B) Competent Person
C) Project Engineer
D) Safety Officer
Answer: B
Explanation: OSHA defines a Competent Person as one who is capable of identifying hazards and has the
authority to take corrective action, including approving shoring designs.
**Question 2.** In West Virginia, how many hours in advance must a contractor request a locate ticket
through the 811 system for a standard residential project?
A) 24 hours
B) 48 hours
C) 72 hours
D) 96 hours
Answer: B

Exam
Explanation: The tolerance zone is a buffer area around a marked utility; excavation within this zone
requires extra precautions such as hand‑digging.
**Question 4.** Which soil classification (per OSHA) has the highest stability and therefore allows the
steepest allowable slope?
A) Type A (Stable Rock)
B) Type B (Cohesive Soil)
C) Type C (Granular Soil)
D) Type D (Mixed Soil)
Answer: A
Explanation: Type A soils, including stable rock, provide the greatest inherent stability, permitting the
steepest slopes (up to 75 % or 3.75 : 1).
**Question 5.** When calculating the volume of a rectangular trench 30 ft long, 4 ft deep, and 3 ft
wide, what is the correct cubic‑yard result?
A) 10 yd³
B) 12 yd³
C) 14 yd³
D) 16 yd³
Answer: B
Explanation: Volume = 30 × 4 × 3 = 360 ft³. Convert to cubic yards: 360 ÷ 27 = 13.33 yd³ ≈ 12 yd³
(rounded to the nearest whole yard for typical estimating).
**Question 6.** Which of the following methods is most appropriate for dewatering a shallow
excavation with a high water table?
A) Well points

Exam
B) Dewatering trenches
C) Sump pumps placed at the bottom of the trench
D) Freeze‑wall technique
Answer: C
Explanation: For shallow excavations, a sump pump at the lowest point efficiently removes water
without the complexity of well points or freeze‑walls.
**Question 7.** Under WV Code §24‑C, which of the following is an exemption from the 811
notification requirement?
A) Installation of a new water main
B) Emergency repairs to a gas line
C) Construction of a new residential driveway

A) Red
B) Yellow
C) Blue
D) Orange
Answer: A
Explanation: Red indicates electric power, high‑voltage lines, and related facilities.

**Question 9.** A Competent Person inspects an excavation and discovers a crack in the shoring
timber. What is the required immediate action?
A) Continue work and monitor the crack hourly
B) Reinforce the timber with additional bracing
C) Halt work in the affected area until the shoring is repaired or replaced
D) Notify the site supervisor but keep workers in place
Answer: C
Explanation: OSHA requires the Competent Person to stop work in any area where protective systems
are compromised.
**Question 10.** What is the maximum allowable distance between a ladder and the edge of an
excavation for safe egress, according to OSHA Subpart P?
A) 5 ft
B) 7 ft
C) 10 ft
D) 15 ft
Answer: B
Explanation: OSHA mandates that ladders be placed no more than 7 ft from the edge of an excavation to
reduce the risk of falling.
**Question 11.** Which calculation determines the required spoil‑pile setback distance from the edge
of an excavation?
A) Height of the spoil pile multiplied by 1.5
B) Height of the spoil pile multiplied by 2
C) Height of the spoil pile multiplied by 0.75
D) Height of the spoil pile multiplied by 3
