Colors of Lockout Locks and Tags
Though OSHA has not yet provided a standardized color coding system for lockout locks and tags, typical color codes are:
Red tag = Personal Danger Tag (PDT)
Orange tag = group isolation or lockbox tag
Yellow tag = Out of Service Tag (OOS)
Blue tag = commissioning and test tag
Red lock = used by an authorized employee to lockout equipment during servicing
Orange lock = used by a group isolator to indicate that servicing is safe to perform
Yellow lock = used by an affected employee to lockout equipment before servicing
Blue lock = used instead of an orange lock for lockboxes with more than 6
isolation points
