3. Chemical diseases or chemical hazard
4. Diseases due to unusual timings/shift workers.

Here, we are discussing general occupational disease:
1. Diseases due to physical agents/physical hazards:
Diseases which are occurred due to physical condition of the working places e.g. a high and low temperature falls under this category. Many industrial worker who are working under extremely heat temperature like mine and furnaces may face bum, cramps, exertion etc. and such type of physical problems. Those who are working under extremely cold temperature may face frost bite, trench foot etc. There are few basic physical agents which creates health hazard are as ahead:

(a) Light:
High light and low light can cause eye sight problem. Working in high light can cause mental fatigue and working under low light conditions can cause mental stress, heaviness on eyes, headache etc.

(b) Noise: Working under severe noise or listen loud sound for long time can cause hearing loss, headache, stress etc.

(c) Radiation:
Radiation damage to the intestinal tract lining will cause nausea, bloody vomiting and diarrohea. Long-term health effects of radiation can be cancer and cardiovascular disease.

2. Dust diseases/dust hazards: There are so many lung diseases which are occurred due to accumulation of dust, most common dust diseases are as follow:

(a) Coal dust The disease named black lung disease is caused by inhaling coal dust. It causes inflammation and scarring of the lungs. This can cause permanent lung damage and shortness of breath.

(b) Silica dust This condition is caused by breathing in silica crystals in the dust of mines. It causes scarrying of the lungs. It can also increase the risk for other lung diseases.

(c) Cotton dust/Byssinosis:
It is also known as Brown Lung Disease. This is caused by breathing in dust from hemp, flax, and cotton processing. The condition is chronic and causes chest tightness and shortness of breath. It affects textile workers, especially those who work with unprocessed cotton.

(d) Occupation Asthma:
Occupational asthma is caused by breathing in dusts, gases, fumes, and vapours. It causes asthma symptoms such as a chronic cough and wheezing.

3. Chemical diseases/Chemical hazards:
Chemicals are used extensively both in industry and in our daily lives. Many useful products are derived from chemicals, such as plastics, paints, pharmaceuticals, detergents etc. some chemicals may appear harmful only after prolonged exposure. These diseases include diabetes, allergies, asthma; eczema, cancer, attention deficit disorder, autism, learning difficulties, infertility, depression, chronic fatigue, chemical sensitivities, heart disease, multiple sclerosis, Parkinson’s disease, thyroid disease, inflammatory bowel disease amongst many others. There are few chemical hazards which cause death. They are as follow:

(a) Diseases Caused due to Inhalation of Poisonous Gases:
Many types of gases such as chlorine, phosgene, sulphurdioxide, hydrogen sulphide, nitrogen dioxide, and ammonia may suddenly be released during industrial accidents and may severely irritate the lungs. Gases such as chlorine and ammonia easily dissolve and immediately irritate the mouth, nose, and throat.

(b) Lead Poisoning: By swallowing tiny particles of lead, a worker may face constipation abdominal colic, anaemia, pain in muscles etc.

(c) Mercury poisoning: The ingestion of mercury may cause breathlessness, swelling of gums, falling of teeth, anaemia etc.

4. Diseases due to unusual timings/shift workers:
In today’s scenario due to technological development in the world, it has been noticed that most of the IT companies are coming into existence as a job opportunity. These companies provide jobs in Indian scenario at night or evening shifts due to time difference of countries like USA and Australia etc. So, the workers who are working in night shifts usually falls prey to diseases like lifestyle diseases, e.g. diabetes, hypertension, insomnia, lack of sleep (sleep deprivation) and improper dietary habits etc. So, this is also an occupation related disease which is caused due to unusual timings and work hour shift etc.

Question 4.
Define the term disability. Also elucidate various preventive measure of disability.
Answer:
Disability means inability to do certain physical or mental work. When the capacity to perform any physical or mental work decreases that stage is called disability. According to W.H.O., “Disability is a restriction or lack of ability to perform an activity in the manner or whithin the range considered normal for a human being.”
Any abnormal condition of the body whether congenital or acquired may be called disability.

Preventive Measures of Occupational Disability:

The aim of occupational health is to promote and maintain the well being of workers in all occupations. To keep the workers physically, mentally, socially and emotionally fit, some preventive measures are adopted which can prevent many occupational diseases. Many disabilities occur due to the occupational environment. Occupational hazards are more common, where the workers do not follow principles of occupational hazards. The following preventive methods should be followed to minimize the occupational health hazards:

1. Medical examination before joining:
The purpose of this examination is to place the right man in the right job. A person should be given job only when he is found medically fit so that he can perform his work efficiently without any danger e.g. a person suffering from asthma should be rejected at the time of employment in mining industry.

2. Periodical examination of workers:
Since many occupational diseases take long time to develop, it is difficult to recognise them at an early stage. If a disease is detected at initial stage, it can be cured easily and quickly. The purpose of this examination is to detect and cure the disease at an early stage. The frequency of examination depends upon type of occupational exposure. Monthly examination is preferred.

3. Maintenance of work places:
Many occupational diseases arise due to physical agents like light, heat, cold, pressure radiation, noise, etc. Therefore, special attention should be given for the maintenance of these physical agents. The physician should check and maintain temperature, light, ventilation, humidity, noise etc.
The following steps should be taken in the supervision of working places:

(a) Control of Air pollution:
Most of the diseases arise due to air pollution. It should be controlled by adopting following methods:

(i) By Increasing Humidity: Dust can be controlled by increasing humidity because dust floats more in dry air. By spraying water at working places, air pollution can be controlled. Even while grinding little moisture is added to the material to prevent air pollution.

(ii) Separate Enclosure: The harmful material should be enclosed separately to prevent the escape of dust and fumes in the factory.

(iii) Exhaust Ventilation: Proper exhaust ventilation should be provided in the factory, so that toxic fumes can be exhausted out.

(b) Control of Noise Pollution:
Occupational deafness is caused due to excessive noise in the factory. The noise can be reduced by noise absorbing ceilings and walls. Even carpet flooring also helps in reducing noise pollution.

(c) Control of fflumination:
There should be proper light at the working places in the factory so that diseases arising due to poor or high illumination can be avoided.

(d) Temperature Control:
Some occupational health hazards are caused due to excessive heat or cold. It can be avoided by regulating the temperature of the working places.

4. Use of Protective Devices:
Many occupational health hazards can be prevented by the correct use of protective devices. For example, the use of gas masks can prevent the respiratory disabilities which are caused due to inhalation of chemical agents like dust, gases, etc. The use of many protective devices like ear-plugs, shoes, gloves, aprons, helmets, etc. can prevent various occupational health hazards.

5. Mechanisation of Plants and Factories:
The mechanisation of the factories can reduce the hazards of stress and strain as heavy lifting can be done by mechanical devices. Even Contact with harmful substances can be prevented by the use of mechanical devices.

6. Maintenance of Health records:
It is very important to run an efficient occupational health service. Health record of the worker should be maintained periodically which will be helpful in assessing the health conditions of the workers.

7. Educating the Workers:
Many occupational hazards occur in the workers due to lack of education. Each worker should be taught about the correct use of protective devices. Workers must be instructed about the correct use of machines, which can avoid the accidents in the factories. All the risks involved in the occupational environment should be made clear to each worker for his safety.

8. Periodical Examination of Machines:
Many accidents occur in the factories due to fault in the machines. The aim of the periodical check up of the machines is to avoid these accidents by repairing and replacing the defective machines.

9. Prohibition of Intoxicants:
Sometimes individuals are themselves responsible for occurrence of disability due to consuming intoxicants. Therefore use of intoxicants should be strictly prohibited at the working places.
By keeping all the above mentioned points in mind a worker can lead happy occupational life.
