The first safety thing I would teach my kids, is calling 911, show them on the phone were it is located at, just encase something happens when there is no other grow up person around them, then tell them to never answer the door, unless you ask who is it, then have them go tell someone in the house who it is, and let them opened the door, third thing is show them in the house, to not touch chemicals, it can hurt you, ect.
