Sponsored Content: What are your obligations as an excavator?

Accidentally hitting a natural gas line during an excavation is very dangerous and completely preventable. Here’s how to avoid serious risks and stay safe.

Unsafe digging is more common than you may think. On average, seven natural gas lines are damaged every day in Ontario as a result of not following safe digging guidelines.

“There have been incidents and close calls on jobsites, unfortunately,” says Nectar Tampacopoulos, manager, linear operations, Region of Peel. “There have been incidents when, even once a utility was exposed, the excavator wasn’t using safe practices — they were using a high hoe instead of hand digging around the line — and they’ve actually hit the live utility at times.”

For every construction project, it’s your responsibility to request a locate from Ontario One Call before you dig — it’s free and it’s the law. Once you have locates in hand, it’s important to follow safe digging practices around all utility lines and pipes to avoid an unsafe situation.

What are the consequences?

Let’s take a closer look at the consequences of damaging a natural gas line:

Seriously hurting yourself or coworkers.
Incurring expensive legal and repair costs, serious penalties and charges.
Losing productivity by bringing your project to a stop.
Jeopardizing future contracts and your reputation.
Interrupting natural gas service to the neighbourhood.

INCIDENT SNAPSHOT

“On February of 2013 there was a line strike to an eight-inch steel high-pressure main on Highway 7 and Woodbine in Markham. We closed down Highway 7 for a number of hours, tied up emergency personnel during that time, air traffic was also shut down until we could make it safe and make our repair.”

Top tips for a safe excavation

Have your locate information onsite
Your locator will provide you with a physical or digital locate sheet that shows the work area. They’ll also mark the area with flags and/or paint to identify the location of underground utilities. Check that your locate sheet matches the flags/paint markings on the ground before starting any work.
Keep a safe clearance from locates
Keep a one-metre safety clearance on either side of your locate marks. This is known as the “tolerance zone.”
Always dig around a natural gas line by hand first
If you’re digging in the tolerance zone, you must use a shovel or hydrovac to carefully expose the natural gas line before digging with heavy equipment.
Support the natural gas line
Install a temporary steel or wood support system to prevent the natural gas line from bending or sagging during excavation.
Shore up appropriately
For deep trenches, place boards or other bracing against the excavation walls to prevent the trench from collapsing and damaging lines.

Questions about your locate?

If you have any doubts about your locate, don’t start digging — contact the locate service provider at the number on the locate as soon as possible to get clarification.
