Which of the following is true of an emergency generator installation?

Generators powered by internal combustion engines produce carbon monoxide (CO), an odorless, colorless, and highly toxic gas. Operating a generator in a well-ventilated area, preferably outdoors and safely away from open windows or doors, prevents the lethal buildup of this gas inside living spaces. Storing fuel directly next to the generator is a major fire hazard due to the extreme heat and potential sparks from the running engine. Additionally, for electrical safety and to protect against faults, a generator should be properly grounded rather than insulated from ground.
