Abstract: At 5:30 p.m. on May 17, 1990, Employee #1 was rigging steel that was to be installed on the roof of a structure for a track to be used with an overhead crane. The 25 ft long by 25 in. tall by 14 in. wide beam weighed 1,825 lb, and was being lifted with a nylon sling located near its center. One end of the beam rose approximately 8 to 10 ft off the floor before the opposite end began to rise. The crane operator had started to lower the beam to correct the imbalance when the beam slid approximately 6 in. in the sling. At that point, the sling was cut and the beam fell, pinning Employee #1 to the ground and killing him.
