Lockout/Tagout (LOTO) is a safety procedure used in workplaces to ensure that machines 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 tagging it to inform others that the machine is not to be operated. The primary goal of LOTO is to prevent accidental machine start-up, which can lead to serious injuries or fatalities. By following LOTO protocols, workers can safely perform their tasks without the risk of unexpected equipment activation.
