Asbestos is most dangerous when it becomes airborne in dust.
As dust, asbestos is easy to inhale, which is dangerous because when asbestos gets into the lungs it causes a form of lung cancer called asbestosis. There are many, very specific, laws that regulate how asbestos is removed, packaged and what landfills can accept the waste. Most asbestos problems are caused by improper removal. Only asbestos contractors that are licensed by the state of Illinois can legally remove asbestos. Anyone removing asbestos should wear an air mask with a separate air supply, wear a protective suit and gloves, and the asbestos should be wet at all time during the removal process.
