Most home fires start in living rooms. Second is bedrooms, third is
kitchens.

The leading cause of fatal home fire is smoking, followed by: arson,
heating equipment, electrical distribution equipment, and then children
playing with fire.

The number one cause in home fire resulting in injury, however, is
cooking equipment.

Cooking is the leading cause of home fires in the U.S. It is also the
leading cause of fire injuries. Cooking fires often result from
unattended cooking and human error, rather than mechanical failure of
stoves or ovens.

Two of every three home heating fires in the U.S. in 1998, and three of
every four related deaths, were attributed to space heating equipment.

So, let's see. Most fires start in the living room and bedroom where
you are extremely unlikely to find any natural gas equipment. The fires
that start in the 3rd most likely place, the kitchen, aren't caused by
equipment failure.

Of the fires caused by heating equipment most of the fires and even more
of the deaths are due to space heaters. I've never seen a space heater
that was run by natural gas, most of them are electric.
