Abstract: Employee #1 and three coworkers were installing optic fiber cable systems. Employee #1 was inside the trench giving directions to an approaching Mini-Master truck when it caved in. Employee #1 was killed. The primary factor in this accident was the use of an alternative and untested plywood shoring system instead of the available metal shoring box. Despite 10 years of experience at excavation sites, Employee #1 misjudged the hazardous nature of this operation. Because there were no daily inspections, hazardous situations were not recognized and controlled.
