DEFINATION OF AGRICULTURE
IAOH - 2013 3
INTRODUCTION
An estimated 1.3 billion workers are engaged in
agricultural production worldwide. This represents
half of the total world labour force.
Almost 60% of them are in developing countries.
A great majority of agricultural workers are found
in Asia, which is the most densely populated
region of the world, with more than 40% of the
world's agricultural population concentrated in
China and more than 20% in India.
IAOH - 2013 4
SPECIFIC FEATURES OF AGRICULTURE
most tasks are carried out in the open air,
exposing workers to climatic conditions;
the seasonal nature of the work and the
urgency of certain tasks in specific periods;
a wide variety of tasks are performed by the
same person;
the type of working postures and the length
of the tasks performed;
IAOH - 2013 5
contact with animals and plants exposing
workers to bites, poisoning, infections,
parasitic diseases, allergies, toxicity and other
health problems;
the use of chemicals and biological products ;
the considerable distances between living
quarters and workplaces.
SPECIFIC FEATURES OF AGRICULTURAL WORK
IAOH - 2013 6
LABOUR FORCE IN AGRICULTURE
Lack of clear-cut distinctions between
different categories of workers.
Numerous types of labour relations and
different forms of labour force
participation.
IAOH - 2013 7
PRINCIPLES OF BOHS
The following principles will be applied in the
organization of Basic Occupational Health
Services:
Available to all working people
Addressing to local needs
Adapted to local conditions
Affordable to providers and clients
Organized by the employer for employees
Provided by the public sector for the self-
employed and the informal sector
Supported by intermediate level services
IAOH - 2013 8
BOHS MODEL
IAOH - 2013 9
ORIENTATION AND PLANNING
1. Analysis of the type of production indicating the risks
and problems typical of the branch or occupation in
concern.
Agriculture involves a wide range of different types of
machinery, animals, plants and products, working in
both indoor and outdoor environments
In India labour-intensive farming is much more common.
2. Review of problems that have been identified previously
in the company
3. Review of the characteristics of the workforce of the
company
child labour , migrant workers , seasonal, migratory and
casual labour.
IAOH - 2013 10
ORIENTATION AND PLANNING
4. Available data on occupational diseases and
accidents
5. Data on working methods, chemical substances,
etc.
6. The knowledge by employers and employees of
occupational health problems
7. Plans for changes in production systems, e.g.
installation of new facilities, machinery and
equipment
IAOH - 2013 11
SURVEILLANCE OF THE WORK ENVIRONMENT
1. Identification and evaluation of ergonomic factors which may
affect the workers' health
Ergonomic factors affecting the health outcomes of agricultural
workers include:
the nature of the physical work environment (noise, heat,
lighting, thermal comfort), the agricultural tasks to be
performed;
the technology applied to the prescribed tasks (including
workplace design, facility design, and agricultural material
handling);
the manner in which tasks are organized (including use of
shift work); and
Worker characteristics (including demographics, physiology,
human error, and identification and treatment of injured
workers).
IAOH - 2013 12
SURVEILLANCE OF THE WORK ENVIRONMENT
2. Assessment of conditions of occupational hygiene and
factors,
such as physical, chemical, and biological exposures which may
generate risks to the health of workers
2. Assessment, where appropriate, of exposure of workers to
adverse psychological factors and aspects of work
organization
3. Assessment of risk of occupational accidents and major
hazards
4. Assessment of collective and personal protective equipment
5. Assessment of control systems designed to eliminate, prevent
or reduce exposure
6. Assessment of general hygiene and sanitary facilities

IAOH - 2013 16
SURVEILLANCE OF WORKERS' HEALTH
The following types of health examinations are carried
out either on the basis of regulations or as a part of good
occupational health practice:
1. Pre-assignment (pre-employment) health examinations
2. Periodic health examinations
3. Return to work health examinations
4. General health examinations
5. Health examinations at termination or after ending of
service
A new type of health examination has recently been
introduced for assessment of work ability of ageing
workers.
IAOH - 2013 17
SURVEILLANCE OF WORKERS' HEALTH
In the case of exposure of workers to specific hazards,
medical and health surveillance should include, where
appropriate, any examination and investigations which
may be necessary to detect exposure levels and early
effects and responses which also bear in mind the
biological difference between women and men.
Example, in pesticide handlers.
Pre-employment screening should ensure that those with
inherently low-level cholinesterase do not undertake
work with organophosphate or carbamate pesticides
baseline samples, periodic samples,
IAOH - 2013 18
ASSESSMENT OF HEALTH AND SAFETY RISKS
A “hazard” is anything with the potential to do harm,
whereas a “risk” is the likelihood of potential harm from
that hazard being realised.
The identification of hazards in the workplace should
take into account:
(a) the situation or events or combination of
circumstances that have the potential to give rise to
injury or illness;
(b) the nature of potential injury or illness relevant to
the activity, product or service;
(c) those likely to be harmed (e.g. young workers, older
workers, temporary workers, pregnant workers); and
(d) past injuries, incidents and illness.
IAOH - 2013 19
ASSESSMENT OF HEALTH AND SAFETY RISKS
The steps in an occupational health risk assessment include:1.Identification of occupational health hazards (as a result of surveillances)
Hazards Description
Mechanical hazard
Poorly designed and/or guarded agricultural machinery is a major cause of fatalities and accidents. Injuries from cutting tools are another major risk.
Psycho social hazards
low pay, sexual and other harassment, job insecurity, poor promotion mechanisms, delay in payment of salaries.
Work organisation hazards
badly organised shift work and working hours, excessive overtime, lone working, lack of control over work.
Ergonomic hazards
These hazards can cause permanent injuries and disablement. For example: badly designed machinery, prolonged static working positions, repetitive work, unsuitable tools used by workers, poor seating
Others - Physical hazards , Biological hazards, chemical hazards, environmental
IAOH - 2013 20
ASSESSMENT OF HEALTH AND SAFETY RISKS
2. Identification of workers or groups of workers
exposed to specific hazards for e.g. in tea
plantation workers the hazards are different for
pruners, pluckers, sprayers
3. Analysis of how the hazard may affect the worker
(ways of entry and type of exposure, threshold
limit values, dosage/ response relationships,
adverse health effects it may cause, etc.in case of
sprayers who are in constant contact with the
pesticides)
4. Determination of intensity (level) and magnitude
(volume) of risk
IAOH - 2013 21
ASSESSMENT OF HEALTH AND SAFETY RISKS
5. Identification of individuals and groups with
special vulnerabilities, e.g. young workers, old
workers, pregnant workers, temporary workers
6. Evaluation of available hazard prevention and
control measures
7. Making conclusions and recommendations for the
management and control of risks
IAOH - 2013 22
ASSESSMENT OF HEALTH AND SAFETY RISKS
Hierarchy of control measures for reducing risks in the
work place.
A.Elimination
B.Substitution
C.Others
technical and engineering control- enclosure,
isolation, ventilation
Safe systems of work- changing work schedules,
extending rest periods, training and information
Issuing Personal Protective Equipment (PPE)
8. Documenting the findings of the assessment
9. Periodic review and, if necessary, reassessment of risks
IAOH - 2013 23
INFORMATION AND EDUCATION ON RISKS AND ADVICE ON THE NEED FOR PREVENTIVE
AND CONTROL ACTIONS
The information and education include the following
aspects:
1.Workers in agriculture should have the right to be
informed and consulted on OSH matters including risks
from new technologies; and
2.The workers have a right to know and get continuously
information on hazards related to their own work and the
workplace.
3.The employer is responsible for training the workers on
safe and healthy work practices.
IAOH - 2013 24
4. The workers have a duty to follow the safety
instructions and safe and healthy work practices.
5. Confidential health information of an individual
worker is subject to special legislation and practices
and to informed consent.
6. The advice provided by OHS personnel must be
given in a form which is easily understood by
employers and workers.
7. Information given to various partners should be
documented.
INFORMATION AND EDUCATION ON RISKS AND ADVICE ON THE NEED FOR PREVENTIVE
AND CONTROL ACTIONS
IAOH - 2013 25
PREVENTIVE ACTIONS FOR THE MANAGEMENT AND CONTROL OF HEALTH AND SAFETY
HAZARDS AND RISKS
Control measures should be monitored and
reviewed at regular intervals and if necessary
revised, especially when circumstances change or
if new information becomes available about the
risks posed or the suitability of existing control
measures.
Control measures should also be reviewed and if
necessary revised following an accident.
IAOH - 2013 26
The risk management actions may comprise:
• Control of hazards at the source
• Ventilation or control technology
• Dust control
• Ergonomic measures
• Use of personal protective equipment
• Regulation of thermal conditions, etc.

HAZARDS AND RISKS
IAOH - 2013 27
PREVENTION OF ACCIDENTS
1. Safe planning of facilities, machinery, etc.
The employer should not permit the use of any
unsafe or faulty equipment.
The employer should ensure the provision of
adequate information, instruction and training
for those using equipment, and that their skill
levels are periodically evaluated.
2. Good housekeeping, order and cleanliness
The employer should ensure that workers are
clearly instructed and supervised in good
housekeeping measures that can prevent slips,
trips and falls.

3. Making walkways and other structures safe (e.g.
scaffolds, fences)
The employer shall ensure that: walking surfaces
and stairs inside facilities are equipped with
adequate lighting; stairs and ladders are maintained
in good condition with handrails in place; .
4. Guarding dangerous machines- by providing
enclosures, safety symbols surrounding such places.
Unauthorized persons should not be allowed to
operate machinery. In particular, children should be
kept away from all agricultural equipment.
PREVENTION OF ACCIDENTS
IAOH - 2013 29
5. Technical aids for moving and lifting heavy loads
With regard to the use and maintenance of ladders,
the employer should ensure that appropriate, well-
maintained equipment is available and is
appropriate to the task at hand. the use of
mechanical means to lift or lower heavy objects;
and other practices appropriate to the task at hand.
6. Safe tools and safety equipment for workers
Workers should use handholds when mounting and
dismounting equipment.
