May have several hazards associated with it at any given time. Abrasive blasting is more commonly known as sandblasting since silica sand has been a commonly used material as the abrasive, although not the only one always used. Abrasive blasting entails accelerating a grit of sand sized particles with compressed air to provide a stream of high velocity particles used to clean metal objects such as steel structures or provide a texture to poured concrete. This process typically produces a large amount of dust from the abrasive, anything on the substrate being abraded, and/or the substrate itself.
If the process is not completely isolated from the operator, abrasive blasting dusts are a very great health risk. Respirable dust from silica sand and other abrasive materials pose a risk to the lungs. Where abrasive blasting is used to remove lead-based paint on the steel infrastructure of bridges, it can generate particles of lead that pose a risk to the nervous system. In addition to potential health hazards, abrasive blasting can pose safety risks as well. Cleaning steel while working from scaffolding introduces a fall risk and from within industrial tanks a confined space risk
