The typical south Indian saw mill comprises of a general manager in charge of the plant, assisted by the plant superintendent. The following men report to the superintendent: saw mill foreman, master mechanic, bookkeeper, and shipping clerk. Most work at the saw mill is done manually without much use of powered vehicles. In nearly 80 sawmills in this region all movement of the logs from unloading section to the carriage, from carriage to the delivery point is done manually, many such manual activities were observed for few minutes to 2 hours at a stretch for both seated and standing position of the workers. The work involved predominant effort from the trunk and arms. The work in a typical saw mill starts right from the unloading of raw wooden logs (up to 5 quintals) into the unloading section of the mill. Then these logs are moved to the horizontal band saw with the help of levers as shown in figs. 1 & 2.
