Final answer:
Excavations or trenches can pose caught in or between hazards, which are considered to be the greatest risk related to these structures. These hazards occur when a person becomes trapped or squeezed between objects or materials, such as when a trench collapses or when heavy machinery or equipment collapses onto a person.
Step-by-step explanation:
Excavations or trenches can pose caught in or between hazards, which are considered to be the greatest risk related to these structures. These hazards occur when a person becomes trapped or squeezed between objects or materials, such as when a trench collapses or when heavy machinery or equipment collapses onto a person.
For example: If a worker is inside a trench and it collapses due to unstable soil, the person can become trapped or crushed between the collapsing walls of the trench. It is important to follow safety guidelines and regulations when working in or around excavations to prevent caught in or between hazards and ensure the safety of workers.
