Carbon monoxide deaths from generators happen when they’re used too close to homes or in areas without airflow. Generators release a gas you can’t see or smell, and it can kill within minutes.
The Consumer Product Safety Commission says most deaths occur during power outages. Always use generators outdoors and maintain a safe distance around them.
Portable generators help during blackouts, but unsafe use can turn deadly. At Grounded Electric, our licensed electricians teach safe setup and maintenance.
Robert “Bobby” Mulholland and Barret Abramow lead our team to ensure all installations meet safety codes and reduce the risks of CO poisoning.
Key Takeaways
- Portable generators cause many carbon monoxide deaths during power outages.
- Since 2011, more than 700 people have died due to poor ventilation and misuse.
- Keep generators 20 feet from your home and point the generator’s exhaust away.
- New models with CO shutoff systems lower risks.
- Use carbon monoxide detectors with battery backup for safety.
Can a Generator Cause Carbon Monoxide Poisoning?
National and Demographic Trends in CO Deaths
The CPSC reports over 700 generator-related CO deaths between 2011 and 2022. Most victims were adults aged 30–60. Many accidents occur during winter or storm seasons when homes rely on generators that are too close to windows or vents.
Newer units with CO-sensing shutoffs have reduced fatalities; however, older ones remain a risk. Most cases occur when generators run overnight for heat or fridges.
Compared to heaters or stoves, generators produce significantly more carbon monoxide in a shorter amount of time. These patterns demonstrate the strong connection between generators and carbon monoxide poisoning.
Generator Carbon Monoxide Deaths and Key Statistics
Generators release a gas that’s colorless and odorless. Used indoors or near windows, it builds fast and causes carbon monoxide generator deaths in minutes.
The Consumer Product Safety Commission (CPSC) links most carbon monoxide poisoning generators deaths to poor ventilation. The product safety commission CPSC warns that placement and airflow are key to prevention.

Reducing the Risk Through Proper Use
Bobby Mulholland says homeowners must follow the owner’s manual. Keep the generator 20 feet away and face the generator’s exhaust away from doors and windows to prevent carbon monoxide CO poisoning.
How Much CO Does a Generator Produce?
Grounded Electric’s Licensed Expertise
Grounded Electric is a licensed electrical contractor in New Jersey. Led by Bobby Mulholland and Barrett Abramow, our team ensures that every installation complies with UL 2201 and state codes.
Each project includes safety checks for exhaust, grounding, and shutoff features. Read our generator guide for simple setup and safety steps to learn how to use your generator safely.
Dangerous Carbon Monoxide Levels and Exposure Time
A small generator can fill a closed garage with deadly gas in minutes. CO builds faster than most people realize, often reaching fatal levels within five minutes.
Do Generators Produce CO When Off?
When off, generators don’t make CO, but fumes can linger if airflow is poor. This invisible gas can stay trapped in small spaces long after shutdown.
Ensuring Generators Are Working Properly
Grounded Electric’s team checks that all safety features work properly. A damaged muffler or blocked vent increases the risk of carbon monoxide poisoning.

Carbon Monoxide Poisoning Symptoms
Early signs include headache, dizziness, and nausea. If ignored, confusion and fainting can follow.
High CO levels can kill in minutes. If anyone feels sick near a generator, go outside and call 911 right away.
How to Prevent Carbon Monoxide Poisoning From a Generator
Safe Generator Placement and Ventilation Guidelines
Operate generators outside only:
- Stay 20 feet from all doors, vents, or windows.
- Face away from the house.
- Never use one in garages or basements.
Learn more about avoiding carbon monoxide from a generator outside and ensure proper airflow to stay safe.

Using Carbon Monoxide Detectors and Battery Backup
Install detectors near bedrooms and test them often. See our guide on picking a generator with a carbon monoxide detector for safer operation. Barret Abramow suggests models with battery backup for power outages.
Safety Features and Maintenance
Buy generators with automatic CO shutoff safety features. They detect high levels and stop the engine. Always read the owner’s manual and follow maintenance steps.
The Real Cost of Ignoring Generator Safety
Every year, families lose lives to preventable carbon monoxide poisoning. Most of these deaths could be avoided with better ventilation and the use of working CO detectors.
Generator Safety Standards and Regulations
CPSC and UL 2201 Safety Requirements
The Consumer Product Safety Commission and UL 2201 require generators to have built-in sensors and safer exhaust systems. Modern models with CO-sense tech turn off automatically when gas levels rise.
Ensuring Compliance and Installation
Grounded Electric meets all safety standards for each project. Our team checks exhaust direction and ventilation. Bobby Mulholland says certified equipment is key to preventing generator carbon monoxide death.
Upgrading Older Models
If your unit is old, have an electrician inspect it to ensure it’s working properly. Add CO sensors or upgrade to newer models for better safety. Visit our page on how to choose a generator for your home for trusted options.
Key Takeaways for Homeowners
Safety Checklist Before Operating a Generator
Before starting your generator:
- Keep it 20 feet from the home.
- Point exhaust away from openings.
- Test CO alarms twice a year.
- Check the safety feature before running.
When to Contact a Licensed Electrician
If it fails to start or emits fumes, stop using it and call Grounded Electric. Barret Abramow and his team can make sure it’s safe.
Emergency Steps
If anyone experiences symptoms of CO poisoning, leave the area immediately and call 911.
Before You Start Your Generator
Always:
- Clear vents and face exhaust away.
- Keep 20 feet from windows or doors.
- Test CO detectors and replace batteries.
- Review the owner’s manual before running.
- Confirm safety features are working.
If you need help checking your system or want expert guidance, schedule an appointment with Grounded Electric. Our licensed electricians can inspect your setup, improve safety, and ensure your generator runs efficiently before the next outage.
