Have a licensed electrician install stationary or standby emergency generators.       
Plug appliances directly into an emergency or portable generator. This is the safest way to use a generator.
Never connect generators to your utility service through receptacles, outlets, breakers, fuses or meter boxes.
Keep children away from generators.
Never replenish fuel in a generator while it is running.
Call an electrician to repair a generator; never attempt to repair it yourself.
Operate your generator outside. Never operate it inside a building or garage
Obey all local, state and national electrical and fire codes.
Store gasoline in approved fuel containers and out of children's reach.
Have a fully charged, properly rated fire extinguisher (i.e.: rated for electrical and gas fires) ready at all times.
