The injured person had gone to shut down a company dry screen plant (Chieftain 1400) for the morning break. The normal routine when shutting down the machine is to open the side panel, switch off the conveyors and to let the engine idle for a short time to cool down before switching the engine off; whilst the engine is cooling down, the operator goes to check the readings on the belt weigher leaving the door open.
When the operator returned to the controls the door was caught by strong winds and swung towards him. His instinct was to try and stop the door from slamming shut and he put out his left hand. The door struck his hand, causing injury as a result of the impact. The injuries he sustained included a bruised finger, swollen hand and a suspected small tear in his rota cuff, keeping him off work for up to 6 weeks.
