Carbon Monoxide Safety: The Rule That Saves Lives
Of everything in this whole series of guides, this is the page I most wish everyone would read. A generator's exhaust carries carbon monoxide — a gas you cannot see, cannot smell, and cannot taste — and it kills people every year in situations that were entirely preventable. This guide is a full, calm walk through what CO is, why the rules exist, and the handful of habits that keep it from ever becoming your family's story. There's a printable, 29-page guide up top if you'd like the whole thing on hand.
Common Questions
1 Why is carbon monoxide so much more dangerous than, say, a burning smell or smoke?
Because your senses are no help at all. Carbon monoxide (CO) has no color, no smell, and no taste — there's nothing to notice until you already feel sick, or worse, you don't feel anything before you pass out. That's exactly why the safety rules focus on prevention — distance and placement — rather than waiting to detect a problem.
2 How far away is actually far enough?
Run the generator outdoors only, at least 20 feet from the house, with the exhaust pointed away from doors, windows, and vents. In testing, a generator placed just 10 feet from a home drove indoor CO levels above 200 parts per million — a level that can be dangerous, even fatal, with continued exposure. Twenty feet isn't an arbitrary number; it's the difference that keeps that exhaust out of your living space.
3 What about running it in the garage with the door open?
Please don't — this is the single most common mistake, and it's deadly. A garage, even with the big door wide open, traps exhaust far more than open air does. The same goes for a basement, shed, crawlspace, or carport. A cracked window or door is not enough. Outdoors, away from the structure, is the only safe answer.
4 What do carbon monoxide symptoms actually feel like?
Often surprisingly mild at first — a headache, feeling dizzy or a little nauseated, or just unusually sleepy. It's easy to mistake for being tired or coming down with something. If anyone in the house feels that way while a generator is running nearby, or a CO alarm sounds, treat it as real: get everyone into fresh air immediately and call 911.
5 Do the newer generators with a CO shutoff sensor make this less of a worry?
They help, and they're a genuinely good feature to look for — many recent models sense rising CO and shut the engine down automatically. But think of it as a backup, not the plan. Correct placement, every single time, is still what actually keeps carbon monoxide out of your home in the first place.
6 Can you help make sure our whole family understands this?
Absolutely, and I'd love to. Walking a household through generator safety — CO, fuel handling, all of it — is one of my favorite parts of a home visit. I'll help you pick a safe spot, get your CO alarms in place, and make sure everyone from the grandkids to the grandparents knows the rule. $99 flat. Call or text (330) 200-8042.
Want Me to Help With Yours?
Getting a backup generator picked, set up, and safe is one of the things I'm glad to do in person. I bring the patience and the know-how — you keep your seat. We'll get it starting, sort out the fuel and the safe hookup, walk through running your essentials, and make sure everyone knows the carbon-monoxide basics. $99 flat, and every visit is 30-day come-back-free. (330) 200-8042.
Would you rather I just do this for you?
No shame in it — plenty of folks would rather hand it off, and that's what I'm here for. I'll come to your home, set it up right, and make sure it's working before I leave. Flat $99 per visit — no jargon, no upsell, and every visit is 30-day come-back-free.
Not a hardware job? I can often fix it remotely for $49 — a secure screen-share, up to 2 hours, that you watch the whole time and can end whenever (included free for $39/mo Support Plan members, and it counts toward the $99 if it turns out I need to come out).
