Lock-Out/Tag-Out, or "LOTO", is the second most cited OSHA regulation violation. The primary regulations are OSHA §1910.147 Lock-Out/Tag-Out, §1910.269 for Electric Power Generation, Transmission and Distribution and §1910.268 for Telecommunications. These rules require that all energy sources be turned off and either locked out or tagged out while service or maintenance work is being performed. By protecting the worker from accidental release of energy (electrical shock, mechanical action, heat, etc.), the rule is saving hundreds of lives.
