Best Generator For Long Term Power Outage FAQs

Can a generator be used indoors during a long-term power outage?

It is not recommended to use a generator indoors during a long-term power outage. Generators emit dangerous carbon monoxide (CO) gas which can be lethal if inhaled in large quantities. CO is a colorless, odorless gas that can cause symptoms such as headache, dizziness, weakness, nausea, and confusion. Prolonged exposure to CO can result in unconsciousness, brain damage, and even death.

To avoid the risk of CO poisoning, generators should only be used in well-ventilated outdoor areas, at least 20 feet away from any windows, doors, or vents. If you must use a generator indoors, it should be in a large, well-ventilated area, and a CO detector should be installed to monitor CO levels.

Additionally, it is crucial to have a backup plan for extended power outages, such as having extra fuel on hand or a backup generator if necessary, to ensure you have electricity during an extended outage.

How loud are generators during a long-term power outage?

The loudness of generators during a long-term power outage depends on the type of generator and its location. Portable generators are typically louder than standby generators, with noise levels ranging from 65 to 90 decibels (dB). However, newer models are designed to be quieter, with noise levels as low as 50 dB. Standby generators, on the other hand, are typically installed outside the home and are designed to be quieter, with noise levels ranging from 50 to 70 dB.

It's important to note that noise levels can also vary depending on the distance between the generator and your home. If the generator is located far away from your home, the noise levels will be lower than if it's located closer. Additionally, there are ways to reduce the noise levels of generators, such as placing them on a soundproof mat or building a soundproof enclosure around them.

Overall, while generators can be noisy during a long-term power outage, there are ways to mitigate the noise levels and make them more tolerable. It's important to research and choose a generator that meets your needs and noise level requirements.
