At approximately 10:00 AM, employees were conducting asphalt loading operations. While securing a hose atop a truck, an employee encountered a malfunction involving a plugged hose. Pressure built up within the hose and suddenly released, causing the hose to fly off the truck. The hose contacted two employees and both employees fell approximately 7 feet. Employee 1 was on top of the truck and sustained three fractured ribs and a head contusion. Employee 1 was hospitalized. Employee 2 was climbing a ladder on the truck and sustained a fractured right leg. Employee 2 was not hospitalized.
