#0183;#32;Risks of Silica Sand Silica sand is a very abrasive material making it effective at quickly profiling a product surface but the problem is that when it hits a products surface it fractures into very tiny particles. These tiny particles are so small that even proper sandblasting respirators are not necessarily sufficient enough to prevent inhalation.
In the past, I talked about the different kinds of sand used for a sandblaster which stated that play sand has silica in it. That was one of the reasons why I suggested that people should not use it.

The media also causes corrosion on the sides of a blast gun which leads to faster wearing and tearing of use of silica for abrasive blasting is also not economical since the media can only be used once or twice.
