What should you avoid doing during a gas furnace emergency?

In a gas furnace emergency, it is crucial to avoid using any electrical switches. This is because electrical sparks from switches may ignite gas that has accumulated in the area, exacerbating the dangerous situation. If there is a gas leak or the possibility of an explosion, any electrical device could act as an ignition source. Safety protocols recommend maintaining a safe environment and turning off gas supply lines if it is safe to do so, but using electrical equipment poses unnecessary risks.

Other actions may be appropriate in certain emergency situations; for example, evacuating other occupants and calling for assistance are generally needed for safety. Leaving the area while waiting for help might also be considered a necessary precaution in some contexts. However, manipulating electrical devices should be avoided to prevent further danger.
