LOCK RULES
1.
Use an appropriate “Lock-Out Device”, such as Lock Tongs, or a Lock Tag. Each person must
attach his or her own lock to the Lock-Out Device.
2. Identify
Locks
Each lock will be identified by a number or a name. A lock without a tag is not good enough.
Additional information that identifies the person / persons doing the work must be on the tag. Also
the type of work that is being performed should be on the tag.
3. Sign The Tag
In some instances one tag is enough, however, the tag must be signed by each worker. In some
circumstances a supervisor will also need to sign the tag.
4.
One Key Per Lock
5.
Never give your key to anyone else.
