Title Abrasive Blasting Operations Program Effective Date 030175 Page 1 of 5 1 Status 1.1 Update of existing policy, effective 030711. 2 Purpose 2.1 Provide a safe working environment during abrasive blasting operations. We can accomplish this by understanding abrasive blasting hazards and the controls that can be implemented to
Silica sand This product is a potentially serious health hazard and should not be used as an abrasive. If silica containing quartz materials are selected for any reason, workers must wear a positive pressure or pressure demand respirator with an assigned protection factor APF of either 1000 or 2000.
The most severe silica exposures occur in abrasive blasting. Eliminating the silica means using a different, safer material in place of the silica-containing substance. It is true that in some cases it is not possible to use a substitute in place of silica, but for many operations, such as abrasive blasting, there are many possible substitutes ...
However, there is evidence that silica sand suspended as a hydrosol i.e in water can penetrate the respiratory track easier then an aerosol i.e. in air. So although blasting with wet sand will initially keep the dust down, it will not repress it to the maximum exposure limit of 0.3 mgm expressed as an 8-hour time-weighted average.
