What does the regulation state regarding the management of trenches by excavators?

1. Trenches must be left open for inspection

2. Excavators must attend to trenches at all times

3. Trenches can be left unattended as long as they are marked

4. Excavators are not required to be present during closing hours

The correct answer is: Excavators must attend to trenches at all times

The regulation emphasizes that excavators must attend to trenches at all times to ensure safety and compliance with safety standards. This requirement is put in place to prevent accidents, as open trenches can pose significant risks to both workers and the public. An unattended trench may lead to falls, unauthorized access, or other hazardous situations. By mandating that excavators be present, the regulation ensures continuous oversight, allowing quick responses to any issues that may arise, such as shifts in the trench walls, water accumulation, or the presence of pedestrians or vehicles nearby. The importance of having eyes on the worksite cannot be overstated, as it enforces accountability among workers and promotes a safe working environment. In contrast, leaving trenches open for inspection, marking them, or being absent during closing hours does not adequately address the inherent dangers associated with an open trench, which could compromise safety protocols.
