Severe storms, whether during the winter or summer, can cause a loss of power that can last for hours or days. Using a generator is one way to help provide basic electric service to maintain a reasonable level of safety and security and possibly minimize the loss of food stored in a refrigerator or freezer. Most homeowners using generators will opt for the less expensive portable type. Portable generators, which are typically powered by gasoline, can effectively provide a limited power supply.  

When using a generator, it is critical to ensure it has been installed properly and is operated in a safe manner. There have been many incidents where individuals have survived a storm only to suffer deadly consequences due to an improperly installed or maintained generator. And the danger also extends to utility crews helping to restore power.

The danger to utility workers primarily comes from feedback, or a surge of electricity from the generator that travels through the house wiring and back into the power lines.  Anyone working on those lines could be electrocuted. So could individuals making contact with downed lines that hadn’t been properly terminated or secured.

To prevent this, before using a generator, the wiring in the house must be disconnected from the incoming power lines using a transfer switch.  This disconnection from the incoming power is also needed to protect the generator from damage when the power returns. Using the main disconnect in place of a transfer switch does not protect against all feedback situations.

For the efficient and safe use of a portable generator heed these recommendations:

• Store the unit where it is readily available in an emergency.
• Store fuel only in approved containers in a safe manner.
• Follow all manufacturer instructions.
• Have an electrician install a transfer switch to disconnect house wiring from the power company supply. 
• Never connect a generator directly to a wall outlet; it should only be directly connected to appliances or other electric equipment.
• Only operate gasoline-fired units outdoors.  Never run them in a closed-in area – not even for a short time. The exhaust from the unit can contain deadly carbon monoxide
