Blast Rooms – The Basics

Blast rooms are available in many sizes and configurations. 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. Operator safety equipment is also required for blast operation. Prefabricated / Pre-Engineered / Pre-Designed Pre-engineered and prefabricated blast rooms offer quick delivery turnaround and cost savings. Pre-made blast rooms are typically available in 8-ft to 15-ft widths with 8, 10 or 12 foot ceiling heights and…

The Blasted News: Dry Ice Blasting

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.

How to Create an Abrasive Blast Room

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.

A Primer on Welding Smoke and Fume Control

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.

OSHA Issues New Workplace Rule on Chromium

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.

New Abrasive Metering Valve Shows What Matters

The days of open abrasive blasting, with minimally trained operators using loads of cheap abrasive are dwindling in the United States. Environmental, safety, and health regulations, combined with demanding surface profile requirements, mean that abrasive blasting is often being performed in containment by skilled operators using higher priced media.
