I usually just ignore the asbestos unless it's falling apart and has become useless. Unless you do something stupid like grind it up and snort it like a certain drug that Rick James used to use, you have a greater risk of something happening while crossing the street. One way to deal with it, if it's a concern, is to encapsulate it with latex paint, it will soak into it and prevent it from coming apart.
