For decades abrasive blasting has been used in the manufacturing industry. Almost all metal work requires a clean surface to work on. Rough surface or any contaminants on the surface is trouble for any manufacturer. Thanks to the effective process of abrasive blasting, any type of paint, oil, rust and other debris can be easily removed to get a clean surface.

The use of abrasive blasting is not limited to removing dust and other common debris. It is also used to remove harmful materials like radioactive materials, asbestos, lead, zinc and other hazardous materials.

The process of abrasive blasting involves propelling of abrasive material under high pressure to get a smooth surface. Usually a centrifugal wheel is used to blast the material. There are many different types of blasting processes; wet blasting, bead blasting, bristle blasting, dry ice blasting, wheel blasting, sand blasting, shot blasting and soda blasting.

The huge industrial abrasive blast equipment is used by large scale manufacturing units while there is a smaller version the equipment called portable blast system. These are fuelled by a mixture of diesel and compressed air. The portable blast system has a blast pot just like its larger version that can sustain high pressure.

Workers who work with abrasive blasting equipment and dust collectors have to wear appropriate protective gears like work goggles, protective suit, work gloves and shoes. The abrasive blasting systems are noisy equipment so, workers should also use ear buds for the protection from ear damage caused due to excess exposure to sound.

The dry abrasive blasters produce a lot of dust as a waste product. If any toxic material is involved in the process then there are high chances of the worker breathing in chemicals that if inhaled may cause lungs illness or/and permanent damage. Ensure that industrial dust collectors are installed to keep the air free from toxic material. The dust collector system should be installed on the ground and not suspended in air to prevent static discharge which may trigger potential fire.

The best thing about abrasive blasting is that it does not use any chemicals. By using the combination of air or water and natural substances like sand or glass manufacturers can get clean and smooth metal surface to work on. This is an environment friendly process that helps us to make the planet a greener place to live in. Furthermore, it is a very cost effective method to get the work done in a very short span of time with amazing finish.

I didn't know that blasting was used for asbestos...nasty stuff no matter what tho.

It goes without saying that protective gear is critical with abrasive blasting.

Yeah, my office building is filled with asbestos...someone in management should do something about it.
