Soreness, pain, hurt-nonspecified injury

Employees were cleaning and removing sludge from a pit. A vacuum truck was vacuuming the sludge out of the pit. An employee was using a pressure washer to help make the sludge more flowable. Another employee was holding the vacuum hose to evacuate the sludge when his foot became stuck in the sludge. The employee operating the pressure washer used it around the other employee's stuck foot in an attempt to free it. The water from the pressure washer penetrated through the top of the employee's boot, injuring the fourth toe of his left foot. He was hospitalized.
