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.

Occupational health programs play a vital role in preventing occupational disease by shifting the focus from reactive treatment to proactive prevention. These programs utilize several key strategies to maintain a safe working environment:1

Environmental and Engineering Controls

Experts prioritize controlling hazards at the source. This includes:
* Engineering Solutions: Installing protective devices on machinery, improving ventilation to remove harmful dusts and vapors, and substituting toxic materials with safer alternatives.1
* Containment: If hazards cannot be eliminated, processes are contained to minimize worker exposure.1
* Personal Protection: As a final resort, workers are provided with protective equipment, such as respirators and specialized clothing.12

Monitoring and Surveillance

Occupational health specialists manage risk through:
* Environmental Monitoring: Measuring concentrations of toxic substances to establish and maintain safe exposure levels.3
* Medical Surveillance: Conducting pre-employment and periodic health examinations to monitor workers for signs of overexposure.14
* Targeted Supervision: Providing specialized medical advice and surveillance for vulnerable groups, such as pregnant women or those with disabilities, who may be more sensitive to environmental agents.5

By integrating these practices, organizations reduce absenteeism and improve overall worker welfare.1
