Reduction of dustiness at non-stationary workposts

Ograniczanie zapylenia na niestacjonarnych stanowiskach pracy

M. Gliński

Abstract

Many industrial processes are responsible for chemical and dust pollution. As the quantities of the substances emitted remain unknown in most cases, the data on the effect of technological parameters on the emission rates are not available. Various technical and organisational projects aimed at reducing dust hazards in rooms and at workposts are listed. Methods of assessing emission rates of pollutants from machines to the workplace air, and the efficiency of local exhaust ventilation are discussed. Results of the study in this area for a manual mechanised tool grinder and a tool grinder machine are presented.
