Can a Generator Cause Carbon Monoxide Poisoning?
Short answer: absolutely, if it's used the wrong way. This silent gas can build up fast, turning a lifesaver into a real danger. Keep reading to learn the warning signs, safety tricks, and how to run your generator without risking your family.

Are Generators Safe?
Generators are generally safe when used correctly outdoors with proper ventilation, but they pose serious risks if misused, including carbon monoxide poisoning, electrical hazards, fire, and fuel spills. Key safety steps include never running a generator indoors or in enclosed spaces, keeping it away from windows and doors, using proper extension cords, and installing CO detectors. Regular maintenance, correct refuelling practices, and following manufacturer guidelines are essential to prevent accidents. Always prioritise safety by understanding the risks and taking precautions before and during use.
Understanding Carbon Monoxide from Generators
What is Carbon Monoxide and Why is it Dangerous?
Carbon monoxide is a colourless, odourless gas produced whenever fuel burns. It's impossible to detect without a CO alarm. In an enclosed space, it builds up fast—and at high concentrations, it's lethal within minutes.
How Do Generators Produce Carbon Monoxide?
Every time a petrol, diesel, or LPG engine runs, it produces CO as a byproduct of combustion. The exhaust pipe pushes it out, but if there's no airflow to carry it away, CO collects around the machine and nearby spaces.
Generator Carbon Monoxide: Key Statistics and Risks
In Australia, dozens of people are hospitalised each year due to generator-related CO poisoning. Many incidents happen during storms or blackouts when people mistakenly bring generators inside for shelter. It's one of the most preventable emergencies out there.
Generator Carbon Monoxide Safety and Prevention
Safe Placement: Where to Put Your Generator
The rule is simple: always outside, always away. Run your generator at least 6 metres from any door, window, or vent. Point the exhaust away from your home. Don't run it under an awning, in a garage, or near an air intake.
Ventilation Requirements for Generator Use
Open space is your friend. CO disperses quickly outdoors, but even a semi-enclosed carport or verandah can trap dangerous levels. If you can smell fumes, the generator is too close.
How to Detect Carbon Monoxide from Your Generator
Install a battery-powered CO alarm inside your home, near sleeping areas. Test it monthly and replace the batteries twice a year. This simple step could save your family's life during a blackout.
Carbon Monoxide Poisoning Symptoms to Watch For
Symptoms start mild: headache, dizziness, nausea, and confusion. As levels rise, it can cause loss of consciousness and death. If anyone in the home feels unwell while the generator is running, get everyone out immediately and call 000.
Safe Generator Operation Practices
Never Run a Generator Indoors
This applies to garages, sheds, basements, tents, and covered patios. Even with doors open, the risk is too high. It doesn't matter how quiet the generator is—silent generators still produce CO.
How Far Should a Generator Be from the House?
Six metres minimum. The further the better. Position it so the prevailing wind blows exhaust away from the building. When using portable generators, this distance is non-negotiable.
Generator Safety Tips During Power Outages
Before starting, check the placement. While it's running, check in on CO detector readings. When finished, shut it down before heading inside, and let it cool before covering or storing. This applies to all generators for home backup setups.
What to Do If You Suspect Carbon Monoxide Poisoning
Get everyone out of the building immediately. Don't stop to grab belongings. Call 000 from outside. Don't re-enter until emergency services say it's safe.
Generator Selection and CO Considerations
Do All Generators Produce Carbon Monoxide?
Yes—any generator running on petrol, diesel, or gas produces CO. There's no such thing as a CO-free fuel-burning generator. If you need indoor power, consider a portable power station instead—they run on batteries and produce zero emissions.
CO-Safe Generators: What Features to Look For
Some newer generators include automatic CO shutoff technology. If CO levels rise near the engine, the unit shuts itself down. It's a great feature, but it doesn't replace safe placement—it's a backup, not a substitute.
Conclusion: Staying Safe with Generator Carbon Monoxide
Carbon monoxide from generators is invisible, silent, and deadly—but entirely avoidable. Always run your generator outdoors with plenty of clearance from your home. Fit a CO alarm, keep it serviced, and educate everyone in the household. When in doubt, step back outside.
