When operating a wheel loader near a trench, what is the minimum safe distance the loader should maintain from the excavation edge, unless otherwise specified by a competent person or engineered plan?

Question: When operating a wheel loader near a trench, what is the minimum safe distance the loader should maintain from the excavation edge, unless otherwise specified by a competent person or engineered plan?

Answer options:

• 1.0 metre (3 feet)
• The depth of the trench
• A distance equal to one-half the depth of the trench ✅ A distance determined by ground conditions and shoring

Correct answer: A distance determined by ground conditions and shoring

Explanation: Ontario Reg 213/91 and other provincial regulations require that heavy equipment be kept at a distance from an excavation edge based on ground conditions, the type of soil, and whether shoring is present, often requiring competent person assessment or engineering. There isn't a single universal minimum distance.
