Generator Carbon Monoxide Safety: Avoiding the Hidden Danger
A generator’s exhaust produces carbon monoxide, a colorless, odorless, deadly gas, so the key safety rules are to run it outdoors only, well away from the house and its windows, doors, and vents with the exhaust pointed away, use working carbon monoxide detectors in the home, and know the poisoning symptoms. Newer CO shutoff generators add protection. Never run a generator in a garage or enclosed space, even with the door open, since CO builds up fast.
Every hurricane season, generator carbon monoxide poisoning kills people, often when a generator runs too close to or inside a home, because the exhaust gas is invisible and has no smell. In Tampa, where a storm outage may have a generator running for days, understanding this hidden danger and how to avoid it is the single most important part of using one safely. The precautions are simple but life saving. This guide covers safe placement, carbon monoxide detectors, CO shutoff generators, and the symptoms to know.
Why Generator CO Is So Dangerous
A generator’s exhaust is deadly and you cannot sense it.
A generator’s engine gives off carbon monoxide, a colorless, odorless gas that is deadly. Because you cannot see or smell it, it can build up and overcome people before they realize, which is why generator carbon monoxide poisoning kills people every year, often after storms. The gas can seep into a home from a generator running too close, in a garage, or near a window, so the danger is real and hidden.
Run the Generator Outdoors, Far Away
The first line of defense is placement.
Use CO Detectors and CO Shutoff Generators
Detectors and built in sensors are your safety net.
| Safeguard | What it does |
|---|---|
| Home CO detectors | Battery backed carbon monoxide alarms in the home warn you if CO gets in |
| CO shutoff generators | Newer generators have a built in CO sensor that shuts the engine off if CO builds up nearby |
| Working batteries | Detectors are useless with dead batteries; test them before storm season |
Know the Symptoms
Recognizing CO poisoning early can save lives.
The Takeaway
To recap: a generator’s carbon monoxide is colorless, odorless, and deadly, so run it outdoors only, well away from the house and its openings with the exhaust pointed away, use working CO detectors in the home and a CO shutoff generator, and know the poisoning symptoms.
In a Tampa hurricane outage, when generators run for days, these carbon monoxide precautions are the most important safety step you can take, more than any other part of running one.

Frequently Asked Questions
Why is generator carbon monoxide so dangerous?
Because carbon monoxide from a generator’s exhaust is colorless and odorless, so you cannot see or smell it, and it can build to deadly levels before anyone notices. It kills people every year, often after storms, when generators run too close to or inside homes.
How far should a generator be from the house?
Well away, typically well over the length of the house, and away from all windows, doors, and vents, with the exhaust pointed away from the home. Never run it in a garage, shed, or any enclosed space, even with the door open, since carbon monoxide builds up fast.
Can I run a generator in the garage with the door open?
No, never. Even with the door open, a garage or enclosed space lets deadly carbon monoxide build up quickly. A generator must always run outdoors, well away from the house and its openings, with the exhaust directed away from the home.
What is a CO shutoff generator?
A newer generator with a built in carbon monoxide sensor that automatically shuts the engine off if CO builds up nearby, adding a safety layer beyond placement. Combined with working carbon monoxide detectors in the home, it helps protect against the hidden danger of generator exhaust.
What are the symptoms of carbon monoxide poisoning?
Headache, dizziness, weakness, nausea, and confusion are early signs. If anyone develops these while a generator is running, treat it as possible carbon monoxide poisoning, get everyone outside to fresh air immediately, call for help, and do not re enter until the air is safe.
