Abstract: On May 17, 2011, Employee #1 and his coworkers were operating a rock fracturing tool to remove rock from a shaft being constructed for a future parking structure. Employee #1 attempted to fire a booster charge, but the booster misfired. Employee #1 determined that a second hole should be drilled and filled with a second booster charge. As Employee #1 drilled the second hole, Employee #1 entered the first hole, and the initial misfired booster reacted and exploded. The explosion caused flying rock and debris to be disbursed throughout the shaft. Employee #1 was hit by this debris, which caused serious injuries to his eyes.
