Sandblast is a particular term which is technical in nature. It is a term that is closely related to industrial work. Sandblast means to blast a surface with abrasive particles and this way it is made clean and clear and then it can be used for many purposes.
Sandblast is a special task that can not be done by non professionals. Prior training is mandatory in order to make somebody good sandblaster operator. Training does not extend for more than a few weeks but it covers all the aspects which include operational aspects as well as safety aspects of the sandblasting.
Operational aspects are necessary to learn in order to perform a successful sandblast operation but safety aspects are also a must because they can save lives. Sandblasting involves life risk as it can cause fatal diseases like Asthama and more dangerously Silicosis which is incurable. Silicosis is a very dangerous disease and once diagnosed of Silicosis patient never get better. He continuously get ill and more ill and finally loses his life.
I have made my point several time in my online presence that how to safe ones ownself from these fatal diseases. Silica substitutes are available that can eradicate any chances of Silicosis and breathing protection should also be used in order to protect from these sandblast diseases.
