Help! My ceiling collapsed last night. I sealed off the affected area and my family is living in another area of the house. I need advise on how to minimize exposure to asbestos dust in our new alternate living area as the central air unit continues to carry these culprit dust particles all over the house. Do you suggest I humidifiers to keep the dust down? Also, how should I approach cleanup in the this new alternate living area where I can't see all the dust? Should I do it myself, or just leave it to a professional company?
