Power Outage and Portable Generator Safety

A garage, carport, porch, door, or window does not make exhaust safe.

CPSC says portable generators belong outside only, at least 20 feet from the home, with exhaust directed away. Use working carbon-monoxide alarms on every level and outside sleeping areas, and leave the building for fresh air if an alarm sounds or symptoms appear.

A generator can energize wiring and utility lines that workers believe are de-energized.

Never connect a portable generator directly to home wiring or a wall receptacle. Use only manufacturer-permitted cord connections for individual loads, or have a qualified electrician install and explain listed transfer equipment that isolates utility and generator sources.

Motors and compressors may need more power at startup than while running.

Record label watts for refrigeration, pumps, communications, lighting, and other essentials. Add simultaneous running loads, identify the single largest additional startup surge, and compare both continuous and starting ratings. Do not assume a large plug or nameplate means every load is compatible.

Wet connections, damaged cords, hot refueling, and indoor storage add separate hazards.

Follow the generator manual for dry operating conditions, cord gauge and length, grounding instructions, cooling, refueling, and storage. Stop the engine and allow it to cool before refueling. A damaged cord, shock sensation, repeated trip, or required home-wiring connection belongs with qualified service.
