Dig Carefully on Your Work Site

Call before you dig

OHS Code states you are responsible

The Alberta Occupational Health and Safety Code says you must call Alberta One-Call to mark underground utilities in your work area.

Alberta One-Call: 1-800-242-3447

You must call before you begin work

  • It is a free service (although for privately installed utilities, there may be a fee).
  • Markings are valid for 30 days.
  • Call at least two working days ahead.
  • Give more notice during long weekends and holidays.

You can face big costs for hitting a line

  • Seriously hurting yourself or another worker.
  • Causing a fatality.
  • Losing work time.
  • Paying expensive repair costs.
  • Causing a loss of natural gas service.

Digging Safety - Know What's Below

Natural gas markings are yellow

They show:

  • The direction the natural gas line runs.
  • The approximate location of the line.

 

They do not show:

  • The depth of the line – which can be just a few inches from the surface as soil is graded or erodes.

 

Keep a one metre clearance

Natural gas lines stand no chance against excavation equipment. They will be punctured easily.

  • Keep a one metre (three feet) safety clearance on either side of the outside of the locate marks.
  • This is the hand expose zone – absolutely no machines.
  • If you are excavating in this zone, you must use a shovel or hydrovac to carefully expose the natural gas line.
  • You must be able to see the line – to verify its location – before continuing the job.
