The Mine Safety and Health Administration (MSHA) issued a Serious Accident Alert after a miner was injured while working on a crusher at a limestone operation. On March 26, 2018, a miner was removing an electric motor from a jaw crusher when the lifting chain slipped, causing the motor to drop and strike the miner. The miner received a serious head injury when he fell 7.5 feet from the jaw crusher work platform. The platform’s handrail was not in place at the time of the accident.
MSHA offers the following Best Practices to help prevent this type of accident:
- Protect openings near travelways by installing railings, barriers, or covers.
- Ensure covers or railings protecting temporary access openings are secured in place at all times when an opening is not being used.
- Provide readily visible warning signs that clearly display the nature of the hazard and any protective action required.
- Wear fall protection where there is a danger of falling.
- Establish and discuss safe work procedures. Identify and control all hazards to finish the job safely.
- Train all persons, especially workplace examiners, to recognize and understand safe job procedures before beginning work. Communicate and correct hazards in a timely manner.
