Fractures

A crew was priming a cement pump. To help grout start moving through the pump, they ran a few gallons of water through it and started it in forward until the grout reached the end of the first 20-foot hose section. They then placed the pump in neutral, connected the next 20-foot hose with hose clamps, and began pumping again. As the grout traveled through the second hose, it clogged. The pump was put in neutral just as the hose kicked, and the motion traveled down the length of the hose. An employee was holding the end of the hose when it kicked up and struck him in the left side of the face, causing fractures.
