The hazardous substances screening by means of the local suction ventilation which element is the local suction gun is regarded in the article. The inuence was investigated of the size ratio between the suction gun and he ring opening dimensions, as well as of the drawn in-incoming air ratio on both of the suction gun's air gripping distance and on the dust ow reducing in the local closed type suction guns. The local suction guns were regarded in the unrestricted, half-restricted and restricted spaces.Ill.3. Ref. 20.
