Lock-Out Tags - Hints for Effective Designs

Your lock-out tag shouldn't be a wallflower! Use solid background or stripes to get attention. Many prefer the ANSI tag designs which show the signal alert header.

Use direct instructions. With a bold symbol and a "DO NOT OPERATE" message, you remove any ambiguity from your message. A symbol provides the fastest way to reinforce your message and broaden your audience.

Larger tags get attention. They are easier to fill out and to read. Follow ANSI guidelines by using proper language:. instead of printing 'Signed By', use 'Name'. Use the tag line "This Lock/Tag may only be removed by:" for more accurate records. The word 'tag' or 'lock' can be circled or crossed out. This helps reinforce the strict language of §1910.147.

Printing instructions on the back of the tag ensures proper use. Always make sure that these instructions correspond with the message on the front.

See OSHA §1910.147 Lock-Out/ Tag-Out, §1910.269 for the electrical industry and §1910.268 for Telecommunications. Any effective LOTO program is built on employee buy-in, lock-out devices and training. Overcome apathy with relevant case histories changing support materials. See LOTO: Beyond the Written Procedure.

Tags should never tear off easily or embrittle with age. The tag fastener needs to have “a minimum unlocking strength of no less than 50 pounds” so that your heavy-duty tag isn't compromised [1910.147(c)(5)(ii)(C)(1)]. Use a sturdy nylon or wire tie to secure your tag on your equipment.
