Abstract: At 10:50 a.m. on November 19, 1998, Employee #1, a refrigeration mechanic, and his foreman were installing refrigeration line hangers in the overhead of a food store under construction. Both employees were working from self-propelled mobile elevating work platforms rented from a local distributor especially for this task. The floor was concrete with several three-foot-square openings left unpaved for future floor drains. Employee #1's platform right rear wheel rolled into one of the drain depressions which caused the platform to roll over on its right side. As the 15-foot elevated platform fell, it struck a 33-inch high stack of drywall stored in the vicinity of the depression. This caused Employee #1 to be thrown down to the concrete surface. Emergency Services was called and the paramedics transported Employee #1 to a local trauma center, but he was pronounced dead on arrival due to head injuries.
