MSHA issued a Serious Accident Alert following an accident with an excavator at a surface crushed and broken limestone quarry.
A supervisor positioned the tracks of a hydraulic excavator in such a manner that it caused the machine to overturn as he was moving it.
Though the supervisor sustained an injury to his shoulder, more serious injuries would have been likely had he not been using his seatbelt.
- When traveling on a slope, an excavator should be driven straight up and down the slope at low speed and should not be driven across the slope
- For maximum stability while at work on a slope, the crawlers or wheels and the undercarriage of the excavator should be placed parallel to the slope and not across the slope
- Confirm that equipment is kept as far away as practical from the side of excavation
- Check to ensure the seat belt is operational. Always use the seat belt when operating the piece of equipment
- Only qualified personnel shall operate equipment. A qualified person is one who has demonstrated their ability to operate the equipment through knowledge, skills, and experience.
