Don't Cut Corners When It Comes to Safety
Permanent Standby Generators
Portable Generators
Portable generators are useful when temporary or remote electric power is needed, but they also can be hazardous.
The primary hazards to avoid when using generators are carbon monoxide (CO) poisoning from the toxic engine exhaust, electric shock or electrocution, and fire.
Every year, people die in incidents related to portable generators. Most of the incidents associated with portable generators reported to CPSC involve CO poisoning from generators used indoors or in partially-enclosed spaces.
Carbon Monoxide Hazards
Generators should NEVER be used in enclosed or partially-enclosed spaces. Generators can produce high levels of CO very quickly. When you use portable generators, remember that you cannot smell or see CO. Even if you can’t smell exhaust fumes, you may still be exposed to CO.
If you start to feel sick, dizzy, or weak while using generators, get to fresh air RIGHT AWAY. DO NOT DELAY. The CO from generators can rapidly lead to full incapacitation and death.
If you experience serious symptoms, get medical attention immediately. Inform medical staff that CO poisoning is suspected. If you experienced symptoms while indoors, have someone call the fire department to determine when it is safe to re-enter the building.
Follow These Guidelines to Make Sure That Your Generator Is Working Safely
Some customers prepare for the possibility of power outages by buying an electric generator as a standby system to keep lights and appliances running until service is restored.
A generator may be able to save food in your refrigerator or freezer during a prolonged outage, let you keep your home office running, or power other essential equipment. Generators can be expensive and noisy. They can also pose serious safety hazards to you and to others, so please follow all safety instructions provided by the manufacturer.
The law requires that customers with a permanently installed or portable generator do not connect it to another power source, such as utility company power lines. If you own and operate a generator, you are responsible for making sure that electricity from your unit cannot "backfeed," or flow into utility power lines. For safety's sake, be sure to use your generator correctly. If you don't, you risk damaging your property and endangering your life and the lives of utility line workers who may be working on power lines some distance from your home.
Follow these safety tips to protect against CO poisoning:
NEVER use generators indoors, including in homes, garages, basements, crawl spaces, and other enclosed or partially-enclosed areas, even with ventilation. Opening doors and windows or using fans will not prevent CO build-up in the home.
Follow the instructions that come with your generators. Locate your generators outdoors and away from doors, windows, and vents that could allow CO to come indoors.
Install battery-operated CO alarms or plug-in CO alarms with battery back-up in your home, according to the manufacturer’s installation instructions. The CO alarms should be certified to the requirements of the latest safety standards for CO alarms (UL 2034, IAS 6-96, or CSA 6.19.01).
Test your CO alarms frequently and replace dead batteries.
Electrical Hazards
Follow these tips to protect against shock and electrocution from generators:
Keep the generator dry and do not use in rain or wet conditions. To protect from moisture, operate it on a dry surface under an open, canopy-like structure. Dry your hands if wet before touching generators.
Plug appliances directly into generators. Or, use a heavy duty, outdoor-rated extension cord that is rated (in watts or amps) at least equal to the sum of the connected appliance loads. Check that the entire cord is free of cuts or tears and that the plug has all three prongs, especially a grounding pin.
NEVER try to power the house wiring by plugging the generator into a wall outlet, a practice known as “backfeeding.” This is an extremely dangerous practice that presents an electrocution risk to utility workers and neighbors served by the same utility transformer. It also bypasses some of the built-in household circuit protection devices.
If you must connect the generator to the house wiring to power appliances, have a qualified electrician install the appropriate equipment in accordance with local electrical codes. Or, check with your utility company to see if it can install an appropriate power transfer switch.
For power outages, permanently installed stationary generators are better suited for providing backup power to the home. Even properly connected portable generators can become overloaded. This may result in overheating or stressing the generators components, possibly leading to a generator failure.
Fire Hazards
Follow these tips to prevent fires:
Never store fuel for generators in the home. Gasoline, propane, kerosene, and other flammable liquids should be stored outside of living areas in properly-labeled, non-glass safety containers.
Do not store them near a fuel-burning appliance, such as a natural gas water heater in a garage. If the fuel is spilled or the container is not sealed properly, invisible vapors from the fuel can travel along the ground and can be ignited by the appliance’s pilot light or by arcs from electric switches in the appliance.
Before refueling the generators, turn it off and let it cool down. Gasoline spilled on hot engine parts could ignite.
Permanent Standby Generators
When a generator is permanently connected to a customer's electric system, it energizes the building's wiring. This type of installation requires a device that prevents the generator from being connected to utility power lines. Follow these safety tips:
-
Only a qualified professional, such as a licensed electric contractor, should install a permanent standby generator.
-
A double-pole, double-throw transfer switch (see diagram) is the recommended device to keep your generator from backfeeding into Utility system. The switch also keeps Utility power from re-energizing your house wiring while your generator is running, protecting your generator, wiring and appliances from damage when your service is restored.
-
Have all additions to your house wiring inspected by your city or county building department.
-
When installation is complete, call the Local Utility to let them know about your back-up system. They should make a note in their records to remind our workers of your generator if they are working on an outage in your area. In some cases, Utility line workers may ask to check your electric generator transfer switch for safety.
-
If you already have a permanently installed standby generator but you don't know if it's installed properly, call your local building inspector or a licensed contractor for help.
You are responsible for any injuries or damage to your property, your neighbors' or Utility , from an improperly installed or operated generator.
Portable Generators
Portable generators are designed to be connected only to selected appliances or lamps. These generators never should be connected directly to a building's wiring system.
-
Before starting your generator, carefully read and follow all of the manufacturer's instructions.
-
Be sure that the total electric load on your generator won't exceed the manufacturer's rating.
-
Always locate your generator where its exhaust will vent safely.
-
Prioritize your needs. Use the lowest wattage light bulbs that provide a safe level of light, reserving power for additional lighting elsewhere or a small appliance. Remember that the greater the load on your generator, the more fuel it will use.
-
Keep cords out of the way so they don't present a tripping hazard -- especially in dimly lit doorways or halls. Never run cords under rugs or carpets where heat might build up or damage to a cord may go unnoticed.
-
Extension cords must be properly sized to carry the electric load. Overloaded cords can overheat and cause fires or damage to equipment.
