PRACTICE QUESTIONS WITH VERIFIED ANSWERS &
RATIONALES | LATEST UPDATE
DOMAIN 1: HAZARD IDENTIFICATION AND CONTROL (Questions 1-60)
Question 1
Which OSHA standard primarily governs construction fall protection
requirements?
A. 29 CFR 1910 Subpart D
B. 29 CFR 1926 Subpart M
C. 29 CFR 1926 Subpart L
D. 29 CFR 1910 Subpart I
Correct Answer: B
Rationale: OSHA 29 CFR 1926 Subpart M specifically addresses fall protection
requirements in the construction industry.[reference:3] 29 CFR 1910 covers
general industry standards, not construction-specific fall protection.
Question 2
What is the minimum required breaking strength for a vertical lifeline used in a
Personal Fall Arrest System (PFAS)?
A. 2,000 pounds
B. 3,000 pounds
C. 5,000 pounds
D. 10,000 pounds
Correct Answer: C
Rationale: OSHA 29 CFR 1926.502(d) requires that vertical lifelines have a
minimum breaking strength of 5,000 pounds. This ensures adequate strength to
arrest a fall safely.

,Question 3
At what height must fall protection be provided for workers on a construction
site?
A. 4 feet
B. 6 feet
C. 10 feet
D. 15 feet
Correct Answer: B
Rationale: OSHA 29 CFR 1926.501(b)(1) requires fall protection at 6 feet for
construction workers. This is one of the key distinctions from general industry,
where the threshold is typically 4 feet.
Question 4
What is the maximum permitted free fall distance for a worker using a Personal
Fall Arrest System (PFAS)?
A. 2 feet
B. 4 feet
C. 6 feet
D. 10 feet
Correct Answer: C
Rationale: OSHA 29 CFR 1926.502(d)(16)(iii) limits the free fall distance to 6 feet
for a PFAS. This ensures the system can arrest the fall without exceeding the
allowable forces on the worker's body.
Question 5
What is the maximum allowable deceleration distance for a PFAS?
A. 2.5 feet
B. 3.5 feet
C. 4.5 feet
D. 6.0 feet
2
,Correct Answer: B
Rationale: OSHA 29 CFR 1926.502(d)(16)(iv) limits the deceleration distance to 3.5
feet. This ensures the fall arrest system stops the worker before they hit a lower
level or the ground.
Question 6
What is the maximum arresting force that a PFAS can impose on a worker?
A. 900 pounds
B. 1,800 pounds
C. 2,500 pounds
D. 5,000 pounds
Correct Answer: B
Rationale: OSHA 29 CFR 1926.502(d)(16)(ii) limits the maximum arresting force to
1,800 pounds. This protects the worker from injury caused by excessive force
during fall arrest.
Question 7
Which of the following is NOT an acceptable anchor point for a PFAS?
A. A structural steel beam
B. A concrete column
C. A guardrail system designed for the purpose
D. A ventilation duct
Correct Answer: D
Rationale: Anchor points must be capable of supporting at least 5,000 pounds per
employee attached. Ventilation ducts are not designed to support this load and
are not acceptable anchor points.
Question 8
What is the maximum distance a guardrail system's top rail can deflect under a
200-pound load?
3
, A. 1 inch
B. 2 inches
C. 3 inches
D. 4 inches
Correct Answer: C
Rationale: OSHA 29 CFR 1926.502(b)(3) requires that guardrail systems be capable
of withstanding a 200-pound load applied in any direction and that the top rail
deflects no more than 3 inches.
Question 9
What is the height requirement for a guardrail system's top rail?
A. 30 inches
B. 36 inches
C. 42 inches
D. 48 inches
Correct Answer: C
Rationale: OSHA 29 CFR 1926.502(b)(1) requires the top rail of a guardrail system
to be 42 inches (plus or minus 3 inches) above the walking/working level.
Question 10
What is the maximum mesh opening size for a guardrail system's midrail?
A. 12 inches
B. 19 inches
C. 24 inches
D. 30 inches
Correct Answer: B
Rationale: OSHA 29 CFR 1926.502(b)(2) requires that midrails be installed when
there is no wall or parapet at least 21 inches high, and the opening between the
top rail and the working surface must not exceed 19 inches.
