Any size flame can spark an explosion. Before turning the gas back on, have the gas system checked by a professional. Use a generator or other fuel-powered machines outside the home. CO fumes are odorless and can quickly overwhelm you indoors. Use the appropriate sized and type power cords to carry the electric load.
Overloaded cords can overheat and cause fires.
Never run cords under rugs or carpets where heat might build up or damage to a cord may go unnoticed. Never connect generators to another power source such as power lines. The reverse flow of electricity or backfeed can electrocute an unsuspecting utility worker. Do not use the kitchen oven range to heat your home. In addition to being a fire hazard, it can be a source of toxic fumes.
