After taking all possible measures still the dust level in packing area is alarming. In packing plant dust concentration as well as % of fineness of dust is more concerning. The fineness of cement dust is avg . <2.51-Jm which consist of ,- >25% of dust present in PPP. Therefore settling time of dust is more than 1hr and avg. working time in this area is 6.0hrs per day of individual person. Therefore ingestion of dust by individual person per day is - 61g. Thus keeping dust under workplace exposure limit (WEL) is challenging and is required to be maintained for sustainable development. 20 10 0 Fig-7 - Reduction in SPM • Ventilation and Dilution consists of renewing the air of premises • Sufficient ventilation by providing adequate size window and exhaust • Minimum travelling distance of cement bag from packer to truck/ wagon • Transverse point with minimum jerk and fall • Reduce the falling height at loading point, avoid sharp edge at transfer • Cement bag density and tensile strength to prohibit bag burstage • Upkeep of packer machine, weighing sensor and entire loading system • Ensure 100% efficiency of Air Pollution Control Equipment. 2.8 Welding and Soldering operation The welding and soldering are activities which might happens during fabrication , erection , maintenance of plant.
