Lockout/Tagout (LOTO)
Lockout/Tagout (LOTO) is a safety procedure used to ensure that machinery or equipment is properly shut down, isolated from hazardous energy sources and not restarted before maintenance or servicing work is completed.
LOTO helps protect personnel from unexpected start-up, release of stored energy or exposure to dangerous conditions. In industrial environments, it is a core part of safe work planning and maintenance execution.
