If you plan on using an emergency generator, it’s essential that you take precautions for your safety 
and the safety of those working to restore power. The most effective way to avoid portable generator mishaps is to make sure you fully understand the proper operating procedures. Read and follow the manufacturer’s guidelines before operating or maintaining your generator – and don’t forget to use common sense.
- Generators should be used in well ventilated locations outside away from all doors, windows and vent openings.
- Never use a generator in an attached garage, even with the door open.
- Place generators so that exhaust fumes can’t enter the home through windows, doors or other openings in the building.
- Make sure to install carbon monoxide (CO) alarms in your home. Follow manufacturer’s instructions for correct placement and mounting height.
- Turn off generators and let them cool down before refueling. Never refuel a generator while it is running.
- Store fuel for the generator in a container that is intended for the purpose and is correctly labeled as such. Store the containers outside of living areas.
Safety
When plugging in appliances, make sure they are plugged directly into the generator or a heavy duty outdoor-rated extension cord. The cords should be checked for cuts, tears and that the plug has all three prongs, especially a grounding pin. If you must connect the generator to the house wiring to power appliances, have a qualified electrician install a properly rated transfer switch in accordance with the National Electrical Code® (NEC) and all applicable state and local electrical codes.
