You may have seen ads for portable generators and thought about buying one. But can you run a portable generator in a shed, perhaps when there is a power outage?

It is not advisable to run a portable generator in a shed. While a shed may provide some protection from the elements, it will not protect you from carbon monoxide (CO) poisoning.

If you must use a portable generator, make sure to follow safety tips. In this blog post, we’ll take a look at the viability of using a portable generator in a shed and what you need to consider before making your purchase. Stay safe out there!

Can You Run a Portable Generator in a Shed

Indoor spaces like sheds might seem like a good choice, but they’re actually the worst possible option to run a portable generator for many reasons.

If you’re like most people, you probably don’t give much thought to your home’s electrical system.

But when a storm hits and the power goes out, suddenly you’re faced with the reality that a little knowledge can go a long way.

If you have a portable generator (Amazon Link), you may be tempted to run it in a detached shed in order to keep the noise down.

However, this is not safe for several reasons. First, there is a risk of carbon monoxide poisoning if the shed is not properly ventilated.

Second, the generator can become overloaded and overheat, posing a fire hazard.

And finally, the noise from the generator can be extremely loud and disruptive, making it difficult for your neighbors to enjoy their own property.

So, while a portable generator can be a valuable asset during a power outage, it’s important to use it safely and follow all manufacturer’s instructions.

What are the Issues With Running a Portable Generator in a Shed

If you are considering running a portable generator in a shed, there are a few things you should take into account. The main issues include ventilation, fuel storage, and safety.

  1. Ventilation- Ventilation is important because portable generators produce carbon monoxide (CO) gas. This gas is colorless, odorless, and poisonous. If there is not enough ventilation in the shed, the CO gas can build up and cause serious health problems or even death.
  2. Fuel Storage – Fuel storage is another important consideration. Portable generators must be fueled with gasoline, and it is important to store the gasoline properly. Gasoline should be stored in a cool, dry place. It should also be stored in a container that is specifically designed for gasoline storage.
  3. Fire and Burn Hazards – Another safety concern when running a portable generator in a shed is the risk of fire or burns. The exhaust from the generator can get very hot, and if it comes into contact with flammable materials, it can start a fire. Additionally, the generator itself can get very hot, and if you touch it, you could be seriously burned.
  4. Noise pollution – Another downside to running a portable generator in a shed is the noise it produces. Portable generators can be quite loud, and if you are not careful, the noise can be a nuisance to your neighbors.
  5. General Safety – Safety is always a concern when using any type of machinery. Portable generators can be dangerous if they are not used properly.

Be sure to read the owner’s manual carefully and follow all safety instructions. Never operate a portable generator indoors; always keep it away from children and pets.

Can I Run a Portable Generator in a Shed With Plenty of Ventilation

If your shed has plenty of ventilation, then you should be fine to run your generator inside. However, you should still take some precautions.

Make sure the exhaust from the generator is not directed toward the door or any windows. This will help to prevent the build-up of carbon monoxide gas.

It is also a good idea to keep a fire extinguisher inside the shed, just in case.

However, running a generator inside a shed can be dangerous if there isn’t enough ventilation. When generators run, they produce carbon monoxide gas.

This gas is odorless and colorless, so you might not realize that it’s building up in your shed. If there’s not enough ventilation, the carbon monoxide could reach dangerous levels and make you sick or even kill you.

So if you run a portable generator in a shed, ensure there’s plenty of ventilation to keep everyone safe.

Where is the Best Place to Run a Portable Generator

A portable generator can be a lifesaver during a power outage. But it’s important to use them safely to avoid carbon monoxide poisoning.

Never run a generator in an enclosed space or indoors. The best place to run a portable generator is outdoors, at least 20 feet from the house, with the engine exhaust directed away from windows and doors.

Most generator-related injuries and deaths involve CO poisoning from generators used indoors or in partially enclosed spaces, so it’s crucial to follow this advice.

If you need to use a generator indoors, ensure to ventilate the area well and keep an eye on the CO detector.

Stay safe and be prepared during power outages!


Portable generators can be a lifesaver in an emergency, but it’s important to use them safely.

Can you run a portable generator in a shed? It is never advisable to do so because of the hazards involved.

However, if you must run one in an indoor space, make sure to keep it at least 20 feet from the house and point the engine exhaust away from windows and doors.
