Use of Portable Generators
Some people use emergency generators to provide back-up power. While generators can be used in a safe manner, improper use of a generator can pose significant hazards to you and your family. Hazards include electric shock, carbon monoxide poisoning, explosion and fire. [..] You cannot see, smell or taste carbon monoxide (CO), but at high levels it can kill a person within minutes. Carbon monoxide is produced whenever any fuel such as gas, oil, kerosene, wood, or charcoal is burned. Know the symptoms of CO poisoning. At moderate levels you or your family can get severe headaches, become dizzy, mentally confused, nauseated, or faint. Low levels can cause shortness of breath, mild nausea, and mild headaches. Since many of these symptoms are similar to those of the flu, food poisoning, or other illnesses, you may not think that CO poisoning could be the cause. Never operate a generator in an enclosed place including your garage or near an open door or window. Source 6
