The statute imposes a nondelegable duty upon owners, general contractors, and their agents to provide proper protection to persons working upon elevated structures. To be considered a statutory agent, the subcontractor must have been delegated the supervision and control over the work or the work area which gave rise to the aleged injury. A subcontractor who is a statutory agent may not escape liability by delegating the work to another entity.
