Tarps in excavation work help backfilling by preventing what?

• A. Rodent Intrusion
• B. Soil Compaction
• C. Water Seepage
• D. Open Holes At The End Of The Workday

Answer: (D)

Covering an excavation with a tarp during backfilling addresses the safety risk of an open hole after work stops. An uncovered trench is a real fall hazard for anyone nearby, especially at the end of the day when attention may be elsewhere. A tarp over the opening signals that the area is not safe to enter and physically helps prevent someone from unintentionally stepping into the trench. While tarps can also help shed rain or keep debris out, their primary benefit in this context is preventing open holes from being a hazard once the day ends.
