Definition of Lockout/Tagout
Lockout is a technique used to prevent equipment from being accidentally started and
stored energy from being released while an associated machine or piece of equipment is
being serviced.
A padlock or any other appropriate mechanical device that physically prevents the
transmission or release of energy is placed on the energy-isolating device that should be
in the off or closed position.
Energy-isolating devices can be:
• Disconnect switches
• Circuit breakers
• Valve handles
A tag also will be placed together with the locking device, to explain why the equipment
is locked, by whom and for how long.
Types of Lockout Devices:
• Disconnect switches
• Slide gates
• Valves (ball, gate, etc.)
• Blocks
• Blind flanges
