Part 40 Utility Workers – Electrical

Section 799 Protective devices or equipment

Subsection 799(1) Standards

To ensure the safety of protective devices and protective equipment used by workers, employers must ensure that the devices and equipment meet the requirements of the listed standards. The devices and equipment need not be approved by an independent third-party organization such as CSA, ULC, UL, or SEI as complying with the standards. A manufacturer’s self-declaration of compliance is satisfactory.

North American manufacturers presently make products that meet the requirements of the listed standards.

ULC standards

CAN/ULC-60832-99, Insulating Poles (Insulating Sticks) and Universal Tool Attachments ((Fittings) for Live Working, is an adoption, without modification, of IEC standard 60832. The Standard specifies performance characteristics for insulating poles and accessory attachments.

CAN/ULC-D60855-00, Live Working – Insulating Foam-Filled Tubes and Solid Rods for Live Working, is an adoption, with Canadian deviations, of IEC standard 60855. The Standard applies to insulating foam-filled tubes and solid rods made of synthetic materials and intended for tools and equipment for live work on systems operating at voltages above 1 kV. Separate special technical standards give details of tests for fittings and attachments to these poles and rods, adaptable tools and complete tools.

CAN/ULC-60895-04, Live Working – Conductive Clothing for Use at Nominal Voltage Up to 800 kV A.C. and +/- 600 kV D.C., is an adoption, without modification, of IEC standard 60895. The Standard applies to conductive clothing, either assembled from component parts or forming a single complete clothing element, worn by electrically skilled persons during live work, especially bare-hand work, at a nominal power system voltage up to 800 kV a.c. and 600 kV d.c. It is applicable to conductive jackets, trousers, coveralls, gloves or mitts, hoods, shoes, overshoe socks and socks.

CAN/UCL-60900-99, Hand Tools for Live Working up to 1000 V a.c. and 1500 V d.c., is an adoption, without modification, of IEC standard 60900. The Standard applies to insulated and insulating hand tools used for working live or close to live parts at nominal voltages up to 1000 V a.c. and 1500 V d.c. Not included are tools, equipment and material supplied from an external energy source, and insulating rods and poles used for working at distances which are covered by IEC Standard 855.

CAN/ULC-60903-04, Live Working – Gloves of Insulating Materials, is an adoption, without modification, of IEC standard 60903. The Standard applies to

(a) insulating gloves and mitts which should normally be used in conjunction with leather protector gloves worn over the insulating gloves to provide mechanical protection, and
(b) insulating gloves and mitts useable without over-gloves for mechanical protection.

Unless otherwise stated in the Standard, the use of the term “glove” includes both gloves and mitts. The use of the term “insulating gloves” designates gloves providing electrical protection only. The use of the term “composite gloves” designates gloves providing electrical and mechanical protection.

CAN/ULC-D60984-00, Sleeves of Insulating Material for Live Working, is an adoption, with Canadian deviations, of IEC standard 60984. The Standard applies to insulating sleeves for the protection of workers from accidental contact with live electrical conductors, apparatus or circuits.

CAN/UCL-D61112-01, Blankets of Insulating Material for Electrical Purposes, is an adoption, with Canadian deviations, of IEC standard 61112. The Standard applies to insulating blankets for the protection of workers from accidental contact with live or earthed electrical conductors, apparatus or circuits and avoidance of short circuits on a.c. and d.c. installations.

CAN/ULC-D61229-00, Rigid Protective Covers for Live Working on a.c. Installations, is an adoption, with Canadian deviations, of IEC standard 61229. The Standard applies to rigid insulating covers for live working on a.c. installations, including those described in IEC Standard 743.

CAN/ULC-61236-99, Saddles, Pole Clamps (Stick Clamps) and Accessories for Live Working, is an adoption, without modification, of IEC standard 61236. The Standard applies to saddles and pole clamps (stick clamps) used for live working, and to their accessories. The standard specifies the dimensional and mechanical characteristics to be given by the manufacturer for each tool, the corresponding mechanical tests, and the other points to be checked (visual, functional, marking, etc.).

CSA standard

CSA Standard, CAN/CSA-C225-00, Vehicle-Mounted Aerial Devices, sets criteria for the design, manufacture, testing, inspection, installation, maintenance, use and operation of vehicle-mounted aerial devices. These devices are installed on a chassis, are primarily used to position workers for work purposes, and are used for operator training. The vehicle may be a truck, trailer or all-terrain vehicle. The design and manufacturing requirements of the Standard apply to those devices manufactured after the date of publication of the Standard.

The Standard recognizes both insulated and non-insulated aerial devices. Insulated aerial devices are classified into three categories based on the degree of electrical protection they provide and the type of work being performed.

Subsection 799(2) Effective date

No explanation required.

Subsection 799(3) Laboratories performing electrical testing

Because electrical utility workers rely on high voltage protective devices and equipment such as voltage detectors, insulating sleeves, protective covers and insulating blankets for their protection, laboratories testing this equipment must ensure that testing is performed properly. Laboratories performing this work must meet the requirements of ASTM Standard D2865-06, Standard Practice for Calibration of Standards and Equipment for Electrical Insulating Materials Testing.

Compliance with the standard requires an employer to establish and maintain calibration procedures for measuring and test equipment used for testing electrical insulating materials. This ensures the accuracy and precision of any measurements. The Standard also presents requirements applicable to the calibration of reference standards and test and measuring equipment, and personnel training.
