Occupational health:The objective of an occupational health .LalrinchhaniSailo
Occupational health is essentially preventive medicine.The Joint ILO/WHO Committee on Occupational Health, in the course of its first session, held in 1950, gave the following definition: "Occupational health should aim at the promotion and maintenance of the highest degree of physical, mental and social well-being of workers in all occupations; the prevention among workers of departures from health caused by their working conditions; the protection of workers in their employment from risks resulting from factors adverse to health; the placing and maintenance of the worker in an occupational environment adapted to his physiological and psychological equipment, and, to summarize, the adaptation of work to man and of each man to his job (1).
ERGONOMICS: The term "ergonomics" is derived from the Greek ergon, meaning work and nomos, meaning law. It simply means: "fitting the job to the worker". The object of ergonomics is "to achieve the best mutual adjustment of man and his work, for the improvement of human efficiency and well-being".
HEALTH OF THE WORKER
One of the declared aims of occupational health is to provide a safe occupational environment' in order to safeguard the health of the workers and to step up industrial production.
Occupational environment
By occupational environment is meant the sum or external conditions and influences which prevail at the place of work and which have a bearing on the health of the Working population. Basically, there are three types of interaction in a working environment.
a) Man and physical, chemical and biological agents.
b) Man and machine.
c) Man and man.
MAN AND PHYSICAL, CHEMICAL AND BIOLOGICAL AGENTS
(1) Physical agents
(2) Chemical agents
MAN AND MACHINE
An industry or factory implies the use of machines driven by power with emphasis on mass production. The
unguarded machines, protruding and moving parts, poor installation of the plant, lack of safety measures are the causes of accidents which is a major problem in industries.
Working for long hours in unphysiological postures is the cause of fatigue, backache, diseases of joints and muscles and impairment of the worker's health and efficiency.
MAN AND MAN
There are numerous psychosocial factors which operate at the place of work. These are the human relationships amongst workers themselves on the one hand, and those in authority over them on the other. In modern occupational health, the emphasis is upon the people, the conditions in which they live and work, their hopes and fears and their attitudes towards their job, their fellow-workers and employers (2).
OCCUPATIONAL HAZARDS
An industrial worker may be exposed to five types of hazards, depending upon his occupation:
1. Physical hazards
2. Chemical hazards
3. Biological hazards
4. Mechanical hazards
5. Psychosocial hazards.

Occupational health and occupational hazards by Dr. Sonam AggarwalDr. Sonam Aggarwal
• "Occupational health should aim at the promotion and maintenance of the highest degree of physical, mental and social well-being of workers in all occupations;
• the prevention among workers of departures from health caused by their working conditions;
• the protection of workers in their employment from risks resulting from factors adverse to health;

MBBS UG class on occupational health in three parts. part 1 includes introduction of occupational health, occupational diseases, ergonomics and Pneumoconiosis
An occupational hazard is a hazard experienced in the workplace. Occupational hazards can encompass many types of hazards, including chemical hazards, biological hazards (biohazards), psychosocial hazards, and physical hazards. In the United States, the National Institute for Occupational Safety and Health (NIOSH) conduct workplace investigations and research addressing workplace health and safety hazards resulting in guidelines. The Occupational Safety and Health Administration (OSHA) establishes enforceable standards to prevent workplace injuries and illnesses.
Occupational hazards, occupational health
Occupational safety and health should not be sidelined as a service delivery issue. Health worker health and well-being is an important aspect of workers’ motivation and job satisfaction, which influence productivity as well as retention. Health worker safety also affects the quality of care; caring for the caregiver should be a priority area of concern for the health system’s performance.

• Preventive medicine & Occupational health-
1. Levels of application of preventive measures
2. Tools
• Occupational health is therefore application of
preventive medicine in all places of
employment.
9.
10. Ergonomics
• It is derived from Greek term-
a. Ergon means ‘work’
b. Nomos means ‘law’
• It simply means-
‘ fitting the job to the worker’
11. Ergonomics
• The International Ergonomics Association defines ergonomics
or human factors as follows:
• “Ergonomics is the scientific discipline concerned with the
understanding of interactions among humans and other
elements of a system, and the profession that applies theory,
principles, data and methods to design to optimize human
well-being and overall system performance.”
12. Training in Ergonomics involves-
Designing of machines, tools, equipment and
manufacturing processes
Lay-out of places of work
Methods of work and environment-
-in order to achieve greater efficiency of both
man and machine.
13. Objective of ergonomics
• To achieve best mutual adjustment of
man and his work, for the improvement
of human efficiency and well-being.
14. The Benefits of an Ergonomic Program
• Decreased injuries, illnesses, and workers’
compensation costs.
• Decreased absenteeism .
• Increased physical well being.
• Increased efficiency at work.
15. Occupational environment
Definition:
“It means the sum of external conditions
and influences which prevail at the place of
work and which have a bearing on the health
of the working population.”
19. Heat & cold
• Work of Rao & Mookerji et al. (1953) indicate
Corrected effective temperature of 69 to 80
deg. F (20 to 27 deg. C) is the comfort zone in
this country.
• Burn, Heat exhaustion, Heat stroke, Heat
cramps
27. U v radiation
• Mainly in Arc welding
• Affects eyes, causing intense conjunctivitis
and keratitis causing Welder’s flash.
28. Ionizing radiation
• Important radio-isotopes are:
1. Cobalt 60
2. Phosphorus 32
• Hazards caused are- genetic changes,
malformation, cancer, leukemia, ulceration,
sterility
• International Commission of Radiological
Protection has set maximum permissible level
of occupational exposure at 5 rem per year to
whole body.
33. Occupational Diseases
• Occupational diseases have a long latent
period.
• Most occupational diseases cannot be treated.
• All occupational diseases can be prevented.
35. pneumoconiosis
• Dust within the size range of 0.5 to 3 micron is a
health hazard producing.
• The hazardous effect of dust on lung depends upon
number of factors-
1. Chemical composition
2. Fineness
3. Concentration of dust in air
4. Period of exposure
5. Health status of person exposed
36. 1. silicosis
- Free silica or silicon dioxide (SiO2)

43.
44. 6. farmer’s lung
• Inhalation of mouldy hay or grain dust
• Bacteria and fungi grow rapidly if moisture content is
> 30 % causing rise of temperature to 40-50 deg. C
• This leads to growth of thermophilic actinomycetes-
Micropolyspora faeni
• Later stages- pulmonary fibrosis, inevitable
pulmonary damage & cor pulmonale
