Questioning the answer to number 5 and would like to hear a response.
Question 5: The process of using trench boxes or other types of supports to prevent soil cave-ins is referred to as __________.
I answered shoring, and supposedly the answer is ‘shielding’. Isn’t shielding more to protect workers after a collapse, and shoring is a preventive method that would ‘prevent’ a cave-in using supports per the question?
Not directly in my wheel-house, but let me know your thoughts.
Question 5: The process of using trench boxes or other types of supports to prevent soil cave-ins is referred to as __________.
shielding
spoiling
sloping
shoring
Can someone confirm? I think of shoring as preventative of a collapse and shielding as protection in case of collapse. So I think D would be the answer, but it isn’t.
Here’s some language available about trench boxes “They aren’t designed to shore or prevent a trench wall from collapsing. Instead, they’re designed to protect workers from the pressure and weight of soil in the event of a cave-in”.
That seems to contradict the question, that says “prevent cave-ins”
