Abstract: At 3:30 p.m. on January 26, 2015, Employee #1, an ironworker/welder employed by a steel erection company, was involved in erecting structural steel at a multiemployer construction site for a manufacturing plant. She was moving construction debris from an elevated grating platform approximately 17 feet above the ground. During this clean up activity, Employee #1 lost balance or caught debris in her clothing and fell from the platform. Emergency services were called, and Employee #1 was transported to the hospital. She was admitted and treated for fractures to both legs and her left wrist, and dislocation of her left elbow. She then was transferred to a rehabilitation facility for further recovery. The subsequent investigation determined that no fall protection system or device was being used. The weather was approximately 20 degrees Fahrenheit with a wind chill temperature of approximately 6 degrees Fahrenheit. Employee #1 was working inside the building, but no heat was available due to new construction.
