Lockout Tagout (LOTO) aims to control hazardous energies by developing blocking methods for the energies and safety procedures to instruct workers on how to perform their tasks safely. This work aims to use LOTO methodologies to develop a safety procedure for a machine located in a factory that fabricates metal cans used for the packaging. Initially, the needed resources to implement this methodology were assessed, such as the improvement of the tagging system that identifies the equipment and the energy blocking points, and the acquisition of equipment to block and dissipate the energy. The machine was analyzed, documenting the tasks performed by workers on the ma-chine and the energies involved in those tasks, as well as the implementation of the needed changes and improvements. Next, a safety procedure was developed and implemented for the machine, showcasing the energies that need to be blocked, and a guide on how to perform each task safely. The implemented changes and safety procedure had minimal effect on the duration of tasks and were able to reduce the injury rates seen on the machine.
