Backup generator is a lifesaver, especially in emergencies like storms, hurricanes, and other natural disasters. You can use a BISON generator to power your entire house for days. In addition to residential use, generators are also very useful in construction, workplaces, camping, RVs, and more. While Mobile generators (or any other type) look and work simply, they can be very dangerous (sometimes life-threatening) if you don’t take the necessary safety measures. The apparent hazard associated with generators is electric shock. But that’s not what we’re talking about here today.

Here we discuss the hazards of highly toxic carbon monoxide (CO) gas produced by fuel combustion in generators. We will also answer a common question many generator owners ask: “How much should the generator distance be from home?“.

We don’t want you to feel intimidated or worried about using a generator, but we point out that powerful machines like generators can be deadly if misused.

If you’re new to generators or planning to purchase your first generator, we hope this guide to placing generators around your house helps you avoid mishaps.

Generators and carbon monoxide

No matter what fuel your generator uses, burning the fuel produces carbon dioxide (CO2) and carbon monoxide (CO). While fuel combustion releases other gasses, these two are the main products we must be aware of and wary of.

Again, between carbon dioxide and carbon monoxide, the latter is far more dangerous.

Carbon monoxide is an unwanted by-product of fuel combustion. While normal combustion produces small amounts of carbon monoxide, it can be harmful if the fuel doesn’t burn completely. In this case, the amount of carbon monoxide released is considerable.

The worst thing about this gas is that it is colorless and odorless. If carbon monoxide is inhaled, it can lead to carbon monoxide poisoning, which can have some adverse health effects.

Inhaling small amounts of carbon monoxide can cause severe headaches, vomiting, nausea, tiredness, and prolonged dizziness. However, if the number is slightly larger, it will cause severe illness and even death.

How much should the generator distance be from home?

Now that we’ve seen how generators and the carbon monoxide gas they emit can affect our health, you’re probably asking how to use them safely. Or, more precisely, the right question is how far away the generator should be from the house.

The simple answer is that it should be as far away as possible. But that might not be possible in an installation because you have to deal with wiring, losses, and other issues.

While there are no definitive numbers on how far a generator should be from a house, many experts at these organizations and agencies recommend at least 20 feet between the house and the generator.

This recommendation has some additional requirements. Some of them are:

Follow the 20-foot distancing rule. If that’s impossible, try to place the generator at least 15 feet away from the house. Worst case scenario, don’t place your generator within 5 feet of your home.
No worries about powering appliances with a generator at that distance. You can quickly get excellent quality generator-grade extension cords.
Never place the generator near openings in the house, i.e., windows, doors, vents, etc.
Always turn the exhaust side of the generator away from the house. Wind direction plays a significant role here. If you can estimate the wind flow near your home, ensure the wind is not blowing exhaust air into your house.
Never use a generator in an enclosed environment such as a house, garage, or shed. Always make sure that the place where the generator is placed is well-ventilated.
You can choose the generator exhaust extension fitting system to send the exhaust gas from the generator to different places. This accessory is handy, especially when placing the generator near the house or inside the garage or shed. Even if you use a generator exhaust extension, ensure the exhaust pipes aren’t blowing those gasses anywhere near the house. If possible, try to divert the exhaust into the air higher up with the help of an extension tube.

Different generator manufacturers may have their recommendations for where to place the generator. Do proper research before installing a generator. This step is crucial, especially for backup generators, as they are more of a one-off and permanent installation.

By following these safety steps, you can confidently use your generator in an emergency.

Factors to Consider When Placing a Home Generator

Just like some considerations must be considered when shopping for portable and backup generators, some factors must be considered when placing a whole-house generator. We list some of them below.

Manufacturer’s recommendations

Some manufacturers give specific instructions for generator installation. You must keep this in mind when installing.

Generator size

The size of your whole house generator will determine how much noise you can expect to make and how much fuel you will need. Therefore, you must find a suitable installation location.

You also have to consider the size of the enclosure where the generator will be placed. You have to see if it can be placed on your property. Typically, larger-sized generators require large and thick concrete bases.

Local noise regulations

You must bear in mind the local noise regulations in your area. You must also follow homeowners association (HOA) rules when installing a whole-house generator.

Now the rules are different everywhere. What is acceptable in one region may not be so easy in another. Therefore, you must do thorough research and know the noise regulations that apply in your area. If your generator is too noisy, consider soundproofing it.

Applicable air quality regulations

Whole house generators usually require a permit before installation. Permits can only be granted if the individual demonstrates compliance with air quality regulations. It is vital to maintain these rules because generators emit carbon monoxide, which, if left unchecked, can undoubtedly affect human health.

Storage tank requirements

If you decide to run a whole-house generator with natural gas, you must consider the location of your existing utility lines. However, if you plan to use other fuels, you must use a storage tank, which is challenging in many ways.

Storage tanks come in various shapes and sizes, with varying capacities. Larger tanks have more extraordinary ability but require more space. It must be kept away from living areas to prevent explosions or fires, whether placed on the ground or underground.

Connection method

You must know how to hook up a generator to your home. It can be done with an extension cord or a transfer switch. An automatic transfer switch is the best option since you don’t need multiple wires. So it’s no hassle to lug multiple cables and run them through your home.

Local building codes

In addition to air quality regulations and local noise ordinances, local building codes must be followed. Local building codes include housing needs, local soils, climate, and more. So, be aware of building regulator regulations before installing a generator.

Required generator enclosure system

It is essential to have a whole-house generator enclosed within the structure. The enclosure you will build may be subject to its codes and rules, affecting the overall positioning and installation of generators throughout the house.

Some considerations for generators

While power outages are significantly more likely during cold, windy winter months and during rain (diesel generator running in rainy weather), you must be extra careful in these situations. Do not run the generator directly on rainy or windy days. The rain and low wind make it difficult for carbon monoxide gas to escape. If you must use the generator in such tricky weather conditions, use a tent-like structure to cover the generator while following all other safety precautions such as good ventilation, exhaust from the house, etc. Since carbon monoxide is a significant problem with portable generators, we recommend investing in a quality carbon monoxide detector, preferably a battery-operated one. Use these detectors in garages, near houses (within line of sight of generator and house), or even near generators. These devices are handy, primarily if you use your generator a little closer to the house or in your garage, shed, or basement. Some advanced modern portable generators have built-in carbon monoxide detection systems. These devices continuously monitor the level of carbon monoxide in the exhaust gas. If they detect critically elevated levels of carbon monoxide gas, shut down the generators. Check out these models and, if possible, invest in them.

Conclusion

After a massive storm, a power outage is the first thing that happens. A portable generator is one of the easiest and quickest ways to provide backup power. In addition to emergencies, you can use your portable generator in your camper, garage, or workplace. But always ensure you keep your generator safe from your home or RV to avoid the dangers of carbon monoxide.

FAQs

How far should my generator be from my camper?

Locate the generator as far away from your camper as possible, and make sure the exhaust is not facing your camper. If you park your camper at an RV or similar campground, watch for nearby campers and other generators. Don’t place it near someone else’s RV or blow exhaust into another camper. Have a friendly discussion with nearby campers and educate them on the hazards of carbon monoxide poisoning if they are unfamiliar. Watch for campfires, grills, gas tanks, and more. You should install carbon monoxide detectors in your RV. If possible, try to use shore power when you park your RV in a park or campground.

Is it safe to install a generator in the backyard?

Most people don’t realize that the closer a generator is to your house, the greater the danger it poses to your family.

Fumes from generators can be deadly, and you don’t want them seeping into your home.

Even if your generator is well-ventilated, you must consider the distance between the generator and the house.

The recommended distance is at least 20 feet, but even this may not be enough, depending on the size of the generator.

If you’re unsure, it’s still best to err on caution and keep the generator as far away from your house as possible.

Is it safe to use a generator indoors?

Generators can provide electricity during a power outage but can be dangerous if misused. Never use a generator inside the house or in partially enclosed areas such as garages, basements, porches, sheds, or in partially enclosed spaces such as garages or hallways.
