    “Drudgery reduction in use of improved chullah : an ergonomic approach
    (CCSHAU, 2009) Goyal, Neha; Mehta, Manju
    The present study was undertaken in Hisar district of Haryana state to determine feedback of improved chullah by the users and the physiological and environmental parameters while using improved chullah. A sample of 147 respondents from three villages was selected randomly for studying the acceptability of improved chullah installed through RHWE. Out of 147 respondents, 10 willing respondent were taken for second and experimental phase to determine the drudgery through physiological and environmental parameter. The survey of first phase revealed that majority of respondent were in between 38-50 years of age, illiterate, belongs to farming families, had nuclear families with 3-6 members, and belonging to high cast with monthly income Rs.1000-4000. Data showed that most of the respondent discontinued the improved chullah mainly because of economical restrains with total acceptability of 29.93%.However, the time expenditure was 2hrs. 23 min. on improved chullah in comparison to 3-4 hrs. on traditional chullah. Respondent selected for experimental evaluation and second phase were belonging to age group of 22-38 and 39-54 years. Majority of the respondents were in to mesomorph category.The assessment of drudgery revealed that increased PEFR and reduced heart rate in terms of physiological parameters with significant amount of drudgery reduction and low percentage of SPM, SO2, NO2/NO3 in smoke of improved chullah which decreases the risk of adverse effect on respiratory tract, lungs and defense mechanism. Use of improved chullah leads to cooking comfort, saving of time, less health hazards, smoke free kitchen and convenience resulting, in a better work environment.
