Importance of Lock Out Tag Out in industrial workplaces?
Short answer: Lockout/tagout (LOTO) is a procedure that controls hazardous energy during maintenance, repair or cleaning. Workers identify every energy source, shut down and isolate the equipment, apply their own locks and tags, release stored energy, then verify it can't start before work begins. It prevents unexpected start-up, one of the most serious machine hazards.
Keyline Safety's stand
Lockout is personal. Every worker who could be hurt should put on their own lock, and nobody starts work until someone has tried to start the machine and proven it's dead. A tag alone is a warning, not an energy control.

Frequently asked questions
What is the difference between lockout and tagout?
Lockout physically stops an energy-isolating device from being operated, using a lock. Tagout adds a warning tag that identifies who applied the lock and why. A tag on its own doesn't stop a machine from starting.
What are the basic steps of lockout/tagout?
Prepare and identify all energy sources, notify affected workers, shut down, isolate each source, apply personal locks and tags, release or block stored energy, verify the equipment can't start, and reverse the steps carefully when work is done.
Does each worker need their own lock?
Good practice is that every worker exposed to the hazard applies their own lock. Group lockout boxes let several workers lock out the same equipment with their own locks.
Is lockout the same as hazardous energy control?
No. CCOHS explains that lockout is one method of hazardous energy control. Where lockout alone can't reach a zero-energy state, other controls such as blocking are used.
