Which of these factors may increase the risk of a cave-in?
A. Lack of vibration
B. Changes in weather
C. Soil that has never been dug before
D. Piling soil away from the excavation
Answer (2)
Cave-ins in excavation sites can be caused by several factors including changes in weather, untested soil conditions, and improper soil management. Each of these factors affects the stability of the excavation site, increasing the risk of a collapse. Proper safety measures must be taken to mitigate these risks. ;
Changes in weather, untested soil conditions, and improper soil management can all increase the risk of cave-ins at excavation sites. Therefore, the correct choice is B, C, and D as they each contribute to higher instability risks. In contrast, a lack of vibration typically reduces these risks.
