Amphibole asbestos has needle-shaped fibers. Studies suggest it takes much less exposure to amphibole asbestos to cause cancer, compared to serpentine asbestos. Amosite and crocidolite are the most commercially valuable types of amphibole asbestos, while anthophyllite, tremolite and actinolite are considered noncommercial forms

Jul 15, 2021 Asbestos fibers must be airborne to cause a health risk through inhalation, so the first step is not to disturb the material, which would release more fibers into the air. If you remove or disturb the insulation, it is probable that you may inhale some asbestos fibers - the degree of health risk depends on how much and how often this occurred
