An employee was preparing a boulder for demolition. The employee drilled the boulder in two places using a jackhammer and loaded the first hole with a charge. The charge was a dud so the employee flushed out the hole with pressurized water. The employee put gel into the second hole to expand and hold the charge. The second charge was also a dud. The employee flushed the second hole with pressurized water, releasing both charges. The employee drilled another hole and an unknown charge released, causing debris to go into the employee's face and arms. The employee was hospitalized.
