The external surfaces of the generator may become quite hot, so you need to keep your children away from the unit when it is running. Additionally, generators pose three common hazards:
-Carbon monoxide fumes
-Electrical shock
-Fire
Internal combustion engines give off carbon dioxide as a byproduct of fuel consumption. This gas is both odorless and colorless, so you cannot know that you are breathing the fumes. For this reason, generators should never be run indoors, or in confined spaces. If you should begin to feel light-headed, dizzy or nauseous while your generator is running, get to fresh air immediately. Install a CO alarm to check for deadly carbon monoxide levels, and change the battery frequently, whenever you adjust your clocks for daylight savings time.
To prevent shock, make sure your generator stays dry. Do not touch it with wet hands or when you are standing in a puddle. Make sure your unit is properly grounded. Don't overload the generator and make sure that if you are using extension cords, they are rated for the load they will be supporting. NEVER plug your generator into your house's wall outlets. Doing so will create backfeed in the electric lines, possibly causing electrocution of unsuspecting utility workers who are trying to place your home back in service.
Finally, because you are running a motor fueled by a flammable substance, you must take care to avoid fires. Store the gasoline away from the generator in properly labeled non-glass containers. Gas vapors can run along the floor and ignite from the heat of the generator. Always turn off the generator and allow it to cool prior to refilling the gas tank to protect against spilled gas ignition. Do not smoke or allow open flames near your generator.
