4. D. 100 lb

The correct answer is: D. 100 lb

The approximate weight of falling dirt involved in trench collapses is around 100 pounds per cubic foot. This value is significant because it highlights the potential danger and the heavy load that can be exerted by soil during a collapse. Understanding this weight is crucial for EMTs and other emergency responders, as it assists in assessing the risks and implementing appropriate safety measures during rescue operations. Recognizing that each cubic foot of soil can weigh up to 100 pounds underscores the importance of having proper trench safety protocols in place to prevent such incidents from occurring. Knowledge of this weight can also inform responders about the possible difficulty in lifting or moving materials and the risk of suffocation or injury to individuals trapped in a collapse.
