Lockout-tagout (LOTO) or lock and tag is a safety procedure which is used in industry and research settings to ensure that dangerous machines are properly shut off and not able to be started up again prior to the completion of maintenance or servicing work.
Kentucky (/kÉnËtÊki/, kÉn-TUCK-ee), officially the Commonwealth of Kentucky, is a state located in the east south-central region of the United States. Kentucky is one of four U.S. states constituted as a commonwealth (the others being Virginia, Pennsylvania, and Massachusetts).
Flowing generally northwestward, the Tug and Big Sandy rivers separate Kentucky from West Virginia on the east and northeast. On the north, Kentuckyâs boundary follows the Ohio River to the Mississippi, meeting the states of Ohio, Indiana, and Illinois en route. The Mississippi River then demarcates Kentuckyâs short southwestern border with Missouri.
