Bulldozer entrapment incident prompts MSHA safety alert

A bulldozer entrapment incident at a coal mine prompted the Mine Safety and Health Administration (MSHA) to issue a safety alert to prevent similar incidents.

The operator’s bulldozer fell into a feeder after a bridge coal pile collapsed, engulfing the equipment and trapping him inside the cab. Swift, organized emergency response efforts led to a successful rescue. The bulldozer also was equipped with high-strength glass, oxygen bottles, and a remote shut-off for the feeder, contributing to the operator’s safe rescue.

To prevent similar incidents, MSHA offers the following best practices:

• Maintain stability by not operating bulldozers directly over feeders and avoiding draw holes;
• Stock equipment cabs with safety equipment, such as emergency oxygen and remote shut offs;
• Train miners to recognize hazards and respond to emergencies;
• Wear seatbelts at all times when operating mobile equipment;
• Use spotters to help operators working in potentially unstable environments; and
• Maintain clear communication during emergency response efforts.
