Photo 5 shows the structure as it was positioned when the PSA team arrived at the
incident site. The structure had then been lowered to the deck and had folded over
so that the beams which had supported the deck gratings are sticking up in the
photo. It was part of this structure which struck slinger 1.
Photo 5 is from the PSA team’s inspection of the incident site.

north in relation to where it was hanging before the incident.

6 Direct and underlying causes
6.1 Direct causes
The direct causes of the incident were that the structure moved out of control at the
same time as the injured person moved into the exposed area when the structure was
released from the first ratchet strap. This led to them being crushed between the
structure and the tote tank frame.
