This study focuses on developing a safe workplace for agricultural tractor drivers and recommending the optimum location for tractor control. Thirteen anthropometric body dimensions of 8,025 Indian male agricultural workers were considered for developing reach envelopes for hand- and foot-operated controls. The optimum reach for hand controls is in the range of 456 to 700 mm forward and 265 to 492 mm above the seat reference point. Similarly, for foot-operated control, the foot could reach within the range 429 to 897 mm forward and 367 mm below, and 30 mm above the seat reference point.

Most of the agricultural operations in India are performed manually with hand tools and equipment by female agricultural workers. This prompted designers to use female anthropometric data in designing of farm equipment and workplaces in order to reduce drudgery, to enhance safety, to improve performance, productivity and efficiency. A study was conducted to collect the anthropometric data of selected 30 female agricultural workers in the age group of 22-54 years from Madhya Pradesh state. For design of agricultural tools, equipment and workplaces the important, thirty eight body dimensions including weight were identified and measured. The values of mean, standard deviation (SD), minimum, maximum, coefficient of variation (CV) and 1st, 5th, 50th, 95th and 99th percentile values were calculated of selected body dimensions. The mean weight and stature of female agricultural workers were found to be 53 kg and 1536 mm, respectively. A large variation in anthropometric dimensions in the anthropometric data of female farm workers of different states of India and other countries was observed. Pearson correlation coefficients (PCC) were calculated among selected anthropometric dimensions of subjects. The correlation coefficients of measured data varied from 0.65-0.98.

Study Results

A comparative analysis of the anthropometric body dimensions of the male and female agricultural workers was conducted in South-Eastern Nigeria to ascertain the variations that exist among the body characteristics/dimensions of the male and female agricultural workers in the area. Thirty (30) anthropometric dimensions considered useful in the design of the agricultural equipment alongside with the heart rate of the workers were studied. Male and female agricultural workers within the age limit of 20-60 years were used for the study. Results obtained revealed that male agricultural workers had greater body dimensions than the females except in the waist circumferences and hip breadths in which the male measured average of 81.1cm and 34.4cm respectively and the female recorded 88.7cm and 42.1cm at waist and hip regions respectively. The comparison further showed that male agricultural workers had average stature and body weight of 168.3cm and 65.9kg respectively with the 5th and 95th percentiles of 162.75cm and 175.77cm respectively in stature; and 60.15kg and 71.73kg in body weight respectively. While the female recorded mean stature and body weight of 163.2cm and 64.8kg respectively with the corresponding 5th and 95th percentiles of 153.96cm and 172.17cm respectively in stature and 60.04kg and 69.35kg respectively in body weight. The males had average heart (pulse) rate of 73.8 beats/min while the females had 70.5 beats/min. The comparison generally did not show much variations, which implies that implements/machine designed for the male workers could suit the female workers or might be adjusted to suit the female workers.  http://dx.doi.org/10.4314/njt.v36i1.31

The Way

Abstract. In this work, we investigated individual differences in cognitive reflection effects on delay discounting – a preference for smaller sooner over larger later payoff. People are claimed to prefer more these alternatives they considered first – so-called reference point – over the alternatives they considered later. Cognitive reflection affects the way individuals process information, with less reflective individuals relying predominantly on the first information they consider, thus, being more susceptible to reference points as compared to more reflective individuals. In Experiment 1, we confirmed that individuals who scored high on the Cognitive Reflection Test discount less strongly than less reflective individuals, but we also show that such individuals are less susceptible to imposed reference points. Experiment 2 replicated these findings additionally providing evidence that cognitive reflection predicts discounting strength and (in)dependency to reference points over and above individual difference in numeracy.

The Worker Protection Standard (WPS) is a Federal regulation designed to protect agricultural workers (people involved in the production of agricultural plants) and pesticide handlers (people mixing, loading, or applying pesticides or doing other tasks involving direct contact with pesticides).There are certain exemptions in the WPS rule that have been revised pertaining to agricultural establishment owners and their immediate family members. This fact sheet explains these new provisions.

General Guidance

The Worker Protection Standard (WPS) is a Federal regulation designed to protect agricultural workers (people involved in the production of agricultural plants) and pesticide handlers (people mixing, loading, or applying pesticides or doing other tasks involving direct contact with pesticides). It has been in full implementation since 1995. This document provides general guidance to help you comply with the requirements of the Federal Worker Protection Standard (WPS) for agricultural pesticides, 40 CFR part 170, as amended in 2015. This document addresses specific information that agricultural establishments must display at a central location for their employees.
