Self-Inspection Checklist

Guidelines: This checklist covers the regulations issued by the U.S. Department of Labor, Occupational Safety and Health Administration (OSHA) under the general industry standards 29 CFR 1910.331, 1910.332, and 1910.333. This checklist applies to persons who are at risk of electrical shock. It does not apply to qualified persons working on generation, transmission, and distribution installations; communications installations; installations in vehicles; and railway installations. Definitions of terms in bold type are provided at the end of the checklist. Please review the Control of Hazardous Energy Sources checklist with this checklist. The regulations cited apply only to private employers and their employees, unless adopted by a State agency and applied to other groups such as public employees. A yes answer to a question indicates that this portion of the inspection complies with the OSHA and EPA standard, or with a non-regulatory recommendation.

This checklist does not address work on or near energized overhead lines or work in confined or enclosed work spaces with energized lines. For these conditions, please consult 29 CFR 1910.333(c)(3) and 1910.333(c)(5) respectively.

    2. direct contact with energized parts and against
    indirect contact through a conductive object?
    [29 CFR 1910.333(a)(2)]
 Y   N   N/A   ?? 
Working On Or Near Exposed Deenergized Parts

    2. A qualified person verifies that the circuit

      3. elements and electric parts of equipment to
      which students or employees will be exposed
      are deenergized. The qualified person must
      also determine whether any energized
      conditions exist as a result of inadvertently
      induced voltage or unrelated voltage feedback
      (even though parts of the circuit have been
      deenergized and presumed to be safe).
 Y   N   N/A   ??

      4. person who applied it or under his or
      her direct supervision. However, if the
      person who applied the lock or tag is
      absent from the workplace, the lock or
      tag may be removed by a qualified
      person designated to perform this task
      provided that:
       
      1. The person who applied the lock or tag

        2. is not available at the school.
         
      2. The person who applied the lock or tag

        3. is aware that the lock or tag has been

Definitions:
 
Qualified person: one who is familiar with the construction and operation of the equipment and the hazards involved. A person is likely to be considered "qualified" with regard to certain equipment in the workplace, but "unqualified" as to other equipment. A person who is undergoing on-the-job training and who, in the course of such training, has demonstrated an ability to perform duties safely at his or her level of training and who is under the direct supervision of a qualified person is considered to be a qualified person for those duties.
