The Mine Safety and Health Administration (MSHA) issued a Serious Accident Alert after a miner received burns at a cement facility. On August 14, 2017, a miner suffered burns to his body when hot, fine material was flushed out of a kiln dust collector hopper entry port. The miner had removed the cover plate from the hopper’s entryway and was beginning to un-choke the hopper, when the hot, fine material flowed out.
MSHA offers the following Best Practices to help prevent this type of accident:
- Wear appropriate protective clothing when working around superheated materials.
- Provide safe access to, from, and around all workplaces. Ensure that there is adequate space to work. Install and use remote cameras or similar technologies that provide a view of the interior of the hopper prior to accessing or removing the cover plate.
- Install vibrators and/or air cannons on bins to prevent material from clogging or creating an obstruction.
- Stay out of the line of fire when un-choking vessels, chutes, and hoppers.
- Develop safe work procedures when performing hazardous tasks. Always follow established work procedures from your company and the equipment manufacturer.
- Instruct supervisors, trainers, and workers on safe job procedures and how to recognize and avoid hazards.
