Question: According to Ontario Reg 213/91 concerning construction projects, what is a key safety requirement when creating or working near stockpiles higher than 2.4 metres (8 feet)?

Answer options:

• The pile must be fenced off completely to prevent access.
• A formal geotechnical analysis must be completed for every stockpile. ✅ The pile must be shaped and maintained to prevent collapse and unauthorized entry, with specific attention to the angle of repose.
• Only dozers are permitted to work on stockpiles of this height.

Correct answer: The pile must be shaped and maintained to prevent collapse and unauthorized entry, with specific attention to the angle of repose.

Explanation: Ontario Reg 213/91 requires that stockpiles of excavated material, especially those over 2.4 m, be managed to prevent collapse and restrict unauthorized access. This includes maintaining slopes at a safe angle of repose.
