Dry ice blasting is a relatively new form of blasting which most have heard of though few are familiar with. The most advantageous aspect of dry ice blasting is the savings to you. In fact, the typical operator sees a dramatic increase in productivity and an equally impressive drop in costs. With this type of blasting, dry ice pellets are accelerated by a jet of compressed air similar to typical blasting. The difference, however, is this method of blasting is more delicate approach than the sledgehammer approach to conventional blasting.

In general, a blast room consists of an enclosure, control panel, pressure vessel, blast equipment (nozzle, couplings, hose, safety controls), media reclaimer, pressure blower for media recovery, dust collector for abrasive recovery, media conveying duct, media recovery hopper, media storage hopper, and blast booth ventilation.
The design criteria required for a properly sized blast room system includes the size of the largest workpiece, the weight of the largest workpiece, the material handling method, the number of hours of blasting per day, and the base material of the workpiece. Each of these items needs to be addressed in order to finalize the configuration of the blast room.
Welders, health organizations and management are all becoming increasingly concerned with the effects of welding smoke and fumes in the work place. In addition, management is becoming increasingly conscious of the costs of absenteeism and reduced productivity resulting from illness caused by polluted air. There is little doubt that welding is one of the leading causes of in-plant air pollution in industry.
The Labor Department reduced the acceptable levels of workplace exposure Monday to a cancer-causing metal, hexavalent chromium, but critics said the new standard still leaves thousands of workers at risk. The new rule limits worker exposure to the carcinogenic metal to no more than 5 micrograms per cubic meter of air, a large reduction from the old standard, but also a level five times higher than what had been proposed by the agency two years ago.
