In India, the manual brick making process is physical demanding jobs where millions of workers earn their livelihood. The study attempts to improve the organization of the work in brick manufacturing units and makes operations for the betterment and enhances its productivity. Observation studies and posture analysis were performed among them by the OWAS method. A detailed plan and time study were done, and accordingly, modifications of the processes were also carried out. The body mass index (BMI) of both groups of brickfield workers was 18.58 (±2.53) (brick molders) and 19.24 (±2.72) (brick carriers) respectively, suggesting that the workers had a normal range of BMI. Working postures of brickfield workers are of high risk as indicated by the OWAS system. In this study, an attempt was made to organize the manual brick making operation for enhancing productivity. The existing process of Brick making involved some unnecessary steps, which hamper the rate of work and consequently productivity, is also affected. This study eliminates the real steps and enhances 32% productivity in time and also recommends the ergonomic intervention to reduce biomechanical stress among brickfield workers.
