The Mine Safety and Health Administration (MSHA) issued a Serious Accident Alert after a miner at a sand and gravel operation was injured while performing maintenance work on an excavator bucket. On November 3, 2017, the miner was removing the teeth from an excavator bucket with a sledge hammer. When he struck one of the teeth, a small piece of metal sheared off the sledge hammer and struck the miner in the leg.
MSHA offer the following Best Practices to help prevent this type of accident:
- Examine your work place for all possible hazards and correct them before you perform work.
- Inspect hand tools before and after use.
- Remove defective tools from service.
- Follow the manufacturers’ recommended safe work procedures for the maintenance task, and monitor work to ensure procedures are followed.
- Wear appropriate personal protective equipment (PPE) while performing work.
