|OSHA requirements are set by statute,
standards and regulations. Our interpretation letters explain
these requirements and how they apply to particular
circumstances, but they cannot create additional employer
obligations. This letter constitutes OSHA's interpretation of
the requirements discussed. Note that our enforcement guidance
may be affected by changes to OSHA rules. Also, from time to time
we update our guidance in response to new information. To keep
apprised of such developments, you can consult OSHA's website

||Guidance on "Approval" Requirements for Generic Circuit Breaker Panel Switch Lockouts in the General Industry|
This memo is a revision to and supersedes the
June 28, 2000 memo requesting Guidance on "Approval"
Requirements for Flexible Corrugated Plastic Covers and Generic
Circuit Breaker Panel Switch Lockouts. The word
"...servicing..." located in the second sentence of
the abovementioned memo was replaced with the word, "...securing..." to accurately reflect the standard.
Generic Circuit Breaker Panel Switch Lockouts
The generic circuit breaker panel switch lockouts you described
are considered to be protective materials and hardware as
outlined in 29 CFR 1910.147(c)(5)(i), Protective materials and
hardware. Such protective materials used for lockout/tagout
consist of locks, tags, chains, wedges, key blocks, adapter pins,
self-locking fasteners, or other hardware.
The employer must provide these protective materials and
hardware for isolating, securing or blocking of machines or
equipment from their energy sources. Equipment accessories for
lockout/tagout must meet the specifications described in
1910.147(c)(5)(i) - 1910.147(c)(5)(iii). In particular, if as stated in your
letter, the generic switch lockouts can [easily] fall off, then
such protective materials and/or hardware do not fulfill the
requirements of 1910.147(c)(5)(ii)(C)(1).
I hope you find this information useful. If you have any
questions, please feel free to contact [Office of General
Industry Enforcement] at (202) 693-1850.
