An employee was on a 5-foot ladder repairing a hydraulic valve and changing the internal packing. He used pressurized air to push the piston up. He then bled the fluid out of the valve. Once he removed the last bolt, pressure released, and the valve housing struck the employee in the rib area knocking him off the ladder. The employee sustained bruised ribs and back pain.
