Abstract

A drum lockout device has a locking head with threaded plug portions for engaging either the smaller vent opening or the larger dispensing opening of a drum. When the locking head is in place, a locking key is inserted through the locking head to engage the drum end and drum flange. With a padlock securing the locking key to the locking head, the drum opening is secured against unauthorized entry.
