Devices to Protect Sand-Blaster Against Dust Hazard.-This is a study of the efficiency of certain devices used for protecting workers in the sand-blasting process. The study was made in a plant where the sandblast was used upon automobile parts. The process was done in the usual cabinets having an exhaust and with hoppers below. The operators were provided with the usual "muzzle" type of rubber respirator with a piece of sponge and an air valve, also with helmets. The Palmer water-spray apparatus was used for dust countinlg; highest counts for dust ever reported were obtained from within the sand-blast cabinet (an average of over 16 million particles per cubic feet). It was found that the respirator removed about 92 per cent 'of the dust by counit and 97 per cent by weight. The combination helmet respirator gave distinctly better results but counts were still far in excess of the limits to be considered safe. The combination of respirator and helmet provided with positive air pressure (from 2.3 to 3.7 cubic feet per minute) greatly reduced the amount of dust caught within the helmet and brought about a condition
