“LOTO” typically stands for “Lockout-Tagout.” It’s a safety procedure used in industry and research settings to ensure that dangerous machines are properly shut off and not started up again unexpectedly. The process involves isolating energy sources (such as electrical, mechanical, hydraulic, or pneumatic) and locking or tagging them in the off position to prevent accidental activation while maintenance or servicing work is being performed. This helps prevent accidents and injuries caused by unexpected machine start-ups.
