Abstract: At approximately 10:15 a.m. on January 19, 1988, a concrete finishing crew was taking a break while the concrete placement crew was waiting for more concrete on the second level of a building addition under construction. Employee #1 walked down the stairs to the first level and headed out from under the second level just as a 10-foot section of 5-inch steel pipe was being dropped down by the placement crew. Employee #1 apparently heard no one call out a warning and was struck on the head and left shoulder by the pipe. He suffered a head laceration requiring 12 stitches and a bruised left shoulder. Causal factors were a lack of adequate communication and that no protective helmet was worn by Employee #1.
