1. Again, you might not have any of these around your house, but it probably wouldn't be a bad idea to have one or two.
2. Many businesses use them as well.
3. In a home, they would probably be used outdoors. In a business, they'd use them outdoors, but some businesses use them indoors as well for the purpose of saving money.
