Ludhiana, October 4
“Aspects like safety and comfort of the operator must be given prime attention since farm machines involving drudgery are not accepted by the people. The machines should also be environment friendly,” said Dr K.S. Aulakh, Vice-Chancellor of Punjab Agricultural University, while addressing delegates at the inaugural function of the two-day workshop on the Indian Council of Agricultural Research’s (ICAR) all-India coordinated research project on “human engineering and safety in agriculture”, here today.
Dr Aulakh highlighted the role of the PAU in the field of agricultural mechanisation in raising agricultural production and productivity and reducing the cost of cultivation. He appreciated and recalled the role of agricultural engineers at the PAU for doing pioneering work in designing the safe feeding chute in the late seventies which resulted in enactment of parliament law, Dangerous Machines (Regulation) Act, 1983.
Adoption of these standards have resulted in reduction in thresher accidents to the bare minimum. He mentioned that the frequency of accidents for self-propelled machines, tractors, threshers, chaff-cutter, sprayers and cane-crushers in Punjab has reduced considerably because of better awareness and training imparted to the users. At present it is only 0.74 accidents per thousand machine per year as against more than two accidents per 1000 machines at the national level.
He stressed that the tractor industry should reduce the noise level in tractors to less than 90 decibals which is above 95 decibals now. Similarly, tractor seat vibrations are causing serious health problems like backache, stomach, neck, hand and eye problems. About 88 per cent of the operators reportedly suffer stomach problem due to vibrations.
Dr Aulakh said harvesting combines are found to have respirable suspended particles (RSP) in the range of 1,333 to 2,390 micrograms per meter cube as against safe, alarming and dangerous levels of 250, 500 and 1000 micrograms, respectively. He advised the researchers to take this factors into consideration, while improving work efficiency, productivity and safety and reduction in cost of production at the farm.
Dr Anwar Alam, Deputy Director General (Engg), ICAR, in his presidential remarks mentioned that food production in the country has increased beyond 200 million tonnes. Farm mechanisation is a very important and crucial component in this process. It would be relevant to understand the role of human engineering without which the man- machine system will result in lower machine efficiency, more fatigue and increased number of farm accidents. He mentioned that agriculture mechanisation is rapidly penetrating into eastern, western and southern regions of the country. Dr Alam further said that the safety of the operator starts right from the designers’ table because any minor fault in the design of machine cause serious hazards accidents.
Dr G.S. Nanda, Director, Research, PAU, highlighted the role of farm machanisation in the state in providing self sufficiency to the production of foodgrain, milk, fisheries, honey and others. He said the principle underlying human engineering concepts includes increasing work efficiency, safety and productivity at the same time decreasing accidents, time requirements and making the work environment comfortable and easy.
He mentioned that every day one hears about accidents caused by the tractors due to the overloaded tractor-trailer filled with sugarcane, straw or other crop produce. Those accidents can be avoided using roll-over protection structures (ROPS) which are mandatory in countries like the USA. A large number of accidents also take place while using sprayers and electric motors. The state government through the state marketing board extends monetary help victims to the tune of Rs 75, 000 in te case of death or permanent disability.
Human engineers can foresee such situations and can provide preventive features to minimise these accidents because human life is very precious. More than 200 million workers are engaged in agriculture and allied activities in the country and ergonomics can play a major role to increasing work efficiency and productivity these workers without jeopardising their health and safety, he pointed out.
Dr N.S.L. Srivastava, Assistant Director General (Engg), ICAR, while talking about the role of all-India coordinated research project on human engineering and safety in agriculture, said that the mandate of the project is to create databases on ergonomical parameters of Indian agricultural workers and to develop on adapt the equipment on technology on work system for increasing production, reducing drudgery and minimising the accidents in agricultural and allied activities through application of ergonomics.
