Abstract: At approximately 4:00 p.m. on June 6, 1996, Employees #1 and #2 and a coworker were on wall scaffolding, pouring and vibrating the concrete for a first story ring berm concrete wall. A bucket load of concrete was overfilled and as the crane, which had been leased by the employer to pour the wall, extended its boom radius, the overload caused it to tip over. The boom fell, striking Employees #1 and #2. Employee #1 was killed and Employee #2 was hospitalized with multiple injuries. The construction was an addition to an existing federal government hospital, to which the employees were taken after the accident.
