Solution:The correct associations between occupational diseases and their particulars, as given in the options, are as follows:
(a) Anthrax: This disease is commonly associated with animal handling, especially those who work with livestock or animal products that might be contaminated. Anthrax is a wellknown occupational hazard in industries dealing with wool, leather, and other animal products, making IV. Disease of animals the appropriate match. Anthrax is an infectious disease caused by the bacterium Bacillus anthracis, predominantly found in agricultural settings.
(b) Silicosis: This is an occupational lung disease caused by the inhalation of crystalline silica dust. It is prevalent among workers involved in occupations such as mining, quarrying, and sandblasting. Therefore, III. Caused by inhaling dust containing silica is the correct pairing. Silicosis leads to inflammation and scarring in the lungs, severely affecting respiratory function over time.
(c) Asbestosis: Asbestosis is a chronic lung disease caused by inhaling asbestos fibers, which leads to the development of fibrous scar tissue inside the lungs. This condition reduces the lung's ability to exchange gases and is primarily observed in industries related to asbestos, such as during the manufacturing of asbestos products like mattresses. Hence, II. Making of asbestos mattresses is the right match for asbestosis, reflecting direct exposure to asbestos in the workplace.
(d) Telegraphic Cramp: This occupational disease is associated with repetitive tasks that involve the hands and arms, traditionally seen in telegraph operators who used Morse codes for long periods. The symptoms include cramps and pains, which are primarily due to the repetitive nature of the task requiring high levels of accuracy, speed, and concentration. Thus, I. Degree of accuracy, speed of work and concentration required for the job accurately corresponds to telegraphic cramp, highlighting the strain put on muscles during repetitive motions.
The correct answer, therefore, is C: IV, III, II, I, which directly links each occupational disease to its characteristic workplace hazard or the nature of the job that predominantly leads to the disease. This accurate matching underscores the specific conditions and exposures associated with each occupational disease.
