Lockout Tagout (LOTO) is a safety procedure used in workplaces to ensure that machines and equipment are properly shut off and not able to be started up again before maintenance or servicing is completed. This process involves placing a lock on the energy-isolating device and attaching a tag that warns others not to operate the equipment. The main goal of LOTO is to protect workers from accidental machine start-up, which can lead to serious injuries or fatalities. By following LOTO protocols, employers create a safer work environment and help prevent accidents during maintenance activities.
