Cases of Accident-related Injuries
| The cylinder head flew off during the disassembly of a breaker, flying into a worker's chest and causing serious injury. |
| A worker was disassembling a breaker set down on a working table. He loosened the nut of the cylinder head, but could not remove it. When he hit it with his hammer, the internal pressure caused the head to suddenly fly off and into his chest, causing serious injury. |
|
| Corrective Action | |
| 1. | When disassembling and assembling machines, always be fully knowledgeable about what you are doing, or work with another person who has more experience. |
| 2. | Hitting something with a hammer can either damage parts or cause debris to fly, so always use a removal jig. Leave the loosened nut attached to the bolt, rather than completely removing it. |
| 3. | Keep out of the pathway of potential gushing fluids or flying parts. |
