Click on bconecall.ca or call BC One Call at1-800-474-6886 or *6886 on the TELUS or Rogersmobile network to request all gas line locationrecords. This is a requirement of FortisBC andprovincial gas safety regulations. You should receivethis information in about two business days.2. Have gas line information on site duringthe excavation. If you need help understandingthis information, call our Public UndergroundLocation Services at 1-888-822-6555.You could damage much morethan a gas lineExcavating is serious business. That’s why it’s criticalto take due care.Knowing where natural gas lines are located beforeyou start excavating is the first step to ensure safetyon the job. Do this by calling or clicking BC One Callto request free underground gas line information.Once you’ve received maps, you must ensure a safework site by hand digging to expose the gas linebefore using mechanical equipment.Hitting a line not only threatens the safety of thepublic and your workers, but can also impact theenvironment and cost you money. So take thenecessary precautions, play it safe and call or clickbefore you dig.BC One CallClick: online requests: bconecall.caToll free: 1-800-474-6886Cell: *6886 (on TELUS or Rogers mobility networks)3. Use the gas line information to locate and marklines with paint or stakes and maintain themuntil digging is underway.4. Hand dig first to expose gas lines before usingmechanical equipment.23
Your responsibilitiesWhether you’re digging up a major intersection orinstalling fence posts, B.C. regulations require youto take three steps before you start digging:1. Click or call BC One Call and request line locationinformation. The call is free.2. Use the information provided to mark the locationof buried gas lines.3. Hand dig to expose the gas line.You may: use an electronic pipe locator to confirm theapproximate location of the gas line use mechanical equipment only to remove surfacecover. You must hand expose the gas line withinthe no mechanical dig zone in a sufficient numberof locations to determine the exact positions anddepths of the installation before further use ofmechanical excavation equipment. (see FIG. 1) use hydrovac excavation equipment withinthe boundary limitGuidelines for locatingand hand diggingBefore beginning any excavation or boring, you mustlocate the buried gas line and hand dig to exposethe line. Technical Safety BC has approved theseguidelines for locating and hand digging.You must: have gas line information on site identify the location of the gas line and markthe line with paint or stakes until diggingis underway hand dig to expose the gas line if your excavation iswithin 1 m either side of the indicated location ofthe gas line.Sluff dirt into hole foreasy removal by excavator1m1mNo mechanized dig zoneFIG. 1 - Hand digging for a gas line45
Do not use mechanical equipment withinthe no mechanized dig zone until the gasline has been hand exposed.When exposing buried gas lines, the “no mechanizeddig zone” refers to the area equal to the diameter of thegas pipe, plus one metre on either side of the gas line’sindicated location extending upwards to the surface.Hand dig within “the zone” to expose the pipe usingmanual equipment and tools. Mechanized equipmentshould only be used to break the surface.Safety laws and regulationsWorkSafeBC and Technical Safety BC require you toobtain buried gas line location information and handdig to expose the lines.For specific information about regulations that governexcavating or working near pipelines in B.C., contact:Technical Safety BCSafety Standards Act and Gas Safety al Health and Safety Regulationworksafebc.comBC Oil and Gas CommissionOil and Gas Activities Act and Regulationsbcogc.ca6Line location assistanceYou are responsible for contacting BC One Call andrequesting line location information.
