Canadian Electrical Code Part 1
CSA C22.1 No.1 – Section 60 - Communications Systems
Canadian Electrical Code Part III
CSA C22. 3 No.1-06 – Overhead Systems
CSA C22.3 No. 7-06 – Underground Systems
TELUS Access (Outside Plant) Engineering Standards
TELUS Outside Plant Practices (TOPPS)
4. Slide 4 Engineering and Design CSA C22.3 No. 1- Overhead Systems and CSA C22.3 No. 7 – Underground System
Provides minimum design requirements for construction of Overhead and Underground Facilities that are most important from the points of view of
(a) safety to persons;
(b) continuity of service; and
(c) protection of property.
5. Slide 5 Engineering and Design CSA C22.3 No. 1 – Overhead Systems
Minimum CSA Vertical Separation for messenger is 1.0 m (40”) below a Power Utility Secondary Rack
If there is no Secondary Rack, the Minimum CSA Vertical Separation for messenger is 1.0 m (40”) below the Power Utility Neutral
6. Slide 6 Engineering and Design CSA C22.3 No. 1 – Overhead Systems
Clearances and Separation at Mid-span (up to 75 meters span)
7. Slide 7 Engineering and Design CSA C22.3 No. 7 – Underground Systems
Minimum separation of 300mm (1 ft) between gas and supply and communication cables
Example Showing Location of Various Services
8. Slide 8 Engineering and Design CSA C22.3 No. 7 – Underground Systems
In January 1, 1996, the CSA Standard was revised
Direct Buried Ducts shall be color coded as follows:
Supply Lines RED
Communication Lines ORANGE
To date, Red is not the standard color used by Electric Utility Companies
TELUS is currently using the Orange Duct
CAUTION: Although the Standard was adopted in 1996, always verify with proper utilities before excavating

10. Slide 10 Construction and Power Awareness Construction and Power Awareness
There are three things to consider when dealing with Construction and Power Awareness:
Limit of Approach – Canada Labor Code Standards
Safe Work Space – TELUS Corporate Standards around Limit of Approach
Joint Use Placing Standards (with the local power authority)
As a Federally regulated company, TELUS is required to follow Part II of the Canada Labour Code which references the Canadian Electrical Code Part III
11. Slide 11 Limit of Approach to Power Conductors Under the Canada Labour Code the following Limit of Approach (LoA) applies for a “qualified person”
An employee or any thing that an employee uses, touches or handles cannot be closer to any live electrical equipment than the Limit of Approach for the voltage specified in the Code
LoA Power Utility Primary = 1.2 m (4’-0”) e.g. 12 kV – 22 kV to ground
A “qualified person” means, in respect of a specified duty, a person who, because of his knowledge, training and experience, is qualified to perform that duty safely and properly
TELUS employees are not qualified Power Line Technicians or electricians, we are qualified telecommunications technicians and are able to work on the joint use plant under these Regulations
12. Slide 12 Safe Working Space
The purpose of the Safe Working Space is to ensure an employee never violates the Limit of Approach
The Safe Working Space (Safety Factor) is = 0.9 m (3’-0”) for Power Utility Primary Power (14.4/25 kV)
13. Slide 13 Placing Distance – Vertical Construction Minimum CSA Placing Distance for Messenger = 1.0 m (40”) from Local Power Utility Plant

Voltage Detector
Rubber Gloves
Class 1 Rubber Gloves
Class 2 Rubber Gloves
16. Slide 16 Safety Equipment Voltage Detector is used for testing:
17. Slide 17 Safety Equipment Rubber Gloves
Class 1 Rubber Gloves – rated up to 7,500 Volts
To protect the employee against limited high voltages
When working on wires that cross over power or trolley circuits
Class 2 Rubber Gloves – Rated up to 17,000 Volts
When working on earth return systems in Alberta
When working on Delta systems in BC such as in Mines
18. Slide 18 Safety Training Safety Training

20. Slide 20 Conclusion – Safety in the Outside Plant Safety when working around power is everyone’s business
Understand how to identify hazards
Know your Limits of Approach
Understand Safe Working Space / Safety Factor
Use the supplied Personal Protective Equipment
The most important person in your Personal Safety Program is…
