A fuel generator can be useful during an outage. It can also become the most dangerous item in the plan if it is used casually.

The danger is not theoretical. Carbon monoxide is odorless, invisible, and deadly.

Non-negotiable placement

Ready.gov and CDC both say fuel generators should be used outdoors and away from windows, doors, and attached garages. Ready.gov gives a specific distance: at least 20 feet away from windows, doors, and attached garages.

Never run a generator:

  • inside a home
  • inside a garage
  • on a balcony
  • near doors, windows, vents, or sleeping areas
  • in an enclosed or partly enclosed space

Use working carbon monoxide alarms on every level of the home. Battery backup matters because the grid may be down.

Backfeed is not a shortcut

Do not plug a generator into a wall outlet to power the house. That can energize wiring in unsafe ways and endanger utility workers, neighbors, and your own equipment.

If you want to power circuits, use code-compliant transfer equipment installed by a qualified electrician.

Cord and weather basics

  • use outdoor-rated heavy-duty cords sized for the load
  • keep connections dry
  • do not overload cords or power strips
  • keep the generator protected from rain without enclosing exhaust
  • let the generator cool before refueling
  • store fuel safely and according to local rules

Decision section

Choose a generator only if you can answer:

  • Where will it sit safely outdoors?
  • How will exhaust stay away from openings?
  • How will fuel be stored?
  • Which loads will it power?
  • Will loads use cords or transfer equipment?
  • Who will maintain it between outages?

If you cannot answer those, choose a battery-first plan or hire help before the next storm.
