Gas smell near furnace
A suspected gas leak requires immediate action rather than opening panels or testing switches.
What to observe
Leave the area, avoid operating electrical switches or phones inside, and contact the gas utility/emergency service from safety.
A field example
Opening a cabinet or switching on a light may add risk when fuel is suspected. Leave the building and contact the utility or emergency service from a safe location; routine service can wait.
What the written work should say
A registered professional or utility must locate the leak and authorize safe restoration.
Where this task stops
Cleaning language is inappropriate until the hazard is resolved.
