Abstract: At approximately 9:00 p.m. on February 3, 1989, Employee #1, age 18, who had been a meat clerk for 5 months, was attempting to operate a dumbwaiter. The mechanical door interlocks had been overridden with wooden blocks, allowing the dumbwaiter to operate with the hoistway doors opened. Employee #1 enlisted the help of a coworker, who pushed the basement control button, sending Employee #1 down. When he arrived at the basement floor, he apparently exited from the dumbwaiter, pushed the first floor button, and attempted to reenter the dumbwaiter. He was pinned between the dumbwaiter car and the top of the hoistway opening and killed.
