Can You Cover a Generator While It Running?

Covering a generator while it is running is not recommended, as it can lead to overheating, reduced airflow, and increased risk of fire. Generators require proper ventilation to dissipate heat and exhaust fumes. Instead, place the generator in a well-ventilated area or use a specially designed enclosure with adequate ventilation to ensure safe and efficient operation.

Can You Cover a Generator While It Running?

Generators are essential tools for providing backup power during emergencies, outdoor events, or in off-grid locations. They are incredibly versatile and can be lifesavers in many situations. This article offers a brief and to-the-point analysis of whether or not you can cover a generator while it’s running.

Why You Shouldn’t Cover a Running Generator?


Generators produce a significant amount of heat during operation. Covering a running generator can impede the airflow needed to dissipate this heat, leading to overheating. An overheated generator may suffer reduced efficiency, increased wear and tear, and even permanent damage to its components.

Reduced Airflow

Airflow is vital for the cooling of a generator’s engine and other components. Covering a running generator can restrict the airflow, leading to a build-up of heat, which may cause your generator to overheat and malfunction. Proper ventilation is crucial for the generator’s longevity and performance.

Carbon Monoxide Buildup

Generators emit exhaust fumes, including carbon monoxide (CO), which is a colorless, odorless, and deadly gas. Covering a running generator can cause these fumes to accumulate, creating a potentially lethal environment for those nearby. Ensuring that your generator is placed in a well-ventilated area can help prevent CO buildup and protect the health and safety of those around it.

Fire Hazard

Covering a running generator with flammable materials such as blankets, tarps, or plastic sheets can create a fire hazard. The heat generated by the generator, combined with the lack of airflow, can cause these materials to ignite, leading to a dangerous fire that may spread rapidly.

What You Can Do Instead

Use a Generator Enclosure

To protect your generator from the elements, consider using a specially designed enclosure. These enclosures are made to house generators safely and provide adequate ventilation to prevent overheating and carbon monoxide buildup. They are typically weather-resistant and can protect your generator from rain, snow, and debris.

Make sure to choose an enclosure that is compatible with your generator model and follow the manufacturer’s guidelines for proper installation and usage. In this section, we’ll delve deeper into the various aspects of using a generator enclosure.

Types of Generator Enclosures

There are several types of generator enclosures available on the market, and it’s essential to choose the one that best suits your needs and your generator’s specifications. Some common types include:

  1. Portable Generator Enclosures: These enclosures are designed for portable generators and are typically lightweight and easy to transport. They usually have a simple, tent-like structure and are made from weather-resistant materials like polyester or vinyl.
  2. Permanent Generator Enclosures: Permanent generator enclosures are more robust, durable structures built for stationary generators, typically used for standby power during emergencies or extended power outages. They are made from weather-resistant materials such as aluminum, stainless steel, or fiberglass, and often include soundproofing features to reduce noise levels. These enclosures require professional installation and are designed to last for an extended period.
  3. Acoustic Enclosures: Acoustic enclosures are designed to reduce generator noise significantly. These enclosures usually have sound-absorbing materials lining the interior walls, minimizing noise pollution and making the generator more neighborhood-friendly.

Features to Look For

When choosing a generator enclosure, consider the following features to ensure you’re making the best choice:

Ventilation: Adequate ventilation is crucial for any generator enclosure, as it allows for proper airflow to prevent overheating and carbon monoxide buildup. The enclosure should feature vents or openings that allow air to circulate freely while preventing water or debris from entering.

Weather Resistance: A generator enclosure should protect the generator from various weather conditions such as rain, snow, and extreme temperatures. Look for enclosures made from weather-resistant materials, featuring seals or gaskets to prevent water infiltration, and a sloped roof to allow snow and water runoff.

Noise Reduction: Some generator enclosures come with soundproofing features, such as insulated walls and noise-absorbing materials, to minimize the noise generated during operation. This can be especially important if your generator is located near residential areas or if you require a quiet environment.


Covering a running generator is not recommended due to the risks of overheating, reduced airflow, carbon monoxide buildup, and fire hazards. To ensure the safe and efficient operation of your generator, it is essential to place it in a well-ventilated area or use a purpose-built enclosure with proper ventilation.

Generator enclosures come in various types, including portable, permanent, and acoustic options, and offer features such as weather resistance and noise reduction. By selecting the right enclosure for your generator and following the manufacturer’s guidelines, you can protect your investment and maintain a safe environment while enjoying the benefits of reliable backup power.

Frequently-Asked Related Questions (FAQs)

Can I leave the cover on my generator all the time?

While it’s technically possible to leave a cover on your generator all the time, it’s not recommended. Your generator needs proper ventilation to run safely and efficiently, and a cover that is left on all the time could restrict airflow and cause the generator to overheat. It’s best to only use the cover when the generator is not in use or when you’re transporting it.

Can I use any type of cover for my generator?

No, you should only use a cover that is specifically designed for your generator. Using a cover that is not designed for your generator could cause it to overheat and potentially cause a fire. Additionally, a cover that doesn’t fit properly or doesn’t provide proper ventilation could also damage your generator.

Can you move a generator while it running?

No, you should not move a generator while it’s running. Doing so poses safety hazards, such as burns from hot surfaces, accidental spills of fluids, and tripping over cords. Additionally, sudden movements may damage the generator’s internal components. Always turn off the generator before relocating it.
