sand blasting silica

Abstract. Exposure to respirable crystalline silica is a hazard common to many industries in Alberta but particularly so in abrasive blasting. Alberta occupational health and safety legislation requires the consideration of silica substitutes when conducting abrasive blasting, where reasonably practicable.

Often the type of medium used in abrasive blasting will determine its type. The different types of sandblasting methods are listed below: Silica Sand or Silicon Dioxide. Silicon Dioxide refers to ordinary sand, which is also known as silica or quartz.

When blasting with silica sand, large clouds of dust will arise in the surrounding air. A crystalline silica dust particle of 2 microns drops only 1 metre per 24 hours, during windless conditions! This means that the dust-clouds remain invisibly in the air for a long time, long after the sandblasting is finished.

Abrasive blasting with sands containing crystalline silica can cause serious or fatal respiratory disease. The National Institute for Occupational Safety and Health (NIOSH) requests assistance in preventing silicosis and deaths in workers exposed to respirable crystalline silica during sandblasting.

BLACK BEAUTY ® blasting abrasives are a preferred alternative to silica sand. Silica sand can contain up to 99% free silica which has been found to cause silicosis, a sometimes fatal lung disease. BLACK BEAUTY ® abrasives are low dusting, chemically inert, contain less than 0.1% free silica and are not causally linked with any diseases, including silicosis.
