Power outages can happen at any time. Backup power can be a part of any preparedness plan.

As wonderful as portable generators during storms when power is knocked out for extended periods of time, it can also be a life safety problem. Each year, many people are killed or injured by carbon monoxide due to improper placement and use of portable generators. People often purchase generators without knowing the associated risks and end up using them improperly or wiring them incorrectly. Combined, these requirements help ensure the safety of those using the generators as well as those located in the building in which the generator is providing power.

Please follow some of these safety tips to help ensure your safety while using generators:

• Portable generators must never be run or fueled indoors (or on balconies or on roofs) unless the room has the proper fire protection and ventilation required in the building code.
• Fueling from a container is permitted only when the engine is shut down and the engine surface temperature is below the auto ignition temperature of the fuel.
• The exhaust of the generator must be directed at least five feet in any direction away from any openings or air intakes and also away from the building.
• Wiring should never be directly tied into the distribution panel, where it could potentially feed back into the electrical distribution system, endangering electrical company workers who are restoring power. A properly installed transfer switch should be provided.
