A safety feature of gas furnaces is control shutoffs to prevent gas leaks.  However, although it doesn’t happen often, gas leaks do happen. If you smell gas in your Edmonton home, immediately leave your home, leaving the door open.  Once safely out of your home, immediately call the gas company or fire department.  Only re-enter your home when the gas company or fire department says it’s safe.

When leaving your home, do not turn any lights on or off, and do not try to shut off the gas leading to the furnace.
