,Q1. A contractor plans to excavate a trench 12 feet deep in Type C soil. Which
protective system is required by OSHA 29 CFR 1926.652, and what is the maximum
allowable slope for a temporary slope?
A. Benching with a maximum slope of 1.5H:1V
B. Shoring with a maximum slope of 1H:1V
C. Sloping with a maximum slope of 1.5H:1V
D. Shielding with a maximum slope of 2H:1V
Correct Answer: C. Sloping with a maximum slope of 1.5H:1V
Rationale: OSHA requires Type C soil to be sloped at a maximum angle of 1.5H:1V (34
degrees) when using sloping as the protective system. Benching is not allowed in Type C
soil. Shoring and shielding do not involve sloping; they are support systems that do not
require a slope.
Why Wrong:
A - Benching is prohibited in Type C soil because it is unstable and can collapse.
B - Shoring is a support system, not a slope, and the slope ratio is irrelevant.
D - Shielding is a trench box, not a slope, and the slope ratio does not apply.
Reference: OSHA 29 CFR 1926.652; Wisconsin Administrative Code SPS 328
Q2. A utility contractor receives a dig ticket for a project in a municipality with a
one-call system. Which of the following actions is REQUIRED before excavating,
according to Wisconsin's Diggers Hotline law (Wis. Stat. § 182.0175)?
A. Contact the municipality to obtain a separate excavation permit.
B. Wait at least 3 working days after the locate request before digging.
C. Ensure all utilities have marked their facilities or been cleared.
D. Perform a private locate for all non-member utilities.
Correct Answer: C. Ensure all utilities have marked their facilities or been cleared.
Rationale: Wisconsin law requires that before excavating, the contractor must ensure that
all utility operators have either marked their facilities or cleared the area. Waiting the
required time (often 3 working days) is necessary, but the key obligation is that locates
must be performed or cleared. A separate municipal permit may be needed but is not the
primary requirement under the one-call law.
Why Wrong:
A - A municipal permit is a separate requirement, not the core obligation under the
one-call statute.
B - Waiting alone is insufficient; the contractor must confirm locates are completed or
cleared.
D - Private locates are only for facilities not covered by the one-call system, and the
statute does not require the contractor to perform them unless the utility is not a
member.

Q3. During trenching operations, atmospheric testing reveals oxygen concentration at
18.5%. What is the required action per OSHA 29 CFR 1926.651(g) and 1926.652?
A. Continue work, as 18.5% is acceptable for most work.
B. Stop work and evacuate personnel immediately.
C. Increase ventilation and retest after 30 minutes.
D. Provide respiratory protection and continue with caution.
Correct Answer: B. Stop work and evacuate personnel immediately.
Rationale: OSHA defines an oxygen-deficient atmosphere as one with less than 19.5%
oxygen. At 18.5%, the atmosphere is deficient, and work must stop, personnel evacuated,
and the trench must be made safe (e.g., ventilation) before re-entry. The other options do
not address the immediate hazard adequately.
Why Wrong:
A - 18.5% is below the OSHA threshold of 19.5% for oxygen deficiency.
C - Ventilation may be part of the corrective action, but immediate evacuation is
required first.
D - Respiratory protection is not a substitute for evacuation and correction of the
hazard.
Reference: OSHA 29 CFR 1926.651(g); 1926.652
Q4. A contractor is installing a water main parallel to an existing sewer line. The
Wisconsin Administrative Code (SPS 382) requires a minimum horizontal separation
of 10 feet. Due to site constraints, the separation is only 6 feet. What condition must
be met to allow this reduced separation?
A. The water main must be placed in a watertight conduit.
B. The sewer line must be upgraded to SDR 35 PVC.
C. The water main must be constructed of ductile iron with mechanical joints.
D. A variance from the Department of Natural Resources is obtained.
Correct Answer: A. The water main must be placed in a watertight conduit.
Rationale: Wisconsin SPS 382 allows reduced separation if the water main is placed in a
watertight conduit (e.g., a sleeve) that extends 10 feet beyond the crossing or parallel
section. This prevents contamination if a leak occurs. Upgrading materials or obtaining a
variance are not the standard allowances.
Why Wrong:
B - Upgrading sewer pipe does not address the contamination risk from a water main
leak.
C - Ductile iron alone does not provide the required protection; a watertight conduit is
needed.
