A lawsuit involving the electrocution of a crane worker prompted this investigation that uncovered a loophole in the enforcement of safety laws. Texas law requires an electrical insulation device be used when cranes work near power lines. But because Texas relies on OSHA, a federal agency, to regulate and enforce workplace safety, the Texas law wasn't enforced. A spot check by reporters of numerous crane operators in the area showed they were not using the insulation device as required by law. The story prompted changes at OSHA and at the county level.
