Safe work planning

The Alberta Occupational Health and Safety Act, Regulation and Code outline guidelines that must be followed at worksites. Legislation requires that all work-related hazards be identified.

Employers and contractors should consult the Occupational Health and Safety Act, Regulation and Codeopens in a new tab, and follow these guidelines before working at any site.

The following is an overview on safe work planning and does not list all the requirements employers and contractors must meet to work safely.

Legislation requires that all work-related hazards be identified and that unsupervised work be performed by those workers deemed competent.

​Assess the hazards

A site visit is required to assess common work hazards such as overhead power lines, underground utilities, and scaffolding. Practice electrical safety and always consider electrical utilities to be live with the potential of causing serious injury or death.

Think safe. Work safe. Home safe.

Locates

The Alberta Occupational Health and Safety Code, the Alberta Electrical Utility Code, and the Alberta Pipeline Regulation require that a locate request be performed and the locations of all buried utilities be marked before a ground disturbance begins. Utilities and homeowners (e.g., security lighting) that are not members of Utility Safety Partners must be contacted directly for locates. All locates must be current and on site throughout the excavation.

Note: All cables must be treated as energized throughout the excavation process.

  • In the City of Edmonton, EPCOR's locate contractor will only locate primary power lines up to the primary metering point, and secondary power lines located on public property and single-family residential lots.
  • Secondary power lines located on private property in multifamily, commercial or industrial lots, as well as primary power lines located past the primary metering point, will need to be located by the facility owner or through private locates.
  • If you are working adjacent to transmission facilities (72 kV and 240 kV underground lines) your Utility Safety Partners ticket will indicate that you must first contact and receive clearance from EPCOR Transmission prior to excavation. EPCOR will locate these facilities on site or contact you to provide you with clearance after you receive your Utility Safety Partners ticket. You are not cleared to excavate until clearance from EPCOR Transmission is provided.
  • Multiple circuits can be present in the same alignment. EPCOR's locate contractor will mark separate circuits where separation exists or will indicate the presence of multiple power lines on your ticket. EPCOR power lines may be direct buried or be installed inside a conduit. In three phase areas, there are three power cables for every circuit which may be separated by up to 1 m. EPCOR can provide additional information on the number of cables.
  • If your dig site involves electrical facilites, call us at (780) 412-4500 and ask for a referral to a Safety Codes Officer. We can help with locates and provide advice on how to work safely around overhead and underground power lines.
