Part 40 Utility Workers – Electrical

Explanation of Rules Referenced from the ECUC, Second Edition

Rule 4-218 Trimming above electrical equipment

This rule deals with the situation in which trimming cannot be safely done from below energized equipment or lines – the option presented in this rule should be used as a last resort.

Paragraph (a) requires that a tree trimming procedure, which is required by rule 4-212, be acceptable. As required by section 8 of the OHS Regulation, the procedure must be in writing and available to workers at the work site affected by the procedure. Further, the procedure must be “acceptable”, a word defined in the ECUC to mean “acceptable to the owner/operator of the utility”.

Use of this trimming approach

(a) is restricted to electrical equipment or lines operating at voltages less than 30 kilovolts between conductors,
(b) requires a fully insulated aerial device with an articulating boom,
(c) requires a utility tree trimmer to operate the aerial device (this worker is trained to perform trimming work from an aerial device),
(d) the boom is controlled by the worker in the bucket, and
(e) the aerial device if positioned and stabilized according to the manufacturer’s specifications.
