Luca just learned about the dangers of asbestos and wants to educate others about this pollutant. What advice should he share to
solong [1392]

Response: D: Always wear safety equipment when handling home insulation.

Justification: Exposure to any level of asbestos is unsafe; inhalation of even tiny asbestos fibers can cause the build-up of fibrous tissue known as asbestosis, leading to impaired lung function, disability, and ultimately mortality.

2. It can also be a cause of lung cancer.

3. It can lead to mesothelioma affecting the lungs.

Workers have the right to be informed about the dangers posed by asbestos and must receive appropriate safety gear when working with home insulation, considering that no level of "safe" exposure to asbestos fibers exists.

Asbestos types include:

1. Chrysotile

2. Amosite

3. Crocidolite

4. Tremolite

5. Anthophyllite

6. Actinolite

Or any chemically treated variant of these.
