WAC 296-803-40005
Provide appropriate means to control energy

You must

  • Provide the means necessary to isolate, secure, or block machines and equipment from energy sources.

Note

Note:

  • Examples of means to control energy include:
    • – Locks
    • – Tags
    • – Chains
    • – Wedges
    • – Key blocks
    • – Adapter pins
    • – Self-locking fasteners
    • – Blind flanges
    • – Cribbing.

WAC 296-803-40010
Make sure lockout and tagout devices meet these requirements

You must

  • Make sure lockout and tagout devices meet all of the following:
    • – 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
    • – Are standardized within the facility by color, shape, or size
    • – Identify the person applying the device.

WAC 296-803-40015
Make sure lockout devices meet these additional requirements

You must

  • Make sure lockout devices are strong enough so that removing them by other than the normal unlocking method requires:
    • – Excessive force
      or
    • – Unusual techniques, such as the use of bolt cutters or other metal-cutting tools.

WAC 296-803-40020
Make sure tagout devices meet these additional requirements

You must

  • Make sure all tags:
    • – Use the same print and format within a facility
    • – Are constructed and printed so they won't deteriorate and the message on the tag remains legible when:
        • Exposed to weather
        • Used in wet or damp locations
        • Used in corrosive environments such as areas where acid or alkali chemicals are handled or stored.
      – Have a warning about not energizing the machine or equipment.

Note

Note:

  • The warning on the tag should include wording such as:
    • – Do Not Start
    • – Do Not Open
    • – Do Not Close
    • – 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.
