**Authorized Worker Requirements**

1.  The PNWD Lockout/Tagout Program is a lockout program. For the
    benefit of this program, the term "lockout" is defined to include
    the applied lock and associated *Danger- Do Not Operate or Danger*
    tag.

2.  If the requirements of this program cannot be met, a job-specific
    local plan must be written. The plan must be approved by the PNWD
    Lockout/Tagout Committee and the Controlling Organization, and
    communicated to the authorized workers prior to performing work.

3.  Each authorized worker installs and removes only their locks and
    Danger tags (form \# 54-6001-955) on the isolation device(s) for
    their own safety in accordance with this lockout program.

4.  No one may authorize another person to ignore or violate this
    program.

5.  No one may operate any device on which a lockout is installed.

6.  No authorized worker may remove their lockout if doing so creates an
    unsafe condition.

7.  No authorized worker may install a lockout on any system without the
    approval of the Controlling Organization **except** in an emergency
    situation. This is to make sure that the Controlling Organization
    knows the status of its equipment/systems.

8.  The authorized worker performs the safe-to-work check before
    performing service and maintenance or if the authorized worker
    believes the configuration has changed, to verify that hazardous
    energy and materials are adequately controlled for their personal
    protection. Where an authorized worker is not qualified to perform
    the necessary inspection or test, he may witness it being performed
    by an authorized worker who is qualified. Where work is performed
    inside a radiation area, confined space, flash protection boundary,
    or similar hazardous environments, an authorized worker(s) may
    perform the safe-to-work check (witnessed or not) on behalf of
    others with their consent. Consent must be documented in the JPP or
    written lockout/tagout instructions.

9.  Only keyed locks are authorized for lockout.

10. The locks used for lockout must be green in color and green locks
    must not be used for any other purpose.

11. The key to authorized worker assigned locks must remain under the
    control of the authorized worker.

12. Authorized workers making lockout/tagout decisions must have an
    understanding of the operation and configuration of the equipment to
    fully identify and evaluate its hazards.

13. If an isolating device can be locked out, it must be locked out. If
    the isolating device cannot be physically locked out, it must be
    tagged out in full compliance with all provisions of the OSHA
    standard while meeting the following requirements:

-   Protection equivalent to that provided by a lock must be established
    with a *Danger and/or Danger-Do Not Operate* tag.

> **Note:** Examples of measures that could be used to provide
> protection equivalent to locks and prevent a system from being
> energized include removing an isolating circuit element or fuse,
> opening extra circuit disconnects, physical blocking of mechanical
> systems, or removing valve handles.

-   The tagout devices, including their means of attachment, must be
    durable and substantial enough to prevent inadvertent or accidental
    removal. If possible, the lock should be placed through the grommet
    on the tag. Otherwise, use of an environmentally-tolerant nylon
    cable tie or equivalent having a minimum unlocking strength of not
    less than 50 pounds (22.7 kg) is recommended as the means of tagout
    attachment.

> **Note:** If at all reasonable, the machine or equipment should be
> modified to accept a lockout device at the energy isolating point as
> soon as possible. Also, whenever new machines or equipment are
> installed, energy isolating devices for such equipment must be
> designed to accept a lockout device.

14. Equipment with attached lockouts or tagouts are not to be removed
    from their installed location.

15. Hazardous energy/material control boundaries established by
    Controlling Organization lockout/tagout (*Danger-Do Not Operate*
    tags) must be locked out by the authorized worker while performing
    service and maintenance.
