What is the correct sequence for removing shoring from a trench?

Top to bottom
Side to side
Bottom to top
Randomly

The correct answer is: Bottom to top

The correct sequence for removing shoring from a trench is bottom to top. This method is essential for maintaining the stability of the trench during the removal process. By starting at the bottom, the forces acting on the surrounding soil and the trench walls are gradually reduced, which minimizes the risk of collapse or shifting earth. When shoring is removed in this manner, it allows the soil to settle properly without sudden changes in pressure that could occur if shoring is removed from the top down. Conversely, removing shoring from the top to bottom or side to side could lead to instabilities and increase the likelihood of accidents. Random removal lacks any strategic approach, which could also compromise safety standards. Thus, following a bottom to top sequence is crucial for preserving safety in trench operations.
