The Department of Labor has revealed the findings of an OSHA investigation that discovered a concrete pipe manufacturer could have prevented an incident at one of its job sites in Florida.

According to OSHA, in March, two employees of Foley Products Company climbed inside a concrete mixer to remove hardened concrete. But as one of the workers exited the mixer, the machine restarted with the second worker still inside. That worker, whose identity has not been disclosed, was killed.
