How to Control Dust from Abrasive Blasting


Abrasive blasting is used in several industries and one thing is common to all; the dust that it causes. Even though the dust particles that result will differ according to the material being blasted, all can create an unhealthy work environment unless measures are undertaken to reduce the dust. This can only be done with the proper dust extraction and control equipment.

Dust in the atmosphere can cause skin rashes, breathing difficulties and even lung cancer over time if it is not controlled. Since no company wants to lose their employees in this way or be liable to litigation, it is essential to install the right equipment to remove the dust and ensure the environment is clear and clean. This can only be done by consultation with experienced professionals in the field of dust control.

What is installed will depend a great deal on the size of the work area and the kind of material that is undergoing abrasion. Some materials will form fine powder type dust, while others will have larger particles that need to be removed from the atmosphere. Even though workers will be wearing protective masks, large particles can still be inhaled and cause many problems. Fine particles will cling to clothing and become a problem even after the work is finished.

Abrasive blasting must be done to ensure the products are cleaned and ready for the next stage, but unless those who are working on it take proper precautions their lives could be in danger from the fumes and dust that soon flies into the atmosphere. While the first step is to wear protective clothing such as goggles and masks, every company must put controls into place to make the workplace safer.

There are many different kinds of dust control and dust extraction systems ranging from reverse air dust collectors to fog dust control systems and more. Fine particulate scrubbers that use very little water and no chemicals do a good job on removing the finest dust that can hang in the atmosphere where the work is being carried out.

The fog works by having water droplets the same size as the dust particles so that they are actually absorbed by the water when both collide with each other and so are prevented from flying up into the atmosphere where they cannot be controlled. This controls those fine dust particles in the 0 to 10 micron range that are the most dangerous to human health. The technology works even in normal cold conditions because the tiny water droplets do not freeze.
