Safety in the Outside Plant

1. Safety in the Outside Plant TELUS Presentation Canadian CommTech Trade Show and Training Seminars Kelowna, B.C. May 13, 2009 Presented by Eddie Alfonso, P. Eng.

2. Slide 2 Safety in the Outside Plant Factors for Safety in the Outside Plant Engineering and Design Construction and Power Awareness Safety Equipment Safety Training

3. Slide 3 Engineering and Design Engineering Design CSA Standards 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

14. Slide 14 Joint Use Construction Clearances and Separation at the Joint Use Pole Similar Layout in BC Hydro and FortisBC Serving Area

15. Slide 15 Safety Equipment Safety Equipment 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 TELUS Safety Training for Employees Instructor Led Course Computer Based Training Monthly Safety Meeting with Employees

19. Slide 19 Safety Training Mandatory Safety Courses AC Power Awareness DC Power Awareness Clearances and Separations Bonding and Grounding Hazard Risk Assessment Tailgate Conferences Voltage Detectors and Rubber Gloves Electrical Protection � Station Protection, Protective Fusing Special Protection � Induction Hazards, GPR, High Voltage Interface Lockout Tagout Procedures

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�
