Text For Citation: 01 Item/Group: 002B Hazard:

1910.333(b)(2)(iv)(B) A qualified person shall use test equipment to test the circuit elements and electrical parts of equipment to which employees will be exposed and shall verify that the circuit elements and equipment parts are deenergized. The test shall also determine if any energized condition exists as a result of inadvertently induced voltage or unrelated voltage backfeed even though specific parts of the circuit have been deenergized and presumed to be safe. If the circuit to be tested is over 600 volts, nominal, the test equipment shall be checked for proper operation immediately after this test. 29 CFR 1910.269(m)(3)(vi): After the applicable requirements in paragraphs (m)(3)(i) through (m)(3)(v) of this section have been followed and the system operator gives a clearance to the employee in charge, the employer shall ensure that the lines and equipment are deenergized by testing the lines and equipment to be worked with a device designed to detect voltage. (a) On or about December 7, 2024, and days prior, at the generator/ transformer and the lines used to transmit electrical energy from the generator to equipment in the "Sound Room" test area, the employer did not require and ensure verification of de-energization of the circuit by testing the circuit with electrical test equipment. This exposed employees to electrical hazards.
