## Narrative

while replacing pipe in matrix line, Employee used a nut with a bolt to spread a pipe to install gasket as the pipe was aligned. The nut was not threaded on the bolt completely so it deformed to a wedge shape. The wedge shape nut dislodged from the pipe as final adjustment to the pipe was made. The bolt and nut struck the employee on the left shin.
