Generator Placement and Ventilation Safety

June 22, 2025

Gas-powered generators produce deadly carbon monoxide (CO) and should never be used indoors or in poorly ventilated areas.

Why It Matters:
Carbon monoxide is colorless, odorless, and lethal — and construction workers have died from CO poisoning when generators were placed near open doors, windows, or inside partially enclosed spaces. OSHA and CDC warn that even outdoor use can be dangerous if ventilation is poor.

Key Points:

  • Always place generators outdoors in well-ventilated areas — at least 20 feet from any structure, doors, or windows.
  • Never run generators inside trailers, sheds, or garages, even if windows are open.
  • Position the exhaust to blow away from people and occupied areas.
  • Use CO detectors inside nearby trailers or enclosed spaces if a generator is operating nearby.
  • Secure the generator to prevent movement or tipping, especially on uneven terrain.

✅ Keep generators outside and airflow moving — CO kills quickly and silently.

Ask the Crew:

  • Where is our generator placed? Is it at least 20 feet from the nearest structure?
  • Do we have proper airflow around the generator?
  • Are we monitoring enclosed trailers for carbon monoxide exposure?
