How Do I Safely Run a Portable Generator During a Power Outage?

When an ice storm or a line of fall thunderstorms takes out the power in central Oklahoma, a portable generator is the difference between a comfortable weekend and a scramble to save the food in your fridge and keep the pipes from freezing. But every year, the same storms that knock out power also send people to the hospital — or worse — from generators run the wrong way. As we head into the season when outages get longer and colder, it’s worth walking through how to use one safely before you’re doing it by flashlight in the wind.

A common call we start getting this time of year is from homeowners who bought a generator over the summer, stored it in the garage, and now want to know how to actually use it when the lights go out. The good news is that safe operation comes down to a handful of rules that never change.

The One That Actually Kills People: Carbon Monoxide

If you remember nothing else, remember this: a portable generator’s exhaust is deadly, and it kills fast.

A running generator produces carbon monoxide — an invisible, odorless gas — at a rate that can overwhelm a person in minutes in an enclosed or partly enclosed space. It is the single most common way generators injure and kill people during outages, and it happens most in cold weather, when the instinct to keep the unit “close and out of the storm” is strongest.

The rules are simple and non-negotiable:

• Run it outdoors only, at least 20 feet from the house, with the exhaust aimed away from the building.
• Never in a garage, carport, basement, crawlspace, shed, or on a porch — an open door or window does not make an enclosed space safe.
• Keep it clear of every door, window, and vent, including your dryer and HVAC intakes, so exhaust can’t drift back inside.
• Put working carbon monoxide detectors on every level of your home, especially near sleeping areas. If an alarm sounds, get everyone outside into fresh air first and ask questions later.

Modern generators increasingly include a built-in CO shutoff sensor. It’s a good backstop — but it is a backstop, not a license to run the unit any closer to the house.

Connecting It the Right Way

Once the generator is placed and running, you have two safe ways to get that power where you need it.

The simplest is heavy-duty extension cords run straight from the generator to individual appliances — the refrigerator, a space heater, a lamp, a phone charger. Use outdoor-rated cords in good condition, sized for the load and the distance; a cord that’s too thin or too long overheats and drops voltage. Uncoil cords fully so they don’t build up heat, and keep the connections up off wet ground.

The other way — the one that lets you run hardwired things like your furnace blower, well pump, or whole circuits — is a transfer switch or interlock installed at your panel. That’s permitted electrical work, and it’s the only legal, safe way to feed household wiring from a generator. What you must never do is plug the generator into a wall outlet to “power the house.” That backfeeds electricity onto the utility lines and can kill a lineworker working to restore your power. If you want your generator wired into the house properly, our electrical panel and generator work is where that starts.

Fuel, Heat, and Weather

A few more habits keep a generator from becoming a fire hazard:

• Never refuel a hot or running generator. Gasoline spilled on a hot engine or exhaust can ignite. Shut it down, give it a few minutes to cool, then refill.
• Store fuel properly — in an approved container, away from living space and any ignition source, not next to the water heater in the garage.
• Keep it dry. Run it on a level surface out of standing water, and if it’s raining or sleeting, shelter it with a purpose-built, open-sided generator canopy — never a tarp draped over the unit or an enclosure that traps exhaust.
• Don’t overload it. Add up what you’re running and stay within the generator’s rating; an overloaded unit overheats and can damage both itself and what’s plugged into it. Start the biggest motor loads first, then add smaller items.

The Bottom Line

A portable generator is one of the best things you can have when an Oklahoma storm drops the grid — as long as you treat it with respect. Keep it well outside and far from windows, protect your family with carbon monoxide alarms, feed appliances with proper cords, and only ever connect it to your home through a transfer switch installed by a pro. Handle those four things and a generator is exactly the safety net it’s meant to be.
