Identifying the presence of asbestos -containing materials (ACMs) within your home may be difficult, especially only by a mere sight. Furthermore, the only way to be sure is by having a sample of the suspected materials analyzed by a certified laboratory. A DIY attempt on collecting the samples can be dangerous cause you may damage the ACM itself and release hazardous materials to the air. That is why the government stated that only a qualified and certified person can do the removal job.
