No, it is not safe. Running it in any enclosed or partially enclosed space, even with a door open, risks fatal carbon monoxide poisoning.
Here's what you need to do, every time:
- Only run the generator outside, far away from windows, doors, and vents.
- Keep it at least 3 feet (1 meter) away from buildings and other equipment for proper cooling and to prevent fire risk from the hot exhaust.
- Never operate it inside a house, garage, basement, crawlspace, or shed.
Why this is critical: The exhaust contains toxic carbon monoxide (CO), which you cannot see or smell. Breathing it can kill you in minutes. Early symptoms include headache, fatigue, nausea, and dizziness.
Heads up: For added safety, install battery-operated CO alarms with battery backup on every level of your home and outside sleeping areas. If you suspect CO exposure, get to fresh air immediately and seek medical attention.
