Lockout is the placement of a lockout device on an energy isolating device ensuring that the energy isolating device and the equipment being controlled cannot be operated until the lockout device is removed.
A lockout device is a device that utilizes a positive means, such as a keyed lock, to hold an energy-isolating device in the safe position and prevents the energizing of a machine or equipment. Included are blank flanges and bolted slip blinds.
Tagout is the placement of a tagout device on an energy-isolating component to indicate that the energy isolating device and the equipment being controlled may not be operated until the tagout device is removed.
A tagout device is a prominent warning device, such as a tag and a means of attachment, which can be securely fastened to an energy-isolating device to indicate that the energy isolating device and the equipment being controlled may not be operated until the tagout device is removed. Tag attachment devices must be of a non-reusable type, attachable by hand, self-locking and non-releasable with a minimum unlocking strength of 50 pounds.
