Can You Run Generator In Garage? (No, But Why?)

A generator is incredibly helpful just after an ice storm or hurricane. Moreover, if you are living in an off-grid farmhouse, a generator is mandatory for you to run the necessary home appliances.

Most people use a portable generator for temporary use. Since we store the portable generator in the garage, we tend to run the generator from the garage. 

But have you ever thought, should you run your generator in the garage? 

You should not run your generator in the garage at all. Generators produce carbon monoxide (CO) which is a literally silent killer. So, it is strictly prohibited to run your generator in a confined place like in a garage or basement. 

Anyway, I have elaborately discussed why you should not run your generator in the garage and how to safely run your generator in the latter part of this article. so, let’s get started! 

Why Should You Not Run Generator In The Garage? 

A generator is pretty useful stuff, no doubt. But if you can not handle this machine, there is a high chance of an accident. 

Power outage is very common after a heavy ice storm or hurricane. Or, if you are living in an off-grid area, you can not survive without an alternative power source. 

Most people want to run a generator in the garage or in the porch due to prevent theft or save the machine from rain and wet condition. Read and learn why should you not run a generator on the porch.

Yes, this is a good idea indeed. But the main problem is Carbon Monoxide which is known as the silent killer of the human body. 

If you run your generator in the garage continuously, in almost 100% of cases you will find elevated carbon monoxide in the air. If you are near the generator, there is a chance of the presence of high CO in your blood also. 

Believe me, CO-related call is very common to the fire department. You could go to your local fire department to learn more about the carbon monoxide case for running a generator in the garage.

FAQ
