An emergency shutoff switch for the furnace is found inside the furnace room beside the unit. Why is placement reported?

The emergency shutoff exists for the case where something is already wrong with the furnace — a fuel smell, smoke, an unusual noise, visible flame outside the burner compartment. Its whole value lies in being reachable at that moment, which means being reachable without approaching the equipment that is malfunctioning. A switch mounted beside the unit inside the furnace room fails that test: to shut the furnace down you must walk toward the hazard and into a room that may be filling with smoke or gas. That is why the recognized placement is at the entrance to the space, outside the room where practical, and clearly labelled. The inspector reports the placement as a safety concern and recommends relocation; the switch working correctly does not change the finding, because the defect is where it is rather than what it does.

An emergency shutoff must be reachable without approaching the malfunctioning appliance. Placed beside the unit inside the furnace room, using it requires entering a space that may already be hazardous, which defeats its purpose.

Heating appliances are provided with an emergency shutoff, located so it can be operated without entering the immediate vicinity of the appliance, typically at the entrance to the equipment room, and identified with a label. Inspectors report both placement and labelling deficiencies.

Shut It Off From the Doorway. If you have to walk toward the fire to turn it off, the switch is in the wrong place.

Check for the label as well as the location. An unlabelled switch that nobody can identify in an emergency is a separate and equally reportable deficiency.
