Explanation: The type of technical rescue that requires keeping all nonessential personnel, bystanders, and heavy equipment back to prevent vibrations from causing secondary cave-ins is b- trench rescue. Trench rescues are complex operations that typically involve a person trapped in a collapsed trench or excavation. The area around the incident needs to be maintained clear to avoid further collapsing.
