Two employees were inside a man basket suspended by a tower crane. They were erecting a suspended scaffold for a CAT 3, which processes hydrocarbons. The suspended man basket descended about 14 feet in 1-2 seconds before stopping. The basket did not strike the ground, but one of the employees fell out of the basket and was hanging off the side. The employees were wearing fall protection at the time. Both employees were hospitalized. Employee 1 sustained four fractured ribs and contusions to the skull and thoracic area. Employee 2 sustained a facial skull fracture, epidural bleeding, and a left tibial fracture.
