A lump of hardened concrete had built up on the mixer support structure of a concrete plant.
During the loading of a mixer truck the lump became loose, falling to the ground. The lump fell and landed inside an exclusion zone, however as the lump struck the ground, it broke into several large pieces, with some travelling outside the exclusion zone. Moments before the lump fell a driver had been standing outside the exclusion zone, adjacent to where the lump fell. Although the lump would not have hit him directly, there was potential for the broken pieces to have struck him on the back of the legs.
