An ergonomic study on teenage girls working in the manual brick manufacturing units in the unorganized sectors in West Bengal, India

There are laws which protect and prevent the teenage girls from working. But still in the developing countries like India, Bangladesh, etc. teenage girls coming from low socio-economic background work, to add to the family income. There is dearth of data regarding the ergonomic studies of the teenage girls working in the manual brick manufacturing units of the unorganized sectors in India. Therefore, a field study was conducted in about four brick manufacturing units of West Bengal, India. Their job in these fields was to carry 8-10 unbaked and sun-dried bricks (49.11 +/- 2.13 Kg) from the brick field to the kiln-top and again carry the baked bricks back from the kiln to some other corner of the brick field, under the hot sun. Thus, this study aimed at evaluating their work load and their consequent work-related health effects. Results show that 86 % of them suffered from work-related pain in different body parts and there was an increase in their physiological and psychological parameters after work. It is concluded that the frequent use of awkward postures while at work (OWAS) and performing heavy to moderate types of tasks in the field are deteriorating their health conditions.
