Occupational diseases are the result from long term employment in a particular type of work. Black lung disease among miners, cancer among asbestos installers, Pneumoconioses and Metallic fever are such occupational diseases.
This disease is caused due to exposure to particles of carbon. When coal dust is inhaled for a long period of time, it builds up in the lungs, which the body is not able to remove, inflammation of the lungs causes large size cavities in the lungs.
Pneumoconiosis/Chronic lung disease is caused due to the inhalation of various forms of dust particles, particularly in industrial workplaces for an extended period of time. Shortness of breath, wheezing and chronic cough are some of the symptoms.
Asbestosis is Scarring and thickening of the lung tissue. Exposure to asbestos dust causes Asbestosis. Scars continue to grow and prevents oxygen supply to the lung, causing increasing difficulty in breathing. Unless it can be surgically removed very early, it tends to spread by blood and lymph and lead to early death.
We can prevent these diseases by periodic examinations, preplacement examinations, working supervision and health education. Engineering measures such as proper design of plant, ventilation, dust isolation through enclosure and isolation and protective devices.
Hope this article arises awareness towards occupational diseases.
