Category 1: Safety Regulations and Standards (Questions 1-20)
1. What is the primary OSHA regulation governing cranes and derricks in
construction?
a) 29 CFR 1926.1400
b) 29 CFR 1910.179
c) ASME B30.5
d) ANSI/ASME B30.9
Correct Answer: a) 29 CFR 1926.1400
Rationale: OSHA's Cranes and Derricks in Construction standard is found in 29 CFR
Part 1926, Subpart CC, with 1926.1400 being the core section that outlines the
scope and application of the rule.
2. Which standard provides detailed safety provisions for the construction,
installation, operation, inspection, and maintenance of mobile cranes?
a) OSHA 1910.179
b) ASME B30.5
c) ANSI/ASSE A10.5
d) API RP 2D
Correct Answer: b) ASME B30.5
Rationale: ASME B30.5 is the "Mobile and Locomotive Cranes" safety standard,
and it serves as the primary technical reference for crane operation and safety
practices alongside OSHA regulations.
3. According to OSHA, which accessible area of an operating crane must always be
barricaded?
a) The area directly under the load
1|Page
,b) The swing radius of the rear of the rotating superstructure
c) The operator's cab
d) The area in front of the crane
Correct Answer: b) The swing radius of the rear of the rotating superstructure
Rationale: The rear of the rotating superstructure presents a significant crushing
and struck-by hazard, and OSHA mandates that this area be barricaded to prevent
personnel from entering the swing radius while the crane is in operation.
4. Under OSHA's final rule revising the Cranes and Derricks in Construction
standard (effective November 9, 2018), what must employers permanently
implement regarding crane operators?
a) Drug testing
b) Medical evaluations
c) Evaluations of crane operators
d) Annual physical training
Correct Answer: c) Evaluations of crane operators
Rationale: The 2018 final rule made operator evaluations a permanent
requirement, whereas previously the duty had been temporary with a fixed end
date. Employers must ensure operators are trained, certified/licensed, and
evaluated.
5. According to OSHA 1926 Subpart CC, what is the minimum approach distance
for a crane near power lines up to 50 kV?
a) 5 feet
b) 10 feet
c) 15 feet
d) 20 feet
Correct Answer: b) 10 feet
Rationale: Table A of OSHA 1926.1408 specifies the minimum clearance distances
for power lines. The minimum distance for lines up to 50 kV is 10 feet.
6. If a crane is working near a power line with a voltage up to 350 kV, and the
exact voltage is unknown, what minimum distance does OSHA require?
a) 10 feet
2|Page
,b) 15 feet
c) 20 feet
d) 50 feet
Correct Answer: c) 20 feet
Rationale: When the voltage is unknown but does not exceed 350 kV, a minimum
approach distance of 20 feet must be maintained as a precautionary measure.
7. When the voltage of a power line is over 350 kV and unknown, what is the
required minimum approach distance?
a) 20 feet
b) 35 feet
c) 50 feet
d) 100 feet
Correct Answer: c) 50 feet
Rationale: For voltages exceeding 350 kV, the risk of arcing and electrocution is
significantly higher. When the exact voltage is unknown, the minimum distance is
increased to 50 feet to provide a greater safety margin.
8. Under Subpart CC, what is the required timing for a "frequent" inspection of a
crane?
a) Daily to monthly
b) Monthly to annually
c) Weekly to bi-weekly
d) Only after repairs
Correct Answer: a) Daily to monthly
Rationale: A "frequent" inspection is a regular visual examination, typically
performed daily or before each shift, but at a minimum, on a monthly basis.
9. What is the timing requirement for a "periodic" inspection?
a) Daily
b) Weekly
c) Monthly to annually
d) Only after major repairs
3|Page
, Correct Answer: c) Monthly to annually
Rationale: "Periodic" inspections are more in-depth and are required at intervals
of 1 to 12 months, depending on the crane's usage, exposure to harsh conditions,
and regulatory or manufacturer requirements.
10. According to OSHA 1926 Subpart CC, what must be provided when a
telescopic boom crane is used to hoist hook-suspended personnel platforms?
a) A designated signal person
b) An anti-two-block device
c) A load moment indicator
d) An anemometer
Correct Answer: b) An anti-two-block device
Rationale: OSHA requires an operational anti-two-block (A2B) device when lifting
personnel platforms to prevent the hook block from contacting the boom tip,
which could cause a sudden loss of tension and a catastrophic fall.
11. OSHA 1926 Subpart CC mandates that all telescopic boom cranes must be
equipped with which of the following?
a) An automatic outrigger leveling system
b) A boom angle indicator
c) A two-way radio
d) A data logger
Correct Answer: b) A boom angle indicator
Rationale: Boom angle indicators are required by OSHA to provide the operator
with continuous information about the boom's angle relative to horizontal, which
is critical for referencing the crane's load chart and maintaining stability.
12. According to OSHA 1926.1427, what must an employer ensure before an
operator runs any equipment covered under Subpart CC?
a) The operator is medically fit
b) The operator has a valid driver's license
c) The operator is trained, certified/licensed, and evaluated
d) The operator has 5 years of experience
Correct Answer: c) The operator is trained, certified/licensed, and evaluated
