection at heights of 15 feet or more; however, during connectors'
work, the threshold begins at 2 stories or 30 feet. The general NCCER standard taught
is 10 feet for most steel erection work.
Q4. What color is typically used for OSHA-mandated safety warning signs
indicating danger?
A. Yellow and black
B. Green and white
C. Orange and black
D. Red and white
E. Blue and white
CORRECT ANSWER: D. Red and white

machinery during service or maintenance.
Q6. Before beginning work, an ironworker notices a potential hazard on the job
site. What should they do FIRST?
A. Ignore it and continue working
B. Fix it without reporting
C. Report it to a supervisor immediately
D. Wait until break time to report
E. Ask coworkers to vote on whether it is dangerous
CORRECT ANSWER: C. Report it to a supervisor immediately
RATIONALE: All workers have the right and responsibility to report hazards.
Immediate reporting allows supervisors to correct the situation before anyone is injured.
Q7. A Safety Data Sheet (SDS) provides information about:
A. Crane load capacities
B. Daily production targets
C. Blueprint specifications
D. Hazardous chemical properties and safe handling
E. Employee payroll information
CORRECT ANSWER: D. Hazardous chemical properties and safe handling
RATIONALE: SDS (formerly MSDS) documents provide critical information about
chemical hazards, first aid, PPE requirements, and proper handling procedures for
hazardous substances.
, Q8. What is the purpose of a Job Hazard Analysis (JHA)?
A. To track worker productivity
B. To identify and control hazards before work begins
C. To document employee attendance
D. To estimate material costs
E. To plan the work schedule
CORRECT ANSWER: B. To identify and control hazards before work begins
RATIONALE: A Job Hazard Analysis (JHA) systematically breaks down job tasks
to identify potential hazards and prescribe controls, preventing injuries before they
occur.
Q9. Hard hats used by ironworkers must comply with which standard?
A. ANSI Z87.1
