Place the generator in a well-ventilated area 

You should place the generator in a well-ventilated area. You know, the generator produces carbon monoxide gas that is extremely harmful to animals.

Keep the generator on a dry and plain land 

Don’t keep your generator on the wet grass field. It produces electricity. So you should be careful about electricity. 

Refuel Engine

If you are an owner of a generator, you could attach a transfer switch inside of your house. you could hire a licensed electrician. Yes, it may cost you. but it is safe for you and your neighbors. 

A portable generator could be dangerous if you don’t use a transfer switch to use the heavy appliance with induction electrical motors. 

Bottom line 

Last but not least, a generator will not damage your refrigerator or other household appliances. You just make sure that you are using them in the right way. 

Don’t feel hesitant to get a generator for a disaster or blackout. When the hurricane comes, you will not find a generator in the local store. It would be better to prepare for the electricity outage.
