An excavator operator on a municipal project site is performing a trench excavation for a water main replacement. The trench is parallel to an active roadway, separated by only 2 metres (6.5 feet). What protective measure, beyond standard trenching practices, is specifically required to ensure public and worker safety from the active roadway?

Question: An excavator operator on a municipal project site is performing a trench excavation for a water main replacement. The trench is parallel to an active roadway, separated by only 2 metres (6.5 feet). What protective measure, beyond standard trenching practices, is specifically required to ensure public and worker safety from the active roadway?

Answer options:

• A flag person must be stationed at each end of the trench.
• The trench must be backfilled immediately after pipe installation to minimize exposure. ✅ Appropriate traffic control measures, including barriers and signage, must be in place.
• All workers in the trench must wear high-visibility vests at all times.

Correct answer: Appropriate traffic control measures, including barriers and signage, must be in place.

Explanation: When working near active roadways, robust traffic control measures, including physical barriers, clear signage, and potentially flag persons, are essential to protect both the public and on-site workers from traffic hazards.
