Asbestosis — occupational disease The lung disease asbestosis is caused primarily by prolonged inhalation of asbestos fibers. It occurs mainly among workers whose occupations involve exposure to asbestos and people who live near mines, factories, and construction sites.

Workplace safety programs must evolve alongside new materials and processes because industrial innovation frequently introduces previously unrecognized health risks. As workplace activities change, new forms of occupational injury and disease emerge, necessitating updated monitoring and protective strategies.1

The introduction of new substances often carries unforeseen toxicological consequences. For example, the historical use of beryllium in manufacturing led to severe lung conditions before its risks were fully understood, while the modern adoption of man-made mineral fibers and specific chemicals like toluene diisocyanate has required the implementation of new exposure standards to prevent occupational asthma and other respiratory illnesses.23

Furthermore, changes in technology and work environments—such as the shift toward intensive computer use—can lead to conditions like repetitive strain injury, requiring the application of ergonomics to mitigate physical harm. Because the nature of workplace hazards is dynamic, maintaining high safety standards is an ethical imperative to protect workers from preventable harm, ensuring that progress does not come at the cost of human health.1
