LOTO, which stands for Lockout/Tagout, is a safety procedure designed to protect workers from accidental machine startup or the release of hazardous energy during maintenance or repair. The "Lockout" part involves securing the energy-isolating device with a lock, while "Tagout" uses a visible tag to warn others not to operate the equipment. Implementing LOTO ensures that all energy sources—electrical, mechanical, hydraulic, or pneumatic—are safely controlled, significantly reducing the risk of workplace injuries and creating a safer working environment.
