    • – Create no additional hazards
    • – Have a distinctive design or appearance
    • – Are the only devices used for controlling energy
    • – Are not used for any other purpose
    • – Are durable enough to withstand the environment they’re used in for the maximum time they’re expected to be used

    • – Do Not Energize
    • – Do Not Operate.

You must

  • Make sure tagout devices are strong enough to prevent unintentional or accidental removal.
  • Make sure the means used to attach the tag to the energy-isolating device meets all of the following:
    • – Isn't reusable
    • – Is self-locking
    • – Can be attached by hand
    • – Can't be released with a force of less than 50 pounds
    • – Is similar in design and basic characteristics to a one-piece, all-environment-tolerant, nylon cable tie.
