DH is a volunteer fireman and I have a family member that is a retired fire investigator. They both are adamant "Do not ever use an extension cord for anything" Although I do, I always use a cord far bigger than what I need for power. They mean in the house as well as out. Those little designer cords should be outlawed. Yesterday when we were in Tractor Supply, DH says, "What a fire hazard!" In the center of all the tanks of chicks were a dozen extension cords all over, plugged in to each other, going to the heat lamps for the chicks. My first thought was that the company was not being a very good example. I wonder how many go home and do the very same thing. I know everyone is worried about extension cords but keep in mind so many other factors can cause an electrical fire. If you blow fuses, maybe replace it once but if it happens again, there is a problem somewhere. Chicken dust is not good for us to breathe in and definitely not in a socket. I think electrical fires are the worst. They move fast. Don't be afraid, just be sensible.
