Part 40 Utility Workers – Electrical

Explanation of Rules Referenced from the ECUC, Second Edition

Rule 4-040 Clothing

The requirements of paragraphs (1)(a) and (1)(b) do not apply – they have been superceded by section 232 of the OHS Code that reads as follows:

232(1) If a worker may be exposed to a flash fire or electrical equipment flashover, an employer must ensure that the worker wears flame resistant outerwear and uses other protective equipment appropriate to the hazard.

(2) A worker must ensure that clothing worn beneath flame resistant outerwear and against the skin is made of flame resistant fabrics or natural fibres that will not melt when exposed to heat.

Readers are referred to section 232 of the OHS Code Explanation Guide for a complete explanation of this requirement.

Paragraph (1)(c) and subsection (2) prohibit metallic articles from being in contact with the skin unless the articles are conductive clothing, eyeglasses or hearing protection acceptable for such use by the employer. These exceptions are noted because they are essential pieces of equipment that may not be available with totally non-metallic components. The prohibition on metallic articles against the skin reflects the fact that these articles can melt during an arc event and seriously injure a worker.

Paragraph (1)(d) requires workers to wear approved industrial protective headwear when working on or near energized equipment. This is a very general and non-specific requirement. Readers must follow the head protection requirements specified in sections 234 through 239 of the OHS Code that are far more detailed. Readers should refer to the OHS Code Explanation Guide for these sections to understand the headwear requirements.

Paragraph (1)(e) requires that when a worker is working on or near energized equipment, the worker must wear a long sleeved garment and the sleeves must be rolled down. This is intended to minimize the potential for electrical burns to the skin.
