You've described a no-risk situation. That is trivial damage and has not released any fibers of concern. There is already asbestos floating around in the air in any urban and even rural environment...it's called a background level. If you were to have done air monitoring in your home at any time the past several years, and fibers were detected, they would likely have been due to background levels from other sources than your home.

You are right to be concerned about asbestos in your environment, but you are blowing this way out of proportion. When you get test results back, they may identify asbestos, and all that means is that you shouldn't tear it all out. We have all lived around asbestos all out lives...home, work, and school. The reality is that your exposure, such as it is, is no different from the rest of your community, but you don't see hordes of them dying from asbestos-caused cancer, do you?

I worked a good part of my career for a federal environmental agency, and for many of those years managed the asbestos program for the office. I can't begin to tell you how many people I talked to who called with exactly your concerns. They knew enough about asbestos to have scared themselves, but did not have the risk assessment background to put it in perspective. Yes, I did talk with people who had created health risks for their families by dry-scraping asbestos-containing popcorn ceilings, or removing massive amounts of asbestos-containing insulation from their furnaces, or sanding down asbestos-containing flooring during a remodel, etc., and they were right to be concerned. But a large number of people were like you: they were deeply afraid simply because they discovered asbestos was in their homes, and thought it was a ticking timebomb. The tiny amount of damage you describe is in the noise level.

If you want to protect yourself and your family, make sure you all wear seat belts when you are driving, that none of you smoke, that you maintain a healthy diet, and have the kids look both ways when they cross the street: that will take care of 99.9% of the risk that life poses. And finally, quit worrying: the stress you are unnecessarily subjecting yourself to is the only health risk I am seeing here.
