1. Occupational safety and health in agriculture- The BOHS approach BOHS series

2. Definition of agriculture Agricultural and forestry activities carried out in agricultural undertakings including • Crop production, forestry activities, animal husbandry and insect raising, the primary processing of agricultural and animal products by or on behalf of the operator of the undertaking. • As well as the use and maintenance of machinery, equipment, appliances, tools, and agricultural installations, including any process, storage, operation or transportation in an agricultural undertaking, which are directly related to agricultural production. REF: ILO convention no. 184

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.

4. Specific features of agricultural work • 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; • 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.

5. 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.

6. 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

7. BOHS MODEL

8. ORIENTATION AND PLANNING • 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. • Review of problems that have been identified previously in the company • Review of the characteristics of the workforce of the company • child labour , migrant workers , seasonal, migratory and casual labour.

9. ORIENTATION AND PLANNING • Available data on occupational diseases and accidents • Data on working methods, chemical substances, etc. • The knowledge by employers and employees of occupational health problems • Plans for changes in production systems, e.g. installation of new facilities, machinery and equipment

10. SURVEILLANCE OF THE WORK ENVIRONMENT • 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).

11. SURVEILLANCE OF THE WORK ENVIRONMENT • Assessment of conditions of occupational hygiene and factors, such as physical, chemical, and biological exposures which may generate risks to the health of workers • Assessment, where appropriate, of exposure of workers to adverse psychological factors and aspects of work organization • Assessment of risk of occupational accidents and major hazards • Assessment of collective and personal protective equipment • Assessment of control systems designed to eliminate, prevent or reduce exposure • Assessment of general hygiene and sanitary facilities

13. Occupational Health Problems in Agriculture

14. 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.

15. 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,

16. 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.

17. ASSESSMENT OF HEALTH AND SAFETY RISKS The steps in an occupational health risk assessment include: • Identification of occupational health hazards (as a result of surveillances)

18. ASSESSMENT OF HEALTH AND SAFETY RISKS • 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 • 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) • Determination of intensity (level) and magnitude (volume) of risk

19. 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

20. ASSESSMENT OF HEALTH AND SAFETY RISKS Hierarchy of control measures for reducing risks in the work place. • Elimination • Substitution • 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

21. INFORMATION AND EDUCATION ON RISKS AND ADVICE ON THE NEED FOR PREVENTIVE AND CONTROL ACTIONS The information and education include the following aspects: • Workers in agriculture should have the right to be informed and consulted on OSH matters including risks from new technologies; and • The workers have a right to know and get continuously information on hazards related to their own work and the workplace. • The employer is responsible for training the workers on safe and healthy work practices.

22. INFORMATION AND EDUCATION ON RISKS AND ADVICE ON THE NEED FOR PREVENTIVE AND CONTROL ACTIONS • The workers have a duty to follow the safety instructions and safe and healthy work practices. • Confidential health information of an individual worker is subject to special legislation and practices and to informed consent. • The advice provided by OHS personnel must be given in a form which is easily understood by employers and workers. • Information given to various partners should be documented.

23. 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.

24. PREVENTIVE ACTIONS FOR THE MANAGEMENT AND CONTROL OF HEALTH AND SAFETY HAZARDS AND RISKS 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.

25. 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.

26. PREVENTION OF ACCIDENTS • 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.

27. PREVENTION OF ACCIDENTS • 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. • Safe tools and safety equipment for workers • Workers should use handholds when mounting and dismounting equipment. • Analysis of major hazard risks and provision of "redundant safety"

28. MAINTAINING PREPAREDNESS TO FIRST AID AND PARTICIPATION IN EMERGENCY PREPAREDNESS 1. Providing first aid services at the workplace when appropriate 2. Introducing and training first aid practices to workers and supervisors 3. Maintaining and periodically inspecting the first aid readiness and facilities 4. Participating from the health point of view in emergency planning and organizing the health elements in emergency response

29. DIAGNOSIS OF OCCUPATIONAL AND WORK-RELATED DISEASES 1. Identification of exposure which may cause the disease 2. Examination of clinical findings which are known to be associated with the specific exposure (lists of occupational diseases) 3. Exclusion of non-occupational factors as a possible cause of disease 4. Conclusion on existence or non-existence of occupational disease (diagnosis) 5. Statement on occupational disease for workmen's compensation 6. Proposals for preventive actions to the workplace of the worker in concern 7. Notification of occupational diseases to authorities

30. GENERAL HEALTH CARE, CURATIVE AND REHABILITATION SERVICES 1. Immunizations and other preventive measures 2. Participation in public health actions and programmes 3. GP-level general health services 4. Inspection and advice on canteens, sanitary facilities 5. Advice and education in general personal and community hygiene 6. Actions for rehabilitation and adjustment of work for workers after injuries, diseases, reduced work ability and on return to work from long sick leaves 7. General health promotion and introduction of healthy lifestyles

31. RECORD KEEPING 1. General health record, if the workers are treated as patients or health service clients 2. Data on surveyed, detected and measured occupational exposures and risk assessments made 3. Statistics on occupational diseases and injuries 4. Data on health examinations 5. Documents on proposals for preventive and control measures

32. EVALUATION 1. Evaluation is carried out as an inbuilt part of BOHS activity, at least annually 2. Evaluation is made when the working methods, production structures or other aspects at work are substantially changed 3. Evaluation is made if the methods or conditions of operation of services are substantially changed 4. The following questions are answered through evaluation: a) Do the services respond to the needs of the workplace? b) Are the activities directed to priority problems? c) Is good occupational health practice followed? d) Are the resources, human and technical, sufficient? e) Are the services effective in elimination of health problems? f) What can be improved?

33. Provision of BOHS • Primary health services model • Big company model with in-company services • Group services organized jointly, e.g. by several SMEs • Social security institution as a service provider • Private physician who has special competence in occupational health • Private health centre either providing occupational health services only or occupational health as a part of its services • Local or regional outpatient clinic of hospitals
