Five miners nearly avoided by just minutes a 200-ton bin that crashed through the floor of the cement plant where they work.
According to the Mine Safety and Health Administration, the five miners had just left the bottom level of the facility 10 minutes prior to when the heavy bin crashed through the roof above where the workers were.
The MSHA Technical Support Division found that the 200-t0n bin fell through the floor due to abrasion. The company that owned the plant had also failed to conduct any preemptive maintenance on the 40-year-old bin.
MSHA released the following best practices to avoid a similar accident:
- Examine your work places for all possible hazards and correct them before you perform work.
- Conduct structural inspections periodically.
- Routinely examine metal structures for indications of weakened structural soundness (corrosion, fatigue cracks, bent/buckling beams, braces or columns, loose/missing connectors, broken welds, etc.).
- Keep corrosive material spillage/build-up removed from metal structures.
- Report all areas where indications of structural weakness are found.
