The non-negotiables
- Outdoors only, at least 20 feet from the building, exhaust pointing away from doors, windows and vents. A garage, carport, porch or shed is indoors.
- Battery-operated CO alarms on every level, tested. This is the only thing that warns you in time.
- Never backfeed into a wall outlet. Use a transfer switch, or plug appliances directly into the generator.
- Refuel only when cool, and outdoors. Fuel on a hot engine or exhaust ignites.
- Keep it dry. Do not run it in standing water or rain without cover that still allows ventilation.
Running it well
- Manage the load. Start the largest appliance first, then add others. Running a generator near its limit for hours shortens its life and risks tripping.
- Prioritise: refrigerator/freezer, a few lights, phone charging, medical equipment, fans. Not air conditioning, unless the unit is sized for it.
- Never plug a generator into household wiring without a transfer switch installed by a qualified electrician.
- Check the oil as the manual requires. Most small generator failures during storms are oil or fuel problems.
- Shut it down and let it cool before moving it.
If anyone feels unwell
Headache, dizziness, nausea, confusion or weakness while a generator is running means possible carbon monoxide exposure. Get everyone outside into fresh air immediately and call for help. Do not stop to open windows.
