Rain and exhaust are separate hazards
Water can create shock and equipment hazards. Carbon monoxide can kill when the generator is moved into an enclosed or partly enclosed space. A safe setup must solve both problems.
Read the exact owner's manual before choosing a cover. Do not operate or connect equipment while standing in water.
Use protection designed for operation
A storage cover is not necessarily a running cover. Operational protection must keep rain off outlets and controls while allowing cooling and exhaust flow.
Anchor the shelter for wind, maintain clearances, direct exhaust away, and inspect cords and ground-fault protection.
Prepare before the storm
Select the outdoor location, cord route, shelter, fuel location, and lighting before bad weather. Test the full setup during normal conditions.
Shut down and cool the generator before refueling. Keep fuel in approved containers and follow local fire rules.
Frequently asked questions
Can I cover a running generator with a tarp?
An improvised tarp can trap heat, obstruct exhaust, collapse, or contact hot parts. Use operating protection specifically designed for generators.
Can a generator run in a shed with doors open?
No. Sheds and other enclosures can collect deadly carbon monoxide.
Can I use a generator under a canopy?
Only when the manufacturer permits the arrangement and it preserves outdoor distance, exhaust clearance, cooling, and weather protection.
