• Exposure to high concentrations of CO can lead to severe health problems, including headaches, dizziness, nausea, unconsciousness, and death.
• Key takeaway: Never operate a generator indoors, in garages, or near windows or doors that could allow CO to enter living spaces.

1.2 Fire Hazards Due to Fuel Spills or Overheating

• Generators use flammable fuels, such as gasoline or propane, which pose a significant fire risk.
• Fuel spills during refuelling can ignite, especially if the generator is hot.
• Overheating can occur if the generator is overloaded or lacks proper ventilation, leading to fires.
• Improper storage of fuel near the generator is also a huge fire hazard.
• Key takeaway: Always refuel the generator when it is cool and turned off, store fuel in approved containers away from the generator, and ensure adequate ventilation.

1.3 Electrical Shocks and Electrocution Risks

• Generators produce electricity, and improper handling can result in electrical shocks or electrocution.
• Damaged cords, wet conditions, and improper grounding can increase the risk of electrical accidents.
• Backfeeding, where generator power flows back into the utility grid, can energize power lines and pose a danger to utility workers.
• Key takeaway: Use only heavy-duty, outdoor-rated extension cords, keep the generator dry, and never attempt to connect the generator directly to your home’s wiring without a qualified electrician and a proper transfer switch.

1.4 Mechanical Injuries from Moving Parts

• Generators have moving parts, such as the engine and fan, which can cause mechanical injuries.
• Loose clothing, jewellery, or long hair can become entangled in these parts.
• Improper maintenance or tampering with the generator can also increase the risk of mechanical injuries.
• Key takeaway: Keep a safe distance from moving parts, wear appropriate clothing, and ensure the generator is properly maintained.

2. Safe Generator Installation and Placement

Proper installation and placement of your generator are crucial for ensuring safety and preventing accidents. The following guidelines should be strictly adhered to:

2.1 Choose a Well-Ventilated, Outdoor Location—Never Use Indoors

• Generators produce carbon monoxide (CO), a deadly gas. Operating a generator indoors, in garages, basements, or enclosed spaces is extremely dangerous and can lead to fatal CO poisoning.
• Always place the generator in a well-ventilated, outdoor location where fresh air can circulate freely.
• This placement is the most critical step in preventing CO-related injuries.

2.2 Maintain at Least 20 Feet of Distance from Doors, Windows, and Vents

• Position the generator at least 20 feet away from any doors, windows, and vents to prevent CO from entering your home or other occupied buildings.
• This distance ensures that exhaust fumes are dispersed safely, minimizing the risk of inhalation.
• Consider wind direction and placement, to prevent fumes from being blown back towards the home.

2.3 Protect the Generator from Rain and Moisture but Ensure Proper Airflow

• While the generator must be outdoors, it also needs protection from rain and moisture to prevent electrical hazards.
• Use a generator tent or canopy designed for outdoor use, but make sure it allows for adequate ventilation.
• Never operate a generator in standing water or in wet conditions without proper protection.
• Avoid placing the generator under eaves or other areas that may collect water.

3. Proper Fuel Handling and Storage

Safe handling and storage of fuel are essential to prevent fires and other hazards associated with generator use.

3.1 Use Only Manufacturer-Recommended Fuel Types

• Refer to your generator’s user manual to determine the correct fuel type (e.g., gasoline, propane, natural gas).
• Using the wrong fuel type can damage the generator and create safety hazards.
• Do not mix different fuel types.

3.2 Store Fuel in Approved Containers, Away from Heat Sources

• Store fuel in approved, labelled containers designed for gasoline or propane.
• Keep fuel containers away from heat sources, sparks, and open flames.
• Store fuel in a cool, dry, and well-ventilated area, away from living spaces.
• Do not store fuel in the same area as the generator.

3.3 Turn Off the Generator Before Refueling to Avoid Fire Hazards

• Always turn off the generator and allow it to cool down completely before refuelling.
• Hot engine parts can ignite fuel vapours, causing a fire or explosion.
• Refuel in a well-ventilated area, away from any potential ignition sources.
• Wipe up any spilt fuel immediately.

4. Electrical Safety Measures

Electrical safety is paramount when operating a generator. One of the most critical precautions is to avoid backfeeding. Backfeeding occurs when generator power flows back into the utility grid, energizing power lines and creating severe risk for utility workers and neighbours. To prevent this, always use a professionally installed transfer switch. This device isolates your home’s electrical system from the utility grid, ensuring that generator power is safely directed. When using extension cords, opt for heavy-duty, outdoor-rated cords designed for generator use.

Standard household extension cords may overheat and pose a fire hazard. Furthermore, keep all electrical connections dry and protected from water exposure. Moisture can lead to electrical shocks and damage to the generator. Use weatherproof covers for outlets and connections, and never operate the generator in standing water or during heavy rain without proper protection. By adhering to these measures, you can significantly reduce the risk of electrical accidents and ensure the safe operation of your generator.
