Accepted Answer

Lockout/tagout (LOTO) is a safety procedure that prevents machines and equipment from accidentally starting up during maintenance or repair. It's also known as Control of Hazardous Energy. 
LOTO protects workers from: serious injuries or fatalities, unexpected energization, release of stored energy, and exposure to hazardous substances.

To implement LOTO in a factory, you can follow these steps: 
Prepare: Notify relevant employees
Shutdown: Shut down the equipment
Isolate: Isolate the equipment from the hazardous energy source
Lockout/tagout: Attach locks and tags to the control devices
Check stored energy: Release or block any stored energy
Verify: Verify the lockout
Perform work: Perform scheduled servicing
Restore: Restore the equipment to service
