The LOTO process is a safety procedure mandated by organizations like OSHA (Occupational Safety and Health Administration) to control hazardous energy sources, such as electrical, mechanical, hydraulic, or pneumatic energy. The process involves isolating energy sources, locking and tagging them to prevent accidental startup, and ensuring that equipment remains in a safe state during maintenance. A lockout device (typically a padlock) secures the energy isolation point, while a tagout device provides a visible warning to others not to restore energy.
