Case Study: On April 16, 2013, a 58-year-old worker at an underground salt mine was seriously injured and later died after he was struck by pieces of falling salt. He was working in a deep shaft with two other coworkers when the accident occurred. The coworkers were also struck by pieces of the falling material but received minor injuries.
