Process/Skill Questions:

- What does it mean when one places a lock on a device to prevent the release of energy?
- What does it mean when a tag is placed on a switch or other shutoff device warning others not to start that piece of equipment?
- Why does machinery or equipment need to be locked out while being repaired?
- Why should one never leave the key in the lock when “locking out”?
