Environmental Health & Safety General Asbestos Awareness: Online Training



Lung tissue becomes physically scarred by asbestos fibers, which impair the elasticity of the lung and hamper its ability to exchange gases. This scarring leads to inadequate oxygen intake by the blood.

Scarring restricts lung expansion during inhalation. This leads to decreased lung volume and increased resistance in the airways.

Asbestosis is caused by very high exposures (high dose).

Asbestosis is a slowly progressive disease with a latency period of 15 to 30 years.

Since asbestos fibers remain in the lung, damage continues even after exposure
