A 45-year-old mixer operator was killed when he apparently lost his balance and fell through an opening in an operating mixing machine. The victim was cleaning the inside of the mixer by spraying water from above through one of three top side openings covered by protective grates. The victim had not shut the mixer off. As he stepped onto the top of the mixer, he fell through the middle opening. A worker one floor below heard a sound, saw blood coming from the machine and immediately activated the emergency shut off switch. The victim was pronounced dead at the scene. The Nebraska Workforce Development, Department of Labor's Investigator concluded that to help prevent future similar occurrences, employers should: 1. ensure that all employees are aware of the basic elements of the company's Lock-out/Tag-out program. 2. ensure that employees abide by written policy regarding Lock-out/Tag-out procedures when cleaning out mixers. 3. conduct an evaluation of the workplace and operations in the plant to determine if there are any permit-required confined spaces that require a written program. 4. develop, implement and enforce a permit required confined space entry program for employees to follow during permit required confined space entries. 5. ensure that adequate training, knowledge and skills are provided to employees to safely perform duties as necessary for permit-required confined space entries. 6. ensure that written procedures are in place and employees trained regarding notifying OSHA regarding fatalities/catastrophic events.
