With machines becoming increasingly more complex as technology advances and automation becomes an increasingly important aspect of all types of manufacturing processes, the complexity of engaging with machinery also increases, which can lead to increased risk and injury rates. LOTO, or lockout/tagout, aims to control hazardous energies by developing blocking methods for the energies present in industrial equipment and to create safety procedures instructing workers on how to perform their tasks safely.

In this context, this work aims to use LOTO methodologies to develop a safety procedure for three different machines located in a factory specializing in the manufacturing of metal cans used for packaging. Some preliminary research identified the resources needed for the implementation of LOTO methodologies, such as the improvement of the tagging system that identifies the equipment and the energy blocking points, and the acquisition of the equipment needed to correctly block and dissipate the energy present in the machines. Following these tasks, each of the three machines was individually analyzed, documenting the tasks performed by workers on the machine and the energies involved in those tasks, as well as the implementation of the needed changes and improvements. Once the needed information was gathered, a safety procedure was developed and implemented for each machine, showcasing the documented tasks, along with the energies that need to be blocked, and a guide was created on how to perform each task safely. The implemented changes and safety procedure seemed not to slow down the duration of the tasks and were able to reduce the injury rates seen on the machine. However, due to the time constraints placed on this work and the large timescale needed to correctly evaluate rates of injury, it is suggested to collect more data after the implementation of the safety procedures for a more robust conclusion.
