1910.333(b)(2)(iii) Application of Locks and Tags
JUMP TO FULL CODE CHAPTER
A lock and a tag shall be placed on each disconnecting means used to deenergize circuits and equipment on which work is to be performed, except as provided in paragraphs (b)(2)(iii)(C) and (b)(2)(iii)(E) of this section. The lock shall be attached so as to prevent persons from operating the disconnecting means unless they resort to undue force or the use of tools.
Each tag shall contain a statement prohibiting unauthorized operation of the disconnecting means and removal of the tag.
If a lock cannot be applied, or if the employer can demonstrate that tagging procedures will provide a level of safety equivalent to that obtained by the use of a lock, a tag may be used without a lock.
A tag used without a lock, as permitted by paragraph (b)(2)(iii)(C) of this section, shall be supplemented by at least one additional safety measure that provides a level of safety equivalent to that obtained by use of a lock. Examples of additional safety measures include the removal of an isolating circuit element, blocking of a controlling switch, or opening of an extra disconnecting device.
A lock may be placed without a tag only under the following conditions:
Only one circuit or piece of equipment is deenergized, and
The lockout period does not extend beyond the work shift, and
Employees exposed to the hazards associated with reenergizing the circuit or equipment are familiar with this procedure.
