1) It is an offense to dispose of asbestos in most locals outside of a hazardous site.Definately illegal to dispose in a government landfill.

2) you can contaminate others from your clothes hair etc (it stays around).

3) Many pros say a resparator offers the best protection for workers. They tape around masks to ensure the small particles do not enter airways around the seal (as with mold).Water is sprayed in the sourrounding air to reduce airborne particles. This concentrates the material on the ground (where it still can impact people, if it gets airborne or on clothes). They use plastic taped around outside surfaces to contain and double bag in thick plastic bags. If particles get in your house,, they get airborne later (i.e. clothes, fans, vacume cleaner)

4) It may cost to hire a pro. It depends on how much you value your health and life?
