| Abstract | ||||
| Paper Dust is defined as fine particles of paper fibres, its fibrils and its powder or it is the particles of paper filler material which is falling during the process of passing paper reel in web litho-offset printing machineor during transfering paper sheets to printing machines or during shredding of scraps of paper resulting from shearing or trimming or Slit or Punching. Paper dust causes many health problems and thorax diseases to be treated to varying degrees according to several variables, including source distance, exposure periods, inhaled quantity, and particle properties such as size, shape, density and chemical composition. Paper dust particles maximum exposure limits in accordance to the Egyptian ministerial act no. (211) of 2003 year equals 10 milligram / m3 every 8 hours. So the aim of this research is to introduce several available engineering solutions to protect workers from the health risks resulting of exposure to paper dust which are as follows: Ventilation , Dust Collectors installation, Water Mist, and Respiratory protective Equipment (RPE), in addition to ensuring the optimal selection of filters used in it and their suitability to the material and its concentration on air surrounding the workers. | ||||
