OSHA recently reported three separate incidents involving improperly-secured trenches, highlighting the dangers workers face when excavating.

The first incident, which occurred in June 2016, resulted in a worker’s death.

The agency cited KRW Plumbing $274,359 after a 33-year-old employee was crushed to death as he was digging soil out of the 12-foot trench in Washington Township, Ohio when the trench walls around him collapsed - burying him in thousands of pounds of dirt. Rescue workers recovered his body a few hours later.
