Shock and Electrocution<\/strong><\/p>\n\n\n\n The electricity created by generators has the same hazards as normal utility-supplied electricity. It also has some additional hazards because generator users often bypass the safety devices (such as circuit breakers) that are built into electrical systems. The following precautions are provided to reduce shock and electrocution hazards:<\/p>\n\n\n\n \u2022 Never attach a generator directly to the electrical system of a structure (home, office, trailer, etc.) unless a qualified electrician has properly installed the generator with a transfer switch. Attaching a generator directly to a building electrical system without a properly installed transfer switch can energize wiring systems for great distances. This creates a risk of electrocution for utility workers and others in the area.<\/p>\n\n\n\n \u2022 Always plug electrical appliances directly into the generator using the manufacturer\u2019s supplied cords or extension cords that are grounded (3-pronged). Inspect the cords to make sure they are fully intact and not damaged, cut or abraded. Never use frayed or damaged extension cords. Ensure the cords are appropriately rated in watts or amps for the intended use. Do not use underrated cords\u2014replace them with appropriately rated cords that use heavier gauge wires. Do not overload a generator; this can lead to overheating which can create a fire hazard.<\/p>\n\n\n\n \u2022 Use ground fault circuit interrupters (GFCIs), especially where electrical equipment is used in or around wet or damp locations. GFCIs shut off power when an electrical current is detected outside normal paths. GFCIs and extension cords with built-in GFCI protection can be purchased at hardware stores, do-ityourself centers, and other locations that sell electrical equipment. Regardless of GFCI use, electrical equipment used in wet and damp locations must be listed and approved for those conditions.<\/p>\n\n\n\n \u2022 Make sure a generator is properly grounded and the grounding connections are tight. Consult the manufacturer\u2019s instructions for proper grounding methods.<\/p>\n\n\n\n \u2022 Keep a generator dry; do not use it in the rain or wet conditions. If needed, protect a generator with a canopy. Never manipulate a generator\u2019s electrical components if you are wet or standing in water.<\/p>\n\n\n\n \u2022 Do not use electrical equipment that has been submerged in water. Equipment must be thoroughly dried out and properly evaluated before using. Power off and do not use any electrical equipment that has strange odors or begins smoking.<\/p>\n\n\n\n Carbon Monoxide Poisoning<\/strong><\/p>\n\n\n\n Carbon monoxide (CO) is a colorless, odorless, toxic gas. Many people have died from CO poisoning because their generator was not adequately ventilated.<\/p>\n\n\n\n \u2022 Never use a generator indoors or in enclosed spaces such as garages, crawl spaces, and basements. NOTE: Open windows and doors may NOT prevent CO from building up when a generator is located in an enclosed space.<\/p>\n\n\n\n \u2022 Make sure a generator has 3 to 4 feet of clear space on all sides and above it to ensure adequate ventilation.<\/p>\n\n\n\n \u2022 Do not use a generator outdoors if its placement near doors, windows, and vents could allow CO to enter and build up in occupied spaces.<\/p>\n\n\n\n \u2022 If you or others show symptoms of CO poisoning\u2014dizziness, headaches, nausea, tiredness\u2014get to fresh air immediately and seek medical attention. Do not re-enter the area until it is determined to be safe by trained and properly equipped personnel.<\/p>\n\n\n\n Fire Hazards<\/strong><\/p>\n\n\n\n \u2022 Generators become hot while running and remain hot for long periods after they are stopped. Generator fuels (gasoline, kerosene, etc.) can ignite when spilled on hot engine parts.<\/p>\n\n\n\n \u2022 Before refueling, shut down the generator and allow it to cool.<\/p>\n\n\n\n \u2022 Gasoline and other generator fuels should be stored and transported in approved containers that are properly designed and marked for their contents, and vented.<\/p>\n\n\n\n \u2022 Keep fuel containers away from flame producing and heat generating devices (such as the generator itself, water heaters, cigarettes, lighters, and matches). Do not smoke around fuel containers. Escaping vapors or vapors from spilled materials can travel long distances to ignition sources.<\/p>\n\n\n\n \u2022 Do not store generator fuels in your home. Store fuels away from living areas.<\/p>\n\n\n\n Noise and Vibration Hazards<\/strong><\/p>\n\n\n\n \u2022 Generator engines vibrate and create noise. Excessive noise and vibration could cause hearing loss and fatigue that may affect job performance.<\/p>\n\n\n\n \u2022 Keep portable generators as far away as possible from work areas and gathering spaces.<\/p>\n\n\n\n \u2022 Wear hearing protection if this is not possible.<\/p>\n\n\n\n For additional information:<\/em><\/strong><\/p>\n\n\n\n
