When the power goes out during a disaster or an emergency, you’ll be glad to have a portable generator in the house to come to the rescue. A portable generator is very useful to keep your lights, refrigerators, heaters, and other essential appliances running during a power outage. 

But before using a portable generator, you should know some essential generator safety tips to keep you and your family safe.

Did you know that portable generators produce poisonous and odorless carbon monoxide? You wouldn’t be able to notice it until you feel its effects. If you are exposed to carbon monoxide for a long time, you would need serious medical attention. 

According to a report, more than 900 people have died of carbon monoxide poisoning coming out of portable generators from 2005 to 2017. To avoid dangerous situations like this, we have compiled a list of safety rules to follow when installing and using a portable generator for your home. 

Portable Generator Safety Tips for Indoors

When you are using a portable generator to power the electrical appliances in your house or even your stick welder, follow these tips to ensure safety:

1. Keep Your Generator Outdoors

You should never keep generators confined in enclosed areas like your house or garage. Make sure the generator is at least 20 feet away from your house.

Because there’s no sufficient ventilation in confined areas (like inside your house), the CO will accumulate to dangerous levels.

Portable generators should be kept on the side of the house where there are no open windows or doorways. Doing so will keep the poisonous exhaust from seeping inside your home.

2. Install a Carbon Monoxide Detector

Since you can’t detect carbon monoxide until it is too late, it’s a good idea to install a detector. Carbon Monoxide detectors have an average price of $25, which is a good investment when you consider the safety and peace of mind you’ll get after installing it. 

3. Don’t Run a Generator when it is raining

Keep the generator dry at all times. Set up a small tent over it to keep it dry as well as well-ventilated during rainy seasons.

Never touch the generator with wet hands to avoid being electrocuted. 

4. Let it Cool Down Before Refueling

Generators run on gasoline which is highly flammable. Before you refuel the generator, you should turn it off and let it cool down for 3-4 minutes. If you don’t, the hot engine can ignite gasoline and cause serious damage.

5. Keep Additional Stock of Fuel supply

If you plan to use the portable generator for an extended period of time, you’ll need to keep an extra supply of gasoline or diesel on hand. When it comes to storing fuel, there are a few things to keep in mind.

You can learn more by reading this blog if you need to run a portable generator continuously for a longer duration of time. 

  • Keep the fuel in an ANSI-approved container.
  • Add chemicals or stabilizers if you need to store them for a longer time.
  • Keep the gasoline stock in a cool and dry place. 
  • Keep it away from any heat source in the house.

6. Avoid Back Feeding

Backfeeding is when the generator is plugged into a wall outlet or the main electrical panel to power the house. People who use electricity from the same utility transformer are at risk of electrocution as a result. It could also fry your electrical appliances and potentially cause a fire.

A licensed professional can connect the generator to the main electrical panel according to the proper codes. Make sure to install a transfer switch. A transfer switch eliminates the risk of using extension cords when disconnecting your home wiring.   

7. Portable Generator Maintenance 

This generator safety tips list would be incomplete without including some basic yet essential maintenance pointers that you should keep in mind.

  • Read the instructions in the user manual properly.
  • Store the generator in a safe area when you are not using it.
  • Keep the generator clean by removing gas, oil, snow, or grease. 
  • Inspect for leaks regularly on pipes, valves, and storage tanks. 
  • Hire a licensed professional to perform annual maintenance on your unit.

Portable Generator Safety Tips for the Go

For travelers who are always on the go, the same rules apply. However, there are a few things you need to be more careful of:

8.Check the Generator Exhaust

Before each use, double-check that your generator’s exhaust isn’t leaking. Keep an ear out for any unusual exhaust noises. And make sure the exhaust is facing away from where you’re camping.

If you’re suddenly feeling dizzy, shut off the portable generator and step outside to get some fresh air. Before sleeping, turn off the generator and keep the windows open to allow fresh air to come in. 

9. Install Alarms 

Install a carbon monoxide and fire alarm in your RV. Check that they are in working order and replace the batteries if necessary. Install the smoke alarm near where you sleep in the RV.

Make sure to replace the batteries before your trip. You might need to install more than one alarm depending on the size of your RV. 

10. Use Heaters inside RV Safely

If you’re going to use portable heaters, barbecues, stoves, or even kerosene lamps, make sure you do so outside the RV. Keep windows open even if you’re using the stove to ensure proper ventilation.

When using electrical appliances inside the RV, keep an eye on them. If you become dizzy, turn off the appliances and exit the RV immediately, leaving the windows and doors open to allow carbon monoxide to escape.
