,Q1 INTERPRET AND APPLY WISCONSIN DSPS STATUTES AND ADMINISTRATIVE RULES TO
UTILITY CONTRACTOR OPERATIONS
A utility contractor is installing a new 8-inch water main in a Wisconsin
municipality. The trench depth is 6 feet, and the soil is classified as Type B.
According to OSHA 1926 Subpart P and Wisconsin DSPS adopted standards,
which protective system is minimally required if no sloping or benching is used?
A. Trench box or shield designed for the depth and soil type CORRECT
B. Hydraulic shoring with vertical uprights spaced at 8 feet
C. Aluminum hydraulic shoring with 4-foot spacing
D. No protective system required for depths under 8 feet
RATIONALE: For trenches 5 to 20 feet deep in Type B soil, OSHA requires a protective system
such as a trench box, shield, or shoring. A trench box is the most common and must be designed
for the depth and soil. Options B and C specify shoring but lack design specifics; D is incorrect
because protection is required at 5 feet or deeper.

B. Repairing a water service line from the main to the curb stop CORRECT
C. Constructing a new electrical transmission line for a utility
D. Performing landscaping around an existing utility easement
RATIONALE: SPS 305 requires a licensed utility contractor for work on water service lines from
the main to the curb stop in public rights-of-way. Private septic systems are regulated under
plumbing codes, transmission lines under PSC, and landscaping is not utility contracting.
