Suspected natural-gas leak

If you smell natural gas or suspect a leak, leave the affected area immediately and keep others away. Do not use electrical switches, phones, appliances, flames or vehicles near the suspected leak. Do not try to ventilate the building or operate the gas meter.

From a safe location, call Liberty at 1-800-994-2762 and choose option 1, or 911. Give the exact location. For an outside leak, stay clear of the area.

Read Liberty’s natural-gas safety instructions. Ordinary appliance faults can be discussed with Matrix Mechanical after any immediate danger has been addressed.

Gas work starts with clear information about the appliance, connected load, venting, controls, and existing piping. Matrix Mechanical services residential and commercial natural gas and propane systems in Saint John and across southern New Brunswick.
