| Risk of injury. Moving parts can pinch, crush or, in extreme cases even sever extremities. | No parts of the body or limbs should be within the operating area of mechanical components when moving components. | AS00.00-Z-0009-01A | |
| Risk of burn injuries, suffocation and poisoning when working on the exhaust system and the components connected to it. Risk of suffocation and risk of poisoning caused by inhalation of gaseous and solid components of the exhaust. Risk of poisoning caused by skin contact with solid components of the exhaust. | Wear protective clothing and safety glasses. Use the extraction system. Move people out of the hazard area. | AS49.00-Z-0001-01A | |
| Risk of accident from vehicle starting off by itself when Engine running. Risk of injury (bruises and burns) resulting from working on the Engine while it is being started or when it is running. | Secure vehicle of prevent it from starting off by itself. Wear closed and sung-fitting work clothes. Do not touch hot or rotating parts | AS00.00-Z-0005-01A | |
| Risk of injury. Skin or eye injuries may result when handling hot or glowing objects. | Wear protective gloves, protective clothing and safety glasses, if necessary. | AS00.00-Z-0002-01A | |
