Should I dig into a bank at a 45-degree angle?

Digging into a bank at a 45-degree angle is recommended for ensuring stability and safety. This angle helps prevent collapses and provides a safer working environment when carrying out excavation work. A 45-degree angle allows for gradual slopes, which are more stable than steeper approaches. Steeper angles can lead to erosion and ground failure, posing a danger to workers.

When excavating, particularly in construction or hoisting operations, following proper angles is essential for maintaining site safety. The other choices imply conditions under which one might or might not dig at a 45-degree angle, but maintaining this angle is generally a best practice, regardless of external factors such as weather or directives, given that it addresses safety concerns inherent to the task.
