Workers doing activities in and around trenches and excavations must be alert to the real possibility of a trench cave-in.

CARPENTER DIES IN 8-FOOT TRENCH WALL COLLAPSE
A 22-year old male carpenter died when the walls of an 8-foot excavation he was working in collapsed and completely covered him.
The employer excavated the trench going from a homeowner's basement to the homeowner's garage. The victim entered the unprotected trench and either kneeled or laid down at the bottom of the excavation to begin work. The south side of the excavation collapsed, completely burying the victim and burying a coworker up to his waist.
Emergency services were called and all employees at the job site jumped into the unprotected trench to rescue the two works. Emergency personnel arrived within minutes. The victim was removed from the trench and transported to the local hospital but he died the next day.
